Abstract: Objective To explore the effect of health education intervention measures on improving parents' perception of their children's weight, so as to provide scientific basis for intervention in preschool obese children. Methods Children from 7 kindergartens in Luohu district were randomly selected in this study in October 2020, and were divided into intervention group and control group. The intervention group consisted of 1 318 children and parents from 3 kindergartens, and the control group consisted of 1 546 children and parents from 4 kindergartens. Parents in the intervention group received combination of online and offline health education intervention measures for 2 months, while parents in the control group received no intervention measures. Logistic regression analysis was used to evaluate the effect of parents' perception of their children's weight in intervention group and control group. Results After controlling for imbalanced variables such as parents' education level, total monthly family income, and parents' perception of their children's weight, there was a statistically significant difference in the improvement of parents' perception of their children's weight status between two groups after intervention(OR=2.175,95%CI:1.536 - 3.080,P<0.05). After intervention, the improvement of parents' perception of boys' weight status in intervention group was better than that in control group(OR=2.985, 95%CI: 1.878 - 4.745, P<0.05). There was no statistically significant difference in the degree of improvement in perceived weight status among girls' parents after intervention(P＞0.05). Regardless of whether the child's weight status was normal or not, parents in the intervention group showed better improvement in their perception of their children's weight status than the control group(OR=1.558, 6.111, 95%CI:1.025 - 2.368, 2.811 - 13.287, P<0.05). Conclusion Health education measures can improve the perception bias of parents towards their preschool children's weight, and the intervention effect varies among children of different genders and weight states.

摘要： 目的 探讨健康教育干预措施对改善家长对子女体重感知能力的效果,为学龄前肥胖儿童干预提供科学依据。方法 2020年10月整群随机抽取罗湖区7所幼儿园在园儿童,并随机分为干预组和对照组,其中干预组3所幼儿园共1 318名儿童及家长,对照组4所幼儿园共1 546名儿童及家长。干预组幼儿园家长进行为期2个月的线上结合线下健康教育干预措施,对照组幼儿园家长采用空白对照(即不采取任何干预措施),采用多分类Logistic回归分析评价干预后干预组与对照组在对子女体重感知的效果。结果 控制不均衡变量(父母文化程度、家庭月总收入、家长对子女体重感知)后,干预后干预组和对照组家长对子女体重感知的改善程度差异有统计学意义(OR=2.175,95%CI:1.536～3.080,P＜0.05);干预后干预组男生家长对子女体重状态感知的改善程度优于对照组家长(OR=2.985,95%CI:1.878～4.745,P＜0.05);干预后女生家长对子女体重状态感知的改善程度差异无统计学意义(P＞0.05);无论儿童体重状态正常与否,干预后干预组家长对子女体重状态感知的改善程度均优于对照组家长(OR=1.558、6.111,95%CI:1.025～2.368,2.811～13.287,P＜0.05)。结论 健康教育措施可改善学龄前儿童家长对其子女体重感知偏差,且在不同性别、体重状态儿童的干预效果不同。
