Background: Micronutrients (zinc and iron) deficiency has been alarmed as worldwide public health problem. The adolescents are one of the most vulnerable groups to nutritional deficiency and need more nutritional care for proper growth and development. Data on nutritional status of zinc and iron among early adolescent in the Gaza strip (GS) are absent. Aim: To assess zinc and iron nutritional status and their relations to dietary habit and life style among early adolescents in preparatory schools (EAPS) in the GS. Methodology: A cross sectional study had been performed on EAPS attendance aged 12-15 years old. Three areas in the GS were chosen randomly and pupils of 7th, 8th and 9th grades were selected by systematic random sample from six preparatory schools (two schools in each area). Questionnaires include Socio-Economic Status (SES), anthropometrics (weight and height) dietary habit and physical activities of pupils were collected. Serum zinc and iron, and Hb were measured. SPSS was used to analyze the obtained data. Results: The overall prevalence of serum zinc and iron deficiency among EAPS in the GS was 42.5% and 23.6%, respectively. The deficiencies of zinc and iron were more prevalent among the females (47.7%, 31.4%) than the males (37.2%, 15.9%) respectively. The overall anemia (low Hb level) among both genders was 34.5%. The overall prevalence of high body mass (overweight and obesity) was 29%. The overall prevalence of stunting was 7.6%. The stunted males (8.8%) were more prevalent than the females (6.4%). The results show that there are about 49% of the females exhibited sedentary life style, whereas 55% of the males practiced active and very active life style physical activities. Females were less consuming of food item (meat, eggs, milk) than males. Significant statistical differences (P<0.05) were observed between both genders in serum iron and Hb, but it was not in serum zinc level. Serum zinc level is associated with serum iron level, consumption of meat, BMI for age, stunting and physical activities. Moreover, statistical significant differences were found between iron level and Hb, egg, meat and liver consumption. Conclusion: Zinc and iron deficiencies are prevalent among EAPS in the GS. Serum levels of both elements were affected by the frequency of consumption of animal food sources. Zinc and iron deficiencies are associated with the life style characteristic of EAPS in the GS. Key words: Serum zinc, serum iron, early adolescent preparatory schools, physical activity, dietary habit, BMI, the Gaza strip
