项目摘要

DESCRIPTION (provided by applicant): Obesity and physical activity have been associated with decreased risk and improved outcomes for multiple cancers. In the US, childhood obesity is increasing while physical activity levels decline as children age. Since both track strongly into adulthood, the risk of subsequent obesity and presumably cancer in adulthood is increased. As a result, preventing childhood obesity and improving physical activity have been selected as major public health goals to reduce the risk and sequelae of obesity and cancer in the US. Walking to school is a national health objective of Healthy People 2010, and is consistent with the American Cancer Society's recommendation for children to engage in at least 60 minutes per day of moderate to vigorous physical activity. Walking to school is associated with 24-40 more minutes of moderate to vigorous physical activity per day. Increasing child pedestrian activity could increase the risk of injuries; however, walking with an adult reduced this risk by almost 70%. A walking school bus (WSB) addresses both physical activity and safety concerns by providing a period of physical activity supervised by several responsible adults and teaching opportunities around pedestrian safety skills on the way to and from school. Randomized controlled-studies are lacking on the impact of WSBs on children's mode of school transport, pedestrian safety, daily physical activity, and health. We seek to help fill this important gap. The goals of this research plan will be 1) to determine socio-demographic predictors of student participation in the WSB, 2) to evaluate the impact of a WSB program to decrease parental barriers to allowing their children to walk to and from school, to increase pedestrian safety behaviors, to increase walking to school, to increase daily moderate to vigorous physical activity, and to decrease weight gain in 4th grade students, and 3) to gain experience in implementing a WSB program with parent volunteers and determine parental acceptability and participation. Our specific aims include: (1) To conduct a longitudinal cohort study of 4th grade students and their parents to determine predictors of WSB participation related to socio-demographic data; (2) To successfully recruit 30 children per school from four public elementary schools (n=120) to participate in a pilot WSB intervention and conduct a 4-month pilot group randomized controlled trial to assess its impact in decreasing parents' perceived barriers to allowing their children to walk to and from school, to increase children walking to school, to increase child pedestrian safety behaviors, to increase daily moderate to vigorous physical activity, and to decrease weight gain in 4th grade students; and (3) To conduct a 4-month feasibility trial of the WSB program staffed by parent volunteers, collect process data, and conduct semistructured qualitative interviews with parents regarding acceptability. PUBLIC HEALTH RELEVANCE: The walking school bus (WSB) aims to increase students' walking to and from school, pedestrian safety, physical activity, and to decrease weight gain. The WSB will provide a targeted, population-based approach to address children's physical inactivity and the epidemic of childhood obesity. This in turn should lead to a substantial reduction in the risk of adult obesity and cancer.

描述（由申请人提供）：肥胖和体力活动与多种癌症的风险降低和结局改善相关。在美国，随着儿童年龄的增长，儿童肥胖症正在增加，而身体活动水平却在下降。由于两者都强烈地跟踪到成年期，因此成年后肥胖和可能的癌症的风险增加。因此，在美国，预防儿童肥胖和改善身体活动已被选为主要的公共卫生目标，以减少肥胖和癌症的风险和后遗症。步行上学是2010年健康人群的一项国家健康目标，也符合美国癌症协会对儿童每天至少进行60分钟中度至剧烈体育活动的建议。步行上学与每天24-40分钟的中等到剧烈的身体活动有关。增加儿童步行活动可能会增加受伤的风险;然而，与成年人一起步行将这种风险降低了近70%。步行校车（WSB）通过提供由几个负责任的成年人监督的一段时间的身体活动和在往返学校的路上围绕行人安全技能的教学机会来解决身体活动和安全问题。缺乏关于WSB对儿童上学交通方式、行人安全、日常体力活动和健康影响的随机对照研究。我们努力帮助填补这一重要空白。这项研究计划的目标将是1）确定学生参与WSB的社会人口统计学预测因素，2）评估WSB计划的影响，以减少父母让孩子步行上学和放学的障碍，增加行人安全行为，增加步行上学，增加每日中度到剧烈的身体活动，并减少四年级学生的体重增加，3）获得与家长志愿者一起实施WSB计划的经验，并确定家长的可接受性和参与度。我们的具体目标包括：（1）对四年级学生及其家长进行纵向队列研究，以确定与社会人口学数据相关的WSB参与预测因素;（2）从4所公立小学成功招募30名儿童（n=120）参加WSB干预试点，并进行4-一项为期一个月的试点组随机对照试验，评估其在减少父母认为的允许孩子步行上学和放学的障碍，增加孩子步行上学，增加儿童行人安全行为，增加日常中度到剧烈的身体活动，并减少四年级学生的体重增加;（3）进行为期4个月的可行性试验的WSB计划由家长志愿者，收集过程数据，并进行半结构化的定性采访家长的可接受性。公共卫生关系：步行校车（WSB）的目的是增加学生步行上学和放学，行人安全，身体活动，并减少体重增加。WSB将提供一种有针对性的、基于人口的方法，以解决儿童缺乏身体活动和儿童肥胖症流行的问题。这反过来又会导致成人肥胖和癌症风险的大幅降低。
