背景：缺乏体力活动与多种不良健康后果有关。交通文献的结果表明，城市环境的方方面面可能会影响步行交通。在这篇文章中，我们检验了城市环境的替代测量和步行行为之间的关联。方法：我们利用第三次全国健康和营养检查调查的数据分析了美国成年人的家庭年龄和步行行为之间的关联。Logistic回归被用来估计优势比和95%的可信区间，并控制性别、种族/民族、年龄、教育水平、家庭收入和活动限制的影响。结果：居住在1946年前和1946-1973年间的成年人比那些住在1973年后建造的房子的成年人每月步行超过或等于20英里的可能性显著增加。这种联系存在于居住在城市和郊区县的人中，但在生活在农村县的人中则没有。在控制了性别、种族/民族、年龄、教育程度、收入和任何与健康相关的活动限制的模型中，也发现了这种关联。结论：这些结果支持了环境变量影响步行频率的假说，并提示家庭年龄可能是以步行形式影响身体活动的城市环境特征的有用替代物。这样的替代措施可以促进使用调查数据测试健康行为的生态模型。
Background: Physical inactivity is associated with multiple adverse health outcomes. Results from the transportation literature suggest that aspects of the urban environment may influence walking for transportation. In this paper we examine the association between a proxy measure of the urban environment and walking behavior.Methods: We analyzed the association between home age and walking behavior in U.S. adults using data from the Third National Health and Nutrition Examination Survey. Logistic regression was used to estimate odds ratios and 95% confidence intervals and to control for the effects of gender, race/ethnicity, age, education level, household income, and activity limitations.Results: Adults who lived in homes built before 1946 and from 1946 to 1973 were significantly more likely to walk 1+ miles greater than or equal to20 times per month than those who lived in homes built after 1973. This association was present among people living in urban and suburban counties, but absent among those living in rural counties. The association was also found in models that controlled for gender, race/ethnicity, age, education, income, and any health-related activity limitation. Other forms of leisure-time physical activity were nor independently associated with home age.Conclusions: These results support the hypothesis that environmental variables influence walking frequency and suggest that home age may be a useful proxy for features of the urban environment that influence physical activity in the form of walking. Such proxy measures could facilitate testing ecologic models of health behavior using survey data.
