A Community-Academic Partnership to Address Disparities in Obesity Among Youth

描述（由申请人提供）：正如2010年《健康人群》所述，消除健康差距，特别是儿童肥胖，是美国的一个主要目标。在拟议研究的社区合作伙伴洛杉矶联合学区（LAUSD），该地区43%的小学和中学儿童肥胖或超重，拉丁美洲人（45%）和黑人（41%）的患病率最高，而白人（29%）和亚洲人/太平洋岛民（27%）。有限的体育活动和不良的饮食习惯导致所有种族/族裔群体的青年肥胖，特别是黑人和拉丁美洲人。我们提出了一项为期5年的随机对照试验，以学校为基础的肥胖预防干预，以解决种族/民族的差异，在LAUSD的中学生营养和体育活动。我们的目标是：（1）确定以学校为基础的社区参与式研究干预是否可以增加健康饮食，体育活动和身体健康，并减少久坐行为;（2）检查干预有效性的种族和民族差异;（3）评估理论上重要的行为变化相关因素（即，态度、社会规范和自我效能）预测干预目标行为的变化;（4）估计干预的成本和收益，计算成本效益比;（5）向社区利益相关者传播干预结果，并制定广泛传播方案的计划。在根据NIH/NCMHD RFA-MD-05-002（R24 MD 001648; MA Schuster，PI）进行的规划补助金中，我们建立了新的关系，并加强了LAUSD社区合作伙伴之间的现有关系，主要利益相关者投资于洛杉矶县的青年和肥胖预防，以及青少年健康促进中心的研究人员。这种合作伙伴关系已成为一种强大而蓬勃发展的合作，促使我们开发、试点测试和完善我们新的基于学校的干预措施--学生营养和锻炼（SNaX）。SNaX结合改善学校的食品环境和学校范围内的多媒体促销活动，为7年级学生和他们的家长与课后俱乐部，其中同龄人的领导人被鼓励使用一种激励性的采访风格，以促进健康饮食和体育活动的家庭和同龄人。SNaX旨在通过增强青少年的权能，使其成为社区内变革的倡导者，减少健康饮食和体育活动方面的种族/民族差异。

DESCRIPTION (provided by applicant): As outlined in Healthy People 2010, eliminating health disparities, especially with respect to child obesity, is a major US goal. In the LA Unified School District (LAUSD), the community partner for the proposed research, 43% of elementary and secondary school children in the district are obese or overweight, with the highest prevalence among Latinos (45%) and Blacks (41%), compared to Whites (29%) and Asians/Pacific Islanders (27%). Limited physical activity and poor diet contribute to obesity among youth from all racial/ethnic groups, especially Blacks and Latinos. We propose a 5-year randomized controlled trial of a school-based obesity prevention intervention to address racial/ethnic disparities in nutrition and physical activity among middle school youth in LAUSD. We aim to: (1) determine whether a school-based community-based participatory research intervention can increase healthy eating, physical activity, and physical fitness, and decrease sedentary behavior; (2) examine racial and ethnic differences in the effectiveness of the intervention; (3) assess whether theoretically important correlates of behavioral change (i.e., attitudes, social norms, and self-efficacy) predict changes in the behaviors targeted by the intervention; (4) estimate the costs and benefits of the intervention and calculate cost-effectiveness ratios; and (5) disseminate intervention results to community stakeholders and develop a plan for broad program dissemination. In a Planning Grant conducted under NIH/NCMHD RFA-MD-05-002 (R24 MD001648; MA Schuster, PI), we established new relationships and strengthened existing relationships among community partners at LAUSD, key stakeholders invested in youth and obesity prevention from across LA County, and researchers at the Center for Adolescent Health Promotion. This partnership has become a strong and thriving collaboration that has led to our developing, pilot testing, and refining our new school-based intervention, Students for Nutrition and exercise (SNaX). SNaX combines improvements to the school food environment and school-wide multimedia promotions for 7th graders and their parents with an after-school club in which peer leaders are encouraged to use a motivational interviewing style to promote healthy eating and physical activity to family and peers. SNaX aims to reduce racial/ethnic disparities in healthy eating and physical activity by empowering adolescents to be advocates for change within their communities.
