HIV/AIDS Research

The research program focuses on treatment, transmission and prevention, and socioeconomic impacts of HIV/AIDS in Africa

HIV/AIDS reaches into every corner of society, affecting parents, children and youth, teachers and health workers, rich and poor. It is  the leading cause of adult death on the African continent. The percentage of adults infected with HIV ranges from 3 or 4 percent in West African countries to as high as 30 percent in regions of southern Africa.

Anti-Retroviral Treatment
Contact: Damien de Walque ( ddewalque@worldbank.org)

The Bank supports several public-private partnerships to accelerate access to antiretroviral treatment (ART) for HIV/AIDS patients in   Burkina Faso, Ghana, and Mozambique. Treatment Acceleration Project (TAP) is working to support the following public-private partnerships:

  • ART delivery through associations of persons living with HIV/AIDS
  • Faith-based organizations
  • Local and international NGOs
  • Partnerships between government hospitals and private health facilities.

The Bank supports antiretroviral treatment delivery in many countries and, in addition to Burkina Faso, Ghana and Mozambique the team is also conducting impact evaluations in India, Kenya, Rwanda and South Africa.[ 1]

Research questions:

  1. What is the impact of treatment on the welfare of patients and family members? This research looks at the impacts on the labor supply of the patient and other family members, the schooling of children, and other welfare indicators.
  2. What are the effects of ART on HIV transmission and prevention? This research looks at the direction (beneficial & adverse) and type (biological & behavior) of effects.
  3. What are the determinants of treatment success?This research looks at how patient care-seeking behavior and treatment adherence, and quantity and quality and of ART services affect treatment success.
  4. What the best ways to encourage cost-effectiveness and capacity building to reinforce the sustainability of ART delivery and adherence? This research uses longitudinal data along with data from biomedical records, household surveys (HIV patients and general population) as well as health facility and surveys to evaluate experiments in Rwanda (performance-based contracting for HIV/AIDS services in health facilities) and South Africa (food supplement and community health workers for supporting adherence to treatment).

 

Transmission and Prevention
Contact: Damien de Walque ( ddewalque@worldbank.org)

This research uses household data such as the Demographic Health Surveys (which includes HIV status of sub-samples of respondents) to better understand the patterns of HIV/AIDS transmission, and the impact of programs designed to affect the incidence of HIV.


 

Socioeconomic Impact
This research investigates the impact of HIV/AIDS on populations, economies and institutions. It also evaluates social protection mechanisms designed to mitigate the impact of the HIV/AIDS epidemic. [ 2]

Marriage Transitions and HIV/AIDS in Malawi
Contact: Kathleen Beegle ( kbeegle@worldbank.org) and Berk Ozler ( bozler@worldbank.org)

The goal of this research project is to collect innovative longitudinal data on a sample of young adults in Malawi to understand the links between non-marital relations and sexual experiences, transitions into marriage, socioeconomic status (both prior to and after marriage), and the spread of HIV/AIDS.

By following a cohort of young adults, the project seeks to understand the socioeconomic and other conditions that precipitate marriage, including early marriages. By continuing to study newly married couples, we will then explore the fertility outcomes and socio-economic consequences associated with marriage, including incidence of HIV/AIDS, and the variation in outcome by the characteristics of marriages.

Specifically, the study will interview 1,000 unmarried women and men in the Mchinji district in Malawi. We will follow them over at least 3 years, continuing to collect detailed socio-economic information, sexual partnering information, and HIV status of respondents and their new spouses. The total amount of funds requested from Hewlett is $140,000. Additional funding will be sought from other sources. The project will produce a publicly-available longitudinal data set and policy-research publications.


 

Schooling, Income, and HIV Risk (Malawi)
Contact: Berk Ozler ( bozler@worldbank.org)

This study investigates the impact of cash transfers, both conditional and unconditional, on schooling, sexual behavior and HIV/STD risk among school-aged women in Malawi (never married women aged 13-22).

The goal is to understand the African context for how CCT programs can best be designed to pull secondary school-age students back into the educational system.  For more on the evaluation design and elaborates on the research questions, estimation strategy, study setting and survey design

Research questions:

What are the health and behavioral benefits from maintaining female enrollment? This question is potentially crucial for African governments that may be considering creating schooling-based conditional cast transfer (CCT) programs.

A multi-arm randomized policy intervention will provide direct experimental evidence on the following questions: 

  • What is the marginal impact of schooling on sexual behavior and HIV/STD risk for young (school-aged) women?
  • What is the income elasticity of (risky) sexual behavior?
  • Are the any negative (or positive) spillover effects of increasing schooling and/or income of some on other young women (young men)?
  • What is the effect of cash transfers on returning to school in Malawi?
