身体形象似乎介导肥胖和健康行为以及体重控制尝试之间的关联。我们通过人口统计学特征研究了儿童身体意象的分布，以及它们与饮食、运动和体重变化的相关性。在2000 - 2011年期间，使用混合模型对2000 - 2011年中国健康全国调查中的6- 17岁儿童的基线和随访时的儿童身体形象和健康行为进行了评估。儿童的实际体重状况（超重：16.9%）与自我评价的身体形象（2011年脂肪：2.4%）之间存在很大差异。不到1%的儿童希望拥有肥胖的身体;女孩比男孩更希望变瘦（52.5%比40.9%）。大约11%的儿童需要减肥才能达到他们想要的基线。在随访期间，那些需要减肥的人更有可能尝试节食来改变体重（OR，95% CI = 1.9，男孩1.1-3.5;女孩1.7，1.1-2.5），并且不太可能感到他们有足够的体力活动（OR，95%CI = 0.5，男孩0.4-0.7;女孩0.6，0.5-0.9），尽管他们的体重增加显著高于那些具有一致自我和期望身体形象的人（男孩β[SE] = 0.4[0.1];女孩0.2[0.1]，所有p <0.05）。体像差异对超重儿童后续健康行为的影响无显著性差异。在中国非超重儿童中，自我与期望身体意象的差异促使儿童改变与肥胖相关的健康行为。
Body image seems to mediate the association between obesity and health behaviors as well as weight control attempts. We examined the distribution of children’s body image by demographic characteristics and their subsequent associations with eating, exercise, and weight change. Child body image and health behaviors from the China Health National Survey 2000–2011 were assessed at baseline and in follow-up for 6- to 17-year-old children during 2000–2011 using mixed models. There was a large discrepancy between children’s actual weight status (overweight: 16.9%) vs. self-rated body image (fat: 2.4% in 2011). Less than 1% of children desired a fat body; girls were more likely to want to be thin (52.5% vs. 40.9%) than boys. About 11% of children needed to lose weight in order to be at their desired baseline. During follow-up, those needing weight loss to be as desired were more likely to attempt dieting to change their weight (OR, 95% CI = 1.9, 1.1–3.5 in boys; 1.7, 1.1–2.5 in girls) and less likely to feel they had enough physical activity (OR, 95% CI = 0.5, 0.4–0.7 in boys; 0.6, 0.5–0.9 in girls), although their weight gain had been significantly higher than those having consistent self and desired body images (β[SE] = 0.4[0.1] in boys; 0.2[0.1] in girls, all p <0.05). However, no significant difference was shown in subsequent health behaviors among overweight children by body image discrepancy. The discrepancy in self vs. desired body image motivated children to change their obesity-related health behaviors among non-overweight children in China.
