Abstract

Previous research on pubertal timing has either evaluated contextual predictors of early puberty or negative adjustment outcomes associated with off-time development, especially early maturation. In this study, we integrated these 2 lines of research by evaluating the moderating influence of early childhood household risk on associations between early puberty and 8th-grade substance use in a longitudinal sample of 1,070 participants. We determined trajectories of early childhood household risk using group-based trajectory analysis. Rates of early maturation were higher but not significantly so in groups with high household risk. Early timing was associated with higher rates of substance initiation only among individuals with a history of high household risk.

摘要

先前关于青春期启动的研究要么评估了青春期提前的环境预测因子,要么评估了与发育时间异常(尤其是性早熟)相关的负面适应结果。在这项研究中,我们通过在一个包含 1070 名参与者的纵向样本中评估儿童早期家庭风险对青春期提前与 8 年级物质使用之间关联的调节影响,将这两条研究线索整合在一起。我们使用基于群组的轨迹分析确定了儿童早期家庭风险的轨迹。具有高家庭风险的群组中,性早熟的发生率较高,但无统计学意义。仅在有高家庭风险史的个体中,早期启动与更高的物质使用起始率相关。
