Leisure time physical activity and the 16-year risks of mortality from coronary heart disease and all-causes in the Multiple Risk Factor Intervention Trial (MRFIT).
PURPOSE To examine the long-term association of leisure time physical activity ( LTPA ) and risk of death from coronary heart disease ( CHD ) and all-causes . METHODS Data are from a prospect i ve study of 12,138 middle-aged men at high risk for CHD participating in the MRFIT . Men were classified into deciles based on average min/d of LTPA reported at baseline , which were compared with cumulative CHD and all-cause mortality endpoints at the 16-year follow-up . RESULTS Men in the least-active decile of LTPA who averaged 4.9 min/d of LTPA ( range 0 to .9 min/d ) had excess age-adjusted mortality rates of 29 % and 22 % for CHD and all-causes , respectively , as compared to those in combined deciles 2 to 4 , who averaged 22.7 min/d of predominantly light and moderate LTPA ( range 10 - 36 min/d ) . No further decrement in mortality rates was noted in those in the higher declines of LTPA . These associations remained significant ( P < 0.05 ) after proportional hazards adjustments for additional possible confounding variables . CONCLUSION These data suggest that a relatively small amount ( 10 to 36 min/d ) of daily moderate intensity LTPA can significantly reduce premature mortality , particularly from CHD , in middle-aged and older men at high risk for CHD
