Low physical activity as a predictor for total and cardiovascular disease mortality in middle-aged men and women in Finland.

AIMS: To investigate separately for men and women whether moderate or high leisure time physical activity, occupational physical activity, and commuting activity are associated with a reduced cardiovascular disease (CVD) and all-cause mortality, independent of CVD risk factors and other forms of physical activity.

METHODS AND RESULTS: Prospective follow-up of 15,853 men and 16,824 women aged 30-59 years living in eastern and south-western Finland (median follow-up time 20 years). CVD and all-cause mortality were lower (9-21%) in men and women (2-17%) who were moderately or highly physically active during leisure time. Moderate and high levels of occupational physical activity decreased CVD and all-cause mortality by 21-27% in both sexes. Women spending daily 15 min or more in walking or cycling to and from work had a reduced CVD and all-cause mortality before adjustment for occupational and leisure time physical activity. Commuting activity was not associated with CVD or all-cause mortality in men.

CONCLUSION: Moderate and high levels of leisure time and occupational physical activity are associated with a reduced CVD and all-cause mortality among both sexes. Promoting already moderate levels of leisure time and occupational physical activity are essential to prevent premature CVD and all-cause mortality.
