Abstract

Background: Congenital malformations of the digestive system (CMDS) are one of the major causes of newborn mortality, particularly in developing countries. This study was conducted to evaluate the prevalence, pattern, gender distribution of CMDS as well as ethnicity status among newborns in Golestan Province, northern Iran.
Methods: This descriptive and analytical study was conducted on 36,156 live births to identify all newborns with CMDS, born between March 2018 and March 2019 in Golestan Province, north of Iran. The type of CMDS according to the International Classification of Diseases (ICD-10), the gender and ethnicity status of the newborns were recorded. The prevalence rate was estimated and compared using the exact Poisson method and odds ratio with a 95% confidence interval. Data were analyzed using STATA 14.0 software.
Results: The prevalence rate of CMDS in newborns was 2.13 per 1000 live births. The risk of CMDS was significantly higher in males compared to females (OR=1.78, 95% CI: 1.12-2.85). The most common anomaly was Ankyloglossia (19.28%). The prevalence rate of CMDS among native Fars, Turkmen and Sistani ethnic groups was 2.15 [95% CI: 1.50-2.99], 3.05 [95% CI: 2.06-4.35] and 1.48 [95% CI: 0.64-2.91] per 1000 live births, respectively.
Conclusion: Due to the prevalence rate of CMDS and ethnic diversity in this region, effective prevention planning, early diagnosis and thorough screening are particularly important, especially in high-risk groups.
