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.

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.

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.

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.

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.

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.

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.

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 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 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.

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.

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.
