Zero-inflated negative binomial modelling of antenatal care utilization and it’s predictors in Somaliland: evidence from the 2020 demographic and health survey

Abstract

This study demonstrates that antenatal care utilization in Somaliland remains suboptimal and reveals substantial disparities driven by regional location, nomadic lifestyle, socioeconomic status, education, parity, and access to health information. By applying a zero-inflated negative binomial model, the analysis distinguishes true structural non-users from under-users, offering deeper insight than previous approaches.
