The goal of the study was to examine whether baseline body mass index (BMI) z-scores and weight status predicted conduct disorder (CD) symptoms in 368 adolescents (15-17 years).
Participants in the 10th and 11th grades completed self-report questionnaires at baseline and at a 2-year follow-up. Baseline BMI z-scores and weight status were derived from self-reports of height and weight. CD symptoms were assessed using a symptom checklist. Covariates included baseline demographics, depressive symptoms, alcohol consumption, drug use, and a retrospective report of CD symptoms before age 15 years.
A cubic association was observed between baseline BMI z-scores and follow-up CD symptoms (p = .047), such that a positive association emerged only among adolescents with BMI z-scores of greater than ∼1.5. Adolescents who were obese at baseline reported more follow-up CD symptoms than nonoverweight adolescents (p = .008). Higher baseline BMI z-scores were associated with increased odds of endorsing probable CD at follow-up (p's < .03). Obese adolescents were more likely to report the presence of probable CD at follow-up than overweight and nonoverweight adolescents (p's ≤ .01).
Findings suggest that nutritional status, particularly high BMI z-scores and obese weight status, may contribute to elevated CD symptoms during adolescence, which should be dually addressed in screening and intervention efforts.
本研究旨在探讨基线体重指数（BMI）z 分数和体重状况是否能预测 368 名青少年（15-17 岁）的品行障碍（CD）症状。
10 年级和 11 年级的参与者在基线和 2 年随访时完成了自我报告问卷。基线 BMI z 分数和体重状况由身高和体重的自我报告得出。使用症状清单评估 CD 症状。协变量包括基线人口统计学、抑郁症状、饮酒、药物使用以及 15 岁前 CD 症状的回顾性报告。
观察到基线 BMI z 分数与随访 CD 症状之间存在三次方关联（p =.047），只有 BMI z 分数大于约 1.5 的青少年才表现出正相关。与非超重青少年相比，基线肥胖的青少年报告了更多的随访 CD 症状（p =.008）。较高的基线 BMI z 分数与随访时可能存在 CD 的几率增加相关（p's <.03）。与超重和非超重青少年相比，肥胖青少年在随访时更有可能报告存在可能的 CD（p's ≤.01）。
研究结果表明，营养状况，特别是高 BMI z 分数和肥胖体重状况，可能导致青少年时期 CD 症状的升高，在筛查和干预工作中应同时解决这两个问题。
