A longitudinal study (15years) investigates heroin use patterns following precocious transition experiences for gang-affiliated Mexican-American males (n=119) in San Antonio, Texas. Five precocious transitions are examined: cohabitation, early nest leaving, school dropout, teenage parenthood, and unemployment (while not in school). Half of these men used heroin over the follow-up period for an average of under 4years. Findings from a zero-inflated Poisson model indicate that while these transitions do not have a significant effect on initiation of heroin use, they do have an important influence on individual's drug trajectories once they have initiated. Early-nest leaving and teenage parenthood are protective factors for continued heroin use while dropping out of high school and cohabiting during this same period are risk factors. Findings are discussed within the context of these disadvantaged and marginalized communities.
一项为期15年的纵向研究，调查了得克萨斯州圣安东尼奥市119名与帮派有关联的墨西哥裔美国男性在经历早熟转变后的海洛因使用模式。研究考察了五种早熟转变情况：同居、过早离家、辍学、少女怀孕生子以及（未上学期间的）失业。在随访期内，这些男性中有一半人使用过海洛因，平均使用时间不到4年。零膨胀泊松模型的研究结果表明，虽然这些转变对海洛因使用的起始没有显著影响，但一旦开始使用，它们对个人的吸毒轨迹有重要影响。过早离家和少女怀孕生子是持续使用海洛因的保护因素，而同期辍学和同居则是危险因素。研究结果将在这些弱势和边缘化社区的背景下进行讨论。
