patients with normal serum 25-OHD

Demographic characteristics of the patients with normal serum 25-OHD and those with serum 25-OHD deficiency are given in Table 1. Of the 242 consecutive patients assessed at baseline, 19 (8%) were found to have a serum 25-OHD of less than 25 nmol/L. Of those patients with 25-OHD deficiency, 11 (57.9%) were osteopenic, one (5.3%) was osteoporotic and seven (36.8%) had normal BMD. These BMD results did not differ significantly from the prevalence of low BMD in the non-25-OHD deficient Crohn’s disease cohort (48.6% osteopenia and 14.2% osteoporosis, P>0.05). In the 25-OHD deficient patients, decreased bone mineral density was most pronounced at the femoral neck and lumbar spine (47.4% and 42.1%, respectively).

This distribution of decreased bone mineral density did not differ from that of patients with normal levels of 25-OHD (51.9% femoral neck and 46.1% lumbar spine, P>0.05). Age at baseline, disease duration, BMI, corticosteroid use, and disease location did not differ between the deficient and normal 25-OHD group. There were a greater percentage of smokers in the 25-OHD deficient group than in the normal group (62.5% and 35.6%, respectively); however, this difference did not show statistical significance (%2=5.929, P=0.115).
