Abstract:
Objective:To study the prevalence and correlates of unprotected sexual intercourse within HIV serodiscordant couples in Dehong prefecture, Yunnan Province, China, in 2014.
Methods:This study was based on the follow-up investigation of "the AIDS cohort of seronegative spouses of HIV-infected individuals in Dehong prefecture" in 2014. The 1 520 participants were HIV seronegative spouses from all five counties/cities of Dehong prefecture who voluntarily participated in the cohort. Inclusion criteria included: having a HIV-positive spouse; ≥16 years of age; having had sexual intercourse with spouse in the past year; and being a resident of Dehong prefecture. Information on HIV-positive spouses were also collected through the local AIDS epidemic database. Chi square analysis was performed to compare differences in the rates of unprotected sexual intercourse between participants with different characteristics and lifestyle choices. Multivariable logistic regression model analysis was performed to determine correlates with unprotected sexual intercourse.
Results:The 1 520 participants had a mean age of 38.7±9.4, compared with 39.7±8.9 for their HIV-positive spouses. Among the HIV-positive spouses, 77.8% (1 183/1 520) had been infected for more than 3 years, and 87.6% (1 332/1 520) had received antiretroviral therapy. The prevalence of unprotected sexual intercourse within serodiscordant couples over the past 12 months was 16.1% (244/1 520). The prevalence of unprotected sexual intercourse correlated with the level of education of HIV-negative spouses (illiterate vs. middle school and above, OR=1.58, P=0.044), the number of years since diagnosis of HIV-positive spouses (short vs. long, OR=1.6, P=0.006), antiretroviral therapy of HIV-positive spouses (no vs. yes, OR=2.78, P<0.001), the frequency of sexual intercourse per month (high vs. low, OR=1.66, P=0.019), and whether the couple had children (no vs. yes, OR=1.72, P=0.007).
Conclusion:The prevalence of unprotected sexual intercourse within serodiscordant couples in Dehong prefecture was relatively high in 2014. Factors found to correlate with the occurrence of unprotected sexual intercourse within these couples included illiteracy of HIV-negative spouses, short time since diagnosis of HIV-positive spouses and lack of antiretroviral therapy, high frequency of sexual intercourse and no children.
