目的 探讨超重肥胖儿童与正常体重儿童智力及执行功能的差异,为肥胖儿童的早期干预提供科学依据。方法 纳入中山大学儿童青少年体质研究中心自2021年10月—2022年4月招募的6~9岁儿童341人,其中超重肥胖儿童56人,正常体重儿童285人。测量儿童身高、体重,分别采用中文版韦氏儿童智力量表第4版(WISC-Ⅳ)和学龄儿童执行功能行为评定量表(BRIEF)评估儿童智力水平、执行功能各成分水平。结果 超重肥胖组与正常体重组智力测试的各分测验及总智商分数差异无统计学意义(P＞0.05)。超重肥胖组行为管理指数、元认知指数及各因子得分均高于正常体重组(P＜0.001),两指数及各因子异常率均高于正常体重组(P＜0.001),且在男生组更普遍(P＜0.001)。Logistic回归分析表明,超重肥胖与执行功能总分异常(OR=10.46, 95%CI:4.80~22.82)、行为管理指数异常(OR=15.98, 95%CI:5.56~45.93)、元认知指数异常(OR=4.74, 95%CI:2.49~9.04)的发生风险增加有关(P<0.001)。结论 超重肥胖儿童和正常体重儿童智力水平无显著差异,但日常生活中的执行功能广泛受损。
Abstract
Objective To explore the differences in intelligence and executive function between overweight/obese children and normal weight children, in order to provide scientific reference for early intervention of overweight and obesity. Methods A total of 341 children aged 6 to 9 were enrolled from the Center for Child and Adolescent Psychology and Behavioral Development of Sun Yat-sen University from October 2021 to April 2022, including 56 overweight/obese children and 285 normal weight children. The height and weight of children were measured. The China-Wechsler Intelligence Scale for Children-Fourth Edition (WISC-Ⅳ) and the Behavioral Rating Inventory of Executive Function (BRIEF) were used to assess the intelligence and executive function of children. Results There were no significant differences in intelligence quotient (IQ) scores between the two groups(P＞0.05). The overweight and obese group had higher scores of behavioral regulation index(BRI), metacogniton index(MI) and other factors than the normal weight group, which was more common in the male group (P＜0.001). Logistic regression analysis showed that overweight and obesity were related to the increased risk of abnormal total score of executive function (OR=10.46, 95%CI:4.80 - 22.82,P<0.001), BRI (OR=15.98, 95%CI:5.56 - 45.93,P<0.001) and MI (OR=4.74, 95%CI:2.49 - 9.04,P<0.001). Conclusion There is no significant difference in intelligence between overweight/obese children and normal weight children, but their executive function of daily life is widely impaired.
