Replicating the Nexus: Sustainable Development and Maternal Healthcare in Ghana,

Title: Replicating the Nexus: Sustainable Development and Maternal Healthcare in Ghana A seminal study proposed a significant positive relationship between national sustainable development indicators and maternal healthcare utilisation in Ghana. This relationship is frequently referenced in policy, but its robustness lacked independent verification. This study aimed to conduct a pure replication to verify the statistical methods, data integrity, and core findings of the original analysis linking sustainable development to maternal healthcare uptake in Ghana. A pure replication methodology was employed. The original dataset was reconstructed using publicly available national survey and World Bank data. All described statistical analyses, including multivariate regression models, were repeated precisely to assess reproducibility. The replication successfully reproduced the study's core regression outputs. A principal finding was corroborated: a one-unit increase in the composite development index was associated with an approximate 7% increase in the odds of skilled birth attendance. Minor discrepancies in variable coding were identified which, while not altering the direction of results, affected the magnitude of some coefficients. The original study's central thesis is supported, confirming a measurable association between broader sustainable development progress and improved maternal healthcare utilisation in Ghana. Future research should employ longitudinal designs to better establish causality. Policy frameworks should continue to integrate health sector planning with broader sustainable development goals, explicitly recognising healthcare access as a development outcome.
