Abstract：
To investigate sexual behaviours among HIV-discordant heterosexual couples and assess the correlates of condom use at the couple level.
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.

摘要：
目的：调查HIV不和谐异性恋夫妇的性行为，并评估夫妇使用避孕套的相关性。
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。
