DESCRIPTION (provided by applicant): The extent and nature of psychosocial adjustment in obese youth is poorly understood with mixed findings reported in the literature. Scant efforts have been made to examine this dynamic sequence over time with a statistically sound analysis to capture the direction of time-based causal influence as well as growth trajectories of both obesity and adjustment problems. Relatively little information is available about the linkage of dynamic changes of weight status to the developmental course of co-occurring adjustment problems during adolescence. In response to the NICHD program announcement of Secondary Data Analysis Based on NICHD Study of Early Child Care and Youth Development (SECCYD) (PA-06-284), we propose to conduct a secondary data analysis of the NICHD SECCYD data to investigate time-based causal processes of dynamic changes of weight status and individual and co-occurring domains of psychosocial adjustment just prior to and during the pubertal transition, that is, from 3rd grade (about age 9) to age 15. We apply state of the art and the novel modeling approaches of latent growth curve models and dynamic models of latent difference score to (1) describe the shapes of growth curves for weight status and individual domains of psychosocial adjustment including depression, broad-band behavior problems (i.e. internalizing and externalizing problems) and narrow- band syndrome subscales (i.e. withdrawn, somatic complaints, anxious/depressed, social problems, thought problems, attention problems, delinquent behavior, and aggressive behavior) during the period from 3rd grade (about age nine) to age fifteen; (2) delineate the time-based cross-lagged causal influences of weight status and individual domains of psychosocial adjustment including depression, broad- and narrow-band behavior problems; (3) examine the linkage of dynamic changes of weight status to the development course of co- occurring multiple domains of psychological adjustment; (4) investigate effects of an array of selected possible moderators on the dynamic interrelations between obesity and behavioral problems by comparing growth and changes related to potentially different group dynamics, including characteristics from adolescents themselves (gender, ethnicity, pubertal timing, obesity status and early behavioral problems prior to 3rd grade (about age nine), and growth trajectory patterns of weight status during the transition period from 3rd grade to age 15), family (parental support) and peers (peer support) characteristics. Findings of this study will have the great potential to advance knowledge on associations between obesity and psychosocial adjustment during adolescence, which can be translated into appropriate interventions to address the epidemic of obesity in adolescents. PUBLIC HEALTH RELEVANCE: Over 15% of U.S. adolescents are considered obese. The proposed study will advance our understanding of the dynamic causal sequence of obesity with psychosocial adjustment during pubertal transition, which will have important implication in public health for improving the physical development and mental well-being of adolescents.

描述（由申请人提供）：人们对肥胖青少年心理社会调整的程度和性质知之甚少，文献报道的结果好坏参半。人们很少努力通过统计上合理的分析来检查这种随时间变化的动态序列，以捕获基于时间的因果影响的方向以及肥胖和调整问题的增长轨迹。关于体重状况的动态变化与青春期同时发生的调整问题的发展过程之间的联系的信息相对较少。为了响应 NICHD 计划宣布的基于 NICHD 早期儿童保育和青少年发展研究 (SECCYD) 的二次数据分析 (PA-06-284)，我们建议对 NICHD SECCYD 数据进行二次数据分析，以调查青春期过渡之前和期间（即从三年级（大约 9岁）到15岁。我们应用潜在生长曲线模型和潜在差异评分动态模型的最新建模方法来（1）描述体重状态的生长曲线形状和心理社会调整的各个领域，包括抑郁、宽带行为问题（即内化和外化问题）和窄带综合征子量表（即孤僻、躯体投诉、焦虑/抑郁、社会问题、思想问题、注意力） 三年级（约九岁）至十五岁期间的问题、犯罪行为和攻击行为； (2) 描述体重状况和心理社会调整的各个领域（包括抑郁、宽带和窄带行为问题）的基于时间的交叉滞后因果影响； （3）考察体重状况的动态变化与同时发生的多个心理调节领域发展过程的联系； (4) 通过比较与潜在不同群体动态相关的生长和变化，研究一系列选定的可能调节因素对肥胖和行为问题之间动态相互关系的影响，包括青少年本身的特征（性别、种族、青春期时间、肥胖状况和三年级之前（大约九岁）的早期行为问题，以及从三年级到 15 岁过渡期间体重状态的增长轨迹模式）、家庭 （父母支持）和同伴（同伴支持）特征。这项研究的结果将具有巨大的潜力，可以增进对青春期肥胖与心理社会调整之间关系的了解，这可以转化为适当的干预措施，以解决青少年肥胖的流行问题。 公共卫生相关性：超过 15% 的美国青少年被认为肥胖。这项研究将增进我们对青春期过渡期间肥胖与心理社会调整的动态因果序列的理解，这将对改善青少年的身体发育和心理健康的公共卫生产生重要影响。
