Walking to school may be an important source of daily physical activity in children's lives, and government agencies are supporting programs to encourage walking to school (e.g., Safe Routes to School and the CDC's KidsWalk programs). However, little research has looked at differences in behavior across racial/ethnic and income groups.
This cross-sectional study used data from the 2001 National Household Travel Survey to document rates of walking and biking to school among low-income and minority youth in the U.S. (N=14,553). Binary models of the decision to use active transport to school were developed to simultaneously adjust for trip, individual, household, and neighborhood correlates. All analyses were conducted in 2007.
The data showed that low-income and minority groups, particularly blacks and Hispanics, use active travel modes to get to school at much higher rates than whites or higher-income students. However, racial variation in travel patterns is removed by controlling for household income, vehicle access, distance between home and school, and residential density.
Active transportation to school may be an important strategy to increase and maintain physical activity levels for low-income and minority youth. Current policy interventions such as Safe Routes to School have the opportunity to provide benefits for low-income and minority students who are the most likely to walk to school.
步行上学可能是儿童日常生活中身体活动的一个重要来源,政府机构正在支持相关项目以鼓励步行上学(例如“安全上学路”和疾病控制与预防中心的“儿童步行”项目)。然而,很少有研究关注不同种族/族裔和收入群体之间的行为差异。
这项横断面研究使用了2001年全国家庭出行调查的数据,以记录美国低收入和少数族裔青少年(N = 14,553)步行和骑自行车上学的比例。建立了使用主动交通方式上学决策的二元模型,以同时调整出行、个人、家庭和邻里相关因素。所有分析均在2007年进行。
数据显示,低收入和少数族裔群体,尤其是黑人和西班牙裔,使用主动出行方式上学的比例远高于白人或高收入学生。然而,通过控制家庭收入、车辆拥有情况、家与学校之间的距离以及居住密度,出行模式的种族差异得以消除。
步行上学可能是提高和维持低收入和少数族裔青少年身体活动水平的一项重要策略。当前诸如“安全上学路”之类的政策干预措施有机会为最有可能步行上学的低收入和少数族裔学生带来益处。
