This research will examine cross-sectional and prospective predictors of adolescent obesity using a social-ecological framework. We will recruit 420 youth and one of their parents from an existing cohort of youth who are currently participating in the Minnesota Adolescent Community Cohort (MACC) study. The MACC cohort is a representative sample, drawn from 60 geopolitical units throughout the state of Minnesota, and has been followed for 4 years as part of a study examining the effects of state and local tobacco programs on youth tobacco use. Dr. Jean Forster is the Principal Investigator for this on-going study. For our TREC research, we will invite students in the MACC cohort who are 15-16 years old and live in the metro area of Minneapolis and St. Paul to be involved in this study of the etiologic factors of obesity in adolescents. We will assess potential obesogenic factors at the individual, family, school and community level by collecting data at three time points over a period of 24 months. Individual measures will include anthropometry and a variety of psychosocial, preference and behavioral assessments related to eating and activity. Family measures will include family socioeconomic status, parent weight and body composition, family meal and activity patterns, and the home food and activity environments. School level measures will include opportunities for physical activity, competitive foods, and school food and activity policies. Community-level measures will include the use of Geographical Information System (CIS) to assess obesogenic environmental factors such as the presence of walking and bike paths, convenience stores, and fast food restaurants. This research is multidisciplinary involving researchers from across four departments at the University of Minnesota (the Division of Epidemiology, School of Nursing, School of Kinesiology, and the College of Architecture and Landscape Architecture) and including scientists with a expertise in the biological sciences, exercise physiology, nutrition, the behavioral sciences, psychology, and urban planning. This research proposal is intended to be the first in a series of proposals that will include following the cohort into young adulthood to assess obesity risk and related cancers, help in directing the focus of future interventions to prevent the onset of childhood overweight and obesity in order to reduce chronic disease risk.

这项研究将使用社会生态框架检查青少年肥胖的横截面和前瞻性预测指标。我们将招募420名青年和他们的一名父母来自现有的一群青年队，他们目前正在参加明尼苏达州青少年社区队列（MACC）研究。 MACC队列是一个代表性的样本，由明尼苏达州的60个地缘政治单位绘制，并且在研究州和地方烟草计划对青年烟草使用的影响方面已有4年的遵循4年。让·福斯特（Jean Forster）博士是这项正在进行的研究的主要研究者。对于我们的TREC研究，我们将邀请15-16岁的MACC队列学生居住在明尼阿波利斯的都会区 和圣保罗参与了青少年肥胖症的病因学因素。我们将通过在24个月的时间内在三个时间点收集数据来评估个人，家庭，学校和社区层面的潜在肥胖因素。个人措施将包括人体测量法以及与饮食和活动有关的各种社会心理，偏好和行为评估。家庭措施将包括家庭社会经济状况，父母体重和身体成分，家庭用餐和活动方式以及家庭食品和活动环境。学校级别的措施将包括体育锻炼，竞争食品以及学校食品和活动政策的机会。社区级措施将包括 使用地理信息系统（CIS）评估肥胖环境因素，例如步行和自行车道，便利店和快餐店的存在。这项研究是跨学科的，涉及明尼苏达大学四个系的研究人员（流行病学科，护理学系，运动机能学和建筑与景观建筑学院），包括具有生理学，运动生理学，营养，营养，行为科学，心理学，心理学和URBARCHERICAL和URBAL SCLENALIGY和URECLAL CAPICALICAL，营养学和IRBARCION和URESCOLICAL，营养学的科学知识的科学家。该研究建议旨在成为一系列建议中的第一个提案，其中包括遵循队列的成年后，以评估肥胖风险和相关癌症，有助于指导未来的干预措施以防止儿童超重和肥胖的发作，以减少慢性疾病风险。
