Abstract

BACKGROUND

The obesity-psychological distress relationship remains controversial.

PURPOSE

This study aims to assess whether adolescents' psychological distress was associated with body mass index (BMI) class membership determined by latent class analysis.

METHODS

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.

RESULTS

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.

CONCLUSIONS

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.

摘要

背景

肥胖与心理困扰之间的关系仍存在争议。

目的

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)类别成员身份有关。

方法

在 4 年内,对 1528 名青少年进行了每年一次的困扰(焦虑、抑郁)和 BMI 测量。生长混合模型为具有 2-11 个类别的模型推导出潜在的 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困扰与类别成员身份的关系。

结果

BMI 轨迹基本平坦。五类别模型(正常体重(48.8%)、超重(36.7%)、肥胖变超重(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)。较高的困扰与较高的基线 BMI 相关,因此与类别成员身份相关。

结论

在青少年时期,心理困扰与较高的 BMI 类别有关。要确定困扰是否“导致”体重增加更多,可能需要对年轻人群进行研究。
