摘要

背景：青春期是物质使用开始的关键时期，其后果是成人期的成瘾和社会心理问题。然而，年龄和种族/民族等关键变量在开始治疗方面的差异仍未得到充分研究。目的：本研究考察了8个种族/民族群体（亚洲或太平洋岛民、黑人、土著、西班牙裔白人、白人、白人-亚洲混血儿、白人-黑人混血儿和白人-土著混血儿）中年龄和同伴对酒精、大麻和吸烟的影响，并将混血儿群体与单一种族群体进行比较。方法：使用Add Health （n = 15,844，平均年龄= 15.6）和Monitoring the Future （MTF, n = 9,600，平均年龄18.4）的综合数据分析，我们应用离散时间生存分析来估计青春期（12-18岁）的起始危害，考虑到种族/民族、性别和同伴物质使用。结果：初次接触酒精和大麻的危害遵循年龄的二次函数，在16岁和18岁左右达到峰值。相比之下，卷烟开始使用的危害函数相对平缓。根据所考虑的具体亚群体和物质，混血儿青年相对于单种族同龄人通常表现出中等或更高的物质使用开始风险。在所有群体中，同伴物质使用与开始吸毒的增加有关，在开始吸毒的高峰年龄和不同种族群体的程度差异中，这种影响更强。结论：我们的研究结果表明，在混血儿和单混血儿青少年之间以及特定的混血儿亚群体之间，物质使用的开始风险和对同伴影响的易感性存在差异，这突出了在解决青少年物质使用问题时考虑亚群体差异的必要性。

Differences in substance use initiation patterns among biracial and monoracial adolescents: an integrative data analysis of two nationally representative samples

Background

Adolescence is a critical period for substance use initiation, with consequences for addiction and psychosocial problems in adulthood. However, differences in initiation by key variables such as age and racialized/ethnic group remain understudied.

Objectives

This study examined age and peer influence in relation to alcohol, cannabis, and cigarette initiation across eight racialized/ethnic groups (Asian or Pacific Islanders, Black, Indigenous, Hispanic White, White, Biracial White-Asian, Biracial White-Black, and Biracial White-Indigenous) to compare biracial groups with their monoracial counterparts.

Methods

Using integrated data analysis with Add Health (n = 15,844; mean age = 15.6) and Monitoring the Future (MTF; n = 9,600; mean age 18.4), we applied discrete-time survival analysis to estimate initiation hazards during adolescence (ages 12–18), accounting for racialized/ethnic group, sex, and peer substance use.

Results

The hazards for new initiations of alcohol and cannabis followed a quadratic function of age, peaking around ages 16 and 18. Cigarette use initiation, in contrast, had a relatively flat hazard function. Biracial youth typically showed intermediate or higher risk of substance use initiation relative to their monoracial peers depending on the specific subgroups and substances considered. Peer substance use was associated with increased initiation across all groups, with stronger effects during peak initiation ages and variations in magnitude across racialized groups.

Conclusion

Our findings show substance use initiation risks and susceptibility to peer influence differ between biracial and monoracial adolescents and between specific biracial subgroups, highlighting the need to consider subgroup differences when addressing adolescent substance use.

期刊介绍： Addictive Behaviors is an international peer-reviewed journal publishing high quality human research on addictive behaviors and disorders since 1975. The journal accepts submissions of full-length papers and short communications on substance-related addictions such as the abuse of alcohol, drugs and nicotine, and behavioral addictions involving gambling and technology. We primarily publish behavioral and psychosocial research but our articles span the fields of psychology, sociology, psychiatry, epidemiology, social policy, medicine, pharmacology and neuroscience. While theoretical orientations are diverse, the emphasis of the journal is primarily empirical. That is, sound experimental design combined with valid, reliable assessment and evaluation procedures are a requisite for acceptance. However, innovative and empirically oriented case studies that might encourage new lines of inquiry are accepted as well. Studies that clearly contribute to current knowledge of etiology, prevention, social policy or treatment are given priority. Scholarly commentaries on topical issues, systematic reviews, and mini reviews are encouraged. We especially welcome multimedia papers that incorporate video or audio components to better display methodology or findings. Studies can also be submitted to Addictive Behaviors? companion title, the open access journal Addictive Behaviors Reports, which has a particular interest in ''non-traditional'', innovative and empirically-oriented research such as negative/null data papers, replication studies, case reports on novel treatments, and cross-cultural research.
