In this paper and prospective study, we examine the number of healthy behaviors and the incidence of disability in community-dwelling older adults aged 65 years and older.
Participants (N = 4483) were residents of Obu, Japan who were asked about regular exercise, smoking status, and sleep duration. Demographic variables, history of disease, physi- cal function, and cognitive function were measured as confounders. Information about disabil- ity was obtained from the Obu City Office.
At 24 months after baseline assessment, 165 participants (3.7%) were certified as having disability. Participants with 2 healthy behaviors had a 1.61-fold increased risk of disability (95% CI: 1.08 -2.42) compared with those with 3 healthy behaviors; those with one or no healthy behaviors had a 2.01-fold risk (95% CI: 1.26-3.19) even though adjusting for confounders.
The number of healthy behaviors was associated with the incidence of disability, with the hazard ratios increasing progressively as the number of healthy behaviors decreased.
在本文及前瞻性研究中，我们调查了65岁及以上社区居住老年人的健康行为数量和残疾发生率。
参与者（N = 4483）为日本大府市居民，被询问了定期锻炼、吸烟状况和睡眠时间。测量了人口统计学变量、疾病史、身体功能和认知功能作为混杂因素。残疾信息来自大府市政府办公室。
在基线评估24个月后，165名参与者（3.7%）被认证为残疾。与有3种健康行为的参与者相比，有2种健康行为的参与者残疾风险增加了1.61倍（95%置信区间：1.08 - 2.42）；即使对混杂因素进行了调整，有1种或没有健康行为的参与者残疾风险仍为2.01倍（95%置信区间：1.26 - 3.19）。
健康行为数量与残疾发生率相关，随着健康行为数量减少，风险比逐渐增加。
