Abstract
Background: Study findings on inter-pregnancy interval and its effect on birth outcome are contradictory. Some studies report that it is a risk factor for adverse perinatal outcome while others say it has no association. Still less attention has been given to the way in which changes in family planning related behavior may affect adverse birth outcome.
Identifying the interpregnancy interval at which risk of adverse birth outcome is occurred may benefit developing countries to prioritize family planning services.
Objective: To asses effect of short interpregnancy interval on adverse birth outcome in Gondar and Bahir Dar teaching- referral hospitals, Ethiopia.
Methods: Unmatched case control study design was used in a sample of 548 mothers who gave birth two or more times in Gondar and Bahir Dar teaching-referral hospital, Ethiopia.
Cases were mothers who gave birth to LBW or preterm or stillbirth and controls were mothers who gave normal birth weight or term or live birth. Data were processed and analyzed using EPI Info and SPSS statistical software. A logistic regression was performed to identify the independent effect of interpregnancy interval on adverse birth out come.
Result: The median of interpregnancy interval for cases and controls were 32 and 38 months, respectively.The odd of adverse birth outcome was 2.36 (95% CI = 1.36, 4.08) for women having interpregnancy interval less than 24 months compared with the interval 24 and above.
The odd of low birth weight was 2.67 (95% CI = 1.36, 5.01) when interpregnancy interval was less than 24 months compared to the interval 24 and above months. The odd of preterm birth was 2.92 (95% CI = 1.39, 6.12) for women having interpregnancy interval less than 24 months.
Multivariate analysis showed that women who had interpregnancy interval less than 24 months were about 2.5 times more likely in resulting stillbirth compared to the interval 24 and above.
Conclusion: Interpregnancy interval less than 24 months had a significant effect on adverse birth outcome. So birth spacing education, counseling, and services should be given to women not to be pregnant before 24 months; as adverse birth outcome reduction strategies.
