To determine the longitudinal associations between perceived pubertal timing and recent substance use between the ages of 11 and 17 years.
DESIGN, SETTING AND PARTICIPANTS: A school-based cohort sequential study of adolescents in rural North Carolina, USA (n = 6892, 50% female) in the 6-8th grades at baseline and interviewed across five consecutive semesters.
Self-administered questionnaires in a group setting measured perceived pubertal development using the Pubertal Development Scale and adolescents reported past 3-month use of cigarettes, alcohol and marijuana. Latent class growth analysis determined the longitudinal relationships between perceived pubertal timing (early, on-time and late) and use of the three substances.
A negative quadratic model was the best-fitting model for all three substances. Higher proportions of early developers had used cigarettes and marijuana within the past 3 months at age 11 compared with on-time (P < 0.001 and P = 0.013) and late developers (P = 0.010 and P = 0.014) and a higher proportion of early developers had recently used alcohol at age 11 compared with on-time adolescents (P < 0.001). However, the proportion of recent cigarette and marijuana users increased more across adolescence for on-time adolescents compared with early developers (P = 0.020 and P = 0.037). Desistance in the proportion of substance users was similar for all adolescents (all P > 0.050).
Adolescents who believe they are more advanced in puberty than their peers are more likely to have used cigarettes, alcohol and marijuana recently compared with adolescents who believe they are on-time or late developing; these findings are mainly due to differences in use at age 11.
确定 11 至 17 岁时感知的青春期开始时间与近期物质使用之间的纵向关联。
设计、设置和参与者：这是一项在美国北卡罗来纳州农村地区开展的基于学校的队列序贯研究，纳入了基线时处于 6-8 年级的青少年（n=6892，女性占 50%），并在连续五个学期进行了访谈。
在小组环境中，使用青春期发育量表自我管理问卷来测量感知的青春期发育，青少年报告过去 3 个月内使用香烟、酒精和大麻的情况。潜在类别增长分析确定了感知的青春期开始时间（早、准时和晚）与三种物质使用之间的纵向关系。
对于所有三种物质，负二次模型是最佳拟合模型。与准时（P<0.001 和 P=0.013）和晚发育者（P=0.010 和 P=0.014）相比，较早发育者在 11 岁时过去 3 个月内使用香烟和大麻的比例更高，并且与准时青少年相比，较早发育者在 11 岁时最近使用酒精的比例更高（P<0.001）。然而，与早期发育者相比，准时发育者在整个青春期内最近使用香烟和大麻的比例增加更多（P=0.020 和 P=0.037）。所有青少年的物质使用者比例下降相似（所有 P>0.050）。
与认为自己发育准时或晚的青少年相比，认为自己发育更超前的青少年最近更有可能使用香烟、酒精和大麻；这些发现主要归因于 11 岁时的使用差异。
