The aim of this study was to investigate whether there are different classes of body mass index (BMI) development from early adolescence to young adulthood and whether these classes are related to the number of adverse life events children experienced.
Data were from the TRAILS (TRacking Adolescents' Individual Lives Survey) cohort (n = 2,218). Height and weight were objectively measured five times between participants' ages 10 to 12 years and 21 to 23 years. Parents reported on the occurrence of adverse life events in their child's life in an interview when children were 10 to 12 years old. Unconditional and conditional growth mixture modeling was used for statistical analysis.
"Normal weight" (75.1%), "late onset overweight" (20.1%), and "early onset overweight" classes (4.8%) were identified. In analyses unadjusted for additional covariates, children who experienced a higher number of adverse events had higher odds to be in the late onset overweight (OR [95% CI] = 1.08 [1.00-1.17]) than the normal weight class, but the association was attenuated in analyses adjusted for additional covariates (OR [95% CI] = 1.07 [0.98-1.16]).
Three BMI trajectory classes can be distinguished from early adolescence to young adulthood. The accumulation of adverse life events is not related to BMI trajectory class.
本研究旨在探讨从青少年早期到成年早期是否存在不同类别的体重指数（BMI）发展，以及这些类别是否与儿童经历的不良生活事件数量有关。
数据来自 TRAILS（青少年个体生活追踪调查）队列（n=2218）。在参与者 10 至 12 岁和 21 至 23 岁之间，身高和体重被客观测量了五次。当孩子 10 至 12 岁时，父母在访谈中报告了孩子生活中的不良生活事件的发生情况。使用无条件和条件增长混合建模进行统计分析。
确定了“正常体重”（75.1%）、“晚期超重”（20.1%）和“早期超重”（4.8%）类别。在未调整其他协变量的分析中，经历更多不良事件的儿童比正常体重组更有可能处于晚期超重（OR [95%CI]=1.08 [1.00-1.17]），但在调整了其他协变量的分析中，这种关联减弱（OR [95%CI]=1.07 [0.98-1.16]）。
可以从青少年早期到成年早期区分出三种 BMI 轨迹类别。不良生活事件的积累与 BMI 轨迹类别无关。
