overall prevalence of osteopenia and osteoporosis was 50.2% and 31.2% respectively. Serum 25(oH)D levels were not significantly different between those subjects with osteopenia (9.42±7.15 ng/ml) and osteoporosis (10.22±8.76 ng/ml, p =0.096). However prevalence of osteopenia progressively increased from 42.3% in those with normal vitamin D levels to 53.2% among those with severe vDD (Fig. 1).
