Abstract

Background: Neural tube defects are a significant cause of morbidity and mortality that can occur in the early pregnancy periods. Though the burden is high, it gains only limited attention. In Ethiopia, the estimated number of neural tube defect cases was significantly higher. So, identifying factors contributing to it would be significant for planning risk reduction and preventive strategies. Therefore, identifying the possible determinants was aimed at this study.

Methods: A hospital-based, unmatched case-control study was conducted on 104 cases and 208 controls selected from neonatal intensive care units of teaching hospitals in Gedeo Zone and Sidama Region, southern Ethiopia from December 2021 to November 2022. All neural tube defect cases were included consecutively and controls were selected by using a simple random sampling method. Data were collected using interviewer-administered semistructured questionnaires. Data analysis was done by using SPSS V.25. Binary logistic regression was used, and variables with a p value less than 0.25 in bivariate analysis were entered into the multivariable logistic regression model. An adjusted OR with a 95% CI was estimated, and finally, variables that show a level of p value less than 0.05 in multivariable analysis were declared statistically significant.

Result: After controlling confounders, factors such as unplanned pregnancy 2.20 (95% CI 1.20 to 4.041), history of abortions 2.09 (95% CI 1.19 to 3.67), khat chewing 6.67 (95% CI 2.95 to 15.06), antipyretic and analgesic medications 2.87 (95% CI 1.47 to 5.56) and, being a female neonate 2.11 (95% CI 1.21 to 3.67) were significantly associated with a neural tube defect.

Conclusion: This study has identified some determinants of neural tube defects. Hence, the behavioural, medical and obstetrical conditions of mothers need serious evaluation in the prepregnancy period. So, improving preconception counselling and prenatal care practices would have a significant role in reducing the risk of neural tube defects.
