The study assessed the factors influencing the utilization of Maternal Healthcare Centers (MHC) for delivery among pregnant women attending ante-natal care in Ikenne, Ogun state, Nigeria. A total of 96 respondents were selected from 5 MHC for the study using the multistage sampling procedure. All the women were monitored till delivery. Furthermore, 48 (50%) of the respondents were randomly chosen and exposed to motivational telephone calls for 6 weeks preceding delivery dates. Structured questionnaire was used to gather data which were analyzed using descriptive statistics and logistic regression. All analyses were measured at p≤0.05 level of significance. Results showed that most of the women were between 30 and 34 years old, had up to secondary education, recorded parity of 1-2 while timing of first visit was between 20 and 24 weeks of gestation and number of Ante-natal visits were ≥ 4. Monthly income was generally less than N16,000 (~$80). Some 52% of the women gave fair rating for the services received from the healthcare workers and 58% used the MHC for delivery. However, 84% of those who received telephone calls used MHC for delivery while 59% of those who did not received telephone calls used MHC for delivery.
