Influencing factors and knowledge related to AIDS among high-risk male population in Chongqing

This study aims to investigate the influencing factors and Acquired Immune Deficiency Syndrome (AIDS) related knowledge among high-risk male population in Chongqing. A total of 388 men who had sex with their fellow men (MSM) and volunteered for counseling or human immunodeficiency virus (HIV) testing in Chongqing were divided into two groups identified as: aware group (n = 299) and unaware group (n = 89). According to the study subjects, the MSM sentinel surveillance questionnaire of the Chinese Center for Disease Control and Prevention was utilized to investigate their AIDS awareness demographic and behavioral characteristics. Univariate analysis was also applied to analyze the influencing factors of their AIDS knowledge. Binary multivariate logistic analysis was further used to screen the independent risk factors of AIDS inadequate knowledge, leading to the use of regression analysis model. Furthermore, hosmer and lemeshow were employed to test the goodness and fitness of the regression analysis model. Finally, SPSS was used to draw receiver operating characteristic (ROC) curves to evaluate the predictive value of the regression analysis model. Among 388 respondents, 299 participants were aware while 89 participants were unaware of AIDS-related knowledge with an overall awareness rate of 77.06%; univariate and multivariate logistic regression analysis showed that education (high school and below) and household registration (other places) were risk factors for AIDS-related knowledge in high-risk male groups in Chongqing. In addition, a probability model predicted high incidence of AIDS in high-risk male groups in Chongqing because of inadequate AIDS knowledge: P = 1/[1 + exp (1.429 − 1.169X2 − 0.969X3)]. The overall level of awareness of AIDS-related knowledge among high-risk male groups in Chongqing was not high because of low education levels (high school or below) and foreign household registration.
