2 out of 3 of those aged 25–29. Although prevalence is higher among women in general, only 1 in every 6 HIV/AIDS infected people with multiple sex partners are women. According to a study published in late 2019, men who have sex with men (MSM) are at higher risk of HIV infection than men in the general population. Prevalence rates of HIV infection among MSM varied from 6 to 37% depending on the country, far exceeding the national prevalence rates. The prevalence ratios are particularly elevated in West and Central Africa as well as in low-prevalence countries. Young boys and girls in South Africa are both highly affected by intimate partner violence and HIV/AIDS. Research has found links between the two, as well as a relationship with drug use. It was found that problem drinking and marijuana use are mediating variables in the relationship between men who experienced childhood sexual abuse and who engage in HIV sexual risk behaviors. One 2006 study also noted that alcohol and increased HIV risk are linked to gender-based violence in two specific ways - one being that the consumption of alcohol might lead to increased sexual violence against women refusing sex, and that women may be abused for disclosing their positive status to their partner. In adult and adolescent women, low relationship power and victimization by intimate partner violence were found to be linked to HIV risk. This lower relationship power affects interpersonal dynamics that increase sexual risk due to condom nonuse and the likelihood of a girl with low relationship power having more sexual partners. However, both boys and girls with lower relationship power were found to be more likely to have multiple partners. Regardless of gender, youths with lower power are more vulnerable to be pressured or coerced into transactional sex. Furthermore, women and men both experience difficulty disclosing their HIV positive status for various reasons, the most common of which being that women fear abandonment or retaliative violence, while men fear embarrassment and shame. By pregnant women HIV prevalence among pregnant women is highest in the populous KwaZulu-Natal province (37%), and lowest in the Western Cape (13%), Northern Cape (16%) and Limpopo (18%) provinces. In the five other provinces (Eastern Cape, Free State, Gauteng, Mpumalanga and North West) at least 26% of women attending antenatal clinics in 2006 tested HIV-positive. The latest HIV data collected at antenatal clinics suggest that HIV
