Introduction: The rapid and unexpected increase in the sex ratio at birth in Nigeria between 1996 and 2014 is yet to be fully explained. The contribution of sex-selective abortion has not been explored.
Methods: A cross-sectional survey of pregnant women was employed to address this need.
Results: Preference for sex-selective abortion was noted in 8.6% of the respondents. The association between parity ≥ 4 and preference for sex-selective abortion was statistically significant. Women who were child gender-biased were significantly more likely to prefer sex-selective abortion. Experiencing intimate partner violence, and having problems with in-laws for inability to give birth to their desired gender, were predictors of maternal preference for sex-selective abortion. Women who preferred sex-selective abortion, however, felt it was necessary to campaign against gender preference.
Conclusion: Preference for sex-selective abortion exists in Nigeria, despite our restrictive abortion laws. However, the women's underlying reasons may include gender balancing in the family and an escape from discrimination. Improving contraceptive uptake, restriction of disclosure of fetal sex for non-medical indications, and sanctions against violent partners/oppressive in-laws are advocated. Rapid progress towards achieving a world free of the offensive gender inequalities that force women to opt for sex-selective abortion ab initio is desirable.
