[BDSP. Notice produite par INIST-CNRS pIppR0xG. Diffusion soumise à autorisation]. Background There are few longitudinal data on physical activity patterns from mid-life into older age. The authors examined associations of self-reported physical activity, adiposity and socio-demographic factors in mid-life with objectively assessed measures of activity in older age. Methods Participants were 394 healthy men and women drawn from the Whitehall II population-based cohort study. At the baseline assessment in 1997 (mean age 54 years), physical activity was assessed through self-report and quantified as metabolic equivalent of task hours/week. At the follow-up in 2010 (mean age 66 years), physical activity was objectively measured using accelerometers worn during waking hours for seven consecutive days (average daily wear time 891+/-68 min/day). Results Self-reported physical activity at baseline was associated with objectively assessed activity at follow-up in various activity categories, including light-moderate-and vigorous-intensity activity (all ps
