Celiac Disease: Unequal Impact Across Races

A study from Penn State College of Medicine highlights racial differences in how celiac disease impacts patients. Using data from over 95 million U.S. healthcare records, the researchers compared minority patients with celiac disease to non-Hispanic white patients between 2016–2021. In this study, the "minority" group was defined as Hispanic/Latino, Black, African American, Asian, American Indian, Alaska Native, and Native Hawaiian patients. 

The findings show that while both groups had similar rates of iron, vitamin B, and zinc deficiencies, minority patients experienced significantly higher rates of vitamin D deficiency and anemia linked to iron deficiency than non-Hispanic white patients did. Minority patients also had greater healthcare utilization, with more frequent emergency visits and inpatient hospital stays.

Nutrient deficiencies are common in newly diagnosed celiac patients due to intestinal damage that impairs absorption of key nutrients like vitamin D, calcium, iron, B12, folate, and zinc. Although a gluten-free diet often improves these deficiencies, persistent symptoms such as diarrhea and vomiting can worsen nutritional status.

Overall, the study underscores that while people with celiac disease are at heightened risk of nutrient deficiencies, minority patients may face additional challenges. Further research is needed to understand why these disparities exist.
