Scaling up male circumcision in Sub-Saharan Africa could prevent more than 1 million HIV infections

Till BärnighausenHarvard Pop Center faculty members Till Bärnighausen, ScD, MD, PhD, and David Bloom, PhD, are co-authors of a new paper written for the 2015 Copenhagen Consensus that touts scaling up male circumcision to include 90% of Sub-Saharan males who are not HIV infected as a way to cost-effectively and dramatically reduce HIV infections. The findings of the paper, which also include expanding anti-retroviral treatment (ART), are featured in a news story on the Harvard T.H. Chan School of Public Health website.

How can you statistically correct for missing data and selection bias in HIV prevalence estimates?

Mark McGovernMissing 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 Harvard Pop Center, including Mark McGovern, PhD, Till Bärnighausen, MD, Joshua Salomon, PhD,  and David Canning, PhD, have published a study in BMC Medical Research Methodology that explores a practical and easy-to-implement method to correct for selection bias in HIV prevalence estimates.

Till BärnighausenHarvard 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.

New approach for estimating HIV prevalence

Mark McGovern 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.

Are older sexual partners a major risk factor for HIV for young women in sub-Saharan Africa?

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 did not predict HIV acquisition amongst young women.
