PROJECT SUMMARY/ABSTRACT Hispanic adolescents in the United States are disproportionately affected by obesity compared to their non- Hispanic White adolescent counterparts. A recommended means of addressing adolescent obesity is through participation in family-based multicomponent behavioral interventions (targeting improvements in family functioning as a mechanism of change). Although family-based interventions (FBIs) exist, effects on adolescent obesity-related outcomes, especially among Hispanic adolescents, are small or insignificant. Limited effects may be due to gaps in the existing research: 1) few FBIs have incorporated obesity-related socioecological factors at multiple levels as tailoring variables to improve intervention effects, 2) FBIs often overlook fathers and other household members (such as grandparents in multi-generational households) that may also play a role on adolescents’ obesity risk behaviors, and 3) FBIs often assess family functioning retrospectively without consideration of day-to-day family dynamics, which may also influence obesity risk behaviors. Thus, I propose the following aims to address existing gaps: 1) conduct secondary data analysis using five waves of data from the Adolescent Brain Cognitive Development study and the Hispanic adolescent subsample (n=2411, Mage=9.5 at baseline) to examine the direct and moderating effects of factors at each level of the socioecological model on the longitudinal trajectories of obesity risk behaviors/obesity status, 2) pilot an EMA protocol with Hispanic adolescents (9-to-17 years) and household caregivers (n=20 family units) across 7 days to assess feasibility and acceptability, identify barriers and facilitators to completion of daily assessments by family units, and make needed modifications to the EMA protocol, and 3) implement a finalized EMA protocol over a 6-month period, using measurement burst design, and assess the effects of momentary changes in family functioning behaviors and associations with daily physical activity, sleep, and nutrition behaviors (n=50 family units, adolescents 9-to-17 years). The purpose of this training application is to gain mentoring and training in the following four areas: 1) intensive longitudinal data analysis, 2) recruitment, retention, and implementation, 3) innovative assessment design, and 4) professional development. Under the mentorship of a team of interdisciplinary researchers, experts in either obesity prevention, longitudinal data analysis, ecological momentary assessment, and/or minority health, Dr. Fernandez will successfully complete the plan of research at the University of Texas Health Science Center at Houston, School of Public Health and attain preliminary data to inform the development of a NIH-R01 proposal.

项目概要/摘要 与非裔美国人相比，美国的西班牙裔青少年受到肥胖的影响更大。 西班牙裔白人青少年少数群体是解决青少年肥胖问题的推荐方法。 参与基于家庭的多成分行为干预措施（旨在改善家庭 尽管存在基于家庭的干预措施（FBI），但仍会产生影响。 青少年肥胖相关的结果，尤其是西班牙裔青少年，很小或微不足道。 有限的影响可能是由于现有研究的空白：1）很少有联邦调查局将肥胖相关问题纳入研究范围。 多个层面的社会生态因素作为调整变量以提高干预效果，2) FBI 经常 忽视父亲和其他家庭成员（例如多代家庭中的祖父母） 也可能对青少年的肥胖风险行为产生影响，3) 联邦调查局经常评估家庭功能 回顾性地不考虑日常家庭动态，这也可能影响肥胖风险 因此，我提出以下目标来解决现有差距：1）进行二次数据分析。 使用来自青少年大脑认知发展研究和西班牙裔青少年的五波数据 子样本（n=2411，基线时 Mage=9.5），用于检查每个级别因素的直接影响和调节影响 肥胖风险行为/肥胖状态纵向轨迹的社会生态学模型，2）试点 与西班牙裔青少年（9 至 17 岁）和家庭看护者（n = 20 个家庭单位）的 EMA 协议涵盖 7 个国家 评估可行性和可接受性，确定完成日常评估的障碍和促进因素的天数 以家庭为单位，并对 EMA 协议进行必要的修改，以及 3) 实施最终确定的 EMA 使用测量突发设计，在 6 个月的时间内完成协议，并评估瞬时的影响 家庭功能行为的变化以及与日常身体活动、睡眠和营养的关系 行为（n = 50 个家庭单位，9 至 17 岁的青少年）。 以下四个领域的指导和培训：1）纵向密集数据分析，2）招聘， 保留、实施和实施，3) 创新的评估设计，以及 4) 专业发展。 由跨学科研究人员、肥胖预防专家、纵向数据专家组成的团队的指导 分析、生态瞬时评估和/或少数民族健康，费尔南德斯博士将成功完成 德克萨斯大学休斯顿健康科学中心、公共卫生学院的研究计划 获取初步数据，为 NIH-R01 提案的制定提供信息。
