Factors Associated with Short Births Intervals among Women Delivering at Mbarara Hospital

Abstract

Background; Birth interval is the time between two consecutive births. World Health Organization recommends a minimum birth to pregnancy interval of 24months after live birth and 6months after abortion. Short birth interval is associated with adverse perinatal and maternal outcomes. Few studies have described factors associated with birth intervals. Knowing these factors will enable stake holders and care providers to modify practice to address them thus improving neonatal infant and maternal health.Methods: This was a case-control study. We enrolled 56cases and 162 controls that consented to the study and interviewed them. Statistical analysis was done using SPSS statistical software, version 20 (SPSS, Chicago, IL, USA). Cross tabulations was conducted to obtain descriptive statistics. Bivariable and multivariable logistic regression models were used to test the association.Results: The age of participants ranged from 17 to 42years, the modal birth interval as 36months. Age below 30years P=0.015 (OR 2.3 CI 1.17-4.67), low education level P= 0.005, lack of contraceptive use P=0.000 and lack of contraceptive P=0.000. A previous good fetal birth outcome and having live child was protective P=0.000, P=0.000 respectively.Conclusion and recommendation: Contraceptive knowledge and use programs targeting mothers below 30years should be strengthened especially in the postnatal period. Universal secondary school education program should be strengthened. Programs to improve neonatal and child survival should be strengthened as they directly affect child spacing thereby indirectly affecting maternal health.
