Background

Substance use is linked to increases in young women’s risk for intimate partner violence (IPV). Increased understanding of the magnitude of and changes in the associations between substance use and risk for IPV in the transition to emerging adulthood, and differences between Black and White women, could inform efforts to protect women from substance use-related harm.

Methods

Young women (N = 1,852; 59% Black, 41% White) in the Pittsburgh Girls Study completed yearly assessments at ages 17–21 on frequency of alcohol and cannabis use, and experiences of IPV (minor physical assault). Time-varying effect models (TVEMs) were used to examine changes in the strength of the association between frequency of alcohol and cannabis use with IPV across ages 17–21, controlling for time-invariant covariates (socioeconomic status, conduct problems, and depression).

Results

Across ages 17 to 21, White, relative to Black, women reported more frequent alcohol use and less frequent cannabis use, and lower rates of IPV. Alcohol use was not significantly associated with IPV at ages 17–21 among White women, but among Black women, alcohol use was associated with increased likelihood of IPV at ages 17–20. Cannabis use was associated with increased likelihood of IPV at ages 19–21 among Black women, and at ages 20–21 among White women.

Conclusions

Associations between IPV (specifically minor assault) in the context of a romantic relationship differed for alcohol and cannabis across ages 17–21, and by race, among White and Black women. Results highlight the importance of substance-specific prevention efforts that are timed and tailored to subgroups.

黑人和白人年轻女性的酒精和大麻使用与亲密伴侣暴力的时变关联

背景

药物使用与年轻女性遭受亲密伴侣暴力 (IPV) 的风险增加有关。对物质使用与 IPV 风险在向成年期过渡以及黑人和白人女性之间的差异之间关联的程度和变化的更多了解，可以为保护女性免受与物质使用相关的伤害的努力提供信息。

方法

匹兹堡女孩研究中的年轻女性（N = 1,852；59% 黑人，41% 白人）在 17-21 岁时完成了关于酒精和大麻使用频率以及 IPV（轻微身体攻击）经历的年度评估。时变效应模型 (TVEM) 用于检查 17-21 岁之间酒精和大麻使用频率与 IPV 之间关联强度的变化，控制时间不变的协变量（社会经济状况、行为问题和抑郁） .

结果

在 17 至 21 岁之间，相对于黑人，白人女性报告的饮酒频率更高，大麻使用频率更低，IPV 率更低。在白人女性中，酒精使用与 17-21 岁的 IPV 没有显着相关性，但在黑人女性中，饮酒与 17-20 岁的 IPV 可能性增加有关。大麻的使用与 19-21 岁黑人女性和 20-21 岁白人女性发生 IPV 的可能性增加有关。

结论

在浪漫关系的背景下，IPV（特别是轻微攻击）之间的关联对于 17-21 岁的酒精和大麻以及白人和黑人女性的种族不同。结果强调了针对亚组进行定时和定制的特定物质预防工作的重要性。
