The prevalence of obesity continues to rise all around the world       (1, 2, 3). Obesity is associated with important complications such as coronary heart disease and diabetes (3,5). Obese children because of their inappropriate diets and consumption of energy dense foods which lack adequate minerals, may be at increased risk of micronutrient deficiencies. So in this study we tried to figure out if there is any association between low levels of  micronutrients such as iron , calcium and phosphorus and obesity.
Materials and Methods
A total of 280 obese and 280 non obese children ranging between 2-16 years old were evaluated. BMI>= 85% was defined as overweight. Serum iron, ferritin, TIBC, MCV, hemoglobin, hematocrit, calcium and phosphorus levels were evaluated in both groups.Then the data were compared.
In obese children 94.3% had hemoglobin in the range of anemia where this was 60% in control group. Serum iron was low in 56.1% of obese children vs 10.4% in control group. Serum level of calcium and phosphorus was significantly lower than normal in obese children.
This study's results show the significant impact of healthy nutrition on the overall health of the society and also show the effect of healthy nutrition on preventing obesity and it's complications.
