  • 1-2 sessions of moderate or vigorous physical activity/wk are enough to reduce risks for all-cause, cardiovascular disease (CVD), and cancer-related mortality.

Why this matters

Study design

  • Pooled activity data for 63,591 adults aged ≥40 y (mean, 58.6 y; 45.9% male) participating in the England and Scottish Health Survey from 1994 to 2012, matched with mortality records.
  • Regular activity (11.1%) was defined as ≥150 min/wk moderate-intensity or ≥75 min/wk vigorous-intensity exercise; weekend warriors (3.7%) achieved this in 1-2 sessions, whereas insufficiently active persons (22.4%) did not achieve either endpoint.
  • Models were adjusted for age, sex, smoking, occupation, and long-standing illness, using inactive adults (62.8%) as a comparator.
