背景 低强度活动对老年男性长寿的潜在益处尚未得到明确记录。我们研究了一组不吸烟且身体能够每天参加低强度活动的退休男性队列中步行与死亡率之间的关系。方法我们研究了 707 名参加檀香山心脏计划的不吸烟退休男性，年龄为 61 至 81 岁。步行距离（每天英里）是在 1980 年至 1982 年间进行的基线检查中记录的。在 12 年的随访期间收集了总体死亡率（任何原因）的数据。结果 在随访期间，有 208 人死亡。调整年龄后，每天步行少于 1 英里（1.6 公里）的男性的死亡率几乎是每天步行超过 2 英里（3.2 公里）的男性的两倍（40.5% vs. 23.8%，P=0.001）。最活跃的步行者 12 年后的累积死亡发生率在最不活跃的男性中不到 7 年就达到了。在调整总体活动测量和其他危险因素后，步行距离仍然与死亡率呈负相关（P = 0.01）。结论我们对体力正常的老年男性的研究结果表明，经常步行与较低的总体死亡率相关，鼓励老年人步行可能有益于他们的健康。 (C) 1998 年，马萨诸塞州医学会。
Background The potential benefit of low-intensity activity in terms of longevity among older men has not been clearly documented. We examined the association between walking and mortality in a cohort of retired men who were nonsmokers and physically capable of participating in low-intensity activities on a daily basis.Methods We studied 707 nonsmoking retired men, 61 to 81 years of age, who were enrolled in the Honolulu Heart Program. The distance walked (miles per day) was recorded at a base-line examination, which took place between 1980 and 1982. Data on overall mortality (from any cause) were collected over a 12-year period of follow-up.Results During the follow-up period, there were 208 deaths. After adjustment for age, the mortality rate among the men who walked less than 1 mile (1.6 km) per day was nearly twice that among those who walked more than 2 miles (3.2 km) per day (40.5 percent vs. 23.8 percent, P=0.001). The cumulative incidence of death after 12 years for the most active walkers was reached in less than 7 years among the men who were least active. The distance walked remained inversely related to mortality after adjustment for overall measures of activity and other risk factors (P = 0.01).Conclusions Our findings in older physically capable men indicate that regular walking is associated with a lower overall mortality rate, Encouraging elderly people to walk may benefit their health.
