Prevalence and associated risk factors of chlamydia and gonorrhoea infections among men who have sex with men in Durban, South Africa.

Despite significant research on the prevalence of STIs in South African men who have sex with men (MSM), recent data on the prevalence and risk factors for curable STI infections among this key populations are limited. This study determined the prevalence of and risk factors associated with Neisseria gonorrhoeae and Chlamydia trachomatis infections among MSM. The sample consisted of 200 MSM resident in Durban. Data were collected using a self-administered questionnaire, and urine samples were collected and tested for N. gonorrhoeae and C. trachomatis. The prevalence of N. gonorrhoeae and C. trachomatis were 3.0% and 6.0%, respectively. Younger age was significantly associated with testing positive for C. trachomatis (p=0.037). Being between the ages of 30-39 years old reduced the risk of acquiring C. trachomatis infection (OR: 0.10, 95% CI: 0.0120-0.7564, p=0.026). In addition, being circumcised reduced the risk of contracting C. trachomatis (adjusted OR: 0.01, 95% CI: 0.0005-0.3516, p=0.01). However, having between 2-4 sex partners increased the risk of testing positive for C. trachomatis (adjusted OR: 107.45, 95% CI: 1.3467-8573.3130, p=0.036). The following factors were significantly associated (p<0.05) with testing positive for N. gonorrhoeae infection: cohabiting with sex partner, engaging in group sex, and drug use. Fear and stigma were the main barriers to accessing health care in the studied population. This study provided evidence of high rates of C. trachomatis infection among MSM resident in Durban. Based on the results, South African MSM, especially the young MSM population, should be given priority when delivering intervention programs to prevent STIs.
