Insights
Congenital anomalies in Bangladesh occurred at a rate of 0.8%, with central nervous system defects being most common. Maternal age over 30, consanguinity, family history, no folic acid intake, and passive smoking were identified as significant risk factors.
Area of Science:
- Obstetrics and Gynecology
- Neonatal Health
- Public Health
Background:
- Congenital anomalies are a major cause of neonatal mortality in Bangladesh.
- Identifying country-specific risk factors is crucial for understanding the burden of these anomalies.
- Previous research has not fully elucidated the patterns and maternal risk factors in the Bangladeshi context.
Purpose of the Study:
- To determine the patterns and prevalence of fetal congenital anomalies in Bangladesh.
- To identify maternal risk factors associated with congenital anomalies in newborns.
- To provide data for targeted public health interventions.
Main Methods:
- A cross-sectional comparative study was conducted at Mymensingh Medical College Hospital, Bangladesh.
- Data on 11,479 deliveries were collected from September 2019 to August 2020.
- Statistical analyses included Chi-square tests, bivariate analysis, and multivariate logistic regression.
Main Results:
- The overall frequency of congenital anomalies was 0.8% (87 cases out of 11,479 deliveries).
- Central nervous system anomalies were the most prevalent, accounting for 49.4% of cases.
- Independent risk factors identified include maternal age >30 years, consanguinity, family history of anomalies, no folic acid intake, and passive smoking.
Conclusions:
- Congenital anomalies represent a significant public health concern in Bangladesh, with a notable prevalence of central nervous system defects.
- Maternal age, consanguinity, family history, folic acid supplementation, and exposure to passive smoking are key modifiable and non-modifiable risk factors.
- These findings underscore the need for improved maternal health education and targeted interventions to reduce the incidence of congenital anomalies.
Abstract:
Congenital anomalies are one of the four leading causes of neonatal mortality in Bangladesh. The risk factors which are predictive of congenital anomaly in babies vary from country to country. In a developing country like Bangladesh many possible factors are present which should be identified & frequency needs to be assessed to understand the burden. The aim of this study was to determine the patterns and related maternal factors of fetal congenital anomaly. This cross-sectional type of comparative study was conducted at Department of Obstetrics & Gynecology in Mymensingh Medical College Hospital, Mymensingh, Bangladesh from September 2019 to August 2020. All the births occurring in the labor room were recorded. All newborn babies born with congenital anomalies were identified & included in this study. The rate of congenital anomalies was estimated and common types of congenital anomalies were noted. This study was conducted involving all women who had babies with congenital anomalies and the same number whose babies had no congenital anomalies. A structured questionnaire was used during data collection. Data was analyzed by Chi square test, bivariate analysis & multivariate logistic regression using statistical package for social sciences (SPSS) version 26.0. During the study period, 11479 deliveries were conducted. Among them 87 cases with congenital anomalies were identified. Frequency of congenital anomaly was 0.8%. Central nervous system was the predominant system involved (49.4%). Regarding risk assessment, Maternal age >30 years (OR 2.96, 95% CI 1.10-7.93, p value 0.032), consanguinity (OR 7.73, 95% CI 1.79-33.39, p value 0.006), first degree relative with history of congenital anomaly (OR 35.52, 95% CI 4.31-292.86, p value 0.001) and no intake of folic acid (OR 15.99, 95% CI 5.28-48.52, p value <0.001), passive smoking (OR 6.45, 95% CI 1.66-25.09, p value 0.007) were independent risk factors for congenital anomalies.
