A study by former Harvard fellow Mark McGovern, PhD, along with faculty members David Canning, PhD, and Till Bärnighausen, PhD, and colleagues, has found that efforts to scale up HIV testing through home-based testing are supported by offering a $5 dollar (US) food voucher to residents in South Africa.
A team of HAALSI (a research project studying health of aging population in South Africa) researchers affiliated with the Harvard Pop Center has found that HIV-positive adults in South Africa who receive antiretroviral therapy (ART) for HIV have greater access to preventative care for non-communicable diseases (NCDs) such as diabetes and hypertension. Their findings are published in … Continue reading “Receiving antiretroviral therapy for HIV may offer spillover health benefits for at-risk population in South Africa”
A study published in JAIDS (Journal of Acquired Immune Deficiency Syndromes) by a team of HAALSI (Health and Aging in Africa: A Longitudinal Study of an INDEPTH Community in South Africa) researchers examines whether older adults in rural South Africa have unmet needs for HIV prevention.

The findings … Continue reading “Scaling up male circumcision in Sub-Saharan Africa could prevent more than 1 million HIV infections”
Missing data is a common problem in HIV research due to non-participation in testing, and selection bias can occur if non-participation in testing is associated with HIV status. For example, longitudinal data suggests that individuals who know or suspect that they are HIV positive are less likely to participate in HIV surveys. Four researchers from … Continue reading “How can you statistically correct for missing data and selection bias in HIV prevalence estimates?”
Harvard Pop Center faculty member Till Bärnighausen, MD, has co-authored an article published in Epidemiology in response to a commentary on thier previous study that explores applying regression discontinuity designs in epidemiology published in the September issue of the journal.
Harvard Pop Center PGDA Fellow Mark McGovern, PhD, and faculty member Till Bärnighausen, MD, have co-authored a study published in Epidemiology that explores the usefulness of applying copula functions to the more standard selection model in order to more accurately evaluate HIV prevalence estimates.
Although it is commonly thought that older sexual partners are a major risk factor for HIV for young women in sub-Saharan Africa (and there have been public health campaigns launched to discourage these relationships) in a recent study co-authored by Harvard Pop Center affiliated faculty members Ichiro Kawachi, SV Subramanian, and Till Bärnighausen partner age-disparity … Continue reading “Are older sexual partners a major risk factor for HIV for young women in sub-Saharan Africa?”
Pop Center faculty member Dr. Till Bärnighausen has co-authored a paper in Global Public Health: An International Journal for Research, Policy and Practice entitled “Bringing the state back in: Understanding and validating measures of governments’ political commitment to HIV.”
