Effect of maternal age on facility-based delivery: analysis of first-order births in 34 countries of sub-Saharan Africa using demographic and health survey data.

Older age at first birth was independently associated with significantly higher odds of facility-based delivery. This went against the hypothesis. Further mixed-method research is needed to explore how increased age improves uptake of facility-based delivery. Promoting facility-based delivery, while ensuring quality of care, should be prioritised to improve birth outcomes in sub-Saharan Africa.
