Adequacy of prenatal care and its association with pregnancy outcomes: A comparison of indices in Tabriz, Iran

Introduction: Improving of mother and child health is one of the most important and essential roles of public health agencies and millennium development goals. The aim of this study was to determine rates of prenatal care (PNC) utilization in Tabriz, Iran, from 1994-2013 and compare the two most commonly used models of PNC utilized in determining the proportion of the pregnant woman receiving inadequate PNC and comparing use of two indices. Methods: In this study, we conducted a descriptive cross-sectional study of 2834 women having a health record in care center of the rural region in Tabriz for 20 years. We used questioner that validated in the study Jabbari et al. for obtaining data. Random sampling quotes were done in 3 times during the years 1994-2013. Results: We found that 53% of mothers received adequate care by adequate PNC utilization (APNCU) index, but 17% by revised-GINDEX index but the most important objective of our study was identifying the relationship between adequacy of PNC and pregnancy outcome. On the other hand, the study indicated that between inadequate care and low birth weight (LBW), mother weight gaining, birth height exists significant association, but there is no meaningful correlation between birth weight and adequacy of care (P < 0.05). Conclusion: The study analyzed the effect of PNC utilization on birth outcomes and suggested that PNC decrease LBW through both increasing gestational age as well as improving fetal growth at the same time it improves birth height and mother weight gaining. All findings of this study emphasize the need for health policies to improve utilization and access PNC.
