CBC differential and serum ferritin were measured. Iron deficiency was defined as serum ferritin≤12μg/L and anemia was defined as Hb<12g/dL and iron deficiency anemia was defined as both (SF≤12, Hb<12).The obtained data were analysed by means of SPSS software and statistical tests (Chi-Square and Fisher) at the level of  =0.05. Results: Prevalence of anemia was 3.6%, iron deficiency anemia 1.8% and iron deficiency was 24%. Prevalence of iron deficiency showed significant relationship to sex (female), menstruation, and increasing age. There was not a significant relationship between iron deficiency and its respective anemia to score, degree of birth, body mass index, age, job, and parents’ level of education.
