Background: The influx of over 1.3 million refugees in Uganda, with over 10% settling in the capital city Kampala, challenges the ability of urban refugees to access Sexual and Reproductive Health services (SRH) and family planning (FP) amidst the multiple uncertainties of a precarious everyday life. Utilization of SRH services remains low among urban refugees despite the fact that these services are essential to those of reproductive age and vulnerable to unwanted pregnancies and its consequences and contracting sexually transmitted infections (STIs) including HIV. Mildmay Uganda conducted a multimethod outreach program to establish the predictors of access to SRH services by urban refugees in Kampala city. This paper reports on social demographic characteristics that influenced the uptake of SRH services by urban refugees.Methods: A participatory, gender based, community-led, empowerment approach known as Gender Action Learning Systems (GALS) was employed to deliver SRH including family planning services to urban refugees in Kampala between March 2018 and September 2019. Urban refugees enrolled in GALS were interviewed at the beginning and end of the GALS intervention, where both qualitative and quantitative data were collected. Univariate, bivariate, and multivariate analyses were conducted to determine social demographic factors influencing the uptake of SRH services by urban refugees.Results: The​ ​study enrolled 867 participants, with 605 remaining to the end. Median age was 29 (IQR:22-36) years with a standard deviation of 10.7, 52% of the participants had never married. Retention in the study of the sexually active age cohort of primary interest (15 -34) was higher than the 35-54 cohort for both men and women. There were significant associations between SRH use and age, religion and education level among the urban refugees. Pentecostal religion (Adjusted OR 7.9; 3.5-18) and education level of primary (Adjusted OR 3.4; 1.1-11) were associated with uptake of SRH and FP. Conclusion: The participatory, peer-led community approach to delivering SRH services to urban refugees in this research project boosted uptake by the refugees and supported its successful completion and ability to address previously unknown predictors. A continuous awareness campaign using tested models such as GALS to promote services to refugees is needed to successfully integrate newcomers into Uganda’s general healthcare services.
