The association of dietary energy density (ED) and overweight is not clear in the literature. Our aim was to study in 4259 of the PREDIMED trial whether an increase in dietary ED based on a higher adherence to a Mediterranean dietary pattern was associated with 3-year weight gain. A validated 137-item food-frequency questionnaire was administered. Multivariable-adjusted models were used to analyze the association between 3-year ED change and the subsequent 3-year body weight change. The most important weight reduction after 3-year follow-up was observed in the two lowest quintiles and the highest quintile of ED change. The highest ED increase was characterized by an increased intake of extra virgin olive oil (EVOO) and nuts and a decreased intake of other oils, vegetable and fruit consumption (p < .001). In conclusion, increased 3-year ED in the PREDIMED study, associated with a higher EVOO and nuts consumption, was not associated with weight gain. ; The PREDIMED trial was supported by the Instituto de Salud Carlos III (ISCIII), the official funding agency for Biomedical Research of the Spanish Government, through grants provided to research networks specifically developed for the trial: RTIC G03/140, CIBERobn and RTIC RD06/0045.

OBJECTIVES: Dietary patterns may have a greater influence on human health than individual foods or nutrients and they are also being widely studied in the field of breast cancer prevention. Beyond the adequate balance of macronutrients, evidence shows that the quality of fat sources may play an important role in health outcomes. Our aim was to assess the relationship between healthful and less healthful low-fat dietary patterns in relation to breast cancer in a Mediterranean cohort (the SUN project). METHODS: The SUN Project is a Mediterranean dynamic prospective follow-up cohort study assessing participants every 2 years. We evaluated 10,930 middle-aged women initially free of breast cancer during a median of follow-up of 12.1 years. Dietary variables were evaluated through a previously validated 136-item FFQ. We calculated an overall, an unhealthful, and a healthful low-fat-diet score (rang: 0–30 points) based on the percentage of energy from total and subtypes of carbohydrate, fat, and protein. Participants were then categorized into tertiles. Incident breast cancer was de primary outcome. We fitted Cox regression models adjusted for potential confounders to investigate the relationship between baseline categories of low-fat-diet scores and the incidence of breast cancer- overall and stratified by menopausal status-. RESULTS: During 123,297 person-years of follow-up, 119 cases of incident breast cancer were confirmed. Among postmenopausal women, a significant direct association with postmenopausal breast cancer (comparing tertile 2 vs. tertile 1, HR = 2.60; 95% CI 1.24–5.45, P value = 0.012) was found. None of the other associations was statistically significant. CONCLUSIONS: In this Mediterranean prospective cohort study, a moderate adherence to an unhealthy low-fat-diet-score might increase the risk of postmenopausal breast cancer. These results must be further confirmed in future studies. FUNDING SOURCES: The SUN project received funding from the Spanish Government-Instituto de Salud Carlos III, and the ...

OBJECTIVE: Due to the growing interest in the role of dietary patterns (DPs) on chronic diseases, we assessed the association between a posteriori identified DPs in the Seguimiento Universidad de Navarra (SUN) Project - a prospective cohort study in a Mediterranean country - and breast cancer (BC) risk. DESIGN: DPs were ascertained through a principal component analysis based on 31 predefined food groups. BC cases were initially identified through self-report or, if deceased, from death certificates or by notification by the next kin. Women reporting BC were asked to provide a copy of their medical report and diagnoses for confirmation purposes. We fitted Cox regression models to assess the association between adherence to the identified DPs and BC risk. SETTING: Spanish university graduates. PARTICIPANTS: We included 10 713 young and middle-aged - mainly premenopausal - women. RESULTS: After a median follow-up of 10·3 years, we identified 100 confirmed and 168 probable incident BC cases. We described two major DPs: 'Western dietary pattern' (WDP) and 'Mediterranean dietary pattern' (MDP). A higher adherence to a WDP was associated with an increased risk of overall BC (multivariable-adjusted HR for confirmed BC Q4 v. Q1 1·70; 95 % CI 0·93, 3·12; P for trend = 0·045). Contrarily, adherence to a MDP was inversely associated with premenopausal BC (multivariable-adjusted HR Q4 v. Q1 0·33; 95 % CI 0·12, 0·91). No significant associations were observed for postmenopausal BC. CONCLUSIONS: Whereas a higher adherence to the WDP may increase the risk of BC, a higher adherence to the MDP may decrease the risk of premenopausal BC. ; The study was supported by the "Acción Transversal del Cáncer", approved on the Spanish Ministry Council on the 11th October 2007, by the Consortium for Biomedical Research in Epidemiology and Public Health (CIBERESP), by the Instituto de Salud Carlos III grants, cofunded by FEDER funds -a way to build Europe- PI08/1770 (to M.

Purpose. Wine consumption has been related to a reduced cardiovascular risk. This effect has been attributed partly to the healthier diet of wine drinkers. We compared food habits according to alcoholic beverage preference in a Mediterranean population. Design. A cross-sectional study of a large sample of participants at high risk for cardiovascular disease. Setting. Primary care centers in a Mediterranean country, Spain. Participants. A total of 1675 men aged 55 to 80 years old and 2150 women aged 60 to 80 years old who had no documented cardiovascular disease but had either diabetes or at least three major cardiovascular risk factors. Measures. A food frequency questionnaire, alcoholic beverage consumption, adherence to Mediterranean diet, age, family history of cardiovascular disease, smoking, body mass index, diabetes, dyslipidemia, and educational level were measured. Analysis. We analyzed differences in food consumption according to the type of alcoholic beverage preferentially consumed and adjusted the estimates for age, body mass index, cholesterol level, and total energy intake. Results. We found no substantial differences in adherence to the Mediterranean diet according to the main type of alcoholic beverage consumed, and we found no evidence that Mediterranean wine drinkers at high cardiovascular risk have a healthier diet than other drinkers. However, a better dietary pattern was found among nondrinkers than among drinkers. Conclusion. This large, Mediterranean study does not support an association between wine consumption and healthier dietary habits.

Limited data exists on the interrelationships between physical activity (PA), sedentary behaviors and sleep concerning cardiometabolic risk factors in aged adults at high cardiovascular disease risk. Our aim was to examine independent and joint associations between time spent in leisure-time PA, sedentary behaviors and sleep on the prevalence of obesity, type 2 diabetes (T2D) and components of the metabolic syndrome (MetS) in Mediterranean individuals at high cardiovascular risk. Cross-sectional analyses were performed on baseline data from 5776 Spanish adults (aged 55-75y in men; 60-75y in women) with overweight/obesity and MetS, from October 2013 to October 2016, in the PREDIMED-PLUS trial. Employing multivariable-adjusted Cox regression with robust variance and constant time (given the cross-sectional design), higher prevalence of obesity, T2D and abdominal obesity as component of the MetS were associated with greater time in TV-viewing (Relative Risk, RR: 1.02, 95%CI: 1.01, 1.03; RR:1.04, 95%CI: 1.02, 1.06 and RR: 1.01 95%CI: 1.00, 1.02; respectively, all P < .01). Conversely, greater time in moderate-vigorous PA (MVPA) was associated with lower prevalence of obesity, T2D, abdominal obesity and low HDL-cholesterol (RR: 0.95, 95%CI: 0.93, 0.97; RR: 0.94, 95%CI: 0.89, 0.99; RR: 0.97, 95%CI: 0.96, 0.98; and RR: 0.95, 95%CI: 0.91, 0.99, respectively, all P < .05). For these outcomes, theoretically substituting 1-h/day of MVPA for 1-h/day TV-viewing was also significantly associated with lower prevalence (RR 0.91 to 0.97, all P < .05). Similar lower RR in these outcomes was observed when substituting 1-h/day of MVPA for 1-h/day of sleeping. Longer time watching TV and not meeting MVPA recommendations were jointly associated with higher RR of the prevalence of obesity and T2D. We concluded that, in senior individuals at high cardiovascular risk, greater time spent on MVPA and fewer on sedentary behaviors was inversely associated with prevalence of obesity, T2D, and some of the components of MetS. ; This study was funded by the Spanish Ministry of Health (Carlos III Health Institute) through the Fondo de Investigacion para la Salud (FIS), which is co-funded by the European Regional Development Fund (two coordinated FIS projects leaded by Jordi Salas-Salvado and Josep Vidal, including the following projects: PI13/00673, PI13/00492, PI13/00272, PI13/01123, PI13/00462, PI13/00233, PI13/02184, PI13/00728 PI13/01090 PI13/01056, PI14/01722, PI14/00636, PI14/00618, PI14- 00696, PI14/01206, PI14/01919, PI14/00853), the European Research Council (Advanced Research Grant 2013-2018; 340918) granted to MAMG, the Recercaixa grant 2013 (2013ACUP00194), the grant from the Consejeria de Salud de la Junta de Andalucia (PI0458/2013), and the SEMERGEN grant.
