[Characteristics of newly reported HIV/AIDS cases with non-marital or non-commercial heterosexual transmission in Guangxi Zhuang Autonomous Region, 2015-2018].

To understand the characteristics and associated factors of newly reported HIV/AIDS cases with non-marital or non-commercial heterosexual transmission, in Guangxi Zhuang Autonomous Region (Guangxi), 2015-2018. Information of newly reported HIV/AIDS cases aged ≥18 years in Guangxi between 2015 and 2018 was collected from the National Comprehensive HIV/AIDS Information System. Unconditional logistic regression model was used to access those factors that were associated with HIV infections through non-marital or non-commercial heterosexual contact. Between 2015 and 2018, a total number of 35 497 HIV/AIDS cases, aged ≥18 years were newly reported in Guangxi. Among them, 32 648 (92.0) were infected heterosexually while 10 500 were infected through non-marital or non-commercial heterosexual behavior. Non-marital or non-commercial heterosexual transmission accounted for 29.6 (10 500/35 497) of the newly reported HIV/AIDS cases, and 32.2 (10 500/32 648) of those with heterosexual transmission. Males counted for 53.5 (5 617/10 500) of non-marital or non-commercial heterosexual transmission and males to females ratio was 1.2∶1 (5 617∶4 883). Those married or had regular sexual partners counted for 55.9 (5 873/10 500). Commercial heterosexual transmission appeared the main mode of HIV transmission for males (64.4,16 516/25 633) while main mode for females was non-marital or non-commercial heterosexual transmission and counted for 49.5 (4 883/9 864). Results from the multivariate logistic regression analysis showed that adjusted of female HIV/AIDS infected HIV via non-marital or non-commercial heterosexual transmission, was 3.98 times (95: 3.78-4.20) hight than that of males. Among the group aged<50 years and the aged 50-59 years, the adjusted s were 1.35 times (95: 1.27-1.44) and 1.13 times (95: 1.05-1.21) hight than that of aged ≥60 years. Those who were single/divorced/widowed, the adjusted was 1.53 times (95: 1.45-1.61) hight than that of those married/regular partners. Those with junior high school education, high school education and above the adjusted s were 1.22 times (95: 1.16-1.29) and 1.18 times (95: 1.10-1.27), compared to those only with education levels of primary school or below. The number of HIV/AIDS cases via non-marital or non-commercial heterosexual transmission accounted for nearly 30.0 of all the routes of HIV transmission in Guangxi, 2015-2018. Female, aged<60 years old, single/divorced/widowed and having had junior and above high school education ., appeared as risk factors on non-marital or non-commercial heterosexual transmission, among newly reported HIV/AIDS in Guangxi.
