    Abstract:
    Background & aims: Short telomeres have been observed in chronic disease patients. Identifying environmental and lifestyle factors that could reduce telomere attrition is crucial for disease prevention. The aim of this work was to determine whether weight-loss induced by an energy-reduced Mediterranean diet (erMedDiet) and physical activity (PA) could modify telomere length (TL). Methods: In 317 randomized non-smoker participants (mean age, 65.8 ± 4.98 years) with metabolic syndrome from two “Prevención con Dieta Mediterránea-Plus” (PREDIMED-Plus) trial centers, we evaluated MedDiet adherence, PA, anthropometric variables and TL at baseline and after a 3-year intervention using an intensive lifestyle program (IG) with an erMedDiet and PA or an unrestricted MedDiet without PA promotion (CG). Results: Participants in the IG displayed greater 3-year weight reductions (−3.7 ± 4 kg, P < 0.001) compared to those in the CG. No differences in TL changes between groups were observed in the cohort as a whole. However, an interaction was observed between the intervention group and sex for TL changes (pinteraction = 0.039). Women in the IG showed an increase in TL after 3-y (+0.25 ± 0.9, relative units) compared to women in the CG (−0.07 ± 1.0) (pANCOVA = 0.036), whereas no differences between groups were observed in men. Women in the IG had a lower risk of telomere shortening after the intervention (OR = 0.17, 95%CI: 0.05–0.64, p = 0.008) compared to women in the CG. Conclusions: A 3-year lifestyle intervention based on an erMedDiet and PA slowed telomere shortening in women but not in men. Trial registration: ISRCTN, ISRCTN89898870.
