体力活动 (PA) 对老年人的健康有益。研究表明，接触大自然和在户外度过的时间也可能对健康产生影响。老年人是我们人口中最不活跃的群体，与其他年龄段的人相比，他们在户外度过的时间可能更少。对居住在退休社区的 117 名老年人进行了评估，其中包括在 PA 的时间、户外时间和各种健康结果之间的关系。参与者佩戴加速计和 GPS 设备 7 天。他们还完成了身体、认知和情感功能的评估。采用方差分析，对 ±30 分钟 PA 和户外时间的主要效应和交互效应进行测试。对于那些在 PA 或户外活动超过 30 分钟的人来说，抑郁症状、对跌倒的恐惧和自我报告的功能存在显着差异。完成 400 m 步行的时间仅因 PA 时间而显着不同。生活质量和认知功能评分没有显着差异。相互作用也不显着。这项研究是第一个证明同时使用加速度计和 GPS 数据来评估老年人 PA 位置的可行性的研究之一。未来的分析将揭示潜在的因果关系，并为户外活动提供指导。
Physical activity (PA) provides health benefits in older adults. Research suggests that exposure to nature and time spent outdoors may also have effects on health. Older adults are the least active segment of our population, and are likely to spend less time outdoors than other age groups. The relationship between time spent in PA, outdoor time, and various health outcomes was assessed for 117 older adults living in retirement communities. Participants wore an accelerometer and GPS device for 7 days. They also completed assessments of physical, cognitive, and emotional functioning. Analyses of variance were employed with a main and interaction effect tested for ±30 min PA and outdoor time. Significant differences were found for those who spent >30 min in PA or outdoors for depressive symptoms, fear of falling, and self-reported functioning. Time to complete a 400 m walk was significantly different by PA time only. QoL and cognitive functioning scores were not significantly different. The interactions were also not significant. This study is one of the first to demonstrate the feasibility of using accelerometer and GPS data concurrently to assess PA location in older adults. Future analyses will shed light on potential causal relationships and could inform guidelines for outdoor activity.
