Reporting ≥1 hour per week of moderate activity was associated with a 33% lower mortality risk, and sports participation reduced mortality risk (HR 0.71; 95% CI 0.56-0.91).
Cohort (n=7,456)
Does the intensity and type of physical activity reduce all-cause mortality in adults?
Engaging in at least 1 hour per week of moderate physical activity, particularly sports and do-it-yourself activities, is associated with a significantly lower risk of all-cause mortality.
Hazard Ratio: 0.71 (95% CI 0.56–0.91)
OBJECTIVES: We examined the association of intensity and type of physical activity with mortality. METHODS: We assessed the duration of physical activity by intensity level and type in 7456 men and women from the Whitehall II Study by questionnaire in 1997-1999 (mean ±SD age = 55.9 ± 6.0 years) and 5 years later. All-cause mortality was assessed until April 2009. RESULTS: A total of 317 participants died during the mean follow-up of 9.6 years (SD = 2.7). Reporting at least 1 hour per week of moderate activity was associated with a 33% (95% confidence interval CI = 14%, 45%) lower risk of mortality compared with less than 1 hour. For all physical activity types examined, except housework, a duration of physical activity greater than 0 (≥ 3.5 hours for walking) was associated with lower mortality in age-adjusted analyses, but only the associations with sports (hazard ratio HR = 0.71; 95% CI = 0.56, 0.91) and do-it-yourself activity (HR = 0.68; 95% CI = 0.53, 0.98) remained in fully adjusted analyses. CONCLUSIONS: It is important to consider both intensity and type of physical activity when examining associations with mortality.
Sabia et al. (Fri,) reported a cohort. Physical activity (moderate, sports, or do-it-yourself) vs. Less than 1 hour per week or no participation was evaluated on All-cause mortality (sports participation) (HR 0.71, 95% CI 0.56-0.91). Reporting ≥1 hour per week of moderate activity was associated with a 33% lower mortality risk, and sports participation reduced mortality risk (HR 0.71; 95% CI 0.56-0.91).
