Background: One component of post abortion care is preventing repeat abortions by providingrnfamily planning counseling and contraception. Provision of long-acting reversible contraceptivernmethods has a higher potential to interrupt the continuous cycle between abortion and unplannedrnpregnancies that result in reduction of maternal morbidity and mortality. rnObjective: To assess utilization of long acting reversible contraceptive and associated factorsrnamong women who receive abortion service in Hawassa public health facilities, southernrnEthiopia. rnMethods: Facility based cross-sectional study design using quantitative method wasrnimplemented in Hawassa public health facilities, southern Ethiopia. Three hundred ninety sixrnstudy participants were included and proportionally allocated to the two public hospitals and 4rnpublic health centers. The data was collected by interview using pretested structuredrnquestionnaire. Data entry was done using Epidata 3.1 version then data was cleaned and exportrnto SPSS for data analysis. Frequency and median were displayed through tables and words.rnBivariate and multivariable logistic regressions were used to analyze the association factors ofrnthe dependent variable using odd ratio and 95% confidence interval. P value < 0.05 during multirnvariable analysis considered as significance. rnResult: A total of 396 women came to the facility for abortion services were interviewed in thisrnstudy with 96.4% of response rate. The overall utilization of long acting reversible contraceptivernwas 20.5% [16.4-24.8]. Decision making by both partners on long acting reversible contraceptivernmethods (AOR=3.3; 95% CI [1.56-7.09]), history of abortion (AOR=3.93; 95% CI [1.48-10.4]),rncounseling on family planning after abortion procedure (AOR=3.01; 95% CI [1.43-6.33]) andrngrand multiparous (AOR=6.68; 95% CI [2.28-19.5]) were associated with post abortion longrnacting reversible contraceptive utilization. rnConclusion: Parity, previous abortion history, partners a companion decision making and timernof counseling had significant association with post abortion long acting reversible contraceptivernutilization. Programs that support male involvement should be supported and initiated to improvernfamily planning utilization among abortion women.
