Background: There is no structured content and modalities for the delivery of antenatal education in Nigerian healthcare institutions. Hence, the lack of knowledge on salient issues that are pivotal to survival of mothers and their babies among childbearing women. This study assessed the contents and mode of delivery of antenatal education from the perspective of care providers. Methods: A descriptive cross-sectional study design was adopted using structured questionnaire developed by the researchers for data collection. One hundred and ten nurses were recruited across various healthcare institutions in Oyo state, Nigeria to participate in the study. Results: The mean age of the nurses is 39.7 with standard deviation of 10.1. About half (43.6%) of them have first degree in Nursing, while one-third (31.8%) are at the lower cadre of Nursing (Nursing officer II). The most common five topics taught by the nurses as reported are; hygiene (98.2%), diet (84.6%), immunization (31.8%), birth preparedness (31.8%), and breastfeeding (28.2%). The most common mode of delivery is face-to-face teaching (98.2%) while e-teaching is least employed (20.9%). Pictures (87.3%) and posters (79.1%) are the most common materials used for teaching while majority (72.7%) provide fliers as teaching materials to their clients. Majority (98.2%) of the nurses’ state that they provide antenatal education to serve as learning forum for their clients, however, very few (17.3%) stated that they provide antenatal education to keep their clients busy while waiting for doctor’s consultation. Conclusion: There is no structured content for antenatal education being offered to pregnant women during antenatal clinic. However, every pregnant woman attending antenatal clinic will benefit from balanced information that will enhance positive pregnancy outcome from her care provider. Hence the need for structured content and modalities of delivery of antenatal education in Nigeria.
