Light physical activity predicts long-term mortality in individuals with a different cardiovascular health status: a cohort study.

Studies have showed that LIPA seems to be favorably associated with mortality in the general population and illness individuals, but the association between different cardiovascular health status and mortality is not clear.  After adjustment , the HRs of LIPA in individuals with CVRF and CVD from quartiles 2-4 were less than 1, which were 0.78 (95%CI, 0.61 ~ 0.99; P = 0.042), 0.63 (95%CI, 0.47 ~ 0.83; P = 0.001), 0.55（95%CI, 0.40 ~ 0.76; P < 0.001）, and 0.52 (95%CI, 0.37 ~ 0.74; P < 0.001)，0.39 (95%CI, 0.27 ~ 0.58; P < 0.001), 0.33 (95%CI, 0.22 ~ 0.51; P < 0.001)  LIPA is beneficial for reducing mortality, but the shape of the association depends on cardiovascular health status.
