Background: World over, there has being an improvement in birth spacing resulting in a reduction in the perinatal and maternal morbidity and mortality rates. Objective: To appraise the factors influencing inter-pregnancy interval (IPI) among pregnant women receiving antenatal care at Federal Teaching Hospital Abakaliki. Methods: A descriptive cross-sectional study was done among antenatal attendee, with at least one previous delivery, in Federal Teaching Hospital, Abakaliki over a six month period using a structured questionnaire. Data obtained was analysed using IBM SPSS Statistics version 20. Results: The mean age of the respondents was 28.6 (95% CI 28.1-29.1) years. The majority (231, 70%) were multiparous. Most respondent (162, 49.1%) had their last delivery 6-12 months prior to conception. The significant determinants of IPI include: maternal age, marital status, place of residence, social class, baby's sex, family income, use of contraceptive, parity and outcome of her last confinement. Contraceptive knowledge is high (300, 90.9%); more than 50% had the desire to use some form of contraceptive but majority (132, 40%) said they will never use contraceptive after delivery. Conclusions: Majority of the women had an IPI of 6-12 months. The major determinant of this includes having a live birth in last delivery, parity, marital status, and place of residence. The attitude to contraception is poor; effort needs to be directed into identifying the immediate and remote causes of this as this will help in proper education and counselling needed to increase contraceptive uptake.
