Unmet need for modern contraception and associated factors among reproductive age group women in Eritrean refugee camps, Tigray, north Ethiopia: a cross-sectional study.

400 women of reproductive age group interviewed. Prevalence of unmet need for modern contraception in this study was found to be 41.8% (95% CI 36.99%, 46.63%).Respondents' unfavorable attitude towards modern contraceptive methods [AOR = 0.372, 95% CI 0.170, 0.818] and the availability of modern contraceptive methods [AOR = 3.501, 95% CI 1.328, 9.231] were factors significantly associated with unmet need for modern contraception. Respondents' attitude towards modern contraceptive methods and availability of modern contraceptives were independent predictors of unmet need. Governmental and non-governmental organizations should design programs to create behavioral change in women's attitude towards contraceptive use and to secure the availability of contraceptive methods in refugee camp settings.
