Gastroschisis Prevalence in Canada by Season and Latitude, 2006-2020

Canada-wide data on gastroschisis prevalence among infants conceived between April 2006 and March 2020. The dataset likely contains results from a population-based cohort study examining associations with conception month and geographic latitude. The research was authored by Shiliang Liu and published on figshare.

Use Cases

• Analyze seasonal patterns in gastroschisis prevalence based on conception month.
• Study geographic variation in birth defect risk based on latitude.
• Model the protective effect of sunlight exposure based on rural vs urban residence indicators.
• Investigate potential non-monotonic relationships between maternal vitamin D status and gastroschisis risk.

Strengths

• Dataset is based on a population-based cohort study covering 14 years (2006-2020).
• Results include specific prevalence rates (e.g., 4.6 per 10,000 for winter conceptions) and adjusted rate ratios with confidence intervals.
• Analysis incorporates multiple indicators: conception month, latitude, and rural/urban residence.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is very small (25.9 KB), suggesting it may contain summary statistics rather than raw patient-level data.
