Results from bivariable and multivariable logistic regression models values statistically significant at p < 0.05 bolded.
Model adjusts for age, partnership, education, wealth, region, contraceptive use, and method source. Parity excluded due to collinearity with age. Residence excluded due to collinearity with wealth.
Region includes Afar, Benishangul Gumuz, Dire Dawa, Gambella, Harari; combined due to small samples. SNNP-R = Southern Nations, Nationalities, and Peoples' Region.
Public higher-level facility includes government-operated hospitals, health centers, pharmacies, and other government-operated health facilities, except for health posts.
HEW = health extension worker.
