A systematic random sampling technique was applied to select the study participants.Setting Five public HCs (Han HC, Shimbit HC, Dagmawi Minilik HC, Shumabo HC and Meshentie HC) in Bahir Dar Zuria zone.Participants Pregnant mothers who were attending their ANC service during the data collection period were enrolled in this study. A total of 592 mothers were interviewed for the study.Outcome measure Early initiation of ANC services (within 16 weeks of gestation).Results 48.6% (95% CI 41.6% to 53.5%) of participants began their first ANC service before 16 weeks of gestation. Family size less than five (adjusted OR 2.0, 95% CI 1.25 to 3.25), urban residence (3.0, 1.48 to 6.17), secondary education (2.1, 1.3 to 3.6), college-level education and above (3.5, 1.8 to 6.8), primigravida (2.6, 1.65 to 4.14), planned pregnancy (3.5, 1.5 to 8.1) and knowledge about early initiation of ANC (1.7, 1.14 to 2.55) were significantly associated with early initiation of ANC.Conclusion A substantial number of participants had not received ANC services in a timely manner. Sociodemographic and obstetric characteristics of the respondents were associated with timely booking of ANC services. Dissemination of information about recommended time to initiate ANC services and efforts to improve women’s educational status to increase knowledge about early initiation of ANC are needed in the region.Data are available upon reasonable request.
