ABSTRACT

Objective To describe the characteristics of newly reported HIV/AIDS cases via non-marital or non-commercial heterosexual transmission and to find out the relative factors in Hangzhou,from 2015 to 2017.Methods Data were collected through the national HIV/AIDS comprehensive control and prevention data system.Study subjects would include those reported HIV/AIDS cases who were residents of Hangzhou and were infected via non-marital heterosexual transmission,between January 1,2015 and December 31,2017.Demographic characteristics and behavioral information were collected.x2 test was used to compare different characteristics of the non-married heterosexual transmission subjects.Logistic regression was used to assess factors that associated with non-marital but non-commercial HIV heterosexual transmission with SPSS.20 software used to analyze statistically.Results Non-marital HIV heterosexual transmission accounted for 38.03％ (1 393/3 663) of the total new reported HIV/AIDS cases in 2015-2017.Out of the 1 393 HIV/AIDS cases,those infected through non-marital but non-commercial heterosexual transmission accounted for 50.83％ (708/1 393),and those through non-martial commercial transmission was accounted for 49.17％ (685/1 393).Male to female ratio was 3.51 ∶ 1 (1 084/309).Male HIV cases reported that their major way of infection was via non-marital commercial transmission (670/1 084,61.81％),while female patients reported the way was via non-marital non-commercial (294/309,95.1％).Results from multivariate logistic analysis showed that the related risk factors and ORs for non-marital but non-commercial transmission appeared asfemale (aOR=48.25,95％ CI26.94-88.44),＜30 year olds (aOR=2.43,95％CI1.3 1-4.5 1),30-39 year olds (aOR=1.92,95％CI1.11-3.33),40-49 year olds (aOR=1.80,95％ CI1.08-3.00),married or unmarried (vs.divorced or widowed,aOR=1.57,95％CI1.10-2.24;aOR=1.78,95％CI1.15-2.78),high school and above of education level (vs.primary school and under of education level,aOR=1.82,95％ CI1.18-2.80),administrative officers or employee (vs.farmers,aOR=2.03,95％ CI1.04-l.91).Number of non-marital partners less than 5 (vs.number of non-marital partners more than 5,aOR=10.65,95％CI6.41-17.42).Conclusions HIV/AIDS cases with non-marital heterosexual transmission accounted for considerable proportion regarding the HIV transmission in Hangzhou from 2015 to 2017.Differences were found in the following factors as non-marital and non-commercial heterosexual transmission with diverse gender,age,marital status,educational level and occupation among of the HIV/AIDS patients.
