title: Iron profile and dietary pattern of primary school obese Egyptian children.
abstract: BACKGROUND
  Poor iron status affects billions of people worldwide. The prevalence of obesity continues to rise in both the developed and developing nations. An association between iron status and obesity has been described in children and adults. The aim of the study was to assess the iron profile and dietary pattern in primary school-aged obese Egyptian children.
  
  
  METHODS
  A case-control study was conducted on 120 children, both obese (n=60) and control group (n=60), recruited from three primary governmental schools located in Dokki Sector, El-Giza Governorate, Egypt. Their ages ranged from 6 to 12 years. All children were subjected to full medical and dietetic history, anthropometric measurements, thorough clinical examination, and determination of complete blood count, serum iron, total iron-binding capacity, transferrin saturation (TS), and ferritin.
  
  
  RESULTS
  Despite similar dietary iron intake in the two groups, obese children showed highly significantly decreased hematocrit, mean corpuscular volume, mean corpuscular hemoglobin, serum iron, and TS, and increased mean corpuscular hemoglobin concentration and total iron-binding capacity when compared with the nonobese group. The obese group showed a highly significant increased rate of iron deficiency (ID) (TS<15% or mean corpuscular volume<76 fl) when compared with the nonobese group. Obesity was a significant risk factor for the development of ID (odds ratio: 7.09, 95% confidence interval: 3.16-15.92).
  
  
  CONCLUSIONS
  The association between ID and obesity may have important public health and clinical implications. For primary school children with elevated BMIs, screening for ID should be considered. Increasing awareness of the importance of physical activity and carrying out nutritional education programs are required.
