摘要: 目的 探讨学龄儿童注意缺陷多动障碍(attention-deficit/hyperactivity disorder,ADHD)症状与多维肥胖表型(基于体质量指数及体成分指标)的关联,并分析不良饮食行为在其中的潜在中介作用。方法 采用横断面设计,通过分层整群抽样法纳入珠海市2023年6至18岁学龄儿童6624名。测量其身高、体重,计算体质量指数(BMI),采用生物电阻抗分析法测量体脂率、躯干体脂率和腰臀比。通过父母版斯诺佩评估量表(Swanson Nolan and Pelham-Ⅳ,SNAP-Ⅳ)评估ADHD症状,通过儿童自评版荷兰饮食行为问卷评估不良饮食行为。四种肥胖表型包括:BMI定义的肥胖;肥胖伴高腰臀比;肥胖伴高体脂率;肥胖伴高躯干体脂率。采用多水平逻辑回归进行关联分析,Bootstrap法检验中介效应。结果 ADHD症状筛查阳性率为6.9%,肥胖检出率为10.3%。受试总体的多动冲动症状得分与肥胖(OR=1.31)和肥胖伴高腰臀比(OR=1.31)呈正相关。女生的多动冲动症状得分还与肥胖伴高体脂率(OR=1.40)和肥胖伴高躯干体脂率(OR=1.38)显著相关;男生中未见上述指标显著关联。限制性饮食得分在上述关联中有潜在中介效应,中介效应占比在总体中为61.0%~72.2%,在女生中为35.9%~39.1%。结论 学龄儿童ADHD症状,尤其是多动冲动症状,不仅与BMI定义的肥胖相关,更与以中心性肥胖为特征的多维肥胖表型相关,且在女生中更为突出;限制性饮食可能在两者关联中发挥重要的潜在中介作用。肥胖防控中可关注伴多动冲动症状的儿童及其饮食行为特征,体成分指标有助于更精细的表型描述,其在常规监测中的应用价值仍需前瞻性研究验证。

Abstract: Objective To explore the association between attention-deficit/hyperactivity disorder (ADHD) symptoms and multidimensional obesity phenotypes defined by BMI and body composition indicators in school-aged children, and further analyze the potential mediating role of unhealthy eating behaviors. Methods A cross-sectional study was conducted among 6624 children aged 6–18 years from Zhuhai, China, recruited via stratified cluster sampling in 2023. Height and weight were measured to calculate BMI, and body composition indicators, including body fat percentage and waist-to-hip ratio, were assessed by bioelectrical impedance analysis. ADHD symptoms were evaluated with the parent-rated Swanson Nolan and Pelham-Ⅳ (SNAP-Ⅳ), while eating behaviors were assessed with the children's self-reported Dutch Eating Behavior Questionnaire. Four obesity phenotypes were defined:obesity by BMI;obesity with a high waist-to-hip ratio;obesity with high body fat percentage; and obesity with high trunk fat percentage. Multilevel logistic regression was performed for association analysis, and mediation effects were tested using the bootstrap method. Results The positive screening rate for ADHD symptoms was 6.9%, and the detection rate of obesity was 10.3%. Among all participants,hyperactive-impulsive symptom scores were positively associated with obesity (OR=1.31) and obesity with a high waist-to-hip ratio (OR=1.31). Among girls, these scores were also significantly positively associated with obesity with high body fat percentage (OR=1.40) and obesity with high trunk fat percentage (OR=1.38),whereas no significant associations of these indicators were found in boys. Restrained eating scores showed a potential mediating effect in these associations, explaining 61.0%-72.2% of the total effect in the overall sample and 35.9%-39.1% in girls. Conclusion ADHD symptoms in school-aged children are associated not only with the risk of obesity but also with multidimensional obesity phenotypes characterized by central fat accumulation. Restrained eating may be an important potential mediator in this association. For obesity prevention and control, attention should be paid to children with hyperactive-impulsive symptoms and their eating behaviors. Body composition indicators may facilitate refined phenotyping, yet their value in routine monitoring requires validation in prospective studies.
