Abstract

Objective:

The relationship between mortality and physical activity in the general population is unclear.

Design and Method:

Using data from 1,920 men and women aged over 40 years who participated in the Tanushimaru Study, physical activity was assessed by self-report using the Baecke questionnaire at baseline in 1999. The questionnaire was constituted by three physical activity categories: work index, sports index and non-sports index. Total index was summed up by the three indices. Multivariable adjusted hazard ratios (HR) and 95% confidence intervals (CI) were calculated using Cox regression models.

Results:

During a median follow-up of 13.8 years, a total of 343 died. In conventional coronary risk factors, systolic blood pressure (p = 0.088), fasting plasma glucose (p = 0.027) and smoking habit (p < 0.001) were significantly and marginally associated with mortality. Significant inverse associations were found between total index and mortality after adjustment for age and gender. Compared with poor physical activity, the adjusted HR (95% CI) for ideal physical activity were 0.125 (0.017–0.914).

Conclusions:

These data suggest that ideal physical activity showed was a reduced risk of mortality as well as conventional coronary risk factors.
