目的 探讨注意力缺陷多动障碍(attention deficit hyperactivity disorder, ADHD)儿童的骨龄发育水平与体质指数(body mass index, BMI), 为ADHD开展有效的治疗与预防措施提供依据。方法 采取自愿原则选自本院保健科心理门诊6~11岁的符合美国精神障碍诊断统计手册(DSM-Ⅳ)诊断标准的初诊ADHD儿童53例为观察组, 生长发育门诊中选取正常健康儿童53例为对照组, 采用数字化摄影仪拍摄左手腕骨正位X线片, 用统一标准测量身高、体重, 按CHN法(中国人手腕部骨发育评价标准)骨龄标准评价手腕骨龄片。结果 观察组身高年龄与实际年龄的差均值(0.8±1.1)与对照组(-0.1±0.6)的比较差异有统计学意义(P<0.001), 骨龄与实际年龄差均值与对照组比较差异有高度统计学意义(P<0.001), 遗传身高与预测终身高的差均值(1.1±1.0)与对照组(1.0±0.4)比较差异无统计学意义(P>0.05), BMI观察组(18.1±3.5)与对照组(16.2±2.3)两组均值比较差异有统计学意义(P<0.05)。结论 ADHD儿童的骨龄发育水平较早, 体质指数偏高, 不影响成年身高。

Objective To study attention deficit hyperactivity disorder (ADHD) children's bone age developmental level and body mass index and provide the basis of effective ADHD treatment and preventive measures. Methods From mental health department, 53 cases of 6~11 year-old patient newly diagnosed ADHD were selected as the observation group, in compliance with U.S.Diagnostic Statistical Manual of Mental Disorders (DSM-Ⅳ) diagnostic criteria.53 cases of healthy children with same bone age and actual age were chosen as the control group.Digital photography meter was used to shoot wrist bone X-ray, with a unified standard height and weight measurements, bone age standard evaluation method by CHN was used to judge wrist bone age film. Results Mean of difference between height age and actual age was significantly different (P<0.001) between observation group(0.8±1.1) and control group(-0.1±0.6);Mean of difference between bone age and actual age was significantly different (P<0.001) between observation group(1.1±1.0) and control group(1.0±0.4);Mean of difference between forecast lifetime height and genetic height was not different (P>0.05) between observation group(1.5±5.8)and control group(-0.1±22.1).Mean of body mass index (BMI) in two groups(observatina group 18.1±3.5, control group 16.2±2.3) had differences (P<0.05). Conclusion For children with ADHD, bone age developmental level is earlier and BMI is higher than healthy children.Yet, it does not affect final height during adulthood.
