Independent and joint contributions of inadequate antenatal care timing, contacts and content to adverse pregnancy outcomes

BACKGROUND: Poor quality and inadequate of antenatal care (ANC) visits during pregnancy may increase the risk of preventable adverse pregnancy outcomes. We tested the hypothesis that the adequacy of ANC utilization combined with quality of ANC services will reduce the risk of low birth weight (LBW) and preterm delivery (P T D) in the Tamale metropolis of Ghana. MATERIALS AND METHODS: A facility-based analytical cross-sectional study was conducted on a sample of 553 postpartum women who had delivered within the last 12 months prior to the study. The overall utilization of ANC services was measured in terms of ANC timing, contacts, and content (TCC) of essential ANC services. The sample was drawn using systematic random sampling procedure. Primary data was collected from mothers by administering a structuredquestionnaire while the secondary data was extracted from individual records. RESULTS: After controlling for confounders, women who had adhered to all WHO recommendations in terms of ANC timing, frequency and content were 71 % protected from PTD, AOR = 0.29 (95 % CI: 0.15, 0.59) and 56 % protection from LBW AOR = 0.44 (95 % CI: 0.23, 0.83). CONCLUSION: Individually and jointly, inadequate ANC contacts and content associatedsignificantly with preterm delivery than LBW. KEY MESSAGES: Limited evidence exists on the joint effect of ANC services timing, contacts and content on adverse pregnancy outcomes. Total adherence to recommended ANC initiation, attendance and receipt of essential services had greater protection against PTD and LBW, compared to any single element/component of ANC. Women who had adequate overall ANC services utilization in terms of timing, contacts and content were 71 % protected from PTD, AOR = 0.29 (95 % CI: 0.15, 0.59) and 56 % protection from LBW AOR = 0.44 (95 % CI: 0.23, 0.83).
