Intimate partner violence and reproductive coercion are associated with unintended pregnancies and STDs. Greater condom negotiation self-efficacy among young women may mediate these associations.
A sample of 841 female adolescents (aged 16-19) and 1,387 young adult women (aged 20-24) recruited from 24 family planning clinics in western Pennsylvania in 2011-2012 reported on intimate partner violence, reproductive coercion, condom negotiation self-efficacy and sexual health outcomes at baseline and four- and 12-month follow-ups. Mixed models were used to test associations of intimate partner violence and reproductive coercion with unintended pregnancy and STD diagnosis. The Sobel test of mediation was used to measure indirect effects of condom negotiation self-efficacy.
At baseline, 15% of adolescents and 11% of young adults reported recent intimate partner violence victimization; 7% and 6%, respectively, reported recent reproductive coercion. For both age-groups, intimate partner violence and reproductive coercion were associated with a reduced level of condom negotiation self-efficacy (coefficients, -0.27 to -0.13) and increased odds of STD diagnosis (odds ratios, 1.03-1.1). However, only reproductive coercion was associated with unintended pregnancy (odds ratios, 1.1 for each group). The only association that condom negotiation self-efficacy mediated was between reproductive coercion and unintended pregnancy among young adults (17% of total effect).
Targeting condom negotiation self-efficacy alone in abusive relationships would likely not translate into improved sexual health outcomes in this population. Other strategies are needed to prevent unintended pregnancy and STDs.
亲密伴侣暴力和生殖胁迫与意外怀孕及性传播疾病相关。年轻女性更高的避孕套协商自我效能感可能会调节这些关联。
2011年至2012年从宾夕法尼亚西部的24家计划生育诊所招募了841名女性青少年(16 - 19岁)和1387名年轻成年女性(20 - 24岁),她们在基线、4个月和12个月随访时报告了亲密伴侣暴力、生殖胁迫、避孕套协商自我效能感和性健康结果。使用混合模型来测试亲密伴侣暴力和生殖胁迫与意外怀孕及性传播疾病诊断之间的关联。中介效应的索贝尔检验用于测量避孕套协商自我效能感的间接效应。
在基线时,15%的青少年和11%的年轻成年人报告近期遭受亲密伴侣暴力;分别有7%和6%报告近期遭受生殖胁迫。对于这两个年龄组,亲密伴侣暴力和生殖胁迫都与较低水平的避孕套协商自我效能感(系数为 -0.27至 -0.13)以及性传播疾病诊断几率增加(比值比为1.03 - 1.1)相关。然而,只有生殖胁迫与意外怀孕相关(每组比值比为1.1)。避孕套协商自我效能感仅介导了年轻成年人中生殖胁迫与意外怀孕之间的关联(占总效应的17%)。
在虐待关系中仅针对避孕套协商自我效能感可能无法转化为该人群性健康结果的改善。需要其他策略来预防意外怀孕和性传播疾病。
