Assessing the role of anal intercourse in the epidemiology of AIDS in Africa
We aimed to determine how common and frequent heterosexual AI is in South Africa. Stratified random-effects meta-analysis by sub-groups was used to produce pooled estimates and assess the influence of participant and study characteristics on AI prevalence. Results : Of 41 included studies, 31 reported on AI prevalence and 14 on frequency, over various recall periods. AI prevalence was high across different recall periods for sexually active general-risk populations e. Prevalence was higher in studies using more confidential interview methods.
Metrics details. Oral and anal sexual behaviours are increasingly reported among adolescents and adults reporting heterosexual sex in peer-reviewed journals in high income countries, but less is known about these behaviours in low and middle-income countries, especially in sub-Saharan Africa.
