Purpose There is no evidence of a dietary index that measures not only the quantity but also the quality of protein. The aim is to investigate the association between a new dietary protein quality index (PQI) and micronutrient intake adequacy in a Mediterranean cohort. Design We assessed 17,535 participants' diet at baseline using a semi-quantitative FFQ. The PQI was calculated according to the ratio of protein (g/d) sources: [fish, seafood, lean meat, pulses, eggs, nuts, low-fat dairy, and whole grains]/[red and ultra-processed meats, whole-fat or semi-skimmed dairy, potatoes and refined grains]. Participants were classified into quintiles of PQI. We evaluated the intakes of Fe, Cr, I, K, Mg, Ca, P, Na, Se, Zn and vitamins A, B1, B2, B3, B6, B12, C, E and folic acid. Micronutrient adequacy was evaluated using DRIs. Logistic regression analysis was used to assess the micronutrient adequacy according to quintiles of PQI. Results In this cross-sectional analysis, a total of 24.2% and 4.3% participants did not to meet DRIs in >= 4 and >= 8 micronutrients, respectively. The odds of failing to meet >= 4 and >= 8 DRI were lower in participants in the highest quintile of protein quality (OR = 0.22; IC 95% = 0.18, 0.26; P-trend < 0.001; and OR = 0.08; IC 95% = 0.05, 0.14; P-trend < 0.001, respectively) as compared to participants in the lowest quintile. Conclusion Higher PQI was found to be strongly associated with better micronutrient intake adequacy in this Mediterranean cohort. The promotion of high-quality protein intake may be helpful for a more adequate intake of micronutrients. The odds of failing to meet certain numbers of DRIs were lower rather than saying lower risk.

Purpose We aimed to prospectively investigate the association of an overall oxidative balance score (OBS) with all-cause death and cause-specific mortality among participants in the Seguimiento Universidad de Navarra (SUN) Study, a Mediterranean cohort of Spanish graduates. Methods Using baseline information on 12 a priori selected dietary and non-dietary lifestyle pro- and antioxidants exposures-vitamins C and E, beta-carotenes, selenium, zinc, heme iron, polyphenols, total antioxidant capacity, body mass index, alcohol, smoking, and physical activity-we constructed an equally weighted OBS categorized into quartiles, with higher scores representing greater antioxidant balance. Cox proportional hazards models were fitted to evaluate the association between the OBS and mortality. Results A total of 18,561 participants (mean [SD] age, 38.5 [12.4] years; 40.8% males) were included in the analysis. During a median follow-up of 12.2 years (interquartile range 8.3-14.9), 421 deaths were identified, including 80 deaths from cardiovascular disease (CVD), 215 from cancer, and 126 from other causes. After adjustment for potential confounders, the hazard ratios and 95% confidence interval (CIs) between the highest quartile (predominance of antioxidants) vs. the lowest quartile (reference category) were 0.35 (95% CI 0.22-0.54, P-trend < 0.001) for all-cause mortality, 0.18 (95% CI 0.06-0.51, P-trend = 0.001) for CVD mortality, 0.35 (95% CI 0.19-0.65, P-trend = 0.002) for cancer mortality, and 0.45 (95% CI 0.20-1.02, P-trend = 0.054) for other-cause mortality. Conclusion Our findings suggest a strong inverse association between the OBS and all-cause, CVD, and cancer mortality. Individuals exposed to both antioxidant dietary and lifestyle factors may potentially experience the lowest mortality risk.

Several studies have tried to analyse the association between all-cause mortality and different risk factors, (especially those which are modifiable, such as smoking, diet or exercise), to develop public health preventive strategies. However, a specific analysis of predictors of premature and late mortality is needed to give more precise recommendations. Considering that there are risk factors which exert an influence on some diseases and not on others, we expect that, similarly, they may have a different impact depending on the timing of mortality, separating premature (<65 years) from late mortality (>65 years). Thus, we prospectively followed-up during a median of 12 years a cohort of 20,272 university graduates comprising an ample range of ages at inception. Time-dependent, covariate-adjusted Cox models were used to estimate adjusted hazard ratios (HR) and their 95 % confidence intervals (CI) for each predictor. The strongest independent predictor of mortality at any age was physical activity which was associated with reduced risk of total, premature and late mortality (range of HRs when comparing the highest vs. the lowest level: 0.24 to 0.48). Specific strong predictors for premature mortality were smoking, HR: 4.22 (95 % CI: 2.42-7.38), and the concurrence of >2 metabolic conditions at baseline, HR: 1.97 (1.10-3.51). The habit of sleeping a long nap (>30 min/d), with HR: 2.53 (1.30-4.91), and poor adherence to the Mediterranean Diet (<3 points in a 0 to 8 score vs. >6 points), with HR: 2.27 (1.08-4.76), were the strongest specific predictors for late mortality. Smoking, diet quality or lifestyles, probably should be differen-tially assessed as specific predictors for early and late mortality. In the era of precision medicine, this approach will allow tailored recommendations appropriate to each person's age and baseline condition.

Background & aims: The specific association of olive oil consumption with coronary heart disease (CHD) or stroke has not been totally established. Objective: to examine whether olive oil consumption is associated with subclinical atherosclerosis, the risk of total cardiovascular disease (CVD), CHD, and stroke. Methods: Three cohorts were included: AWHS (2318 men), SUN Project (18,266 men and women), and EPIC-Spain (39,393 men and women). Olive oil consumption was measured at baseline using validated questionnaires. Results: In the AWHS, 747 participants had a positive coronary artery calcium score (CACS>0), and the OR (95% CI) was 0.89 (0.72, 1.10) in those with virgin olive oil consumption >30 g/day (v. <10 g/day). In the SUN Project (follow-up 10.8 years) 261 total CVD cases occurred, and the HR was 0.57 (0.34, 0.96) for consumptions >30 g/day (v. <10 g/day). In the EPIC-Spain (follow-up 22.8 years) 1300 CHD cases and 938 stroke cases occurred; the HRs for stroke according, 0 to <10 (ref), 10 to <20, 20 to <30, and >30 g/day of olive oil consumption, were 0.84 (0.70, 1.02), 0.80 (0.66, 0.96), 0.89 (0.74, 1.07). A weaker association was observed for CHD. The association was stronger among those consuming virgin olive oil, instead of common (refined). Conclusions: Olive oil is associated with lower risk of CVD and stroke. The maximum benefit could be obtained with a consumption between 20 and 30 g/day. The association could be stronger for virgin olive oil and might operate from the early stages of the disease.

Objectives To evaluate the association between cancer screening counselling provided by medical doctors to their patients and each doctor's own anthropometrics, lifestyle, cancer screening practices, and personal and family history of cancer. Design Prospective cohort study. Setting Substudy including physicians participating in a Spanish cohort study with open enrolment. Participants Among 22 800 participants in the cohort as of May 2018, there were 2371 physicians who had replied to the cohort baseline questionnaire, had an email account and were younger than 65 years (retirement age in Spain). From this subsample, 890 replied to an online questionnaire focused on their clinical practices related to the counselling provided to their patients and to their prescription practices of preventive medications. Their mean age was 51.7 (SD 9.4) years and 48% were women. Outcome measures Frequency of counselling given to their patients on specific practices of breast, colorectal and prostate cancer screenings. Results Counselling on cancer screening to their patients was provided by 65% of physicians in a scenario of colorectal cancer, 59% for prostate cancer and 58% for breast cancer. More frequent cancer screening counselling was associated with the specialties of family medicine (OR=9.4, 95% CI 5.1 to 17.1) and internal medicine (OR=2.9, 95% CI 1.5 to 5.7) as compared with other specialties. Recommending cancer screening was associated with more frequent counselling on smoking cessation (OR=3.7, 95% CI 2.6 to 5.4), having personally attended colorectal cancer screening (OR=2.2, 95% CI 1.1 to 4.7) and prescribing blood pressure medication more often than their colleagues (OR=2.1, 95% CI 1.2 to 3.7). Conclusions Among medical doctors, cancer screening counselling was provided to their patients more frequently for doctors with family medicine or internal medicine specialties and for physicians who regularly offered counselling on certain lifestyle behaviours, and those having personally attended colorectal cancer screening. Doctors' own personal practices and knowledge of healthy lifestyles may help doctors to more frequently provide counselling on cancer screening to their patients.

Background: Dietary quality indices (DQI) are widely used in nutritional epidemiology. However, how they might change over time in a Mediterranean population is not well understood. Objective: To evaluate within-participant longitudinal changes in scores for nine a priori¿defined DQIs: Fat Quality Index (FQI), Carbohydrate Quality Index (CQI), Pro-vegetarian Dietary Pattern (PVG), Mediterranean Diet Adherence Screener (MEDAS), Mediterranean Diet Score (MDS), Dietary Approaches to Stop Hypertension (DASH), Mediterranean-DASH Intervention for Neurodegenerative Delay Diet (MIND), Prime Diet Quality Score (PDQS) and Alternate Healthy Eating Index (AHEI-2010) in the ¿Seguimiento Universidad de Navarra¿ (SUN) cohort, a well-known Mediterranean cohort of university graduates, and to identify baseline predictors of improvement in MEDAS and AHEI-2010 after 10 years of follow-up. Design: In this longitudinal cohort study, DQI scores were calculated based on responses from a validated semiquantitative food-frequency questionnaire (FFQ). Participants/setting: Spanish university graduates enrolled in the SUN cohort before March 2008, who completed the 10-year FFQ and reported total dietary intake at baseline and after 10 years of follow-up, included 2,244 men and 3,271 women, whose mean age at baseline was 36.3 years (standard deviation [SD], 10.7). ...

Background & aim: The association between ultra-processed foods (UPF) consumption and the risk of type 2 diabetes (T2D) has not been much explored. We aimed to evaluate the association between consumption of UPF and the incidence of T2D. Methods: We assessed 20,060 participants (61.5% women) from the SUN project (Seguimiento Universidad de Navarra) followed-up every two years (median follow-up 12 years). Food and drink consumption were evaluated through a validated 136-item food frequency questionnaire and grouped according to their degree of processing by the NOVA classification. Participants were categorized into tertiles of UPF consumption adjusted for total energy intake. We fitted Cox proportional hazard models with repeated dietary measurements at baseline and updating information on food consumption after 10 years of follow-up to minimise the potential effect of diet variation. Results: During 215,149 person-years of follow-up, 175 new-onset T2D cases were confirmed. Participants in the highest baseline tertile (high consumption) of UPF consumption had a higher risk of T2D as compared to those in the lowest tertile (multivariable adjusted hazard ratio [HR] 1.53, 95% confidence interval [CI]: 1.06 to 2.22) with a significant dose-response relationship (p for linear trend 1/4 0.024). The multivariable adjusted HR using repeated measurements of UPF intake was 1.65 (95% CI 1.14-2.38) when comparing extreme tertiles. Conclusions: In a highly-educated Mediterranean cohort with a low absolute risk, a higher intake of UPF was independently associated with a higher risk for T2D. These results provide more evidence to encourage the limitation of UPF consumption to reduce the population burden of T2D.

Background and objectives: Cured ham is one of the most characteristic foods in the Spanish diet. Because it is a red processed meat and due to its nutritional composition, including high sodium content, a potential association between cured ham consumption and a higher risk of hypertension could be expected. However, epidemiological studies evaluating this association are scarce. We prospectively assessed the association between cured ham consumption and the incidence of hypertension.
Methods: The "Seguimiento Universidad de Navarra" (SUN) study is a cohort of Spanish middle-aged adult university graduates (average age: 38 (SD: 12) years, 60% women). We included 13,900 participants of the SUN cohort free of hypertension at baseline. One serving of cured ham is 50g. They were classified into 4 categories of cured ham consumption: <1; 1; 2-4 and ¿5servs/week. Multivariable-adjusted Cox regression models were fitted to assess the association between cured ham consumption and subsequent hypertension risk using the category of lowest consumption as the reference.
Results: After a median follow-up of 10.9 years, 1465 incident self-reported cases of hypertension were identified. After adjusting for potential confounders, including dietary confounders, a high consumption of cured ham (¿5servs/week vs. <1serv/week) was not significantly associated with hypertension risk in this prospective cohort (HR=0.88, 95% CI: 0.70-1.10, p linear trend=0.40).
Conclusions: Our results showed that cured ham consumption was not associated with a significantly higher or lower risk of hypertension in a prospective cohort of Spanish middle-aged adult university graduates. Further longitudinal and experimental studies are needed to disentangle the association between cured ham consumption and the risk of hypertension.

Background: Healthy lifestyle adherence is associated with lower chronic disease morbidity/mortality. The role of doctors, as counselors and role models, is essential. Among physicians participating in a prospective cohort, we investigated the behavioral counseling on diet and lifestyle provided to their patients in association with their own personal behaviors.
Methods: We assessed 890 doctors aged ¿65 years participating in the 'Seguimiento Universidad de Navarra' (SUN) cohort, who replied to an online questionnaire regarding their practices on behavioral counseling and drug prescription to their patients. Data were combined with previous baseline information on their personal healthy habits.
Results: Among doctors, 31% reported <10 min per visit; 73% counseled 60-100% of their patients on smoking cessation, 58% on physical activity, 54% on weight control, 51% on healthy nutrition, 44% on alcohol avoidance/reduction and 28% recommended alcohol moderate consumption. The percentage of doctors that counseled 100% of their patients about lifestyle was 43% for smoking cessation, 15% for exercise and 13% for weight control and nutrition. Better doctor's adherence to the Mediterranean dietary pattern was associated with more frequent and longer nutrition counseling. Higher practice of physical activity was associated with longer time on counseling about exercise to their patients. Among doctors both current and former smoking were inversely associated with the frequency and duration of their smoking cessation/avoidance counseling practices.
Conclusions: Personal behavioral changes among doctors and better training of medical doctors on a personal healthy diet and lifestyle are likely to contribute to improve the behavioral counseling given to patients.

Dietary guidelines play a key role in setting standards for nutrition policies and promoting healthy eating. Like other public health guidelines, they are often influenced by political and economic factors that could place other concerns ahead of the population's health. In order to determine their effectiveness on obesity prevention, we prospectively examined the association between adherence to the latest available national dietary guidelines and the incidence of overweight/obesity in a Spanish cohort study. A sample of 11,554 participants of the "Seguimiento Universidad de Navarra" (SUN) cohort, initially free of overweight or obesity, was included in the study. The Spanish Society of Community Nutrition (SENC) food pyramid (FP) score was computed based on the ratio of consumed to recommended daily servings of grains, fruits, vegetables, dairy, protein-rich foods, olive oil, red and processed meat, sweets, salty snacks and spreadable fats, fermented alcoholic beverages and water. The same approach was followed to calculate the SENC hydration pyramid (HP) score, considering the intake of water and different kind of beverages. Adherence was calculated at baseline and after 10 years of follow-up. Cox proportional hazards models were used to assess the incidence of overweight/obesity (BMI >= 25 kg/m(2)). During a median follow-up of 10.3 years, 2320 incident cases were identified. The highest level of adherence to the SENC FP score was modestly associated with a reduced risk of overweight/obesity (multi variable-adjusted HR for the fifth quintile vs. the first quintile = 0.78; 95% CI: 0.67-0.91; p-trend: 0.007). No consistent trends were found for the SENC HP. In a large prospective cohort of Spanish university graduates, we found an inverse linear association between adherence to the SENC FP and overweight/obesity risk, whereas this was not the case for the HP.

The 2015-2020 Dietary Guidelines for Americans (DGA) was issued in early 2016. It remains untested if adherence to these guidelines could reduce mortality risk. Using a modified version of the 2015 Dietary Guidelines for American Index (2015 DGAI), we investigated if adherence to the new DGA is associated with mortality in a Spanish (the Seguimiento Universidad de Navarra, SUN) cohort. We assessed the habitual diet of 16,866 participants of this cohort recruited between 1999 and 2014 and calculated their adherence scores to the new DGA using the modified 2015 DGAI (0-21 points). Mortality data was determined from the yearly National Death Index reports. After adjusting for demographic and lifestyle confounders, high adherence scores (fourth quartile) were found to be associated with reduced all-cause, cardiovascular and cancer mortality risk, hazard ratios (HR) (95% confidence intervals [CI]) 0.42 (0.25-0.70), 0.30 (0.10-0.90) and 0.46 (0.22-0.96), respectively, compared to low adherence scores (first quartile). A 2-point increase in the 2015 DGAI score was linearly inversely associated with all-cause mortality (HR [95% CI] 0.78 [0.67-0.92]). Main sources of variability in the adherence scores were whole-fat dairy products, red/orange vegetables, fresh fruits, red meat, and dark green vegetables. In conclusion, higher adherence to 2015-2020 Dietary Guidelines for Americans was inversely associated with total, cardiovascular and cancer mortality risk in a Spanish cohort.

OBJECTIVE To evaluate the association between consumption of ultra-processed foods and all cause mortality. DESIGN Prospective cohort study. SETTING Seguimiento Universidad de Navarra (SUN) cohort of university graduates, Spain 1999-2018. PARTICIPANTS 19 899 participants (12 113 women and 7786 men) aged 20-91 years followed-up every two years between December 1999 and February 2014 for food and drink consumption, classified according to the degree of processing by the NOVA classification, and evaluated through a validated 136 item food frequency questionnaire. MAIN OUTCOME MEASURE Association between consumption of energy adjusted ultra-processed foods categorised into quarters (low, low-medium, medium-high, and high consumption) and all cause mortality, using multivariable Cox proportional hazard models. RESULTS 335 deaths occurred during 200 432 persons years of follow-up. Participants in the highest quarter (high consumption) of ultra-processed foods consumption had a higher hazard for all cause mortality compared with those in the lowest quarter (multivariable adjusted hazard ratio 1.62, 95% confidence interval 1.13 to 2.33) with a significant dose-response relation (P for linear trend=0.005). For each additional serving of ultra-processed foods, all cause mortality relatively increased by 18% (adjusted hazard ratio 1.18, 95% confidence interval 1.05 to 1.33). CONCLUSIONS A higher consumption of ultra-processed foods (>4 servings daily) was independently associated with a 62% relatively increased hazard for all cause mortality. For each additional serving of ultra-processed food, all cause mortality increased by 18%.

BACKGROUND AND AIMS:
A Mediterranean-type diet enriched with extra virgin olive oil has been associated with a reduction in the incidence of atrial fibrillation (AF) in a population at high cardiovascular risk. However, no study has replicated these findings. In our study, we analyzed the association between olive oil consumption and AF in the SUN project, a cohort with young Spanish adults at low cardiovascular risk.
METHODS AND RESULTS:
We included all participants without prevalent AF at baseline (18,118 participants). Incident AF cases were confirmed by a cardiologist following a prespecified protocol. We used multivariable repeated-measurement Cox models adjusted for possible confounders (sex, age, BMI, and several classic cardiovascular risk factors). After a mean follow-up of 10.1 years, 94 AF incident cases were confirmed. Comparing to the lowest category of consumption (<7.9 g/d), the multivariable models showed hazard ratios (IC 95%) of 1.52 (0.93-2.48) for low-to-moderate, 1.44 (0.83-2.47) for moderate-to-high and 1.27 (0.56-2.86) for high olive oil intake. In a subgroup analysis stratified by overweight, an inverse although non-significant association was found only among overweight participants when we compared the highest vs the lowest category of consumption (p for interaction = 0.043).
CONCLUSION:
No association between olive oil and AF was found in this low-risk cohort, although the effect of extra-virgin olive oil on AF prevention especially among people with overweight deserves further investigation.

Purpose We assessed the association of total meat, processed, and unprocessed red meat and iron intake with the risk of developing gestational diabetes mellitus (GDM) in pregnant women. Methods We conducted a prospective study among 3298 disease-free Spanish women participants of the SUN cohort who reported at least one pregnancy between December 1999 and March 2012. Meat consumption and iron intake were assessed at baseline through a validated, 136-item semi-quantitative, food frequency questionnaire. We categorized total, red, and processed meat consumption and iron intake into quartiles. Logistic regression models were used to adjust for potential confounders. Results We identified 172 incident cases of GDM. In the fully adjusted analysis, total meat consumption was significantly associated with a higher risk of GDM [OR = 1.67 (95% CI 1.06-2.63, p-trend 0.010)] for the highest versus the lowest quartile of consumption. The observed associations were particularly strong for red meat consumption [OR = 2.37 (95% CI 1.49-3.78, p-trend < 0.001)] and processed meat consumption [OR = 2.01 (95% CI 1.26-3.21, p-trend 0.003)]. Heme iron intake was also directly associated with GDM [OR = 2.21 (95% CI 1.37-3.58, p-trend 0.003)], although the association was attenuated and lost its statistical significance when we adjusted for red meat consumption [OR = 1.57 (95% CI 0.91-2.70, p-trend 0.213)]. No association was observed for non-heme and total iron intake, including supplements. Conclusions Our overall findings suggest that higher pre-pregnancy consumption of total meat, especially red and processed meat, and heme iron intake, are significantly associated with an increased GDM risk in a Mediterranean cohort of university graduates.

Introduction and objectives: Our aim was to prospectively evaluate the association between egg consumption and dyslipidemia in a Mediterranean cohort. Methods: We followed-up 13,104 Spanish university graduates for a mean period of 8 years. Dietary habits at baseline were assessed using a validated semi-quantitative 136-item food-frequency questionnaire. Self-reported blood concentrations of total cholesterol, high-density lipoproteins cholesterol (HDL-c) and triglycerides were evaluated according to categories of egg consumption after 6 and 8 years of follow-up. We also assessed the association between baseline egg consumption and the incidence of hypercholesterolemia, low HDL-c concentrations and hypertriglyceridemia during follow-up. Results: We observed a significant inverse association for intermediate levels of egg consumption (2 to 4 eggs/week vs. less than 1 egg/week) and hypertriglyceridemia with OR = 0.71 (95% confidence interval [CI]: 0.54 to 0.93, p < 0.05) in the multivariable-adjusted model. Using HDL-c values after 8-year follow-up, we found an association between higher egg consumption and lower HDL-c levels (p for trend = 0.02) with an adjusted difference of -4.01 mg/dl (-7.42 to -0.61) for > 4 vs. < 1 egg/week. Lower means of triglycerides were found in each of the three upper categories of egg consumption compared to the lowest category (< 1 egg/week) with significant results for some of these categories both after 6 and 8 year follow-up. Conclusions: Our data do not support that higher egg consumption was associated with abnormal blood levels of total cholesterol or triglycerides; an inverse association with HDL-c as a quantitative variable was found only in one of our analyses.

The Mediterranean Dietary (MedDiet) Pattern has been linked to many beneficial health effects. This review summarizes the main findings of a prospective cohort study, the Seguimiento Universidad de Navarra (SUN) cohort, specifically focused on MedDiet and the risk of major chronic disease. It is an open cohort in which 22,786 Spanish university graduates have participated since 1999 until February 2018. Data on diet, lifestyle and clinical diagnosis are collected at baseline and every two years. After reviewing 21 publications from the SUN cohort on the effects of the MedDiet, we conclude that this cohort has provided good evidence that a high MedDiet adherence is associated with a reduced incidence of all-cause mortality, fatal and non-fatal major cardiovascular disease (CVD), type 2 diabetes, weight gain, metabolic syndrome, depression, cognitive decline, and nephrolithiasis. An inverse dose-response relationship was found for many of these associations. The MedDiet was also associated with lower average heart rate, a mitigation of the harmful effects of overweight/obesity on the risk of CVD, and an attenuation of the effects of obesity on type 2 diabetes. A suggestion that the MedDiet may enhance fertility was also found.

Background: Diet plays an important role in the pathogenesis of nephrolithiasis. Limited data are available to investigate the association between a Mediterranean dietary pattern and risk for nephrolithiasis. Study Design: Prospective cohort study. Setting & Participants: 16,094 men and women without a history of nephrolithiasis who participated in the Seguimiento Universidad de Navarra Follow-up (SUN) Project. Predictors: A validated 136-item food frequency questionnaire was used to assess baseline adherence to a Mediterranean dietary pattern that is high in fruits, vegetables, nuts, fish, and legumes, but moderate in alcohol and low in meats, saturated fats, and sugars. A Mediterranean dietary pattern score was calculated and categorized into 3 groups (0-3, 4-6, and 7-9 points). Additional factors included in statistical models were sex, age, body mass index, smoking, physical activity, time spent watching television, following a medical nutritional therapy, water and energy intake, calcium and vitamin D supplementation, and history of hypertension or diabetes. Outcomes: Incidence of nephrolithiasis. Participants were classified as having incident nephrolithiasis if they reported a physician-made diagnosis of nephrolithiasis during follow-up. Results: After a mean follow-up of 9.6 years, 735 new cases of nephrolithiasis were identified. The multivariable HRs of nephrolithiasis for the 2 highest categories of adherence to the Mediterranean dietary pattern, using the lowest category as the reference, were 0.93 (95% CI, 0.79-1.09) and 0.64 (95% CI, 0.48-0.87); P for trend = 0.01. The risk for nephrolithiasis was lower with greater consumption of dairy products and vegetables and greater with higher monounsaturated fatty acid to saturated fatty acid ratio. Limitations: No information for kidney stone composition. Conclusions: Greater adherence to a Mediterranean dietary pattern was associated with reduced risk for incident nephrolithiasis. Additional longitudinal studies are needed. (C) 2017 by the National Kidney Foundation, Inc.

Nutritional adequacy implies sufficient intake of essential nutrients needed to [...]
Background The assessment of changes in dietary habits provides interesting information on whether or not the observed trends are in line with accepted nutritional guidelines. The objective was to evaluate within-subject longitudinal changes in food consumption and nutrient intake and in a 10-year follow-up study. Methods The SUN ( ) project is a prospective Spanish cohort study. Diet was assessed using a 136-item food-frequency questionnaire (FFQ), previously validated in Spain. The participants were 3036 university graduates (55.8 % women) of Spain and the main outcome measures the changes in dietary quality and in food consumption and nutrient intake. Paired t-tests and conditional logistic regression models were used to evaluate within-subject longitudinal dietary changes and the risk of inadequacy respectively, after 10 years of follow-up. Results During follow-up, participants showed a relevant and significant increase (p 0.001) in the consumption of fruits (7.4 %), vegetables (8.6 %), low-fat dairy products (35.2 %), lean meat (12.4 %), fish (2.9 %), whole grains (53.2 %), nuts (52.4 %) and a significant decrease in legumes (-7.4 %), whole-fat dairy products (-44.2 %), red meat (-17.6 %), sugar-sweetened beverages (-58.7 %) and wine (-11.9 %). With respect to nutrients, we found a higher proportion of carbohydrates (3.6 %) and fiber (7.4 %) and a decrease in total energy intake (2.7 %), total fat (-4.5 %), SFA (-9.4 %), MUFA (-4.9 %), PUFA (-12.7 %), w-3 and w-6 fatty acids (-9.1 and -20.5 % respectively) and cholesterol (-9.6 %). Conclusions In this Mediterranean cohort study, mainly beneficial changes in the consumption of most foods and macronutrients were observed after 10 years of follow-up.

Background/ Objectives: To evaluate the association between the carbohydrate quality (CQI) and weight change or incident overweight/obesity (BMI¿25 kg/m2) in the ¿Seguimiento Universidad de Navarra (SUN)¿ cohort. Subjects/ Methods: 8 741 participants initially free of overweight/obesity were followed¿up for a median of 7.9 years. We evaluated at baseline the CQI following 4 criteria: dietary fibre intake, glycemic index (GI), whole grains/total grains ratio and solid carbohydrates/total carbohydrates ratio. Subjects were classified into quintiles according to CQI. Weight was recorded at baseline and updated every 2 years during follow¿up. Results: Increasing CQI of diet was not significantly associated with lower weight gain, although participants in the highest quintile had the lowest average crude weight gain (+211 g/year). We observed 1 862 incident cases of overweight/obesity during followup. CQI was significantly associated (p for trend 0.006) with lower risk of overweight/obesity: adjusted OR for the 4rd and 5th quintiles: 0.81 (95% CI 0.66 to 0.99), and 0.74 (95% CI 0.60 to 0.92), respectively. Conclusions: In this Mediterranean cohort, CQI showed a significant inverse association with the incidence of overweight/obesity, which highlights that carbohydrate intake guidelines related to obesity prevention should be focused in improving the CQI of the diet.

Objetivo: Investigar la asociación entre la frecuencia de comidas fuera de casa (CFC) con a) la calidad de hidratos de carbono y b) la calidad de grasas. Materiales y métodos: Se evaluaron 19.371 participantes de la cohorte SUN que completaron un cuestionario basal de frecuencia de consumo de alimentos previamente validado. Se utilizaron los índices de calidad de hidratos de carbono (ICHC) en una escala de 4 a 20 y de grasas (ICG) en una escala de 0,62 a 5,92. En ambos casos, a mayor puntuación mayor calidad. Se utilizó la regresión lineal múltiple para determinar la asociación entre la frecuencia de CFC (4 categorías) y la puntuación de ambos índices, y la regresión logística para medir la asociación entre la frecuencia de CFC y un bajo ICHC o ICG (<percentil 25). Resultados: Los participantes mostraron una media de ICHC e ICG de 11,3 (DE 3,2) y 1,7 (DE 0,5), respectivamente. Una mayor frecuencia de CFC (¿ 2 veces / semana) se asoció con un menor ICHC (ß: -0,29, IC 95%: -0,41 a -0,17, p <0,001), y con un menor ICG (ß: -0,02, IC 95%: -0,03 a -0,001, p <0,03). Los participantes con CFC ¿ 2 veces/semana tuvieron mayor riesgo de peor ICHC (OR: 1,31, IC 95%: 1,17-1,46, p <0,001), pero no de peor ICG (OR: 0,93 IC 95%: 0,83-1,03, p 0,194). Conclusiones: Hacer con mayor frecuencia CFC se asoció con una peor calidad de grasas en la dieta y especialmente con peor calidad de hidratos de carbono. Estos resultados destacan la importancia de la educación nutricional dirigida a los consumidores de CFC.

Epidemiological research confirms that the prevalence of suboptimal micronutrient intakes across Europe is an emerging concern in terms of public health. The aim of the present study was to investigate the association between a new index of carbohydrate (CHO) quality and micronutrient intake adequacy in the `Seguimiento Universidad de Navarra (SUN)¿ cohort. The baseline assessment extended from 1999 to March 2012. We assessed 16 841 participants who completed a validated 136-item semi-quantitative FFQ at baseline. We created a new index to evaluate CHO quality for the following four criteria: dietary fibre intake; glycaemic index; whole grains:total grains ratio; solid CHO:total CHO ratio. The subjects were classified into quintiles according to this index. We evaluated the intakes of Zn, I, Se, Fe, Ca, K, P, Mg, Cr and vitamins B1, B2, B3, B6, B12, C, A, D, E and folic acid. The probability of intake adequacy was evaluated using the estimated average requirement cut-point approach and the probabilistic approach. Logistic regression analysis was used to assess the nutritional adequacy according to the CHO quality index (CQI). Participants in the highest quintile of CQI were found to have the lowest prevalence of inadequacy. A higher quality of CHO intake was found to be associated with a lower risk of nutritional inadequacy in comparison with the lowest quintile of CQI (adjusted OR 0·06, 95 % CI 0·02, 0·16; P for trend < 0·001). A higher CQI was found to be strongly associated with better micronutrient intake adequacy in the young Mediterranean cohort, stressing the importance of focusing nutritional education not only on CHO quantity, but also on quality.

Background
To evaluate prospectively the relationship between white, or whole grain bread, and glycemic index, or glycemic load from diet and weight change in a Mediterranean cohort.
Methods
We followed-up 9 267 Spanish university graduates for a mean period of 5 years. Dietary habits at baseline were assessed using a semi-quantitative 136-item food-frequency questionnaire. Average yearly weight change was evaluated according to quintiles of baseline glycemic index, glycemic load, and categories of bread consumption. We also assessed the association between bread consumption, glycemic index, or glycemic load, and the incidence of overweight/obesity.
Results
White bread and whole-grain bread were not associated with higher weight gain. No association between glycemic index, glycemic load and weight change was found. White bread consumption was directly associated with a higher risk of becoming overweight/obese (adjusted OR (¿2 portions/day) versus (¿1 portion/week): 1.40; 95% CI: 1.08-1.81; p for trend: 0.008). However, no statistically significant association was observed between whole-grain bread, glycemic index or glycemic load and overweight/obesity.
Conclusions
Consumption of white bread (¿2 portions/day) showed a significant direct association with the risk of becoming overweight/obese.

Objective: The aim of this study was to assess the association between nut consumption and all-cause mortality after 5-y follow-up in a Spanish cohort. Methods: The SUN (Seguimiento Universidad de Navarra, University of Navarra Follow-up) project is a prospective cohort study, formed by Spanish university graduates. Information is gathered by mailed questionnaires collected biennially. In all, 17 184 participants were followed for up to 5 y. Baseline nut consumption was collected by self-reported data, using a validated 136-item semi-quantitative food frequency questionnaire. Information on mortality was collected by permanent contact with the SUN participants and their families, postal authorities, and the National Death Index. The association between baseline nut consumption and all-cause mortality was assessed using Cox proportional hazards models to adjust for potential confounding. Baseline nut consumption was categorized in two ways. In a first analysis energy-adjusted quintiles of nut consumption (measured in g/d) were used. To adjust for total energy intake the residuals method was used. In a second analysis, participants were categorized into four groups according to pre-established categories of nut consumption (servings/d or servings/wk). Both analyses were adjusted for potential confounding factors. Results: Participants who consumed nuts ¿2/wk had a 56% lower risk for all-cause mortality than those who never or almost never consumed nuts (adjusted hazard ratio, 0.44; 95% confidence intervals, 0.23-0.86). Conclusion: Nut consumption was significantly associated with a reduced risk for all-cause mortality after the first 5 y of follow-up in the SUN project.

Background and aims: The consumption of fried foods is believed to be linked with obesity and higher weight gain, however, the evidence from long-term randomized trials or prospective epidemiological studies is scarce. Therefore, the aim of our study was to prospectively evaluate the association between the consumption of fried foods and weight change and the incidence of overweight/obesity in a Mediterranean cohort.
Methods and results: Prospective cohort study of 9850 men and women with a mean age of 38.1 years (SD 11.4) were followed-up for a median of 6.1 years to assess average yearly change in body weight, and incidence of overweight/obesity. The consumption of fried foods was associated with higher weight gain, but the differences were of small magnitude and statistically non-significant. The incidence of overweight/obesity during follow-up was also assessed in the subset of 6821 participants with initial body mass index <25 kg/m(2) (initially free of overweight/obesity), after adjusting for potential confounders, the odds ratio for developing overweight/obesity among participants who consumed fried foods >4 times/week was 1.37 (95% confidence interval: 1.08 to 1.73) in comparison with those who consumed fried foods <2 times/week (p for trend = 0.02).
Conclusion: In this Mediterranean prospective cohort, a more frequent consumption of fried foods at baseline was associated with a higher risk of subsequently developing overweight/obesity during follow-up.

Objective To assess the long-term relationship between tree nut consumption and the risk of developing metabolic syndrome (MetS).
Design Nut consumption was collected using a validated 136-item FFQ. The MetS was defined according to the International Diabetes Federation and American Heart Association/National Heart, Lung, and Blood Institute harmonizing definition. The association between nut consumption and MetS was assessed with logistic regression models adjusting for potential confounders. We compared the incidence of MetS between extreme categories of nut intake (¿2 servings/week v. never/almost never) after 6 years of follow-up.
Setting The SUN Project (Seguimiento Universidad de Navarra, University of Navarra Follow-up) is a prospective cohort study, formed of Spanish university graduates. Information is gathered by mailed questionnaires collected biennially. Nut consumption and MetS information was collected by self-reported data.
Subjects Participants (n 9887) initially free of MetS or diabetes and followed up for a minimum of 6 years were included.
Results We observed 567 new cases of MetS during follow-up. Participants who consumed nuts ¿2 servings/week presented a 32 % lower risk of developing MetS than those who never/almost never consumed (adjusted OR = 0·68, 95 % CI 0·50, 0·92). The inverse association was stronger among participants who were health professionals.
Conclusions Nut consumption was significantly associated with lower risk of developing MetS after a 6-year follow-up period in a cohort of Spanish graduates.

Background & aims: We investigated whether protein intake (PI) is related to osteoporotic fractures (OP) in the elderly by analyzing vegetable protein intake (VPI), animal protein intake (API), and animal/vegetable protein intake ratio (AVR) and by calcium intake (CaI).
Methods: A 1:1 matched by age and sex case control study with 167 cases was carried out at the Hospital of Jaen (Spain). Cases were patients aged >= 65 years with a low-energy fracture. Controls were people without previous fractures. Diet was assessed by a food frequency questionnaire. Multivariable analyses were fitted using analysis of covariance (for comparison of adjusted means) and conditional logistic regression (estimating adjusted odds ratios [ORs]).
Results: The control-group showed a higher API (p = 0.046) even when CaI was <800 mg/day (p = 0.041). ORs for AVR were 0.68 (0.38-1.19) and 0.38 (0.15-0.98), respectively with a p for trend = 0.046. A PI<15% of the total energy intake showed an OR of 2.86 (1.10-7.43).
Conclusions: Patients with fracture history have lower API suggesting that high API reduce the occurrence of OP in elderly even if CaI is <800 mg/day. A PI<15% of total calories were associated with an increased risk of OP in elderly.

BACKGROUND/OBJECTIVES:
Egg consumption has been associated with the risk of cardiovascular diseases (CVDs), but evidence is scarce and inconsistent. Our aim was to examine the association between egg consumption and incidence of CVD in a prospective dynamic Mediterranean cohort of 14,185 university graduates.
SUBJECTS/METHODS:
Egg intake was assessed using a 136-item-validated food-frequency questionnaire. Baseline consumption was categorized into no consumption or <1 egg/week, 1 egg/week, 2-4 eggs/week and >4 eggs/week. The presence of cardiovascular risk factors was assessed by questionnaire at baseline, and the incidence of CVD was assessed using biennial assessments. The median follow-up was 6.1 years. Cox regression models were fitted to estimate multivariable-adjusted hazard ratios (HRs) for CVD (myocardial infarction, revascularization procedures or stroke). Outcomes were confirmed by review of medical records.
RESULTS:
During a median follow-up of 6.1 years, 91 new confirmed cases of CVD were observed. No association was found between egg consumption and the incidence of CVD (HR: 1.10, 95% confidence interval: 0.46-2.63) for the highest versus the lowest category of egg consumption after adjusting for age, sex, total energy intake, adherence to the Mediterranean food pattern and other cardiovascular risk factors. Results were robust to different analytical scenarios.
CONCLUSIONS:
No association between egg consumption and the incidence of CVD was found in this Mediterranean cohort.

Objetivos
Valorar la validez de los datos autodeclarados sobre los criterios de síndrome metabólico, en la cohorte SUN (Seguimiento Universidad de Navarra).
Métodos
El proyecto SUN es una cohorte abierta multidisciplinaria formada por más de 20.000 graduados universitarios seguidos mediante cuestionarios enviados por correo cada 2 años. En una muestra de 287 participantes de la cohorte se valoró el acuerdo entre sus datos autodeclarados para el perímetro de la cintura, la presión arterial, los triglicéridos, el colesterol HDL y la glucemia, con los datos obtenidos por análisis de muestras biológicas o medidos por personal médico especializado. Para cada variable se calcularon coeficientes de correlación intraclase (CCI) con intervalos de confianza del 95% (IC95%), el error relativo medio y el porcentaje de valores dentro de los límites de acuerdo al 95% según el método de Altman y Bland.
Resultados
Se encontraron correlaciones intraclase altas para los valores del perímetro de la cintura (CCI = 0,86, IC95%: 0,80-0,90) y la trigliceridemia (CCI = 0,71, IC95%: 0,61-0,79). Se halló una consistencia moderada (CCI entre 0,46 y 0,63) para el resto de los factores que se usan como criterios para definir el síndrome metabólico. Los errores relativos medios nunca superaron el 2,5%, y el porcentaje de valores dentro de los límites de acuerdo superó en todos los casos el 91%.
Conclusiones
Los resultados obtenidos sugieren que los valores autodeclarados sobre los criterios del síndrome metabólico obtenidos en la cohorte SUN poseen una validez moderada y pueden tenerse en cuenta, aunque con ciertas precauciones, en estudios epidemiológicos.
