Prevalence and factors associated with preterm birth in a rural district hospital, Rwanda

INTRODUCTION: globally, the leading cause of neonatal mortality is preterm birth which may hinder the achievement of Sustainable Development Goal 3.2 target. We aimed to determine the prevalence and factors associated with preterm delivery at Kabutare hospital, Rwanda. METHODS: a cross-sectional study was conducted between August and September 2020. Mothers were interviewed using a standard pretested semi-structured questionnaire and additional data were extracted from medical records of obstetric files. Gestational age was assessed using the Ballard score. Adjusted Odds Ratios and their 95% confidence intervals were calculated for multivariable logistic regression analysis to take care of all potential confounders. RESULTS: the prevalence of preterm birth was 17.5% (95% CI: 12.9% - 22.9%). The independent factors associated with preterm birth after considering multiple logistic regression were husband being a smoker (adjusted Odds Ratio (aOR) = 5.9; 95% CI; 1.9-18; p= 0.002), antenatal care (ANC) attendance ≤ 3 visits (aOR=3.9; 95% CI; 1.1-13.8; p=0.04) and low mother's Mid Upper Arm Circumference (MUAC) < 23cm (aOR=5.6, 95% CI; 1.8-18.9; p=0.004). Conclusion: preterm delivery was high in Huye district. Thus, we recommend ANC sessions to emphasize on maternal nutritional education which is of good quality and quantity, discourage maternal alcohol consumption as well as passive smoking.
