The pregnancy may end with early childbirth, induced abortion and its complications. Although, the trends of unintended pregnancy and induced abortion have declined over time in Ethiopia, evidence is limited on key determinants for decline in order to propose vital areas of interventions. The current study aimed to identify the determinants of unintended pregnancy and induced abortion among adolescents over the decades.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"sec002\">\n<jats:title>Methods<\/jats:title>\n<jats:p>Trends in the prevalence of unintended pregnancy and induced abortion among adolescent women aged 15\u201319 years were investigated based using a series of the Ethiopia Demographic and Health Surveys (EDHS) data for the years 2000, 2005, 2011, and 2016. Sub-sample of adolescent women data was extracted from each survey. The combined datasets for unintended pregnancy and induced abortion over the study period (2000\u20132016) was analyzed. The percentage changes of trends of unintended pregnancy and induced abortion with its corresponding 95% CI for each variable were calculated. Multilevel mixed-effects decomposition analysis was applied to identify factors significantly associated with trends of unintended pregnancy and induced abortion among adolescents.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"sec003\">\n<jats:title>Results<\/jats:title>\n<jats:p>The trends of unintended pregnancy and induced abortion significantly declined during the study period. Unintended pregnancy among Ethiopian adolescents aged 15\u201319 years significantly decreased from 307 (41.4%) (95% CI: 35.7, 47.2%, p&lt;0.001) in 2000 to 120 (25.1%) (95% CI: 18.9, 31.4%) in 2016. On the other hand, induced abortion significantly decreased from 62 (8.3%) (95% CI: 5.2, 11.4%) in 2000 to 20 (4.1%) (95% CI: 1.3, 6.9%, p = 0.004) in 2016. Age older than 18 years (Coeff = -0.41, 95%CI, -0.64, -0.18, p&lt;0.001), living in Somali regional state (Coeff = -2.21, 95%CI, -3.27, -1.15, p&lt;0.001) and exposure to media (Coeff = -0.60, 95%CI, -0.87, -0.33, p&lt;0.001) showed a significance association with decline in unintended pregnancy whereas; living in Benshangul-Gumuz regional state (Coeff = -0.17, 95%CI, -0.32, -0.19, p = 0.03) and ANC service utilization history (Coeff = -0.81, 95%CI, -1.45, -0.17, p = 0.01) showed significance association with decline in induced abortion.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"sec004\">\n<jats:title>Conclusion<\/jats:title>\n<jats:p>The trends of unintended pregnancy and induced abortion significantly declined over the past decades in Ethiopia. Adolescent girls aged 17 years and above, exposure to media and living in Somali showed significant association with decline in unintended pregnancy whereas; living in Benshangul-Gumuz and ANC service utilization history showed significant decline with induced abortion. Exposure to media and utilization of Antenatal care (ANC) services may improve adolescent girls\u2019 reproductive health uptake.<\/jats:p>\n<\/jats:sec>","DOI":"10.1371\/journal.pone.0299245","type":"journal-article","created":{"date-parts":[[2024,3,15]],"date-time":"2024-03-15T17:45:57Z","timestamp":1710524757000},"page":"e0299245","update-policy":"https:\/\/doi.org\/10.1371\/journal.pone.corrections_policy","source":"Crossref","is-referenced-by-count":1,"title":["Determinants of unintended pregnancy and induced abortion among adolescent women in Ethiopia: Evidence from multilevel mixed-effects decomposition analysis of 2000\u20132016 Ethiopian demographic and health survey data"],"prefix":"10.1371","volume":"19","author":[{"given":"Tiruwork","family":"Amare","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fasil","family":"Tessema","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1896-1208","authenticated-orcid":true,"given":"Tamrat","family":"Shaweno","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"340","published-online":{"date-parts":[[2024,3,15]]},"reference":[{"journal-title":"Unintended Pregmancy","author":"CDC (Reproductive Health).","key":"pone.0299245.ref001"},{"issue":"4","key":"pone.0299245.ref002","doi-asserted-by":"crossref","first-page":"e0231012","DOI":"10.1371\/journal.pone.0231012","article-title":"Prevalence and determinants of unintended pregnancy in Ethiopia: A systematic review and meta-analysis of observational studies","volume":"15","author":"M Alene","year":"2020","journal-title":"PLoS ONE"},{"key":"pone.0299245.ref003","doi-asserted-by":"crossref","first-page":"e07869","DOI":"10.1016\/j.heliyon.2021.e07869","article-title":"Prevalence and determinants of unintended pregnancy in Ethiopia: Narrative synthesis and meta analysis.","volume":"7","author":"K Kebede","year":"2021","journal-title":"Heliyon"},{"issue":"2","key":"pone.0299245.ref004","first-page":"187","article-title":"Prevalence and Determinants of Unintended Pregnancy in Sub\u2013Saharan Africa: A Systematic Review.","volume":"24","author":"LE Bain","year":"2020","journal-title":"Africa Journal Reproductive Health"},{"journal-title":"Abortion","author":"WHO","key":"pone.0299245.ref005"},{"key":"pone.0299245.ref006","doi-asserted-by":"crossref","first-page":"415","DOI":"10.1186\/s12905-022-01962-0","article-title":"A systematic review on abortion decision making in legally restricted settings in sub-Saharan Africa, Latin America, and the Caribbean.","volume":"22","author":"L.
