OBJECTIVE: To provide information on trends on official development assistance (ODA) disbursement patterns for reproductive health activities in 18 conflict-affected countries. DESIGN: Secondary data analysis. SAMPLE: 18 conflict-affected countries and 36 non-conflict-affected countries. METHODS: The Creditor Reporting System (CRS) database was analyzed for ODA disbursement for direct and indirect reproductive health activities to 18 conflict-affected countries (2002-2011). A comparative analysis was also made with 36 non-conflict-affected counties in the same 'least-developed' income category. Multivariate regression analyses examined associations between conflict status and reproductive health ODA and between reproductive needs and ODA disbursements. MAIN OUTCOME MEASURES: Patterns of ODA disbursements (constant U.S. dollars) for reproductive health activities. RESULTS: The average annual ODA disbursed for reproductive health to 18 conflict-affected countries from 2002 to 2011 was US$ 1.93 per person per year. There was an increase of 298% in ODA for reproductive health activities to the conflict-affected countries between 2002 and 2011; 56% of this increase was due to increases in HIV/AIDS funding. The average annual per capita reproductive health ODA disbursed to least-developed non-conflict-affected countries was 57% higher than to least-developed conflict-affected countries. Regression analyses confirmed disparities in ODA to and between conflict-affected countries. CONCLUSIONS: Despite increases in ODA for reproductive health for conflict-affected countries (albeit largely for HIV/AIDS activities), considerable disparities remains. TWEETABLE ABSTRACT: Study tracking 10 years of aid for reproductive aid shows major disparities for conflict-affected countries.
