There is a paucity of information about mortality related to light-intensity physical activity (LPA) in the older population. We examine associations between and mortality, focusing on effect dose-response relationship mortality.We analyzed total 58,537 participants aged ≥ 65 years (mean age, 73.9 ± 5.8 years; male, 36.0%) Korean National Health Insurance Service database 2009 2012. The Date end follow-up was December 31, 2013. Individuals were divided into four categories according intensity: totally sedentary (43.3%), LPA only (35.8%), moderate- vigorous-intensity (MVPA) (16.3%), MVPA (4.5%). Physical quantified using standardized self-reported questionnaires which composed duration frequency activity.During mean 39.6 14.0 months, 5,651 (9.7%) deaths occurred. Compared with individuals, those only, MVPA, groups showed 26% [hazard ratio (HR) 0.74, 95% confidence interval (CI) 0.68-0.82], 27% (HR 0.73, CI 0.63-0.84), 34% 0.66, 0.54-0.79) lower all-cause risk, showing an inverse intensity risk. In contrast, represented stronger association CV (LPA: HR 0.76, 0.62-0.92; MVPA: 0.55-0.999; 0.57, 0.37-0.87). Among performing alone, less than recommended dose had (1-249 MET-min/week: 0.67-0.82, 250-499 0.65, 0.59-0.72).Physical activity, even low doses LPA, associated reduced risk elderly This study may motivate individuals engage any for benefits.
