To examine the relationship between physical activity and (1) convenience of destinations, measured by whether destinations (such as a park, trail, businesses, and services) are within walking distance of the home, and (2) participants' perception of the quality of their neighborhood surroundings for walking, captured with a global neighborhood "walkability" rating.
Cross-sectional analysis of data obtained in 1999.
Community in southwest Pennsylvania.
Older Caucasian women (n = 149, mean age = 74.2 years). Response rate = 79%.
Walking levels, leisure-time physical activity, and features of the neighborhood environment were measured with interviewer-administered questionnaires. Physical activity was also measured objectively with a pedometer.
Living within walking distance (defined as within a 20-minute walk of home) of a park; biking or walking trail; or department, discount, or hardware store was related to higher pedometer readings (p < .01). In addition, there was a positive trend between the sum of destinations within walking distance of home and activity levels measured by pedometer and questionnaire (p < .01). There was also a positive trend between participants' neighborhood "walkability" rating and activity levels measured by pedometer and questionnaire (p < .01).
These findings suggest that the ability to make utilitarian walking trips from home and the perception of having favorable neighborhood surroundings for walking are associated with increased physical activity levels in older women.
研究身体活动与以下两方面的关系:(1)目的地的便利性,通过目的地(如公园、步道、商业场所和服务设施)是否在离家步行距离范围内来衡量;(2)参与者对其邻里步行环境质量的感知,用全球邻里“可步行性”评分来体现。
对1999年获取的数据进行横断面分析。
宾夕法尼亚州西南部的社区。
老年白人女性(n = 149,平均年龄 = 74.2岁)。应答率 = 79%。
通过访员管理的问卷来测量步行水平、休闲时间身体活动以及邻里环境特征。还使用计步器客观测量身体活动。
居住在公园、自行车道或人行道、或百货公司、折扣店或五金店的步行距离内(定义为离家20分钟步行路程内)与计步器读数较高相关(p < 0.01)。此外,离家步行距离内的目的地总数与计步器和问卷测量的活动水平之间存在正相关趋势(p < 0.01)。参与者的邻里“可步行性”评分与计步器和问卷测量的活动水平之间也存在正相关趋势(p < 0.01)。
这些发现表明,从家中进行功利性步行出行的能力以及对邻里有良好步行环境的感知与老年女性身体活动水平的提高有关。
