The current study tested a longitudinal model predicting the emergence of dieting in girls (n = 183) at age 9 years using data from the same girls measured at ages 5 and 7.
Variables related to the girls' weight status, psychological health, body satisfaction, maternal child feeding practices, and family environment are included in a hierarchical regression model predicting the emergence of dieting in girls. Interactions of girls' weight status with other variables in the model are also included in the last step.
Results indicate that the model accounts for 45% of the variance in the outcome scores and that variables across constructs have significant contributions to the model. Results also show that girls' weight status, both independently and as an interaction term, accounts for a large proportion of variance in this model.
Weight status at age 5 years is a critical factor related to the emergence of dieting in young girls.
本研究使用来自183名女孩在5岁和7岁时的测量数据,测试了一个纵向模型,该模型用于预测9岁女孩节食行为的出现。
与女孩体重状况、心理健康、身体满意度、母亲的育儿喂养方式以及家庭环境相关的变量被纳入一个分层回归模型,该模型用于预测女孩节食行为的出现。模型中女孩体重状况与其他变量的交互作用也包含在最后一步。
结果表明,该模型解释了结果分数中45%的方差,并且不同构念的变量对模型有显著贡献。结果还表明,女孩的体重状况,无论是单独还是作为交互项,在该模型中都占了很大比例的方差。
5岁时的体重状况是与年轻女孩节食行为出现相关的一个关键因素。
