IPUMS Announces Winners of the 2020 Global Health Research Awards

Every year, hundreds of papers are published using DHS Program data. Datasets for individual DHS surveys are available for download from The DHS Program website by completing a simple registration form. Researchers and students can also access the IPUMS DHS data collection to facilitate comparative analysis of DHS Program data. Harmonized across time and space, IPUMS DHS features consistently named and coded variables for 32 African countries and 9 Asian countries, with more datasets constantly being added.

The IPUMS DHS team recently announced the winners of this year’s IPUMS Global Health paper awards, which highlight some of the most exciting research to take advantage of the IPUMS DHS integrated datasets. These papers were selected from a highly competitive field that included nearly 50 studies released in 2020.

The Best IPUMS Global Health Publication Award goes to Zinguang Fan (Department of Sociology, Peking University, Beijing, China) and Maria Vignan Loria (Department of Sociology, University of Washington, Seattle, Washington, USA) for their Demographic Research article, “Intimate Partner Violence and Contraceptive Use in Developing Countries: How Does the Relationship Depend on Context?

Fan and Loria resolve a puzzle in prior research on intimate partner violence (IPV): Why is the relationship between IPV and contraceptive use negative in some countries and positive in others? Using 30 IPUMS DHS samples from 17 countries, the authors demonstrate that the relationship between IPV and family planning is modified by macro contextual factors, including legal prohibitions and national levels of female empowerment. This study stands out not just for answering an important social science question but also in its creative use of the broad range of information collected in DHS Program surveys, including variables on contraceptive use and type, family size preferences, husband-wife disagreement on fertility goals, various indicators of women’s status (e.g., education, employment, decision-making), and domestic violence. In addition, the authors draw on IPUMS DHS variables to determine the direction of causality: from the experience of IPV to increased contraceptive use, rather than from contraceptive use to increased incidence of IPV.

The Best Student Paper Award goes to Siyu Heng (Graduate Group in Applied Mathematics and Computational Science, University of Pennsylvania, Philadelphia, Pennsylvania, USA) and his collaborators Wendy P. O’Meara, Ryan A. Simmons, and Dylan A. Small for their paper, “Relationship between Changing Malaria Burden and Low Birth Weight in sub-Saharan Africa.

This study leverages geographic heterogeneity to determine the effect of reduced malaria burden on low-birth-weight rates across communities in 19 sub-Saharan African countries. Low birth weight is a serious health risk associated with cognitive and physical difficulties among children. This careful and cleverly designed study analyzes IPUMS DHS data from countries with at least two surveys and GPS data on survey cluster locations.  After using optimal matching to pair DHS Program survey clusters separated in time, the authors use a difference-in-difference approach to compare the incidence of low birth weight in areas that did and did not experience malaria decline. Results reveal a substantial decline in low birth weight resulting from declines in malaria prevalence, especially for first-born children.

Congratulations to these scholars on this impressive accomplishment!

IPUMS DHS is a system that makes it easy to find and review thousands of DHS survey variables and to download a single fully harmonized data file with only the variables and samples that interest you. IPUMS DHS currently includes variables from DHS survey samples from 32 African and 9 Asian countries; more samples are constantly being added.

Reflections from the 2020 DHS Fellows Program

The DHS Fellows Program builds the long-term institutional capacity of universities in DHS countries to train students and faculty to analyze DHS data. Since 2011, the DHS Fellows Program has trained more than 150 researchers from over 40 universities in 25 countries in Africa, Asia, and the Middle East. Typically, Fellows attend two separate in-person workshops, prepare publication-quality research papers in teams using DHS datasets, and implement capacity strengthening activities at their home universities.

For the 2020 DHS Fellows Program, a cohort of university faculty from Bangladesh, Burkina Faso, Cameroon, Guinea, Jordan, and Pakistan convened for the first workshop in Nairobi, Kenya, in February 2020. The second workshop, scheduled to begin in April 2020, was canceled due to the COVID-19 pandemic. The DHS Program worked quickly to convert the second workshop into online activities. A remote teaching space was created on The DHS Program Learning Hub with presentations and assignments for the Fellows to complete. Virtual meetings were held with each Fellows team to discuss drafts of their working papers.

The 2020 DHS Fellows produced working papers that addressed a variety of research topics including:

As of this blog’s publication, the teams from Jordan and Cameroon have published their working papers in peer-reviewed journals. Visit The DHS Program Fellows page to see all DHS Fellows’ working papers and publications in peer-reviewed journals.

We interviewed teams of 2020 Fellows from the Asian University for Women in Bangladesh and the Gamal Abdel Nasser University of Conakry in Guinea about the virtual DHS capacity strengthening activities conducted for faculty and students.

Bangladesh

For their working paper, Nazmul Alam, Mohammad Manir Hossain Mollah, and Sharin Shajahan Naomi wrote about the prevalence and determinants of adolescent fertility. They conducted two virtual capacity strengthening sessions via Zoom, one for 21 faculty members, researchers, and development practitioners, and another session for 25 students. In the sessions, the Fellows introduced participants to The DHS Program, reviewed basic characteristics of DHS data, and highlighted how one can effectively generate new ideas from available DHS data without needing to conduct field research, which has become difficult during the COVID-19 pandemic. “Although we were a bit hesitant about the outcome of online sessions, they appeared to be beneficial…faculty members from social sciences, public health, and natural sciences joined…after the workshop, we got very positive feedback.”

Mohammad Manir Hossain Mollah, Sharin Shajahan Naomi, and Nazmul Alam, 2020 DHS Fellows from the Asian University for Women. “We believed that we could deliver the outcome despite the challenges of the pandemic due to our teamwork and mutual understanding.”

Guinea

Bienvenu Salim Camara, Sidikiba Sidibé, and Nafissatou Dioubate wrote about non-use of contraceptives among married women. Days before their planned capacity strengthening presentations, Guinea declared a health emergency due to COVID-19. Universities were closed and gatherings of more than 20 people were prohibited, so the Fellows recorded video presentations introducing The DHS Program survey questionnaires and datasets and uploaded them to Google drive. Students watched the videos at their own pace and emailed the Fellows with questions. Now some students are using DHS data in their research. “One of my students is currently working on his Master’s thesis in maternal health using DHS data, and I am supporting him in the data analysis,” explains Camara. Dioubate notes, “I am proud that I was able to pass on the knowledge gained from the DHS Fellows Program to others and show the opportunities that DHS data can offer.”

Sidikiba Sidibé, Nafissatou Dioubate, and Bienvenu Salim Camara, 2020 DHS Fellows from the Gamal Abdel Nasser University of Conakry. “My favorite part was the capacity building in DHS database analysis. This allowed me to undertake other analyses on nutrition indicators using Guinea datasets (food practices for infants and young children) as well as capacity building activities for my students,” notes Sidibé.

Due to the ongoing COVID-19 pandemic, the DHS Fellows Program was suspended for 2021. In the meantime, take open courses available on The DHS Program Learning Hub and watch for upcoming Workshop and Training Announcements.


DHS Program Analysis Updates: Fall 2020

The DHS Program Research and Analysis team has recently published several studies that analyze new DHS data or employ novel approaches to analyze existing DHS data.

Analysis of New Sickle Cell Data

The 2018 Nigeria DHS includes sickle cell genotyping of a subsample of 11,186 children age 6-59 months, the first population-based household survey to do so at a national level. A new Working Paper, Analysis of Sickle Cell Genotypes of Young Children in Nigeria Using the 2018 DHS Survey, finds that the siblings of genotyped children with sickle cell disease are about 2.5 times as likely to have died as the siblings of other genotyped children. The main value of the data is the description of the spatial distribution of the genotypes within Nigeria. The S and C alleles, which result in sickle cell disease, sickle cell trait, or Hemoglobin C trait, are primarily concentrated in states in the South West Zone, including Lagos, and secondarily in the North Central Zone. This information is helpful for estimating the burden of risk and for prioritizing interventions in different areas of Nigeria.

New Insights Into Wealth Inequality Using DHS Wealth Index Data

DHS surveys include a wealth index, a composite measure calculated using easy-to-collect data on a household’s ownership of selected assets. The DHS wealth index categorizes households into five wealth quintiles. In Household Wealth Relative to Community Wealth: Associations with Specific Asset Ownership and Maternal and Child Health Indicators, researchers computed an additional measure of wealth inequality, calculating a mean wealth score for each sampling cluster. Each household was then categorized according to its wealth relative to the average wealth of the community.

In 9 of 10 countries, households that are poor relative to their communities were more likely to use at least one maternal health care (antenatal care and facility delivery) or vaccination service, suggesting that a household that is poor relative to the community is potentially better able to access the services of a relatively wealthy community. Read the analysis brief for this Analytical Study, a user-friendly summary of the methods, key findings, and relevant action steps. Analysis briefs are available for many recent analytical reports from The DHS Program.

New Analysis of DHS Contraceptive Calendar Data

A new web feature highlights a series of publications that put to new use retrospective, longitudinal data from DHS contraceptive calendars. Three working papers were recently published. In Fertility and Family Planning Characteristics of Contraceptive Clusters in Burundi researchers apply sequence and cluster analysis to identify six discrete clusters that characterize women’s dynamic contraceptive and pregnancy behaviors over the previous five years. Factors most consistently associated with cluster membership are the need for family planning, lifetime experience of contraceptive use, marital status, pregnancy experience, and age.

Additionally, two working papers, Associations between Women’s Current Contraceptive Method Decision Making and their Reproductive Calendar Histories in Burundi, and Attributes Associated with Women’s Contraceptive Profiles in Burundi: Knowledge, Attitudes, and Interactions with Media and Health Services, further explore two “Family Builder” clusters. Women from the Family Builder 1 cluster had higher relative risks of deciding jointly whether or not to use contraception with their partners or husbands than of not deciding about contraception. Moreover, both “Family Builder” clusters are characterized by the presence and differences in the timing of multiple pregnancies in their calendar histories. Women with high contraceptive knowledge, intentions to use contraception, and well-articulated family size ideals are characteristic of Family Builder 1, while low contraceptive knowledge, no use of contraception, and vague family size preferences are characteristic of Family Builder 2. These results can guide reproductive health programs as they target interventions to the unique subpopulations they seek to serve.

DHS Program Analysis Updates: Summer 2020

The DHS Program’s analysis team uses DHS data to explore topics related to global health, demography, and social epidemiology. Since our last update, the analysis team has used DHS data to explore the following questions:

Modern Mother is one of six profiles of women’s contraceptive and pregnancy behaviors in Nepal.
A Bayesian geospatial modelling approach generates subnational estimates of stunting and wasting in Mali, and identifies key factors associated with undernutrition.

Follow The DHS Program on Twitter and Facebook for updates when new analysis publications are published later this summer!
