Emerging studies have explored the possibility of ADHD and associated abnormal eating behaviors as catalysts for obesity in children and adolescents. However, results were largely inconsistent. This study aims to explore the effects of ADHD and abnormal eating behaviors (including eating disorders, emotional eating, and bedtime eating) on obesity, and to assess the moderating role of abnormal eating behaviors between ADHD symptoms and BMI in Chinese children and adolescents.
We recruited 546 grade 3 to 11 students and their parents by stratified random sampling from three primary schools and four middle schools in Shanghai, China. This study used parent-reported versions of the ADHD Rating Scale-IV to assess ADHD symptoms, the Eating Attitudes Test and the Children's Eating Attitude Test to assess eating disorder (ED) symptoms, and the Child Eating Behavior Questionnaire to collect information about other abnormal eating behaviors at baseline and at a follow-up survey 1 year later.
Hierarchical linear regression analysis revealed that ED played a moderating role in the relationship between ADHD symptoms and BMI in addition to age ( = .003, = .008). The simple slope test showed that ADHD symptoms positively correlated with BMI ofs in the older age group with a high level of ED symptoms ( = .16, < .001). Moreover, the baseline ED symptoms ( = .03, = .032) and ADHD symptoms ( = .12, = .015) increased the students' BMI one year later after controlling for confounding factors.
Findings of this study suggest that ADHD and ED symptoms raised the students' BMI separately. Moreover, ADHD and ED symptoms raised the students' BMI separately. Moreover, a combined high level of ADHD and ED symptoms is correlated with students' high BMI in the older age group.
新兴研究探讨了注意力缺陷多动障碍（ADHD）及相关异常饮食行为作为儿童和青少年肥胖催化剂的可能性。然而，结果在很大程度上并不一致。本研究旨在探讨ADHD和异常饮食行为（包括饮食失调、情绪化进食和夜间进食）对肥胖的影响，并评估异常饮食行为在中国儿童和青少年中ADHD症状与体重指数（BMI）之间的调节作用。
我们通过分层随机抽样从中国上海的三所小学和四所中学招募了546名三至十一年级的学生及其家长。本研究使用家长报告版的ADHD评定量表第四版来评估ADHD症状，使用饮食态度测试和儿童饮食态度测试来评估饮食失调（ED）症状，并使用儿童饮食行为问卷在基线时和一年后的随访调查中收集有关其他异常饮食行为的信息。
分层线性回归分析显示，除年龄外，ED在ADHD症状与BMI的关系中起调节作用（β = 0.003，p = 0.008）。简单斜率检验表明，在ED症状水平较高的老年组中，ADHD症状与BMI呈正相关（β = 0.16，p < 0.001）。此外，在控制混杂因素后，基线时的ED症状（β = 0.03，p = 0.032）和ADHD症状（β = 0.12，p = 0.015）在一年后增加了学生的BMI。
本研究结果表明，ADHD和ED症状分别增加了学生的BMI。此外，ADHD和ED症状共同作用，在老年组中，高水平的ADHD和ED症状与学生的高BMI相关。
