评估妇女遭受亲密伴侣暴力和饮酒经历的前瞻性研究显示出好坏参半的结果，这些研究均来自高收入国家。使用来自南非年轻女性的纵向数据，我们评估身体IPV的变化是否影响酒精使用，以及酒精使用的变化是否影响身体IPV体验。2015年9月至2019年10月期间，对南非德科维尼市非正式定居点18-30岁妇女进行了后期分析，这些妇女参与了铺路石和创造未来的试验，在基线（n = 677）和24个月的终点（n = 545，保留率为80.5%）收集了数据。在这两个时间点，女性都被问及她们过去一年的身体IPV经历和酒精使用情况。我们估计了身体IPV随时间的变化，以及这是否与终末有害酒精使用有关。然后，我们估计了酒精使用随时间的变化，以及这是否与过去一年的物理IPV相关。在研究期间身体IPV增加的妇女更有可能在24个月时报告有害饮酒（比值为2.45,95%可信区间为1.21-4.97）。同样，随着时间的推移，报告饮酒增加的女性更有可能在24个月时报告去年的身体IPV（比值为2.04,95% CI为1.21-3.46）。在生活在城市贫困中的年轻妇女中，遭受亲密伴侣越来越多的身体暴力的妇女更有可能报告酒精使用的增加和问题。同样，报告在24个月内饮酒增加的妇女更有可能报告身体上的IPV。然而，没有证据表明酒精使用减少导致IPV减少，或者IPV经历减少导致酒精使用减少。未来的研究和干预措施需要考虑身体IPV和酒精使用的相互风险，重点关注共同的潜在驱动因素。
Prospective studies assessing women's experience of intimate partner violence (IPV) and alcohol use have shown mixed results and all are from high-income countries. Using longitudinal data from young women in South Africa we assess whether changes in physical IPV impact alcohol use, and whether changes in alcohol use impact physical IPV experience. Post-hoc analysis of women aged 18-30 living in informal settlements in eThekwini Municipality, South Africa, involved in the Stepping Stones and Creating Futures trial, between September 2015 and October 2019, with data collected at baseline (n = 677) and endline at 24 months (n = 545, 80.5% retention). At both timepoints, women were asked about their past year physical IPV experience and alcohol use. We estimated changes in physical IPV over time and whether this was associated with harmful alcohol use at endline. We then estimated changes in alcohol use over time, and whether this was associated with experience of past year physical IPV at endline. Women who experienced an increase in physical IPV over the study period were more likely to report harmful drinking at 24 months (aOR2.45, 95% CI 1.21-4.97). Similarly, women reporting increased alcohol use over time were more likely to report past year physical IPV at 24 months (aOR2.04, 95% CI 1.21-3.46). Among young women living in urban poverty those who experienced increasing physical violence from intimate partners were more likely to report increased and problematic alcohol use. Similarly, women reporting increasing alcohol use over 24 months were more likely to report physical IPV. However, there was no evidence that decreased alcohol use led to reductions in IPV, or that reduced IPV experience led to decreased alcohol use. Future research and interventions need to consider the reciprocal risks of physical IPV and alcohol use, with a focus on joint underlying drivers.
