Impact of vitamin D on the hospitalization rate of Crohn's disease patients seen at a tertiary care center.

ABSTRACT:

Aim

To study the association between vitamin D level and hospitalization rate in Crohn's disease (CD) patients.

Methods

We designed a retrospective cohort study using adult patients (> 19 years) with CD followed for at least one year at our inflammatory bowel disease center. Vitamin D levels were divided into: low mean vitamin D level (< 30 ng/mL) vs appropriate mean vitamin D level (30-100 ng/mL). Generalized Poisson Regression Models (GPR) for Rate Data were used to estimate partially adjusted and fully adjusted incidence rate ratios (IRR) of hospitalization among CD patients. We also examined IRRs for vitamin D level as a continuous variable.

Results

Of the 880 CD patients, 196 patients with vitamin D level during the observation period were included. Partia
