有人担心，老年人的预防措施可能会在没有改善健康的情况下增加存活率，从而增加虚弱程度。我们调查了锻炼对社区老年人健康改善、恶化和死亡的可能性的影响。在加拿大的健康和老龄化研究中，健康状况是通过基于健康缺陷数量的脆弱指数来衡量的。使用有效的自填式问卷，将锻炼分为高锻炼或低锻炼/不锻炼两类。在5年后重新评估健康状况和生存情况。在6297名符合条件的参与者中，5555人拥有完整的数据。在所有级别的虚弱中，75岁以上锻炼的男性和女性的死亡率与65岁至75岁不锻炼的同龄人相似。此外，尽管所有运动的人都有更大的机会改善他们的健康状况，但最大的好处是那些更虚弱的人(例如，在基线水平上，有2个缺陷的人中，34%的高运动者改善或稳定，而在2个缺陷的人中，低/不锻炼的人改善或稳定的比例为26%，而在9个缺陷的人中，高运动者的改善或稳定性改善的比例为40%，而低/不锻炼的人的改善/稳定性为22%)。在居住在社区的老年人中，锻炼减弱了年龄对所有脆弱程度的死亡率的影响。运动对那些在基线水平上更虚弱的人的健康状况的改善是最大的好处。因此，锻炼的净效果应该是改善人口一级的健康状况。
Concern has been expressed that preventive measures in older people might increase frailty by increasing survival without improving health. We investigated the impact of exercise on the probabilities of health improvement, deterioration and death in community-dwelling older people. In the Canadian Study of Health and Aging, health status was measured by a frailty index based on the number of health deficits. Exercise was classified as either high or low/no exercise, using a validated, self-administered questionnaire. Health status and survival were re-assessed at 5 years. Of 6297 eligible participants, 5555 had complete data. Across all grades of frailty, death rates for both men and women aged over 75 who exercised were similar to their peers aged 65 to 75 who did not exercise. In addition, while all those who exercised had a greater chance of improving their health status, the greatest benefits were in those who were more frail (e.g. improvement or stability was observed in 34% of high exercisers versus 26% of low/no exercisers for those with 2 deficits compared with 40% of high exercisers versus 22% of low/no exercisers for those with 9 deficits at baseline). In community-dwelling older people, exercise attenuated the impact of age on mortality across all grades of frailty. Exercise conferred its greatest benefits to improvements in health status in those who were more frail at baseline. The net effect of exercise should therefore be to improve health status at the population level.
