A pooled analysis of population-based surveys in UK revealed that leisure time physical activity was associated with reduced mortality risk. The analysis included 63 591 adult respondents (45.9% male; 44.1% female; mean [SD] age, 58.6 [11.9] years). Data were collected from 1994 to 2012 and analyzed in 2016. Compared with inactive participants (reporting no moderate- or vigorous-intensity activities), the hazard ratio (HR) for all-cause, cardiovascular disease or cancer mortality was 0.66, 0.60 and 0.83, respectively in insufficiently active (<150 min/wk) participants; 0.70, 0.60 and 0.82, respectively, in weekend warrior (≥150 min/wk) participants who reported 1 to 2 sessions per week; and 0.65, 0.59 and 0.79, respectively in regularly active (≥150 min/wk from ≥3 sessions) participants. The findings suggest that different leisure time physical activity patterns are all associated with reduced mortality risks.
