Determinants of Emergency Contraceptive Use among Adolescent Girls aged 15-19 Years in West Asembo Ward, Rarieda Sub County, Siaya County, Kenya: A Mixed method, Cross-sectional Study.

In West Asembo Ward, Siaya County, 34.8% of adolescent girls aged 15–19 years reported ever using emergency contraception.

• Why it matters: Even with high uptake of conventional contraceptive services, adolescent pregnancies remain high in this ward, leaving uncertainty about EC use and what drives it.
• What they did: A mixed-methods cross-sectional study surveyed 400 randomly sampled girls (15–19) with interviewer-administered electronic questionnaires and analyzed results in SPSS v.29, alongside 10 key informant interviews and 4 focus group discussions.
• The result: EC use was linked to age (18–19 vs 15–17: COR 0.32, 95% CI 0.21–0.50, p < 0.0001), education (lower primary vs no formal: COR 0.04, 95% CI 0.003–0.49, p = 0.012), and living situation among single girls (living alone vs with parents/guardians: COR 5.23, 95% CI 2.86–9.56, p < 0.0001).
