[Analysis of high-risk sexual behaviors and related factors among HIV-infected men who have sex with men aged 18-24 years before and after diagnosis of HIV infection in Shandong Province].

Objective

To explore characteristics and related factors of high-risk sexual behaviors of HIV-infected MSM aged 18-24 years before and after diagnosis of HIV infection in Shandong Province, and to provide a reference basis for formulating targeted behavioral intervention strategies and measures for young HIV-infected MSM.

Methods

From September 2023 to December 2024, MSM-affected individuals aged 18 to 24 years were recruited as research subjects in Qingdao City, Weifang City, and Linyi City, which have reported relatively large numbers of HIV-infected individuals in Shandong Province, and face-to-face questionnaire surveys were conducted. The logistic regression model was used to analyze the related factors of high-risk sexual behaviors after confirmation in MSM infected individuals. EpiData 3.1 software was used to establish the database, and SPSS 22.0 software was used for data collation and statistical analysis.

Results

Before and after diagnosis of HIV infection of 190 HIV-infected MSM aged 18-24 years, the proportion of those with ≥2 houmosexual partners decreased from 82.11% (156/190) to 39.47% (75/190), and the proportion of those who engaged in unprotected sexual behavior decreased from 93.09% (175/188) to 39.36% (74/188). The results of the multivariate logistic regression model analysis showed that the positive related factors for unprotected sexual behavior in HIV-infected MSM after diagnosis of HIV infection included a per capita monthly income of the family <2 000 yuan (aOR=5.19, 95%CI:1.49-18.03), and the way of seeking homosexual partners after diagnosis of HIV infection was online (aOR=8.87,95%CI: 1.13-69.45), both online and offline methods were available (aOR=38.55, 95%CI: 4.47-332.87). The positive related factors for multiple sexual partner behavior after diagnosis of HIV infection of HIV-infected MSM include the use of new types drugs (aOR=2.62, 95%CI: 1.24-5.53) and failure to inform others of one's HIV infection status (aOR=2.41,95%CI:1.26-4.61), the number of same-sex sexual partners before confirmation was ≥2 (aOR=3.72, 95%CI:1.40-9.93), the type of sexual partner before confirmation was temporary (aOR=2.98, 95%CI:1.52-5.82).

Conclusions

In Shandong Province, after diagnosis of HIV infection, HIV-infected MSM aged 18 to 24 years still have the phenomenon of unprotected sexual behavior and multiple sexual partner behavior, and the risk of HIV transmission was relatively high. In the management and service work for people infected with HIV, it is necessary to strengthen the publicity of laws and policies, increase the awareness rate of the rights and obligations of people infected with HIV, reduce their high-risk sexual behaviors, and lower the risk of HIV transmission.
