Adults With Undiagnosed Celiac Disease May Have Lower Bone Mineral Density
Celiac disease is an autoimmune disease in which people can't eat gluten because it will damage their small intestine. A new study has found that adults with undiagnosed celiac disease may have lower bone mineral density than adults without celiac disease.
Researchers from the George Mason University College of Health and Human Services looked at data from the What We Eat in America and the National Health and Nutrition Examination Survey 2009–2014. The survey included 13,000 adults who were not pregnant or eating a gluten-free diet. Participants self-reported dietary and supplement intake, and bone density in the thighbones and femur necks was measured.
Participants with undiagnosed celiac disease were found to have lower femur bone mineral density and lower femoral neck bone mineral density compared to those without celiac disease. No differences were found in total spine bone mineral density. Participants with undiagnosed celiac disease were also found to have higher daily calcium intake and higher dairy consumption. The fact that they had lower bone mineral density suggests their bodies are not correctly absorbing nutrients.
The study was published online ahead of print on July 19, 2019 in the Journal of the American College of Nutrition.
