The objective of this study was to investigate how perceptions of weight by children themselves, parents, and health professionals influence children's persistent attempts to lose weight.
The sample included 4,914 children aged 8 to 15 years from the 2005 to 2014 National Health and Nutrition Examination Survey (representing 20.7 million children). Data were analyzed using logistic regression models.
About 34.2% never made an effort to lose weight, whereas 28.2% made persistent attempts to lose weight. Children's persistent attempts to lose weight were highly related to their own BMI percentile. Children's self-perceptions of overweight increased the odds of persistent attempts to lose weight more than sevenfold. Health professionals' perceptions that children were overweight increased the odds of persistent attempts to lose weight almost threefold. However, parents' perceptions of children as overweight had a relatively small though significant influence on children's attempts to lose weight.
As perceptions of children's weight status play big roles in children's attempts to lose weight, interventions focusing on increasing accuracy of perceptions may help promote healthy weight loss efforts. Although parents are key agents in controlling their children's weight gain, especially among minority school-aged children, the study findings also emphasize the greater importance of health professionals on children's attempts to lose weight across different racial/ethnic groups.
本研究旨在探讨儿童自身、家长和健康专业人员对体重的看法如何影响儿童持续减肥的努力。
该样本包括来自 2005 年至 2014 年全国健康和营养调查（代表 2070 万儿童）的 4914 名 8 至 15 岁的儿童。数据分析采用逻辑回归模型。
约 34.2%的儿童从未试图减肥，而 28.2%的儿童持续努力减肥。儿童持续减肥的努力与自身 BMI 百分位高度相关。儿童对超重的自我认知增加了持续减肥的可能性超过七倍。健康专业人员认为儿童超重增加了持续减肥的可能性几乎三倍。然而，家长对孩子超重的看法对孩子减肥的努力有相对较小但显著的影响。
由于对儿童体重状况的看法在儿童减肥努力中起着重要作用，因此关注提高看法准确性的干预措施可能有助于促进健康的减肥努力。尽管父母是控制孩子体重增加的关键因素，尤其是在少数族裔学龄儿童中，但研究结果还强调了健康专业人员对不同种族/族裔群体儿童减肥努力的更大影响。
