We examined the joint associations of marital status and duration of cohabitation on self-reported intimate partner violence, substance use, and postpartum depression among childbearing women.
We analyzed data from the 2006-2007 Canadian Maternity Experiences Survey, a cross-sectional nationwide sample of 6421 childbearing women. Cohabiting women were married or nonmarried women living with a partner; noncohabiters were single, divorced, or separated women. We further categorized cohabiters by their duration of cohabitation (≤ 2, 3-5, or > 5 years). We used logistic regression to generate adjusted odds ratios and 95% confidence intervals.
About 92% of women were cohabiters. Compared with married women living with a husband more than 5 years, unmarried women cohabiting for 2 years or less were at higher odds of intimate partner violence (adjusted odds ratio [AOR] = 4.64; 95% confidence interval [CI] = 2.85, 7.56), substance use (AOR = 5.36; 95% CI = 3.06, 9.39), and postpartum depression (AOR = 1.87; 95% CI = 1.25, 2.80); these risk estimates declined with duration of cohabitation.
Research on maternal and child health would benefit from distinguishing between married and unmarried cohabiting women, and their duration of cohabitation.
本研究旨在探讨婚姻状况和同居时间对有孩女性自报告的亲密伴侣暴力、物质使用和产后抑郁的联合影响。
我们分析了 2006-2007 年加拿大母婴经历调查的数据，该调查是一项全国性的横断面研究，共纳入了 6421 名有孩女性。同居女性包括已婚或未婚但与伴侣同居的女性；非同居者包括单身、离婚或分居的女性。我们进一步根据同居时间（≤2 年、3-5 年或>5 年）将同居者进行分类。我们使用逻辑回归分析生成调整后的优势比（OR）和 95%置信区间（CI）。
约 92%的女性为同居者。与与丈夫同居超过 5 年的已婚女性相比，同居时间为 2 年或更短的未婚女性发生亲密伴侣暴力（调整后的 OR [AOR] = 4.64；95%置信区间 [CI] = 2.85，7.56）、物质使用（AOR = 5.36；95% CI = 3.06，9.39）和产后抑郁（AOR = 1.87；95% CI = 1.25，2.80）的风险更高；这些风险估计随着同居时间的延长而降低。
在母婴健康研究中，将已婚和未婚同居女性及其同居时间区分开来将有助于研究的开展。
