Azerbaijan is the country with one of the highest child mortality rates in the region of Eastern Europe and the former Soviet Union. Drawing on the nationally representative demographic and health survey, this study examines utilization of antenatal care in Azerbaijan to identify the socio-economic determinants of the usage, and its frequency, timing and quality. Consequently, binomial logit, two ordered logit and negative binomial regression models are specified to estimate the effect of various socio-economic characteristics on the likelihood of utilization. Place of living is an important determinant of antenatal health-care utilization in Azerbaijan. It is important in determining the likelihood of utilization, its timing, and quality of care received, whereas it is not significant in the model predicting frequency of antenatal utilization. A women's education is also significant in three models out of four. Education is important in explaining frequency and timing of utilization as well as quality of services received, but it is not significant in predicting the likelihood of utilization. Wealth gradient is another important determinant of antenatal care utilization in Azerbaijan inasmuch as it is significant in explaining the likelihood of prenatal care utilization and its frequency. In addition, two variables, birth order and desirability of the last child or current pregnancy are significant only in explaining likelihood of utilization. Therefore, we confirm findings of previous studies, which reported that utilization of prenatal health care is a multistage process where decisions are sequential. Although the same set of factors may affect decision-making at all stages, the effect of these factors is different at different stages. Implications for reforms in health-care sector to improve antenatal care utilization in Azerbaijan are provided and discussed
