U.S. fertility rates are at an all-time low, partially due to delayed parenthood, increased childlessness, fewer unplanned teenage pregnancies, and declines in immigration. As explained by Hans-Peter Kohler, Pilar Gonalons-Pons, and Emilio Alberto Parrado in Penn Today, the drop isn’t cause for alarm but does bring to light questions about work, family, and immigration policies that can affect population growth.
Hans-Peter Kohler, PSC & PARC research associate, discusses the recent decline in U.S. birth rates on a Marketplace podcast. “At the level we are observing it in the U.S., it is not a problem. If the U.S. had South Korean, Japanese, or Italian fertility rates, arguably, the pressure to do something about this might be higher,” says Kohler.
LDI Senior Fellows Douglas Wiebe and Mitesh Patel of the Perelman School of Medicine and Hans-Peter Kohler of the School of Arts and Sciences are using pilot grants to test concepts ranging from the support of Philadelphia's effort to launch the first safe injection site to the effect of survival perceptions on HIV patients and the change of physician behavior.

During the past 20 years, Hans-Peter Kohler of the School of Arts and Sciences has investigated how social, epidemiological and demographic factors affect people in Malawi. His is a rare example of a longitudinal study focused on a population in a low-income nation that has had to confront stressors like famine and AIDS. Read the Omnia article here.
This week Victor Mwapasa and Chiwoza Bandawe from the University of Malawi College of Medicine visited the University of Pennsylvania. Hans-Peter and Iliana Kohler have written with Victor and Chiwoza about the Malawi Longitudinal Study of Families and Health for several years. The group's research has focused on the relationship between HIV prevalance, transmission and disclosure and family health. Recently Hans-Peter, Iliana, Chiwoza, and Colin Payne authored a paper about the Demography of Mental Health Among Mature Adults in a Low-Income, High-HIV-Prevalence Context. This summer a team of researchers including Penn PhD students went to Malawi to train and do data collection. The collaborators will meet on Friday to discuss current research and the PSC coud not be more pleased to host them.
Global Family Change
A few weeks ago Hans-Peter Kohler (PI) and Frank Furstenberg (Co-PI) embarked on a journey to better understand the complex ways in which families are changing across the world. Global Family Change (GFC) is an NSF funded project that will explore how families change on a global scale and will build a wealth of data to share. If you weren't able to make it to Luca Maria Pesando's, talk "Global Family Change: The Reshaping of Society's Most Fundamental Institution with Development" last week you are in luck! The presentation, followed by a lively discussion, is now available on our YouTube channel.

In July, Hans-Peter Kohler presented in the UK House of Lords in an event organized by the UK All-Party Parliamentary Group on Population, Development and Reproductive Health (APPG). The event was a celebration of the 2015 World Population Day and the release of the 2015 APPG Report on Population Dynamics and the Sustainable Development Goals.

Hans-Peter Kohler (in collaboration with Ayesha Kharsany at the Centre for the AIDS Programme of Research in South Africa [CAPRISA]), recently received a 5yr NIH R01 Grant for "Identifying sources of HIV infection in adolescent girls in rural South Africa". The aim of this project is to utilize an innovative approach to identify networks of HIV transmission, combining extensive epidemiologic sampling with phylogenetic analyses of HIV-1 sequence data and traditional sexual networking methods. Insights into the sexual networking patterns driving high HIV incidence in adolescent girls in rural South Africa could be critical for informing future design of HIV prevention interventions.

Hans-Peter Kohler and Jere R. Behrman participated in the Rethink HIV project by the Copenhagen Consensus Center and the Rush Foundation that focused on identifying effective interventions in the fight against HIV/Aids across sub-Saharan Africa. Their assessment paper for the prevention of the sexual transmission of HIV was the basis of the policy recommendations in this area.
