BACKGROUND: Congenital neurosurgical anomalies, such as neural tube defects (NTDs) and hydrocephalus, are prevalent central nervous system disorders. This study investigates their prevalence and factors statistically associated with their occurrence.
METHODS: A retrospective cross-sectional study at Mbeya Zonal Referral Hospital (MZRH) from May 2023 to April 2024 included 978 patients. Data from 145 children with CNS anomalies were analyzed using Microsoft Excel and STATA-15, with binary logistic regression to identify potential risk factors associated with these conditions.
RESULTS: The prevalence of congenital neurosurgical conditions was 14.3% (145/978). Hydrocephalus occurred in 8.3% (81/978), NTDs in 5.01% (49/978), Chiari malformations in 0.92% (9/978), and encephalocele in 0.61% (6/978). Logistic regression found that folate deficiency associated with delayed antenatal care was linked to a higher likelihood of NTDs and hydrocephalus (OR 2.56, p ≤ 0.005). Other factors showing statistical associations included prematurity, low birth weight, pregnancy infections, unprescribed drug use, malnutrition, gestational diabetes, and hypertension.
CONCLUSION: Key factors statistically associated with congenital CNS anomalies in this cohort include low birth weight, prematurity, inadequate folic acid intake, gestational diabetes, maternal hypertension, and unprescribed drug use. These findings highlight the importance of early prenatal care and maternal health optimization to potentially reduce the occurrence of these anomalies.
