Neighborhood parks play an important role in promoting physical activity. We examined the effect of activity area, condition, and presence of supporting features on number of park users and park-based physical activity levels.
37 parks and 154 activity areas within parks were assessed during summer 2008 for their features and park-based physical activity. Outcomes included any park use, number of park users, mean and total energy expenditure. Independent variables included type and condition of activity area, supporting features, size of activity area, gender, and day of week. Multilevel models controlled for clustering of observations at activity area and park levels.
Type of activity area was associated with number of park users, mean and total energy expenditure, with basketball courts having the highest number of users and total energy expenditure, and playgrounds having the highest mean energy expenditure. Condition of activity areas was positively associated with number of basketball court users and inversely associated with number of green space users and total green space energy expenditure. Various supporting features were both positively and negatively associated with each outcome.
This study provides evidence regarding characteristics of parks that can contribute to achieving physical activity goals within recreational spaces.
社区公园在促进身体活动方面发挥着重要作用。我们研究了活动区域、状况以及配套设施的存在对公园使用者数量和基于公园的身体活动水平的影响。
在2008年夏季对37个公园及公园内的154个活动区域进行了评估，考察其特征和基于公园的身体活动情况。结果包括是否使用公园、公园使用者数量、平均能量消耗和总能量消耗。自变量包括活动区域的类型和状况、配套设施、活动区域大小、性别以及星期几。多水平模型控制了活动区域和公园层面观测值的聚类情况。
活动区域类型与公园使用者数量、平均能量消耗和总能量消耗相关，篮球场的使用者数量和总能量消耗最高，游乐场的平均能量消耗最高。活动区域状况与篮球场使用者数量呈正相关，与绿地使用者数量和绿地总能量消耗呈负相关。各种配套设施与各项结果既有正相关也有负相关。
本研究提供了有关公园特征的证据，这些特征有助于在休闲空间实现身体活动目标。
