  1. The prevalence of UAI-RP among couple participants of insertive role and receptive role were the same, so the insertive role’s actor/partner effects were equivalent with receptive role’s partner/actor effects
  2. AOR: adjusted odds ratio, adjusting for background variables which were significant or marginally significant in association with UAI:
  3. a Only UAI with regular partner: monthly income, relationship length, used condoms during their first sexual intercourse, had sexual agreement;
  4. b Concurrent UAI: currently a student, sexual orientation, substance abuse, used condoms during their first sexual intercourse, type of the relationship, had sexual agreement, had multiple regular partners
  5. P < 0.10; *P < 0.05; **P < 0.01; Statistically significant results were bolded
