Abstract

Background and objectives Vitamin D deficiency and insufficiency are a commonly reported health problem throughout the world. This cross sectional survey was conducted in Duhok governorate with an aim to assess vitamin D status in a sample of apparently healthy population.Methods Serum 25-hydroxyvitamin D was determined for all enrolled subjects (n=1270), including newborn babies and infants (n=24), primary school children (n=53), adolescents (n=85), adults (n=1086) and elderly (n=22).Results There was a statistically significant difference in mean 25-hydroxyvitamin D levels between different age groups (p= 0.02) and different gender (P= 0.001). Overall 731(57.6%) subjects were with low 25-hydroxyvitamin D < 30ng/ml, of these, 651(51.3%) subjects were vitamin D insufficient (10-29.9 ng/ml), while 80(6.3%) subjects had severe vitamin D deficiency (< 10 ng/ml), with a significant difference among age groups (p= 0.003).
