项目摘要

DESCRIPTION (provided by applicant): This project will develop and evaluate a theory-based behavioral intervention to modify diet and physical activity and reduce risk for obesity, cancer and other chronic diseases in children aged 10 to 12 years recruited through a managed care setting. Managed care provides an ideal setting for reaching families and for disseminating effective obesity prevention programs. The development of the intervention will be completed using established theories in health behavior (e.g., Social Cognitive Theory, Self-Determination Theory), research on the predictors of diet and physical activity in children, and knowledge gleaned from prior tailored print intervention studies. Intervention components will be developed over a 9-month period and will receive targeted testing during development. The OPT for Health II intervention will be evaluated using a randomized experimental design in which families (N=400) will be recruited from the KPSC membership database, matched on single or dual parent household status and number of children living in the home, and randomly assigned to the OPT for Health II intervention condition or a usual care control condition. Families in the control condition will receive usual care in the KPSC system which includes notification and access to classes on diet, physical activity and weight control. Randomization of families will occur after the baseline assessment is completed to eliminate measurement bias based on treatment assignment. Measures of diet, physical activity, psychosocial mediators, height and weight (Body Mass Index) will be completed on the recruited target parent and child in each family. Assessments will occur at clinic sites of KPSC, a major health maintenance organization in Southern California and will be completed by trained interviewers. The OPT for Health II intervention will include (a) one meeting between the participating families and a health educator using MI principles to motivate families for change, to select an initial behavior to change, and to develop an action plan, (b) four tailored newsletters (2 for diet, 2 for physical activity) for parents and four tailored newsletters for the target children that are also culturally targeted (Hispanic, Non-Hispanic), (c) two family activities (1 for diet, 1 for physical activity) for both parents and children with instructions included as part of the tailored newsletters, and (d) five Motivational Interviewing telephone calls (2 diet, 2 physical activity, 1 summary) for parents. These intervention operations have been tested for feasibility and for initial efficacy estimates using R21 funding from the National Cancer Institute (1R21CA95016). In OPT for Health II, recruitment will occur over a 20 month period using a rolling recruitment and intervention strategy. Five families will be recruited weekly with baseline assessment completed shortly after recruitment. Randomization to conditions will then occur and the intervention will be delivered over a 24-week period (6 months). Follow-up assessments will occur at 6- and 12-months post-baseline and will provide outcome measures and measures of potential mediators for observed changes in diet, physical activity and BMI. Two 24-hour recalls will be completed at each assessment period. BMI and physical activity will be objectively measured through height and weight assessments, and through the use of accelerometry to assess physical activity.

描述（由申请人提供）：该项目将开发和评估基于理论的行为干预措施，以修改饮食和体育锻炼，并减少10至12岁儿童的肥胖，癌症和其他慢性疾病的风险，这些疾病是通过托管护理环境招募的。托管护理提供了一个理想的环境，可供接近家庭和传播有效的肥胖预防计划。干预措施的发展将使用既定的健康行为理论（例如社会认知理论，自决理论），儿童饮食和体育锻炼的预测因素以及先前量身定制的印刷干预研究收集的知识来完成。干预组件将在9个月的时间内开发，并将在开发过程中接受针对性的测试。将使用随机实验设计评估选择健康II干预措施，该设计将从KPSC成员数据库中招募家庭（n = 400），以单亲或双父家庭状态和居住在家庭中的儿童数量进行匹配，并随机分配给OPT的健康II干预条件或常规护理控制条件。处于控制条件的家庭将在KPSC系统中接受常规护理，其中包括通知和饮食，体育锻炼和体重控制的课程。在完成基线评估后，将发生家庭的随机化，以消除基于治疗分配的测量偏差。饮食，体育锻炼，社会心理介体，身高和体重（体重指数）的度量将在每个家庭的招聘目标父母和孩子上完成。评估将在南加州的主要健康维护组织KPSC的诊所进行，并将由训练有素的访调员完成。 The OPT for Health II intervention will include (a) one meeting between the participating families and a health educator using MI principles to motivate families for change, to select an initial behavior to change, and to develop an action plan, (b) four tailored newsletters (2 for diet, 2 for physical activity) for parents and four tailored newsletters for the target children that are also culturally targeted (Hispanic, Non-Hispanic), (c) two family activities (1 for diet, 1 for体育锻炼）适用于量身定制的新闻通讯的一部分的父母和孩子都包含指导，以及（d）五个动机采访电话（2次饮食，2个饮食，2个体育活动，1个摘要）。这些干预操作已通过国家癌症研究所的R21资金（1R21CA95016）测试了可行性和初始疗效估算。在选择健康II中，将使用滚动招聘和干预策略在20个月内进行招聘。招募后不久，将完成五个家庭，每周招募基线评估。然后将发生随机分配给条件，干预将在24周（6个月）内进行。后续评估将在6个月和12个月后进行，并将为观察到的饮食，体育活动和BMI的变化提供结果指标和衡量标准。在每个评估期间，将完成两个24小时的召回。 BMI和体育锻炼将通过身高和体重评估以及使用加速度测定法来客观地衡量。
