Abstract
The relationship between the congenital defect of gastroschisis and environmental toxins is poorly understood. We examined gastroschisis incidence, risk factors, and spatial association in a geographic region with known environmental pollution and hazardous waste sites. An observational study of fetal and neonatal gastroschisis diagnosed from 1/1/2006 to 12/31/2020 was conducted in a southern West Virginia (WV) tertiary care hospital. Emerging hot spot analysis and Ripley’s K-Function examined the spatial relationship between gastroschisis cases and Environmental Protection Agency (EPA) Federal Registry Sites (FRS). A total of 63 gastroschisis cases provided a prevalence rate of 14.6 per 10000 live births. Gastroschisis was associated with younger maternal age, decreased pre-pregnancy BMI, and increased maternal tobacco use. Relative to FRS sites, spatial clusters were identified with emerging hot spot analysis. Observed Ripley K was higher at all measured bands. Results suggest a potential geographic association between gastroschisis cases and EPA-designated hazardous waste sites.
