预计在老龄化社会中，与疟疾有关的死亡率会增加。这项前瞻性队列研究旨在研究每天步行（1小时/天）是否可以降低缺乏其他锻炼习惯的老年人的肺炎相关死亡率。我们分析了来自日本特定健康检查的数据，这些数据来自7个县82个市的年龄≥ 65岁的参与者，他们每天参加步行，但不经常参加其他形式的运动（n= 132，448）。在2008年至2014年期间进行的基线调查中评估了有关步行习惯和健康相关指标的信息。对与肺炎相关的死亡率和全因死亡率进行了中位3.4年的随访。我们进行了一个竞争风险模型与倾向评分匹配，以评估日常步行习惯和肺炎相关死亡率之间的关联。我们的倾向匹配分析显示，在缺乏其他运动习惯的老年人中，每日步行与肺炎相关死亡率之间存在显著相关性，因此亚危险比和95%置信区间为0.58（0.39，0.86）。这项研究扩展了先前关于运动对肺炎影响的研究结果，证明每天单独散步足以降低不经常从事其他运动习惯的老年人的肺炎相关死亡率。
Pneumonia-related mortality is expected to increase in aging societies. This prospective cohort study examined whether daily walking (1hour/day) could reduce pneumonia-related mortality among older people who lacked other exercise habits. We analysed data from Japanese Specific Health Checkup across 82 municipalities in 7 prefectures among participants aged >= 65 years who participated in daily walking but did not regularly engage in other forms of exercise (n=132,448). Information on walking habits and health-related indicators was assessed at a baseline survey conducted between 2008 and 2014. Pneumonia-related and all-cause mortality were followed for a median of 3.4 years. We performed a competing risk model with propensity score matching to evaluate the association between daily walking habits and pneumonia-related mortality. Our propensity-matched analysis revealed a significant association between daily walking and pneumonia-related mortality among older people who lacked other exercise habits, such that the sub-hazard ratio and 95% confidence intervals were 0.58 (0.39, 0.86). This study extends the findings of previous research on the effects of exercise on pneumonia by demonstrating that daily walking alone is sufficient to reduce pneumonia-related mortality among older people who do not regularly engage in other exercise habits.
