Incidence of Congenital Diaphragmatic Hernia in Canada: Time Trends and Analysis by Location, Maternal Age, and Sex

jpedsurg.org

Congenital diaphragmatic hernia (CDH) is a birth defect of unknown etiology, whose epidemiology has not been extensively studied in Canada. The aim of our study was to report the incidence of CDH in Canada and its provinces/territories by year and putative risk factors.

In brief

This epidemiological study examines the incidence patterns of congenital diaphragmatic hernia across Canadian provinces and territories, analyzing temporal trends and potential risk factors including geographic location, maternal age, and fetal sex. The research addresses a gap in Canadian CDH surveillance data.

CDH etiology remains unknown; Canadian epidemiological data are limited and require systematic analysis.
Study examines CDH incidence trends across Canadian provinces/territories to identify geographic variation.
Analysis stratifies CDH cases by maternal age to assess age-related risk patterns.
Sex-based incidence differences are evaluated to determine if CDH shows gender predilection.
Time-trend analysis may reveal changes in CDH detection or prevalence over study period.
