[Assessment of dietary calcium intake on metabolic syndrome frequency in obese children and adolescents].
BACKGROUND
High dietary calcium intake has an impact on reduction of adipose tissue, as in prevention and treatment of obesity and metabolic syndrome (MS). The aim of the study was to evaluate the influence of dietary calcium on appearance MS in children and adolescents.


METHODS
The study included 150 patients in the age range of 7-18 years with obesity. In each child, the bioelectrical impedance analysis, waist circumference, blood pressure, lipids (enzymatic method), Oral Glucose Tolerance Test (OGTT) with marking of glucose, insulin blood levels (RIA method), and estimation of nutritional status had been made. The standard deviation score of body mass index (SDS BMI), waist to hip ratio (WHR), insulin resistance (HOMA-IR) was calculated. MS was recognized according Cook criteria.


RESULTS
All patients had waist circumference greater than the 90 percentile. Boys had more often an abnormal lipids profile than girls. Both, high blood pressure and HOMA-IR >3 were found in over half of studied patients. The diet of many patients had too much fat and saccharose intaking. Only 20% of children consumed normal value of calcium. The observed intaking more than 20 mg of calcium per ideal body mass (i.b.m) per 24 hours had higher % FAT, SDS BMI, waist circumference, HOMA-IR, and insulin. MS was recognized more often in this group.


CONCLUSIONS
Insufficient dietary calcium intake could have an effect on some parameters of metabolic syndrome.
