Among women without celiac disease, dietary gluten intake during adulthood was not associated with risk of microscopic colitis, a recent study found. Researchers conducted a prospective study of 160,744 US women without celiac disease enrolled in the Nurses’ Health Study (NHS) and the NHSII. Dietary gluten intake was estimated using validated food frequency questionnaires every 4 years. Among the findings:
- 219 incident cases of microscopic colitis were documented over >20 years of follow-up encompassing 3,716,718 person-years (crude incidence rate: 5.9/100,000 person-years) in NHS and NHSII.
- Dietary gluten intake was not associated with risk of microscopic colitis.
- The adjusted HR of microscopic colitis was 1.18 for the middle quintile and 1.03 for the highest quintile when compared to individuals in the lowest quintile of energy-adjusted gluten intake.
- Additional adjustment for primary dietary sources did not materially alter the effect estimates.
