All the data were entered in the Statistical Package of the Social Sciences version 20.0 and analyzed. Point estimate at 90% Confidence Interval was calculated along with frequency and percentage for binary data. RESULTS: Among a total of 47 cases, the vitamin-D deficiency was seen in 21 (44.6%) (32.67-56.52 at 90% Confidence Interval). CONCLUSIONS: The prevalence of vitamin-D deficiency was similar to other studies done in similar settings.
