EARLY DIETING IN GIRLS

描述：拟议项目的总体目标是绘制 制定控制女孩食物摄入量的措施， 注意在童年中期开始节食。 调查 有证据表明，在10岁之前， 发生在青春期，超过一半的女孩报告害怕肥胖 并通过节食来保持苗条的身材。 的研究热点 对女孩的影响，因为节食的发生率是有据可查的， 女性高于男性，且性别差异明显 儿童：虽然男孩和女孩都希望避免肥胖， 通常渴望变得更大，更高，更强壮，所以尝试 饮食限制在男孩中很少见。 研究人员先前对控制食物摄入量的研究， 幼儿被用来作为一个出发点，调查 在控制食物摄入方面的发展变化 童年中期 根据初步数据， 调节父母的儿童喂养方法的能量摄入， 父母节食，特别注意的是， 女儿对能量摄入、食物摄入和偏好的调节， 早期节食身体形象和肥胖 家族因素包括 父母的饮食史，父母的食物摄入和偏好， 肥胖和父母对孩子饮食的控制。 纵向 170名女孩及其父母的数据将在这些女孩 六岁，八岁，十岁。 多元回归与结构方程 将使用模型来检验家庭变量之间的关系; 同伴和媒体的影响;以及女孩对能量摄入的调节， 节食的身体形象，食物偏好和食物摄入模式。 聚类分析将用于探索不同的摄入方式 女孩之间的控制，以及这些风格是否在相对风险方面有所不同 节食的 调查报告称，年轻女孩节食的发生率令人担忧， 关于体重控制策略， 在这个年龄组中构成节食，这项研究将获得 关于这一点的信息。 这项研究将产生新的和必要的 关于节食的病因学和个人出现的数据 控制食物摄入的差异。 此外该 研究人员将提出并测试家庭影响的途径， 饮食行为和肥胖症的影响可以代代相传 通过行为的影响。 这些证据对于防止或 减少节食的发生率和对健康的负面影响 与这种节食有关。

DESCRIPTION: The general aim of the proposed project is to chart the development of the controls of food intake among girls, with particular attention to the onset of dieting during middle childhood. Survey evidence reveals that by the age of 10, prior to the fat deposition that occurs during puberty, well over half of girls report fear of fatness and engage in dieting to attain a thin body shape. The research focuses on girls because the incidence of dieting is well documented to be much higher among women than men, and the sex difference is apparent among children: while boys and girls alike wish to avoid being fat, boys typically aspire to be bigger, taller, and more muscular, so attempts at dietary restriction are rare among boys. The investigators' prior research on the controls of food intake among young children is used as a point of departure to investigate developmental changes in the controls of food intake among girls during middle childhood. Based on preliminary data linking children's regulation of energy intake to parents' child feeding practices and parental dieting, special attention is given to familial antecedents of daughters' regulation of energy intake, food intake and preferences, early dieting, body image, and adiposity. Familial factors include parental dieting history, parental food intake and preferences, adiposity, and parental control over children's eating. Longitudinal data on 170 girls and their parents will be obtained when the girls are 6, 8, and 10 years old. Multiple regression and structural equation modeling will be used to test relationships among familial variables; peer and media influence; and girls' regulation of energy intake, onset of dieting body image, food preferences and food intake patterns. Cluster analysis will be used to explore differing styles of intake control among girls, and whether these styles differ in relative risk for dieting. Surveys report an alarming incidence of dieting among young girls, but there is little evidence regarding the weight control strategies that constitute dieting among this age group, and this research will obtain information on this point. This research will yield new and essential data on the etiology of dieting and the emergence of individual differences in the controls of food intake. In addition, the researchers will propose and test pathways by which familial influence on eating behavior and adiposity can be transmitted across generations via behavioral influence. Such evidence is essential in preventing or reducing the incidence of dieting, and the negative health consequences associated with such dieting.
