肥胖与心理困扰的关系仍然存在争议。本研究旨在评估青少年的心理困扰是否与通过潜在类别分析确定的体重指数（BMI）类别成员资格相关。四年来，每年对 1,528 名青少年进行痛苦（焦虑、抑郁）和体重指数测量。生长混合模型为具有 2-11 个类别的模型导出了潜在 BMI 轨迹类别。使用向量广义线性回归在最佳拟合模型中检查痛苦与类别成员的关系。 BMI 轨迹基本持平。五级模型[正常体重（48.8%）、超重（36.7%）、超重肥胖（3.7%）、肥胖（9.4%）和严重肥胖（1.3%）]是首选模型（贝叶斯信息准则=22789.2，df=31；ρ=0.84）。更大的痛苦与较高的基线体重指数相关，因此也与较高的班级成员资格相关。心理困扰与青春期较高的 BMI 等级相关。要确定痛苦是否“导致”体重增加可能需要对年轻人进行研究。
The obesity–psychological distress relationship remains controversial. This study aims to assess whether adolescents’ psychological distress was associated with body mass index (BMI) class membership determined by latent class analysis. Distress (anxiety, depression) and BMI were measured annually for 4 years in 1,528 adolescents. Growth mixture modeling derived latent BMI trajectory classes for models with 2–11 classes. The relationship of distress to class membership was examined in the best-fitting model using vector generalized linear regression. BMI trajectories were basically flat. The five-class model [normal weight (48.8%), overweight (36.7%), obese who become overweight (3.7%), obese (9.4%), and severely obese (1.3%)] was the preferred model (Bayesian information criterion=22789.2, df=31; ρ=0.84). Greater distress was associated with higher baseline BMI and, therefore, class membership. Psychological distress is associated with higher BMI class during adolescence. To determine whether distress “leads” to greater weight gain may require studies of younger populations.
