Love moderates the relationship between partner type and condom use among women engaging in transactional vaginal sex

Background Relationship characteristics and day-to-day variation in affective state have been associated with HIV risk behaviour. However, no research has assessed the impact of these factors on event-level condom use among women engaging in transactional sex. Methods: Twenty-six women engaging in transactional sex were enrolled in a prospective study of their sexual health. They completed diaries about multi-level predictors of condom use during vaginal sex twice, daily. Results: Over 4 weeks, 18 participants reported 87 paid/traded vaginal intercourse events. Of these, 51.7% were condom protected. The majority of paid/traded events (81.5%) occurred with a non-romantic partner. After controlling for partner type, feeling in love on a given day was associated with higher odds of condom use during paid/traded sexual events, while having sex on the weekend and at night were associated with lower odds of condom use (all P≤0.05). There was a significant interaction between being in love and using condoms during transactional sex (P<0.01). In paid/traded sexual events with romantic partners, the frequency of condom use was 71.4% (5/7) when women did not report love and 40% (4/10) when love was reported. In sexual events with non-romantic partners, the frequency of condom use was 43.8% (14/32) when women did not report love and 59.5% (22/37) when love was reported. Conclusions: Women were less likely to report protected sex with romantic partners and more likely to report protected sex with non-romantic partners when they are in love. Interventions focusing on the link between day-to-day variation in affective state on condom use may help women with risk management across partner types.
