Abstract

Background: Unintended pregnancy is a global public health issue with significant adverse effects which include health and economic consequences. Globally, there were 121 million unintended pregnancies annually between 2015 and 2019 among women of reproductive age between 15 and 49 mainly due to the non-uptake of modern contraceptives, harmful norms, stigma and lack of sexual and reproductive health care and information.

Methods: We extracted information from the Nigeria Demographic Health Survey conducted in 2008, 2013, and 2018 to assess the trends and factors associated with unintended pregnancies among women of reproductive-aged 15-49. The descriptive summaries were presented using percentages and binomial logistic regressions for the inferential analysis. All analyses were computed using Stata 15.0 at a 5% level of significance and accounted for the complex survey nature as well as the population size.

Results: The study included a total of 63,040 women of reproductive age. The prevalence of unintended pregnancy was highest among adolescents aged 15-19 years (15.1%, 95% CI: 13.9-16.5) and decreased with increasing age. The pooled adjusted model revealed that women had 11% lower odds of reporting unintended pregnancies in 2013 compared to 2008. Adolescent girls (aOR 2.48; 95%CI: 2.14-2.89) and young adults (aOR 1.86; 95%CI: 1.69-2.04) have higher odds of reporting unintended pregnancies compared to older women. Also, unmarried women had 9.8 times higher odds of reporting unintended pregnancies compared to ever-married women.

Conclusions: The findings from this study highlight the need for further family planning educational programs and initiatives that support the uptake of effective contraceptive methods to reduce the likelihood of unintended pregnancy and improve women's sexual and reproductive health while considering regional variations within the country to ensure tailored interventions that address specific needs within each region.
