Abstract

The present study is aimed to assess the nutritional status and cognitive performances of 
some preschool children (57.2-71.39 months). The study was performed on 39 children 
51% were girls and 49% were boys with a mean age of 53.59±1.85 months. All children 
from cities Giza government. The obtained data showed that mean value body weight, 
height, body mass index (BMI), and mid upper arm circumference (MUAC) were
16.97±0.26 kg, 101.7±0.98 cm, 16.47±0.21kg/m2
, and 14.01±0.33 cm
respectively. According to the food intake analysis, the mean value intake of total energy, 
protein, fat, and carbohydrate was 985.08±32.79 kcal, 33.74±1.12 g, 33.98±1.28 g, and 
110.96±3.89 g respectively. The mean value intake of some minerals (Iodine, Iron, 
Selenium, and Zinc) was 81.64±5.49µg, 9.71±0.49 mg, and 42.79±2.67µg and 4.77±0.22 
mg respectively. The mean value intake of some vitamins (Vitamin A, Vitamin B1, 
Vitamin B2, and Vitamin C) was 273.23±25.57 I.U, 0.45±0.06 mg, 0.49±0.03 mg, and 
17.01±1.14mg respectively. Some biochemical analyses showed that the mean value 
urinary iodine was 159.55±3.08 µg/l, and blood hemoglobin was 11.5±0.10g/dl. The 
Wechsler tests were done to calculate student IQ, the mean value of verbal IQ was 
103.23±1.18, the mean average of performance IQ was 76.23±2.78, and the mean of total 
IQ was 94.61±0.93. Finally, this study is importance due to the lack of studies in this 
stage of childhood and so we recommended that to more investigation need to done at 
this stage of childhood especially with the increasing interest of the Egyptian government 
in the healthy nutrition of children.
