EARLY DIETING IN GIRLS

描述：(研究人员摘要)这项竞争性延续拨款 建议提供5年资金，以继续进行前瞻性纵向研究 发展对食物摄入量的行为控制，重点是节食，以及 同时出现能量平衡问题(超重、肥胖和 饮食失调)在女孩中。192个女孩从很久以前就被纵向跟踪了 5到9年，这项申请计划持续到11、13和15年 多年来，能量平衡问题在女孩中普遍存在。超重， 肥胖和长期节食在美国已经达到流行的比例， 对青春期女孩的健康构成重大威胁，包括 心血管疾病、非胰岛素依赖型糖尿病、癌症、抑郁症和自卑。具体目标是 不变：1)刻画女孩之间的个体差异 儿童进食量和体重状态行为控制的研究进展 从童年中期到青春期中期。2)确定家族性预测因素 女孩在食物摄入行为控制上的个体差异 以及体重状况。调查人员建议使用纵向数据来 评估父母体重状况、节食等对家庭的影响 儿童时期确定的历史和儿童喂养策略可以预测 青春期饮食和体重模式的差异。这样的信息是 在设计有效的预防干预措施以解决 女孩超重、长期节食和体重问题的流行水平 还有女人。3)获得关于女孩在做什么的描述数据 报告节食。女孩们报告说她们在节食，但具体的体重控制 所使用的策略可能对健康有非常不同的影响；例如， 正在节食的女孩吃更多的水果和蔬菜，或者使用泻药和 禁食？

DESCRIPTION: (investigator's abstract) This competitive continuation grant proposes 5 years of funding to continue the prospective longitudinal study of the developing behavioral controls of food intake, with a focus on dieting, and concurrent emergence of problems of energy balance (overweight, obesity, and eating disorders) among girls. 192 girls were followed longitudinally from ages 5 to 9 years, and this application proposes to continue through 11, 13, and 15 years, when problems of energy balance are pervasive among girls. Overweight, obesity, and chronic dieting have reached epidemic proportion in the US and pose major threats to adolescent girls' health, including elevated risk for CVD, NIDDM, cancer, depression, and low self-esteem. Specific aims are unchanged: 1) to characterize individual differences among girls in the development of the behavioral controls of food intake and weight status from middle childhood through middle adolescence. 2) To identify familial predictors of individual differences among girls in the behavioral controls of food intake and weight status. The investigators propose to use longitudinal data to evaluate whether familial influences such as parents' weight status, dieting history and child feeding strategies identified in childhood predict differences in eating and weight patterns into adolescence. Such information is essential in designing effective preventive interventions to address the epidemic levels of overweight, chronic dieting and weight concerns among girls and women. 3) To obtain descriptive data on what girls are doing when they report dieting. Girls report that they are dieting, but specific weight control strategies used can have very different implications for health; for example, are dieting girls eating more fruits and vegetables, or using purgatives and fasting?
