Health-related quality of life in individuals with metabolic syndrome: A cross-sectional study.

INTRODUCTION AND OBJECTIVES: Metabolic syndrome (MetS) is a combination of various cardiovascular risk factors with a major impact on morbidity and premature mortality. However, the impact of MetS on self-reported health-related quality of life (HRQoL) is unknown. This study evaluated the HRQoL in a Spanish adult population aged 55 years and older with MetS. METHOD: A cross-sectional analysis was performed with baseline data from the PREDIMED-Plus multicentre randomized trial. The participants were 6430 men and women aged 55-75 years with overweight/obesity (body mass index ≥27 and ≤40kg/m2) and MetS. The SF-36 questionnaire was used as a tool to measure HRQoL. Scores were calculated on each scale of the SF-36 by gender and age. RESULTS: Participants showed higher scores in the social function (mean 85.9, 95% CI; 85.4-86.4) and emotional role scales (mean 86.8, 95% CI; 86.0-87.5). By contrast, the worst scores were obtained in the aggregated physical dimensions. In addition, men obtained higher scores than women on all scales. Among men, the worst score was obtained in general health (mean 65.6, 95% CI; 65.0-66.2), and among women, in body pain (mean 54.3, 95%CI; 53.4-55.2). A significant decrease was found in the aggregated physical dimensions score among participants 70-75 years old, but an increased one in the aggregated mental dimensions, compared to younger participants. CONCLUSIONS: Our results reflect that the MetS may negatively affect HRQoL in the aggregated physical dimensions, body pain in women, and general health in men. However, this adverse association was absent for the psychological dimensions of HRQoL, which were less affected.

Coffee consumption and mortality from all causes of death, cardiovascular disease and cancer in an elderly Spanish population.

PURPOSE: The effect of coffee consumption on mortality has been scarcely investigated in the elderly. We assessed the association between coffee consumption and mortality from all-cause, cardiovascular disease (CVD) and cancer, in an elderly population of Spain. METHODS: We studied 903 individuals (511 women) aged 65 years and older from two population-based studies, the EUREYE-Spain study and the Valencia Nutritional Survey. Coffee consumption and diet were assessed using a validated food frequency questionnaire. Information on education, anthropometry, sleeping time, smoking, alcohol intake, physical activity and pre-existing disease was collected at baseline. Deaths were ascertained during a 12-year follow-up period, and Cox proportional hazards regression models were used to estimate adjusted hazard ratios (HR). RESULTS: There were 403 deaths during the 12-year period (40% from CVD), 174 of which occurred during the first 6 years. We observed evidence of a lower CVD mortality among coffee drinkers in the first 6 years of follow-up. Drinkers of ≤1 cup of coffee/day and > 1 cup/day showed lower CVD mortality than non-drinkers of coffee, HR 0.82 (95% CI 0.46-1.44) and HR 0.38 (0.15-0.96), respectively (p trend = 0.04). This association of coffee with CVD mortality attenuated after 12 years of follow-up. No significant association was observed with all-cause or cancer mortality, neither for caffeinated and decaffeinated coffee. CONCLUSIONS: In this study, coffee consumption was associated with lower CVD mortality in elderly. Although this association should be further investigated, coffee consumption appears to be safe for the elderly since no increased mortality was observed in coffee drinkers.

Mediterranean dietary pattern in pregnant women and offspring risk of overweight and abdominal obesity in early childhood: the INMA birth cohort study.

BACKGROUND: Animal models have suggested that maternal diet quality may reduce offspring obesity risk regardless of maternal body weight; however, evidence from human studies is scarce. OBJECTIVE: The aim of this study was to evaluate associations between adherence to the Mediterranean diet (MD) during pregnancy and childhood overweight and abdominal obesity risk at 4 years of age. METHODS: We analysed 1827 mother-child pairs from the Spanish 'Infancia y Medio Ambiente' cohort study, recruited between 2003 and 2008. Diet was assessed during pregnancy using a food frequency questionnaire and MD adherence by the relative Mediterranean diet score (rMED). Overweight (including obesity) was defined as an age-specific and sex-specific body mass index ≥85th percentile (World Health Organization referent), and abdominal obesity as a waist circumference (WC) >90th percentile. Multivariate adjusted linear and logistic regression models were used to evaluate associations between pregnancy rMED and offspring overweight and abdominal obesity. RESULT: There was no association between rMED and body mass index z-score, whereas there was a significant association between higher adherence to MD and lower WC (ß of high vs. low rMED: -0.62 cm; 95% confidence interval: -1.10, -0.14 cm, P for trend = 0.009). CONCLUSION: Pregnancy adherence to the MD was not associated with childhood overweight risk, but it was associated with lower WC, a marker of abdominal obesity.
