Spatial Heterogeneity and association between the survey-based Women's Empowerment Index (SWPER) and unmet need for birth spacing in sub-Saharan Africa.

Background: Unmet need for birth spacing can significantly impact maternal and child health outcomes, leading to unintended or mistimed births, neonatal mortality, pregnancy loss, induced abortions, small-sized births, and malnutrition. Considering the role of women empowerment in women's sexual and reproductive health, we examined the association between the survey-based women's empowerment index (SWPER) and unmet need for spacing in sub-Saharan Africa (SSA).

Methods: We used data from the Demographic and Health Surveys of 21 in SSA conducted between 2015 and 2021. In this study, the unit of analysis was women of reproductive age (15 to 49 years) who were married or living together and required family planning during the survey period. Multilevel logistic regression was fitted to examine the association between SWPER and the unmet need for spacing. The results were presented using adjusted odds ratios (AORs) with 95% confidence intervals (CIs).

Results: The hotspot countries for unmet need for birth spacing were Angola, Benin, Liberia, Mauritania, and Sierra Leone. The findings showed that with the empowerment indicators, women with high attitude to violence (disagreement or rejection of violence) (AOR = 0.95; 95% CI 0.91, 0.99), and women with high decision-making (AOR = 0.90; 95% CI 0.85, 0.95) exhibited lower odds of unmet spacing need relative to women with low attitude to violence and those with low decision making. Women with high autonomy (AOR = 1.32; 95% CI 1.25, 1.39) were more likely to experience unmet need for spacing compared to those with low autonomy.

Conclusion: Unmet need for spacing has been linked to indices of women's empowerment such as attitudes toward violence, independence, and decision-making. Organizations such as UNICEF, UNFPA, and the Bill & Melinda Gates Foundation should consider incorporating SWPER indicators when planning interventions to address the high unmet need for spacing among women in SSA. Additionally, various governments and aid organizations must give women's empowerment a high priority as a tactical intervention strategy to increase access to contraception in the countries considered in this study. These programmes would contribute to attaining SDGs 3.1 and 3.7.
