Relationship of body mass index with serum lipids in elementary school students.
OBJECTIVE
To determine the relationship of body mass index with serum lipids in elementary students.


METHODS
This prospective analytic study was conducted among 954 elementary school students (9-11 years), selected by multi stage random systematic method from 6 cities and their rural areas from The South Khorasan province (eastern Iran) from September to December 2006. Height and weight was measured and Body mass index was calculated. Total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C) and high-density lipoprotein cholesterol (HDL-C) were determined.


RESULTS
954 students 9-11 years old were studied. 45.4% were boys. 76.5% were living in the city. 1.8% of students were obese and 3.4% were over weight. There was no significant relation between obesity and overweight with sex, age and the area of residence. There was significant relation between BMI with TC (P= 0.003), TG (P< 0.001) and LDL-C (P= 0.04). TG was significantly higher in obese and overweight students than in normal weight students (P< 0.001). TC (0.002) and LDL-C (0.01) were significantly higher in obese students than normal weight students. The prevalence of high TG was significantly higher in obese and overweight students than normal weight students (0.003). There was no significant difference between different kinds of dyslipidemia with area of residence.


CONCLUSIONS
it is necessary to measure serum lipid profile in obese and overweight children.
