Negative reproductive health (RH) outcomes appear to be associated with inadequate use of RHrnservices and difference in the use of RH services among different demographic and socioeconomicrngroups. Women beggars are at increased risk of RH problems because of multiple factors. Moreover,rnlittle is known about reproductive health service utilization by those disadvantaged section of thernsociety. Assessing the RH problems of those women and their RH service utilization is critical forrntimely intervention.rnObjective:rnTo assess reproductive health service utilization and associated factors among women beggars in thernreproductive age group in Addis Ababa, Ethiopia.rnMethods:rnA quantitative cross-sectional based study was conducted from September 2015 to May 2016 inrnAddis Ababa. The study was conducted on 351 women beggars of reproductive age group using anrninterviewer administered structured questionnaire. Data were entered in to Epi-Info (version 7) then,rnexported to SPSS (version 20) for cleaning and analysis. Bivariate analysis was used to identifyrnindependent variables that are associated with the outcome variable (RH service utilization). Thosernsignificant variables in the bivariate analysis were taken to multiple logistic regression analysis torndetermine the independent effect of each variable on the outcome variable.rnResults:rnAmong the study participants majority were 35 years or younger (80%), divorced/separated (40.5%)rnand illiterate (64%). About 72% and 29% of women beggars had the first sexual encounter and thernfirst pregnancy, respectively, at the period of adolescence. Women who reported ever use of modernrncontraceptives were 231(65.8%) and those who were using contraceptives at time of data collectionrnwere 130(37%). Forty one (11.7%) of women beggars had history of rape and (36.9%) womenrnencountered unwanted pregnancy at least once in their life time.rnTwo-third (66%) of women beggars reported utilization of reproductive health services. There werernstatistically significant association between reproductive health service utilization and marital status,rnhaving disability and information about reproductive health issues.rnThe odds of reproductive health service utilization among women who were currently unmarriedrn(never married/widowed) was 63% times lower than women who were married [AOR= 0.37(0.19-rn0.72)]. The odds of reproductive health service utilization among women who had disability wasrnabout 60% lower than women who had no disability or chronic illness [(AOR=0.39(0.21-0.74)].Onrnthe other hand reproductive health service utilization by women beggars who had no informationrnabout reproductive health services was 76% times lower than those beggar women who hadrninformation [AOR=0.24(0.13-0.44)].rnConclusions and Recommendation:rnEarly first sexual encounter, early marriage, unintended pregnancy and STI including HIV/ADISrnwere identified as major reproductive health problems of women beggars. Two-third of womenrnbeggars had health service utilization for any reproductive health services. Being disabled and lack ofrnreproductive health service information are strong predictors of non-use of reproductive healthrnservices among women beggars. Increasing/strengthening information provision about reproductivernhealth among women beggars, addressing disability related problems and further researches arernrecommended.rnKey words: RH problems, RH service utilization, women beggars
