Leisure-time physical activity and mortality in a multiethnic prospective cohort study: the Northern Manhattan Study.

摘要: Abstract Purpose To examine whether the survival benefit of exercise is modified by obesity. Methods In Northern Manhattan Study, we collected baseline sociodemographics and cardiovascular disease risk factors. The primary exposure was leisure-time physical activity (LTPA) outcomes were total, vascular, nonvascular deaths (non-VaD). LTPA defined as any versus none metabolic equivalent score category (total weighted intensity). We used Cox models to estimate hazard ratios (HRs) 95% confidence intervals (CIs). Results A total 3298 participants (mean age 69 years, 52% Hispanic, 63% women) followed over a mean 11.8 years with 1589 (641 819 nonvascular). Any (adjusted HR: 0.84, CI: 0.75–0.94) associated reduced all-cause mortality non-VaD, but not VaD. found an interaction (P  Conclusions no evidence independent among those BMI more than 30. health benefits should be considered in context
