We use data from a randomized controlled trial in Ethiopia and examine the causal effects of HIV/AIDS education, home-based voluntary HIV counseling and testing (VCT), and conditional cash transfers (CCT) for facility-based VCT on HIV/AIDS knowledge and demand for HIV testing. HIV/AIDS education significantly increases HIV/AIDS knowledge but has a limited effect on testing take-up. However, when HIV/AIDS education is combined with either home-based VCT or CCT for facility-based VCT, take-up increases substantially by about 63 and 57 percentage points, respectively. We also demonstrate evidence of persistence in test-taking behavior, where past HIV testing does not dampen demand for testing. Lastly, we find suggestive evidence that home-based VCT could be more effective at detecting HIV-positive cases relative to CCT for facility-based VCT. Our findings highlight the importance of geographic accessibility in the testing decision and persistence in demand for HIV testing. Copyright © 2016 John Wiley & Sons, Ltd.

Background: Risk of anal cancer is high in certain populations and screening involves collection of anal swabs for HPV DNA and/or cytology testing. However, barriers exist, such as the need for an intimate examination, and stigma around HIV status, sexual orientation, and sexual practices. Self-collected anal swabs (SCA) are a proposed alternative to clinician-collected swabs (CCA) to overcome these barriers.

Background: The prevalence of dementia in low- and middle-income countries is increasing, yet epidemiological data from African populations remains scarce. Crucial risk factors differ in Africa from more intensively studied global areas, including a high burden of cerebrovascular disease (evidenced by high stroke incidence) and HIV, but lower rates of other risk factors such as physical inactivity. In the pre-antiretroviral therapy era, dementia was a common consequence of HIV infection.

University of Michigan, Ann Arbor, MI, USA.
Background: In Zambia, dementia prevalence is unknown due to limited community awareness and a lack of providers skilled in recognizing and diagnosing this disease. Community healthcare workers (CHWs) are widely utilized across sub-Saharan Africa to improve health care access, particularly HIV services. CHWs may be an untapped resource to raise awareness, screen for dementia, and support dementia care in the community.
