The impact of lifestyle factors on cancer mortality in U.S. population has not been thoroughly explored.
PURPOSE: We examined the combined effects of cardiorespiratory fitness, never smoking, and normal waist girth on total cancer mortality in men.
METHODS: We followed a total of 24,741 men ages 20-82 years who participated in the Aerobics Center Longitudinal Study. A low-risk profile was defined as never smoking, moderate or high fitness, and normal waist girth, and they were further categorized as having 0, 1, 2, or 3 combined low-risk factors.
RESULTS: During an average of 14.5 years of follow-up, there were a total of 384 cancer deaths. After adjustment for age, examination year, and multiple risk factors, men who were physically fit, never smoked, and had a normal waist girth had a 62% lower risk of total cancer mortality (95% confidence interval [CI], 45%-73%) compared with men with zero low-risk factors. Men with all 3 low-risk factors had a 12-year (95% CI: 8.6-14.6) longer life expectancy compared with men with 0 low-risk factors. Approximately 41% (95% CI, 17%-56%) of total cancer deaths might have been avoided if the men had maintained all three low-risk factors.
CONCLUSIONS: Being physically fit, never smoking, and maintaining a normal waist girth is associated with lower risk of total cancer mortality in men.
