[Status of marriage and HIV transmission between couples in newly reported HIV cases before diagnosis was made, among men who have sex with men in China, 2014].

To analyze the status of marriage and HIV transmission between couples in newly reported HIV cases before diagnoses were made, among men who have sex with men (MSM) in China. Baseline and follow-up information related to newly reported cases in 2014 were collected from the Chinese HIV/AIDS Comprehensive Response Information Management System. Infected MSM who were older than 22 years of age were included in this study. HIV cases were divided into sero-concordant or sero-discordant group, according to the HIV status of the couple who were tested 180 days post-diagnosis. Multivariate logistic regression method was used to analyze the potential factors associated with HIV transmission between couples before diagnosis was made. A total of 5 081 (22.7) of the HIV infected MSM who had couples, were included in this study. A total of 3 715 cases had their couples tested 180 days after the diagnosis was made. 7.6 (282) had positive couples. Results from the multivariate logistic regression analysis showed that factors as: older than 60 (=2.64, 95: 1.50-4.65) years of age, being minorities (=1.93, 95: 1.13-3.29), having CD(4)(+)T cells less than 500 cells/μl (<200: =2.91, 95: 1.82-4.65; 200-349: =1.98, 95: 1.22-3.23; 350-500: =1.69, 95: 1.00-2.86), with self-reported unsafe behaviors (=1.92, 95: 1.44-2.58) , were more likely to transmit HIV to their couples before the diagnosis was made. Behavior interventions and early HIV testing should be promoted, especially among those MSM who had couples, to avoid inter-spousal transmission.
