  3. Clinical Trial HPTN 052 • There was a relative reduction of 96% in the number of linked HIV-1 transmissions • Early antiretroviral therapy reduced sexual transmission and clinical events • The results indicate both personal and public health benefits

  4. Problem Statement • The number of new infections and deaths have declined between 15-30%. • An estimated 14 million people are receiving life-saving anti-retroviral treatment (ART). • The world has experienced a widespread of preventive services. • Millions of orphans in poor countries have been provided with education and health care. • Evidence of the impact of HIV investments on health outcomes, based on empirical analysis, is almost non-existent

  5. HIV investments are increasing while new HIV infections have fallen globally New HIV infections Global, 2001-2012 Annual HIV and AIDS investments

  6. Objective and Methods • Objectives: to examine the relationship between investments andHIV incidence as well as AIDS mortality. • Design: Panel data analysis including 63 low- and middle-income countries or 230 country-years data points from 2005 to 2012. • Data Sources: we used publicly available data including: HIV incidence, mortality, HDI, GDP and governance indicators from the World Bank.

  7. Methods – II - Analysis • The common problems typical for panel data such as autocorrelation, stationary of time series and heteroscedasticity were examined carefully. • Fixed and Random Effect models were fitted to analyze association between HIV investments on incidence and mortality. • Dynamic panel specifications were explored and estimated by instrumental variables methods

  8. Findings from panel data analysis Estimated effect of investments on AIDS-deaths • Hausman test suggest that FE model is more appropriate.

  9. Estimated effect of investments on HIV-incidence *Using GNI as Instrumental Variable

  10. Summary • International and domestic investments have a beneficial and statistically significant effect on AIDS mortality • Doubling per capita HIV/AIDS expenditures is associated with a 6% reduction in the AIDS mortality rate. • A 10% increase in HIV spending in the previous year is associated with reduction of 0.15% HIV incidence in the current year. • For the average country in Sub-Saharan Africa, increasing per capita HIV and AIDS investments by US$12 per year is associated with 250,000 fewer AIDS-related deaths or a 20% reduction.

  11. Conclusions • Investments in HIV and AIDS are paying off by reducing new infections and mortality • The estimated effect is small, reflect past resource use and allocation and it is only marginal to other non- measured benefits • Looking forward, the resources needed should be lower, if future efficiencies and targeted responses replace wide investments made during the emergency phase of the global response
