As people age, they spend more time in and around their domestic environments, within which opportunities for health-enhancing physical activity (PA) may be limited. We examined the associations of frequency of excursions from home with accelerometer-determined PA and the total and prolonged sedentary behavior (SB, sitting for ≥30 min) among community-dwelling older adults.
Overall, 434 older adults (men, 57.1 %; age, 70-79 years) wore an accelerometer (HJA-350IT, Omron Healthcare) for 7 days. Time spent in SB, light-intensity PA (LPA), moderate-to-vigorous PA (MVPA), and prolonged SB bout (≥30 min) were calculated. Frequencies of excursions from home were categorized as 0-3, 4-5, and 6-7 days/week. Associations of excursions with PA and SB were tested by analysis of covariance adjusted for sociodemographic characteristics.
Frequencies were 14.3 %, 31.1 %, and 54.6 % for excursions 0-3, 4-5, and 6-7 days/week, respectively. For men, less frequent excursions from home were significantly associated with less MVPA and more total and prolonged SB times (estimated means [minutes/day]: MVPA, 32, 42, and 48; total SB, 589, 549, and 539; prolonged SB, 344, 288, and 265; respectively; p < 0.05). LPA was not statistically significant (p = 0.09). For women, less frequent excursions were significantly associated with all PA outcomes (SB: 536, 497, and 467; prolonged SB: 260, 213, and 204; LPA: 328, 363, and 379; MVPA: 36, 39, and 54, respectively).
Among community-dwelling Japanese older adults, more frequent excursions from home were associated with more PA, less SB, and more-favorable SB patterns, suggesting a potential strategy for preventive-health initiatives.
随着人们年龄的增长，他们更多地在家庭环境中及其周围活动，而这可能会限制促进健康的身体活动（PA）的机会。我们研究了社区居住的老年人离开家的频率与加速度计测定的 PA 以及久坐行为（SB，坐≥30 分钟）的总时间和长时间段之间的关联。
共有 434 名老年人（男性，57.1%；年龄 70-79 岁）佩戴加速度计（HJA-350IT，欧姆龙保健）7 天。计算 SB、低强度 PA（LPA）、中等到剧烈 PA（MVPA）和长时间 SB 段（≥30 分钟）的时间。离家频率分为 0-3、4-5 和 6-7 天/周。通过调整社会人口特征的协方差分析，检验了离家频率与 PA 和 SB 的关联。
离家频率分别为 0-3、4-5 和 6-7 天/周的频率分别为 14.3%、31.1%和 54.6%。对于男性，较少离家与 MVPA 减少以及总 SB 时间和长时间 SB 时间增加有关（估计均值[分钟/天]：MVPA，32、42 和 48；总 SB，589、549 和 539；长时间 SB，344、288 和 265；p<0.05）。LPA 无统计学意义（p=0.09）。对于女性，较少离家与所有 PA 结果显著相关（SB：536、497 和 467；长时间 SB：260、213 和 204；LPA：328、363 和 379；MVPA：36、39 和 54）。
在日本社区居住的老年人中，更多离家频率与更多 PA、更少 SB 和更有利的 SB 模式相关，这表明了一种预防健康倡议的潜在策略。
