| Annotation | In this US study, participants were 9777 men given two preventive medical examinations, each including an assessment of physical fitness by maximal exercise and evaluation of health status (mean follow-up of subsequent examination, 5.1 years). The highest age-adjusted all cause death rate was observed in men who were unfit at both examinations (122/10000 man-years); the lowest death rate was in men who were physically fit at both examinations (39.6/10000 man-years). Men who improved from unfit to fit between examinations had an age-adjusted death rate of 67.7/10000 man-years. This is a reduction in mortality risk of 44% (95% confidence interval, 25% to 59%) relative to men who remained unfit. Improvement in fitness was associated with lower death rates after adjusting for age, health status, and other risk factors of premature mortality. Those who maintained or improved adequate physical fitness were less likely to die from all causes and from cardiovascular disease during follow-up than persistently unfit men. Doctors should encourage unfit men to improve their fitness by starting a physical activity programme. (RH). |
