Leisure-time physical activity and mortality from influenza and pneumonia: a cohort study of 577 909 US adults

Figure 1. Adjusted HRs (95% CI) for influenza and pneumonia mortality based on weekly min of moderate-intensity equivalent aerobic physical activity. Adjusted for sex; age; race/ethnicity; education; marital status; smoking status; alcohol consumption; body mass index; presence of heart disease, stroke, hypertension, diabetes, cancer, chronic obstructive pulmonary disease and asthma; influenza and pneumococcal vaccination status and muscle-strengthening activity category. Based on sample adults who participated in the National Health Interview Survey from 1998 to 2018 and were eligible for linkage to the National Death Index through 2019 (n=577 909).
