Antioxidant Vitamin Intake and Mortality: The Leisure World Cohort Study
To assess the relationship between antioxidant vitamin intake and all-cause mortality in older adults, we examined these associations using data from the Leisure World Cohort Study, a prospective study of residents of the Leisure World retirement community in Laguna Hills, California. In the early 1980s, participants (who were aged 44–101 years) completed a postal survey, which included details on use of vitamin supplements and dietary intake of foods containing vitamins A and C. Age-adjusted and multivariate-adjusted (for factors related to mortality in this cohort—smoking, alcohol intake, caffeine consumption...

Disease prevalence based on older people's self-reports increased, but patient–general practitioner agreement remained stable, 1992–2009
Conclusion: Trends in self-reported chronic diseases may be influenced by changes in reporting behavior, and future studies should take this possibility into account.

Cross-country variation in additive effects of socio-economics, health behaviors, and comorbidities on subjective health of patients with diabetes
Conclusion: Countries show different profiles of social and behavioral determinants of subjective health among patients with diabetes. Our study suggests that universal programs that assume that determinants of well-being are similar across different countries may be over-simplistic. Thus instead of universal programs that use one protocol for health promotion of patients in all countries, locally designed interventions should be implemented in each country.

Developmental trajectories of body mass index throughout adulthood: evidence from the national population health survey
This study will apply group-based trajectory modeling to map adult body mass trajectories with an age axis spanning 18 to 64 years, based on the longitudinal data from Statistics Canada's National Population Health Survey 1994 (n=17276). Group-based trajectory modeling is a powerful semi-parametric statistical approach that captures information about inter-individual differences within a large population. Risk factors (time-instable covariates) including gender and age cohort, and time-varying covariates such as diet, daily activities, education level, income, lifestyle (sleep, smoking, and alcohol), stress, and mental hea...

Arthritis: its prevalence, risk factors, and association with cardiovascular diseases in the United States, 1999 to 2008
Abstract: Objective: Arthritis is associated with cardiovascular diseases (CVDs). However, there are limited epidemiologic studies on arthritis in a national survey study. We therefore investigated the prevalence of self-reported arthritis and its association with CVDs.Methods: Data from 15,888 subjects aged 40 years or older in the United States National Health and Nutrition Examination Survey 1999 through 2008 were analyzed. CVD was defined as a self-reported history of heart attack, congestive heart failure, coronary heart disease, angina, or stroke.Results: The overall prevalence of self-reported arthritis in subjects ...
