Abstract:The global population is expected to reach between 7.5 and 10.5 billion by the year 2050. Ethiopia is the second most populous country in Sub-Saharan Africa next to Nigeria. Total Fertility Rate of Ethiopia is 4.1 children per women; contraceptive prevalence rate is 29% for all child bearing age women. The prevalence of long acting reversible contraceptive methods (LARCs) in Ethiopia was very low (4.2%). The cause for low prevalence of LARCs is not known. Thisstudy assessed the acceptance and factors associated with acceptance of long acting reversible contraceptive methods (LARCs) among reproductive age women in Adama Town, Oromia regional state, Ethiopia, 2016. Institution-based cross-sectional study was employed. A total of 644 women attending family planning clinics in health facilities in Adamatownin March 2016 were randomly selected. Structured, pretested and interviewer administered questionnaire was used to collect data. Univariateand Multivariable logistic regression analysis was employed to identify factors associated with acceptance of LARCs methods. Adjusted Odds ratios (AOR) with 95% confidence interval (CI) were used to assess the association among study variables. The acceptance of LARCs methods was found 27.9% Respondents` age (25-34 years) (AOR, 0.19; 95% CI: 0.07, 0.54) were negatively associated, occupation (govern employed) (AOR, 8.80; 95% CI: 1.38, 56.13), Supportive partners attitude (AOR, 30.26; 95% CI: 10.52, 87.03), time taken to arrive the health facility (AOR, 5.68; 95% CI: 2.11, 15.27), partners discussion (AOR, 23.23; 95% CI: 8.55, 63.08) and ever using LARCs before (AOR, 5.50; 95% CI: 2.11, 14.31) were found to have significant and positive association with acceptance of LARCs. CurrentLARCs acceptance is low (27.9%). Regional Health Bureau, Adama Town Health Office and other stakeholders should continue promotion of LARCs. Health professionals should teach both the clients and their partners about the benefits and disadvantage of LARCs. Partners should discus on benefits of using LARCs.
