Background: Childhood obesity could induce some risk factors for cardiovascular disease (CVD) including serum lipid abnormalities, hypertension, and atherosclerosis. The present study aimed to comparison the lipid profile in normal children with cases having overweight, obesity and central obesity., Methods: In this case control study, which was conducted 2013, serum lipids for three groups of children including cases with overweight (Body mass index (BMI): 85-95th percentiles to age and sex and waist circumference (WC) <90th percentile to age and sex = Case group1), central obesity without general obesity (BMI <85th percentiles and WC ≥ percentile 90 = Case group 2) and central obesity with general obesity (BMI ≥95th percentile and WC ≥ percentile 90 = Case group 3) were compared with control group (BMI < 85th percentiles WC <90th percentile). Data were analyzed using software SPSS-16 by chi-square and ANOVA tests at significance level α=0.05., Results: Each group consisted of 100 individuals. The highest mean of serum lipids and the highest extent of dyslipidemia existed in the children having central obesity along with general obesity. So that 49%, 28%, and 38% students of this group show hypertriglyceridemia, hypercholesterolemia, and low high-density lipoprotein cholesterol (HDL-C). Odd ratio of hypertriglyceridemia, hypercholesterolemia and low HDL-c, in children with at least one abnormal index (BMI and /or WC) compared with control group were 3.73 (95% CI: 1.98, 6.99), 1.37 (95% CI: 1.71, 2.65) and 2.98 (95% CI: 1.51, 5.87), respectively., Conclusions: With regard to the relationship between central obesity and adverse changes in lipid profiles, the screening children for central obesity to prevention of cardiovascular disease are recommended.

Background: Prevalence of obesity in children has been increasing during recent decades all over the world. Obesity, particularly central obesity, is associated with metabolic syndrome and cardiovascular diseases. The present study aimed to assess obesity and central obesity in 6-11 year old Birjand elementary school children, East of Iran., Methods: This cross-sectional study was conducted on 1541 elementary school children, i.e. 851 girls and 690 boys, selected from Birjand elementary schools through multiple-cluster sampling in 2012. In order to determine overweight and obesity the percentile of CDC was used, so that, 85-95th percentile were taken as overweight and >95th percentile was defined as obese with respect to age and sex. For determination of central obesity, waist circumference and the ≥90th percentile were used regarding age and sex. The obtained data was analyzed by means of SPSS software (V: 15) using t and chi-square statistical tests at the 0.05 significant level., Results: Out of the studied children, 9.6% (11% of boys and 8.3% of girls) were overweight and 9.2% of children (i.e. 10.9% of boys and 7.9% of girls) were obese. About 15.7% of children (i.e. 20.3% of boys and 12% of girls) had central obesity., Conclusions: Regarding high prevalence of obesity, central obesity, and overweight in Birjand elementary school children, it is recommended that families should be provided with necessary information with respect to correcting life-style and preventing obesity in children.
