背景：老年人很少在户外活动，而且许多人缺乏身体活动。尚未在老年人中研究户外体育活动与自评健康之间的关系。本文旨在评估身体活动地点与自评健康状况和身体活动分钟数的关系。这是 2005 年至 2008 年对 66 岁及以上的流动成年人进行的一项观察性研究。参与者（N = 754）完成了身体活动地点和自我评估健康状况的调查测量，并佩戴加速度计来客观评估身体活动。针对邻域聚类效应进行调整的混合模型线性回归程序。比较三种体力活动环境（仅室内、仅室外、室内和室外）的自评健康状况和体力活动分钟数的差异。结果：与仅在室内进行体力活动的人相比，每周至少进行一次户外体力活动的人进行中度至剧烈体力活动的分钟数显着更长。自评健康状况与身体活动显着相关，但不随活动地点的不同而变化。结论：在户外进行身体活动的老年人积累的身体活动量明显更多，但自评健康状况并不显着高于在室内进行身体活动的老年人。
Background: Older adults spend little time outdoors and many are physically inactive. The relationship between outdoor physical activity and self rated health has not been studied in older adults. This paper aimed to assess the relation of location of physical activity to self rated health and physical activity minutes. This was an observational study of ambulatory adults 66 years and older conducted in 2005-2008. Participants (N = 754) completed survey measures of physical activity location and self rated health, and wore an accelerometer to objectively assess physical activity. A mixed model linear regression procedure adjusted for neighborhood clustering effects. Differences in self rated health and physical activity minutes were compared across three physical activity settings (indoor only, outdoor only, both indoor and outdoor).Results: Minutes of moderate to vigorous physical activity were significantly greater in those who were physically active at least once a week outdoors compared with those who were physically active indoors only. Self rated health was significantly related to being physically active but did not vary by location of activity.Conclusions: Older adults who were physically active outdoors accumulated significantly more physical activity, but self-rated health was not significantly greater than those being physically active indoors.
