Intimate partner violence is more common in polygynous couples than monogamous couples, but the extent that this association is modified by the husband's alcohol consumption is unknown. The objectives of this study are: (1) To describe the extent to which polygyny is associated with self-reported experience of intimate partner violence among women receiving postpartum care; (2) To describe the extent to which the mentioned association is modified by the husband's alcohol consumption.
We conducted a hospital-based cross-sectional study among women age 18 years or older receiving postpartum care at 8 public hospitals in 3 provinces in Northern and Northeastern Thailand using self-administered questionnaires. We analyzed data using descriptive statistics, logistic regression, and stratified analyses.
A total of 1207 women agreed to participate in the study, 8% of whom reported that their husbands practiced polygyny. Women in a polygynous relationship were more likely than women in monogamous relationships to experience intimate partner violence (11.7% vs. 3.6%, Adjusted OR = 2.23; 95% CI = 0.94, 5.26). The prevalence of intimate partner violence was relatively low in both groups among women whose husbands did not drink (2.9% vs. 0%, Adjusted OR = N/A), and very high in both groups among those whose husbands binge-drank (46.2% vs. 20.8%, Adjusted OR = 9.54; 95% CI = 1.10, 82.54). However, the Breslow-Day Test of Homogeneity suggested that there was no statistically significant effect modification (p-value = 0.259).
Stakeholders in intimate partner violence should consider both alcohol use (particularly binge-drinking) and polygyny as risk factors for intimate partner violence. However, caveats regarding study design, misclassification and potential information bias, and lack of generalizability should be considered in the interpretation of the study findings.
与一夫一妻制夫妇相比，多配偶制夫妇中更常见亲密伴侣暴力，但丈夫饮酒对这种关联的影响程度尚不清楚。本研究的目的是：（1）描述在接受产后护理的妇女中，多配偶制与自我报告的亲密伴侣暴力经历之间的关联程度；（2）描述丈夫饮酒对这种关联的影响程度。
我们在泰国北部和东北部 3 个省的 8 家公立医院对年龄在 18 岁及以上接受产后护理的妇女进行了一项基于医院的横断面研究，使用自我管理问卷。我们使用描述性统计、逻辑回归和分层分析来分析数据。
共有 1207 名妇女同意参加研究，其中 8%的妇女报告其丈夫实行多配偶制。与一夫一妻制关系的妇女相比，多配偶制关系的妇女更有可能经历亲密伴侣暴力（11.7%对 3.6%，调整后的比值比 = 2.23；95%置信区间 = 0.94，5.26）。在丈夫不饮酒的妇女中，两组的亲密伴侣暴力发生率都相对较低（2.9%对 0%，调整后的比值比 = 不适用），而在丈夫狂饮的妇女中，两组的亲密伴侣暴力发生率都非常高（46.2%对 20.8%，调整后的比值比 = 9.54；95%置信区间 = 1.10，82.54）。然而，Breslow-Day 同质性检验表明，没有统计学意义的效应修饰（p 值 = 0.259）。
亲密伴侣暴力的利益相关者应将酒精使用（特别是狂饮）和多配偶制视为亲密伴侣暴力的风险因素。然而，在解释研究结果时，应考虑研究设计、分类和潜在信息偏倚以及缺乏普遍性的局限性。
