DESCRIPTION (provided by applicant): Overall Objective: The overall aim of this study is to develop and test a theory-based guided imagery lifestyle intervention to reduce risk factors for type 2 diabetes and cardiovascular disease in overweight Latino adolescents. Overall Hypothesis: Guided imagery lifestyle intervention will be more effective than nutrition education alone in decreasing risk factors for type 2 diabetes and cardiovascular disease, and in increasing health-promoting dietary and physical activity behaviors. Specific Aims and Approach: Specific Aim 1: To develop a guided imagery intervention program based on stress reduction and on the Theory of Meanings of Behavior for use with overweight Latino adolescents. Specific Aim 2: To conduct a randomized and controlled trial to test the direct and mediated effects of adding a guided imagery intervention program to a nutrition education program in overweight Latino adolescents. Major outcomes will include insulin sensitivity, psychosocial measures, and dietary and physical activity behaviors. Rationale: Prevalence of obesity and type 2 diabetes is increasing in overweight youth, especially in ethnic minorities. 28% of overweight Latino adolescents with a family history of type 2 diabetes have impaired glucose tolerance (IGT), and 30% have the metabolic syndrome. There is a critical need to develop innovative and effective lifestyle interventions to reduce insulin resistance and overweight in this population at risk. Research Design & Methods: Using focus group qualitative methods, a 12-week guided imagery intervention program will be developed that is culturally and developmentally appropriate for overweight Latino adolescents. This intervention will then be tested in a randomized, controlled trial. Outcome assessments will include physiologic measures (insulin sensitivity, body composition, cortisol secretion), psychosocial measures (perceived stress, emotional eating, meanings of eating and physical activity), and behavioral measures (dietary intake and physical activity). Health implications: Guided imagery holds particular promise to reduce chronic disease risk factors in overweight adolescents by reducing chronic stress and transforming unhealthful dietary and physical activity behaviors. This could be an effective means of preventing both type 2 diabetes and cardiovascular disease in susceptible youth, thereby reducing both the suffering and costs associated with these diseases.

描述（由申请人提供）： 总体目标：本研究的总体目标是开发和测试基于理论的意象生活方式干预措施，以减少超重拉丁裔青少年 2 型糖尿病和心血管疾病的危险因素。总体假设：在减少 2 型糖尿病和心血管疾病的危险因素以及增加促进健康的饮食和身体活动行为方面，引导意象生活方式干预比单独的营养教育更有效。具体目标和方法： 具体目标 1：制定基于减压和行为意义理论的引导意象干预计划，用于超重的拉丁裔青少年。具体目标 2：进行一项随机对照试验，以测试在超重拉丁裔青少年的营养教育计划中添加引导意象干预计划的直接和中介效果。主要结果包括胰岛素敏感性、心理社会测量以及饮食和身体活动行为。理由：肥胖和 2 型糖尿病在超重青少年中的患病率正在增加，尤其是在少数族裔中。 28% 有 2 型糖尿病家族史的超重拉丁裔青少年患有糖耐量受损 (IGT)，30% 患有代谢综合征。迫切需要开发创新且有效的生活方式干预措施，以减少高危人群的胰岛素抵抗和超重。研究设计和方法：使用焦点小组定性方法，将制定为期 12 周的意象引导干预计划，该计划在文化和发展上适合超重的拉丁裔青少年。然后将在随机对照试验中测试这种干预措施。结果评估将包括生理测量（胰岛素敏感性、身体成分、皮质醇分泌）、心理社会测量（感知压力、情绪化饮食、饮食的意义和身体活动）和行为测量（饮食摄入和身体活动）。健康影响：引导意象特别有希望通过减少慢性压力和改变不健康的饮食和身体活动行为来减少超重青少年的慢性疾病危险因素。这可能是预防易感青少年患 2 型糖尿病和心血管疾病的有效方法，从而减少与这些疾病相关的痛苦和费用。
