To investigate associations between sibling weight status, concerns about sibling weight, and parents' differential use of restrictive feeding practices.
Participants included 70 mother-father pairs with two biological children between 6 and 12 years old. Each parent completed three Child Feeding Questionnaire (CFQ) subscales (perception of child weight, concern about child weight, and restriction) for each participant sibling. Researchers measured heights and weights and converted child data into Body Mass Index percentiles (BMI%). Multiple regression analysis examined predictors of restrictive feeding practices used by both parents. The nature of differential treatment was examined by calculating Pearson's correlations among sibling differences (older minus younger sibling) in maternal and paternal CFQ reports and sibling BMI%.
Concern for child weight, but not actual child BMI% or parental perception of child weight, predicted restrictive feeding practices for both parents. Child gender was not related to child weight status, perception of child weight, concern for child weight, or restriction. Parents were more likely to use differential restrictive feeding practices when they had differential concern for the weight status of their children. However, this differential treatment was not related to differences in actual sibling BMI% or parental perception of child weight.
Parental concern for child weight, rather than actual child weight status, predicts restriction by both mothers and fathers. Across families, parents generally tend to use similar feeding practices with each of their children. Within families, parents may have different interactions with each sibling regarding food when differentially concerned about sibling weight status.
探讨兄弟姐妹的体重状况、对兄弟姐妹体重的担忧与父母在限制性喂养方式上的差异使用之间的关联。
研究对象包括70对父母，他们育有两名6至12岁的亲生孩子。每位父母针对每个参与研究的孩子完成三份儿童喂养问卷（CFQ）分量表（对孩子体重的认知、对孩子体重的担忧以及限制）。研究人员测量了孩子的身高和体重，并将数据转换为体重指数百分位数（BMI%）。多元回归分析检验了父母双方使用的限制性喂养方式的预测因素。通过计算母亲和父亲CFQ报告中兄弟姐妹差异（年长孩子减去年幼孩子）与兄弟姐妹BMI%之间的皮尔逊相关性，来研究差异对待的性质。
对孩子体重的担忧，而非孩子实际的BMI%或父母对孩子体重的认知，预测了父母双方的限制性喂养方式。孩子的性别与孩子的体重状况、对孩子体重的认知、对孩子体重的担忧或限制无关。当父母对孩子的体重状况有不同程度的担忧时，他们更有可能采用不同的限制性喂养方式。然而，这种差异对待与兄弟姐妹实际BMI%的差异或父母对孩子体重的认知无关。
父母对孩子体重的担忧，而非孩子实际的体重状况，预测了母亲和父亲的限制行为。在不同家庭中，父母通常倾向于对每个孩子采用相似的喂养方式。在家庭内部，当父母对兄弟姐妹的体重状况有不同程度的担忧时，他们与每个孩子在食物方面的互动可能会有所不同。
