Cross-sectional study.
Seven prefectures along the Yangtze River in the Anhui Province, China.
We included 412 participants aged 18 years or older (206 married HIV-discordant couples).
In this study, sexual behaviours included marital or extramarital sex in the past 6 months, as well as the frequency of marital sex and condom use (always, sometimes or never) if having marital sex in the past 6 months. We used stepwise ordinal logistic regression modelling to determine the correlates of condom use.
In total, 63.1% (130 of 206) of couples had marital sex in the past 6 months, of which 89.2% (116 of 130) used condoms consistently. Couples with more marital duration (OR=1.15; 95% CI: 1.03, 1.28) were more inclined to adhere to condom use, whereas those lacking support and care (OR=0.25; 95% CI: 0.07, 0.94) and being remarried (OR=0.08; 95% CI: 0.02, 0.43) were associated with less condom use. In addition, HIV-positive respondents were more likely to have extramarital sex than HIV-negative respondents (p=0.015).
The extramarital sex of HIV-positive spouses should be considered. Implementation of interventions, such as increasing support and care between spouses to promote marital intimacy and stability, could reduce unprotected sexual behaviour.
方法:横断面研究。
方法:安徽省长江沿岸的七个县,中国。
方法:我们纳入了412名18岁或以上的参与者(206名已婚HIV不和谐夫妇)。
方法:在本研究中,性行为包括过去6个月的婚姻或婚外性行为,以及婚姻性行为和避孕套使用的频率(总是,有时或从不)如果在过去6个月有婚姻性行为。我们使用逐步序数逻辑回归模型来确定避孕套使用的相关性。
结果:总计,63.1%(206人中有130人)的夫妇在过去6个月有婚姻性行为,其中89.2%(130个中的116个)一致使用避孕套。婚姻持续时间较长的夫妇(OR=1.15;95%CI:1.03,1.28)更倾向于坚持使用避孕套,而那些缺乏支持和护理(OR=0.25;95%CI:0.07,0.94)和再婚(OR=0.08;95%CI:0.02,0.43)的患者与较少使用避孕套相关.此外,HIV阳性受访者比HIV阴性受访者更有可能发生婚外性行为(p=0.015)。
结论:应考虑HIV阳性配偶的婚外性行为。实施干预措施,例如增加配偶之间的支持和照顾,以促进婚姻的亲密和稳定,可以减少无保护的性行为。
