Background and purpose: Vitamin  deficiency has been observed in both developed and developing countries, including the Middle Ëast. Ïn this study, the prevalence of vitamin D deficiency was investigated in Ïsfahani male and female high school students in 2004.
Materials and methods : Ïn a cross-sectional study, 318 students (153 boys & 165 girls) aged 14-18 years were selected by multistage random sampling. Data were collected by interview and serum 25-hydroxy vitamin D was measured. Vitamin D deficiency was defined as serum 25-hydroxy vitamin D<20 ng/ml.
Results : The prevalence of vitamin D deficiency in all subjects was 46.2% (72.1% in females and 18.3% in males). Vitamin D deficiency was about 4 times more prevalent in female students than males (ÔR=3.9 , 95% ÇÏ=1.88-3.91 . P<0.001). The sun exposure in males and females was 2.29 ± 1.52 and 1.12 ± 0.84 hour/day, respectively (P<0.001).
Çonclusion: Vitamin D deficiency is common in high school students, especially in girls. Âvoidance of sunshine is probably the main factor contributing to vitamin D deficiency of Ïsfahani students.
