A team of researchers affiliated with the Harvard Pop Center and the Health and Aging in Africa: A Longitudinal Study of an INDEPTH Community in South Africa (HAALSI) has found that the self-reported HIV status of older adults was accurate enough that it could be considered as a routine first step to establish HIV status when … Continue reading “In South Africa, when HIV testing is not always possible, is self-reported status a viable, reliable alternative?”
A study just out in the Journal of Hypertension co-authored by Harvard Pop Center faculty members Stephen Tollman, Till Bärnighausen, Joshua Salomon, and Bell Fellow Xavier Gomez-Olive points to the potential effectiveness of a local, long-term health surveillance program for managing hypertension, the leading risk factor for cardiovascular disease. The results of the study shed light … Continue reading “Hypertension well managed for those older South Africans whose health was monitored by long-term surveillance program”
A study published in the American Journal of Public Health by Harvard Pop Center faculty members Jessica Cohen, PhD, Joshua A. Salomon, PhD, and Günther Fink, PhD, along with lead author Slawa Rokicki, reveals that text-messaging programs can be an effective vehicle through which to increase reproductive health knowledge and reduce pregnancy risk among sexually active adolescent girls … Continue reading “Text messages can boost knowledge and help reduce adolescent pregnancy risk in LMICs”
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.
Pop Center faculty members Amitabh Chandra, PhD, Ashish Jha, MD, Ichiro Kawachi, MD, PhD, Joshua Salomon, PhD, SV Subramanian, PhD, and David Williams, PhD, are among the Harvard scholars cited on health inequalities in this Harvard Gazette article, the fourth in a series on what Harvard scholars are doing to address inequality in the United … Continue reading “Pop Center faculty share insights into U.S. health inequalities in Harvard Gazette’s series on inequality”
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?”
Research by Joshua Salomon, Pop Center faculty member, on the State of the US Health, 1990-2010: Burden of Diseases, Injuries, and Risk Factors, recently published in JAMA, finds the US is making progress in improving health but not keeping pace with other wealthy nations.
