本研究的目的是使用国家青少年健康纵向研究的女性样本来详细检查青春期时间与药物使用开始之间的关系。该样本包括 966 名女性，她们是第一波 7 年级学生和第二波 8 年级学生。样本参与者中大约有 69% 是白人，20% 是非裔美国人，4% 是亚洲或太平洋岛民，2% 是美洲印第安人，4% 是其他西班牙裔，1% 是其他非西班牙裔。根据七年级时测量的身体变化（乳房大小和身体曲线增加）的自我报告，百分之二十的女性被确定为早熟者。假设这些参与者出现药物滥用的风险增加。早熟者与准时和晚熟者在物质使用开始方面存在重要差异。在七年级期间，早熟组的女性处于物质使用最高级阶段（包括饮酒、醉酒、吸烟和吸食大麻）的可能性是准时/晚熟组的女性的三倍。患病率表明，早熟的人更有可能尝试饮酒、吸烟、喝醉和吸食大麻。前瞻性研究结果显示，早期开发人员更有可能在 7 年级和 8 年级之间摆脱“无物质使用”阶段（早期开发人员为 47%，而准时和晚期开发人员为 22%）。此外，早期开发者总体上更有可能在物质使用方面取得进步，无论他们在 7 级的使用水平如何。
The goal of this study is to examine in detail the relationship between pubertal timing and substance use onset using a sample of females from The National Longitudinal Study of Adolescent Health. The sample includes 966 females who were in 7th grade at Wave 1 and 8th grade at Wave 2. Participants in the sample are approximately 69% White, 20% African American, 4% Asian or Pacific Islander, 2% American Indian, 4% other, of Hispanic origin, and 1% other, not of Hispanic origin. Twenty percent of the females were identified as early maturers based on self-reports of body changes (increased breast size and body curviness) measured in 7th grade. These participants are hypothesized to be at increased risk for substance use onset. Important differences in substance use onset were found between early maturers and their on-time and late-maturing counterparts. During 7th grade, females in the early-maturing group are three times more likely to be in the most advanced stage of substance use (involving alcohol use, drunkenness, cigarette use, and marijuana use) than are those in the on-time/late group. Prevalence rates indicate that early maturers are more likely to have tried alcohol, tried cigarettes, been drunk, and tried marijuana. Prospective findings show that early developers are significantly more likely to transition out of the "No Substance Use" stage between 7th and 8th grade (47% for early developers vs. 22% for on-time and late developers). In addition, early developers are more likely to advance in substance use in general, regardless of their level of use at Grade 7.
