Scaling Up Access to Comprehensive Men's Health Services in South African Informal Settlements
This report examines the adoption rates of comprehensive men's health services in South African informal settlements over a 1-year period. Data was collected through structured interviews (n=50) and focused group discussions (FGDs, n=10), supplemented by secondary data from public health records and local government initiatives. Analysis employed descriptive statistics and thematic content analysis to identify key themes and patterns in policy adoption across different settlements. Policy adoption varied significantly across the 12 informal settlements, with a majority of interventions (65%) adopting guidelines within one year, though there were notable variations influenced by local healthcare resources and socio-economic status. Factors such as financial constraints and lack of awareness about services hindered full-scale implementation. Despite challenges, significant progress was made in integrating men's health services into existing healthcare frameworks, with a clear need for targeted interventions to address identified barriers. To accelerate service adoption, it is recommended that local governments collaborate with non-governmental organizations (NGOs) and community leaders to enhance awareness and provide financial support. Additionally, the development of culturally sensitive guidelines tailored to informal settlements' needs should be prioritised.
