Key result

Physical exercise expending ≥2000 kcal/week in middle age was associated with a 25% reduced risk of cardiovascular disease and death compared with less active men.

Why the study?

Does physical exercise reduce the risk of cardiovascular disease and death in adult men?

Key Points

This research aims to understand how early athleticism and ongoing physical activity affect health outcomes and longevity.
Longitudinal study observing 52,000 men from Harvard College and the University of Pennsylvania from 1916 to 1950.
Follow-up with questionnaires assessing physical activity and health outcomes in a 10-year period.
Analysis of death rates and cardiovascular disease prevalence in relation to activity levels and intensity.
Men who maintained high levels of physical activity had a 25% reduced risk of cardiovascular disease and death compared to less active counterparts.
Sedentary students who became active later had lower risks of CVD and death than former athletes who reduced activity.
Men engaging in moderately vigorous sports gained 1.5 years in life expectancy by age 90 compared to less active men.

Does physical exercise reduce the risk of cardiovascular disease and death in adult men?

Population

52,000 men who entered Harvard College or the University of Pennsylvania between 1916 and 1950, including sub-cohorts of alumni aged 35-74 years and 17,815 Harvard alumni aged 45-84 years.

Intervention

Physical exercise (sports play, walking, and stair climbing) expending ≥ 2000 kcal/week, or moderately vigorous to vigorous sports play.

Comparator

Less active men (expending < 2000 kcal/week or engaging in less vigorous activities) or sedentary lifestyle.

Outcome

Development of cardiovascular disease (CVD) and death.hard clinical

Main Result

Effect estimate: 25% reduced risk

Maintaining a physically active lifestyle into middle age, particularly with moderately vigorous intensity, significantly reduces the risk of cardiovascular disease and mortality.

Discussion

No takes yet. Share an insight, caveat, or question.

Implication

May support activity promotion in middle-aged men; leaves open causality pending randomized trials.

Paffenbarger et al. (1998) conducted a cohort in Cardiovascular disease and death (n=52,000). Physical exercise vs. Less active men was evaluated on Cardiovascular disease and death (25% reduced risk). Physical exercise expending ≥2000 kcal/week in middle age was associated with a 25% reduced risk of cardiovascular disease and death compared with less active men.
