Environmental and Family Influences on Adolescent Overweight

描述(由申请人提供) 项目摘要：农村地区建成环境对健康的影响研究不足，对农村建成环境对青少年超重的影响几乎一无所知。我们这项研究的首要目标是检查建筑环境对新英格兰北部以农村为主的社区青少年超重的影响。我们的多学科团队将使用定量和定性的方法对青少年超重的风险因素进行多层次的评估。我们将通过研究2567名青少年及其父母的既定队列来实现我们的目标，这些队列代表佛蒙特州和新罕布夏州26个稳定的、以农村为主的社区。当2002-2003年首次对8-13岁的青少年进行调查时，社区超重率从9.7%到34.1%不等，这表明社区一级的超重率存在很大差异。从2006年1月开始，将通过三次年度电话调查对这一群体的相关个人和家庭特征进行评估。我们将使用地理信息系统数据和现场地图，来描述每个社区的建成环境。社区层面的数据将包括对娱乐资源和食物(包括快餐)供应的评估，以及密度、多样性和设计的标准衡量标准。我们将使用人种学的方法来评估和描述我们的队列所在的每所学校内围绕体育活动和食物的“文化”。对多层次数据的评估将使我们能够调查个人和家庭特征如何与建筑环境相互作用，以影响青少年超重。我们的主要结果将是青少年超重(定义为身体质量指数(BMI)等于或大于性别特定BMI-年龄增长曲线的第95个百分位数。中间结果将包括青少年的体力活动水平和饮食摄入模式，包括高脂肪和高热量食物的消费。我们调查小组的多学科专业知识和成熟的队列的可用性确保了拟议工作的可行性、效率和成功。相关性：我们的研究包括儿童和低社会经济地位社区，这两个群体因其脆弱性而成为RFA-04-003的目标人群。此外，我们的研究侧重于农村社区，满足了对农村人口研究的明确需求。这项研究的结果将有助于确定可以通过特定干预措施针对的风险因素，以防止青少年超重。

DESCRIPTION (provided by applicant) Project Summary: The impact of the built environment on health in rural areas has been understudied and virtually nothing is known about the influence of the rural built environment on overweight in adolescents. Our overarching goal for this study is to examine the influence of the built environment on adolescent overweight in the predominantly rural communities of Northern New England. Our multidisciplinary team will use quantitative and qualitative methods to conduct multi-level assessments of risk factors for adolescent overweight. We will accomplish our aims by studying an established cohort of 2567 adolescents and their parents, representing 26 stable and largely rural communities in Vermont and New Hampshire. When adolescents (8-13 years of age) were first surveyed in 2002-2003, the prevalence of overweight by community ranged from 9.7% to 34.1%, indicating substantial variation at the community level. Relevant individual and family characteristics of this cohort will be assessed through three annual telephone surveys, beginning in January 2006. We will use GIS data and on-site mapping, to characterize the built environment of each community. The community level data will include assessments of recreational resources and food (including fast food) availability, as well as standard measures of density, diversity and design. We will use an ethnographic approach to assess and describe the 'culture' surrounding physical activity and food within each of the schools attended by our cohort. The assessment of multi-level data will allow us to investigate how individual and family characteristics interact with the built environment to influence adolescent overweight. Our primary outcome will be adolescent overweight (defined as body mass index (BMI) equal to or greater than the 95th percentile of the sex-specific BMI-for-age growth curves. Intermediate outcomes will include adolescent physical activity levels and dietary intake patterns, including consumption of high fat and high calorie foods. The multi-disciplinary expertise of our investigative group and the availability of a well-established cohort ensure the feasibility, efficiency, and success of the proposed effort. Relevance: Our study includes children and low SES communities, two populations targeted by RFA-04-003 because of their vulnerability. In addition, our study focuses on rural communities, meeting the expressed need for studies of rural populations. Results from this study will help to identify risk factors that could be targeted through specific interventions to prevent adolescent overweight.
