Background: Examining the non-communicable disease (NCD) profile for South Africa (SA) is crucial when developing health interventions that aim to reduce the burden of NCDs.
Objective: To review NCD indicators in national data sources in order to describe the burden of NCDs in SA, using hypertension as an example.
Methods: Age, gender, district of death and underlying cause of death data were obtained for 2008 and 2009 mortality unit records from Statistics SA and adjusted using STATA 11.
Objective: To evaluate the safety of combination antiretroviral therapy (ART) in conception and pregnancy in different health systems.
Design: A pilot ART registry to measure the prevalence of birth defects and adverse pregnancy outcomes in South Africa and Zambia.
Methods: HIV-infected pregnant women on ART prior to conception were enrolled until delivery, and their infants were followed until 1 year old.
Background: Mobile HIV screening may facilitate early HIV diagnosis. Our objective was to examine the cost-effectiveness of adding a mobile screening unit to current medical facility-based HIV testing in Cape Town, South Africa.
Methods And Findings: We used the Cost Effectiveness of Preventing AIDS Complications International (CEPAC-I) computer simulation model to evaluate two HIV screening strategies in Cape Town: 1) medical facility-based testing (the current standard of care) and 2) addition of a mobile HIV-testing unit intervention in the same community.
Background: HIV counseling and testing may serve as an entry point for non-communicable disease screening.
Objectives: To determine the yield of newly-diagnosed HIV, tuberculosis (TB) symptoms, diabetes and hypertension, and to assess CD4 count testing, linkage to care as well as correlates of linkage and barriers to care from a mobile testing unit.
Methods: A mobile unit provided screening for HIV, TB symptoms, diabetes and hypertension in Cape Town, South Africa between March 2010 and September 2011.
