Relative Risks of Mortality According to Joint Categories of Aerobic and Strength Training: Women's Health Study

Outcome	Aerobic MVPA <150 Min/Wk and No Strength Training	Aerobic MVPA ≥150 Min/Wk and No Strength Training	Aerobic MVPA <150 Min/Wk and Any Strength Training	Aerobic MVPA ≥150 Min/Wk and Any Strength Training	P Value for Interaction
All‐cause death
Cases (person‐years)	1620 (156 331)	979 (115 418)	169 (23 472)	287 (51 622)
HR (95% Cl)	Reference	0.71 (0.64–0.79)	0.74 (0.65–0.85)	0.54 (0.47–0.61)	0.33
CVD death
Cases (person‐years)	228 (156 331)	133 (115 418)	17 (23 472)	33 (51 622)
HR (95% Cl)	Reference	0.74 (0.56–0.98)	0.75 (0.53–1.07)	0.43 (0.29–0.63)	0.23
Cancer death
Cases (person‐years)	348 (156 331)	259 (115 418)	36 (23 472)	105 (51 622)
HR (95% Cl)	Reference	0.97 (0.79–1.19)	0.91 (0.70–1.18)	0.93 (0.74–1.17)	0.45

All groups are mutually exclusive. HRs (95% CIs) are calculated on the basis of cumulative average values. Cases (person‐years) are shown on the basis of the categories of baseline physical activities. Multivariable model is adjusted for age, race, education, postmenopausal status, hormone use, smoking status, parental history of myocardial infarction or cancer, alcohol intake, energy intake, saturated fat intake, fiber intake, fruit and vegetable intake, physical examination for screening, body mass index, incidence of hypertension, high cholesterol, CVDs, diabetes mellitus, and cancer before and during follow‐up, and trial randomization. CI indicates confidence interval; CVD, cardiovascular disease; HR, hazard ratio; and MVPA, moderate‐to‐vigorous physical activity.
