Background: Telomere length (TL) is a marker of biological age that may be affected by dietary factors through oxidation and inflammation mechanisms. In addition, ultra-processed food (UPF) consumption has increasedworldwide and it has been associated with the risk of developing several diseases. Objectives: We aimed to evaluate the association between UPF consumption and the risk of having short telomeres in an elderly population of the Seguimiento Universidad de Navarra (SUN) Project. Methods: This is a cross-sectional study of 886 participants (645 men and 241 women) aged 57-91 y recruited from the SUN Project (Spain, 1999-2018). TL was measured from saliva samples by real-time qPCR at baseline and UPF consumption was collected using a validated 136-item FFQ and classified according to the NOVA system. We evaluated the association between consumption of energy-adjusted UPF categorized into quartiles (low, medium-low, medium-high, and high consumption) and the risk of having short telomeres (<20th percentile) using logistic regression models. Results: Those participants with the highest UPF consumption had almost twice the odds of having short telomeres compared with those with the lowest consumption (adjusted OR: 1.82; 95% CI: 1.05, 3.22; P-trend = 0.03). Conclusions: A higher consumption of UPF (>3 servings/d) was associated with higher risk of having shorter telomeres in an elderly Spanish population of the SUN Project.

Weight gain is an adverse effect of antidepressants and antipsychotics. This side effect can lead to numerous comorbidities and reduces life expectancy. The use of these drugs is increasing worldwide, and the weight gain produced by them represents a common clinical challenge. The goal of this systematic review was to evaluate the potential association of antidepressant and antipsychotic therapy with body weight gain in cohort studies. A search of cohort studies investigating the association between weight gain and the use of antidepressants and antipsychotics in individuals was conducted through the PubMed database from 1 January 2008 to 31 January 2019 following the PRISMA statement. We found 27 independent eligible cohort studies that included children (2-18 years old) and adult (18-103 years old) subjects. Most of the included studies showed a 5% weight gain in individuals using antidepressant therapy. However, Quetiapine, Haloperidol, Trifluoperazine, Risperidone, Aripiprazole, Olanzapine, and Clozapine increased body weight >= 7% from baseline, which is considered a clinically significant result. Weight loss was found in individuals treated with Bupropion. Further cohort studies with higher sample sizes and longer durations of treatment are needed to confirm our observations.
