Risk factors for short birth interval: A hospital-based cross-sectional study among women in the Nkongsamba Health District, Littoral Region, Cameroon

Abstract

Short birth interval remains a major reproductive health problem, especially in the developing world. It is associated with maternal, neonatal, infant and under-five morbidity and mortality. This study identifies the risk factors of short birth interval among women in Cameroon. Women in early postpartum (with at least one previous live birth) from four health facilities in the Nkongsamba Health District were consecutively included in the study from September 2021 to December 2021. All data were collected by interview, using a semi-structured questionnaire, and analysed in Epi-Info version 7.2.3.1. With a statistically significant threshold of 5%, the adjusted odds ratio was used in multiple logistic regression to measure the association between short birth interval and potential factors. This study included a total of 679 participants with an age range of 18 to 47 years. Short birth interval was recorded in 46.10 [95%CI: 42.38-49.86]% of these women. A little more than half (56.72%) had at most 4 pregnancies already, while only 06.35% had at least 8 pregnancies in their reproductive life. Maternal age ≤ years (AOR = 2.66[1.80-3.93]), less than or equal to 10 months of breastfeeding of the previous child (OR = 2.48[1.80-3.41]), use of modern contraception before conception (AOR = 0.62 [0.43-0.89]), and the number of household occupants below 5 (AOR = 0.60[0.40-0.92]) were significantly associated with short birth interval. Short birth interval remains a significant call for concern in Cameroonian women. The likelihood of short birth interval is affected by maternal age, duration of breastfeeding, use of modern contraception and number of household occupants. Interventions to promote effective breastfeeding and postpartum family planning uptake are indispensable in the fight against short birth interval in Cameroon.
