Determinants of maternal healthcare service utilisation among Indonesian mothers: A population-based study.

Background: In Indonesia, maternal health care services are widely available, aiming to improve health and survival among mothers. However, these services remain underutilised, and its determining factor was unknown. This study sought to identify determinant factors of maternal healthcare services utilisation among Indonesian mothers. Methods: This population-based cross-sectional study leveraged the 2017 Indonesia Demographic and Health Survey data. A total of 12,033 mothers aged from 15 to 49 years who had a live birth in the five years preceding the survey were included in the analysis. Multivariable logistic regressions were used to identify the determinant factors. Results: Approximately 93.44% of the mothers had adequate antenatal care, 83.73% had a delivery at the healthcare facility, and 71.46% received postnatal care. The mother's age and household wealth index were the typical determinants of all maternal healthcare services. Determinants of antenatal care visits were husband's occupational status, the number of children, and access to the healthcare facility. Next, factors that drive mothers' delivery at the healthcare facility were the mother's education level, husband's educational level, and residential area. The use of postnatal care was determined by the mother's occupational status, husband's educational level, number of children, wealth index, access to the healthcare facility, and residential area. Conclusions: Although there were differences in the determinant factors of three key maternal healthcare services, the mother's age and household wealth index were the typical determinants of all maternal healthcare services utilisation. Providing a tailored programme aligned with these determinant factors may ensure that mothers can access and adequately utilise maternal healthcare services.
