BackgroundEvidence on the relation between leisure-time physical activity (LTPA) and health-related quality of life (HRQoL) in older adults is based primarily on clinical trials of physical exercise programs in institutionalized persons and on cross-sectional studies of community-dwelling persons. Moreover, there is no evidence on whether leisure-time sedentary behavior (LTSB) is associated with HRQoL independently of LTPA. This study examined the longitudinal association between LTPA, LTSB, and HRQoL in older community-dwelling adults in Spain.MethodsProspective cohort study of 1,097 persons aged 62 and over. In 2003 LTPA in MET-hr/week was measured with a validated questionnaire, and LTSB was estimated by the number of sitting hours per week. In 2009 HRQoL was measured with the SF-36 questionnaire. Analyses were done with linear regression and adjusted for the main confounders.ResultsCompared with those who did no LTPA, subjects in the upper quartile of LTPA had better scores on the SF-36 scales of physical functioning (β 5.65; 95% confidence interval [CI] 1.32-9.98; p linear trend < 0.001), physical role (β 7.38; 95% CI 0.16-14.93; p linear trend < 0.001), bodily pain (β 6.92; 95% CI 1.86-11.98; p linear trend < 0.01), vitality (β 5.09; 95% CI 0.76-9.41; p linear trend < 0.004) social functioning (β 7.83; 95% CI 2.89-12.75; p linear trend < 0.001), emotional role (β 8.59; 95% CI 1.97-15.21; p linear trend < 0.02) and mental health (β 4.20; 95% CI 0.26-8.13; p linear trend < 0.06). As suggested by previous work in this field, these associations were clinically relevant because the β regression coefficients were higher than 3 points. Finally, the number of sitting hours showed a gradual and inverse relation with the scores on most of the SF-36 scales, which was also clinically relevant.ConclusionsGreater LTPA and less LTSB were independently associated with better long-term HRQoL in older adults.

This is the first study to report the prevalence of general obesity and abdominal obesity (AO) in the adult population of Spain based on measurements of weight, height and waist circumference. The data are taken from the ENRICA study, a cross-sectional study carried out between June 2008 and October 2010 in 12,883 individuals representative of the non-institutionalized population on Spain aged 18 years and older. Anthropometry was performed under standardized conditions in the households by trained interviewers. Overweight was considered as body mass index (BMI) 25-29.9 kg m(-2) , and obesity as BMI ≥ 30 kg m(-2) . AO was defined as waist circumference >102 cm in men and >88 cm in women. The prevalence of obesity was 22.9% (24.4% in men and 21.4% in women). About 36% of adults had AO (32% of men and 39% of women). The frequency of obesity and of AO increased with age and affected, respectively, 35 and 62% of persons aged 65 and over. The frequency of obesity and AO decreased with increasing educational level. For example, 29% of women with primary education or less had obesity vs. only 11% of those with university studies. The prevalence of obesity was very high in the Canary Islands and in the south of Spain.

Objective: To assess the prospective association between ultra-processed food consumption and allcause mortality and to examine the effect of theoretical iso-caloric non-processed foods substitution. Patients and Methods: A population-based cohort of 11,898 individuals (mean age 46.9 years, and 50.5% women) were selected from the ENRICA study, a representative sample of the noninstitutionalized Spanish population. Dietary information was collected by a validated computer-based dietary history and categorized according to their degree of processing using NOVA classification. Total mortality was obtained from the National Death Index. Follow-up lasted from baseline (2008)(2009)(2010) to mortality date or December 31 th , 2016, whichever was first. The association between quartiles of consumption of ultra-processed food and mortality was analyzed by Cox models adjusted for the main confounders. Restricted cubic-splines were used to assess dose-response relationships when using iso-caloric substitutions. Results: Average consumption of ultra-processed food was 385 g/d (24.4% of the total energy intake). After a mean follow-up of 7.7 years (93,599 person-years), 440 deaths occurred. The hazard ratio (and 95% CI) for mortality in the highest versus the lowest quartile of ultra-processed food consumption was 1.44 (95% CI, 1.01-2.07; P trend¼.03) in percent of energy and 1.46 (95% CI, 1.04-2.05; P trend¼.03) in grams per day per kilogram. Isocaloric substitution of ultra-processed food with unprocessed or minimally processed foods was associated with a significant nonlinear decrease in mortality. Conclusion: A higher consumption of ultra-processed food was associated with higher mortality in the general population. Furthermore, the theoretical iso-caloric substitution ultra-processed food by unprocessed or minimally processed foods would suppose a reduction of the mortality risk. If confirmed, these findings support the necessity of the development of new nutritional policies and guides at the national and international level.

SUMMAR Y The few studies that have examined the association between usual sleep duration and cognitive function have shown conflicting results. This cross-sectional study examined the association between sleep duration and cognitive function among 3212 people, representative of the non-institutionalized population aged 60 years and over in Spain.Sleep duration was self-reported, and cognitive function was measured with the MiniExamen Cognoscitivo (MEC), a version of the Mini-Mental State Examination that has been validated in Spain. Linear regression, with adjustment for the main confounders, was used to obtain mean differences in the MEC between the categories of sleep duration (£5, 6, 7, 8, 9, 10, ‡11 h day )1 ). The MEC score decreased progressively (became worse) across sleep categories from 7 to ‡11 h (P for linear trend <0.001).People who slept for ‡11 h had a significantly lower MEC score than those who slept for 7 h (mean difference )1.48; 95% confidence interval )2.12 to )0.85). This difference in the MEC was similar to that observed for a 10-year increase in age. The results did not vary significantly by sex (P for interaction >0.05). No association was observed between short sleep duration (<7 h) and cognitive function. We conclude that long sleep duration is associated with poorer cognitive function in older adults from the general population.k e y w o r d s cognitive function, elderly people, sleep, spain

This work examined the Spanish population's degree of accordance with the Mediterranean diet (MD). This was a cross-sectional study conducted in 2008-2010 among 11,742 individuals representative of the Spanish population aged ≥ 18 y. Habitual food consumption was assessed with a computerized diet history. Accordance of food consumption with the MD was assessed with the MD Adherence Screener (MEDAS) score using the cutoffs ≥ 9 to define strict accordance and ≥ 7 (mid-range value) for modest accordance. Accordance of nutrient intake with the MD was defined as ≥ 4.5 points (mid-range value) on the high-unsaturated fat OmniHeart diet score. The diet of 12% (95% CI: 11.3-12.7%) of the Spanish population reached MEDAS-based strict accordance with the MD and 46% (95% CI: 44.7-47.7) attained modest accordance. Moreover, 39.0% (95%: 37.8-40.1%) of the population achieved OnmiHeart-based MD accordance. Factor analysis identified 2 main dietary patterns. The first one was called "Westernized" and was rich in red and processed meat, French fries, refined cereals, and sweetened beverages and poor in fresh fruit; the second pattern was named "Mediterranean" and was rich in olive oil and plant-based foods. Regardless of how it was defined, MD accordance was less frequent and the Westernized pattern was more frequent among the younger, the less educated, current smokers, and those less physically active and more sedentary. In conclusion, the Spanish population is drifting away from the MD to adopt a less healthy diet, typical of Western countries. The departure from the MD mostly affects the socially disadvantaged and clusters with other unhealthy lifestyles, which may have synergistic undesirable effects on health.

GUTIÉ RREZ-FISAC, JUAN L., ESTHER LÓ PEZ, JOSE R. BANEGAS, AUXILIADORA GRACIANI, AND FERNANDO RODRÍGUEZ-ARTALEJO. Prevalence of overweight and obesity in elderly people in Spain. Obes Res. 2004;12:710 -715. Objective: To estimate the prevalence of obesity and overweight in the older adult population in Spain by sex, age, and educational level. Research Methods and Procedures:A cross-sectional study was carried out in 2001 in a sample of 4009 persons representative of the noninstitutionalized population Ն60 years of age. Anthropometric measurements (BMI and waist circumference) were obtained using standardized techniques and equipment. Overweight was considered at a BMI of 25 to 29.9 kg/m 2 and obesity at a BMI of Ն30 kg/m 2 . Central obesity was considered at a waist circumference of Ͼ102 cm in men and Ͼ88 cm in women. Results: The mean BMI was 28.2 kg/m 2 in men and 29.3 kg/m 2 in women. The prevalence of overweight and obesity in men was 49% and 31.5%, respectively. The corresponding percentages in women were 39.8% and 40.8%. The prevalence of obesity was higher in persons with no education than in those with third level education (i.e., university studies), especially among women (41.8% vs. 17.5%). The prevalence of central obesity was 48.4% in men and 78.4% in women. Differences by educational level were seen in only women, in whom the prevalence of central obesity was 80.9% in those with no education and 59% in those with third-level education. Discussion: The prevalence of overweight and obesity in the Spanish adult elderly population is very high. Some other populations show similar prevalences, especially in Mediterranean countries. Socioeconomic conditions in Spain during the years these cohorts were born may partly explain the high-frequency of obesity.

ObjectiveTo assess the validity and reproducibility of food and nutrient intake estimated with the electronic diet history of ENRICA (DH-E), which collects information on numerous aspects of the Spanish diet.MethodsThe validity of food and nutrient intake was estimated using Pearson correlation coefficients between the DH-E and the mean of seven 24-hour recalls collected every 2 months over the previous year. The reproducibility was estimated using intraclass correlation coefficients between two DH-E made one year apart.ResultsThe correlations coefficients between the DH-E and the mean of seven 24-hour recalls for the main food groups were cereals (r = 0.66), meat (r = 0.66), fish (r = 0.42), vegetables (r = 0.62) and fruits (r = 0.44). The mean correlation coefficient for all 15 food groups considered was 0.53. The correlations for macronutrients were: energy (r = 0.76), proteins (r = 0.58), lipids (r = 0.73), saturated fat (r = 0.73), monounsaturated fat (r = 0.59), polyunsaturated fat (r = 0.57), and carbohydrates (r = 0.66). The mean correlation coefficient for all 41 nutrients studied was 0.55. The intraclass correlation coefficient between the two DH-E was greater than 0.40 for most foods and nutrients.ConclusionsThe DH-E shows good validity and reproducibility for estimating usual intake of foods and nutrients.
