Evaluation of selected mineral concentrations in overweight and obese adolescents
Journal Title: MedPulse -International Medical Journal - Year 2015, Vol 2, Issue 6
Abstract
Background: Obesity is increasing all over the world in adolescents due to a decrease in physical activity and change in lifestyle. Studies showing an association between serum concentrations of minerals and insulin resistance in overweight and obese adolescents are lacking. Aims and objectives: To assess serum concentrations of calcium, magnesium and fasting blood glucose levels in over weight (and obese) adolescents and to determine the association between serum mineral concentrations with fasting blood glucose in them. Materials and Methods: A case control study was done involving 30 apparently normal overweight (> 95th percentile) aged between 12 – 19 years (cases), 30 age and gender matched normal weight (5th – 84th percentile) adolescents(controls) were randomly selected. Serum concentrations of calcium (Arsenazo III method), magnesium(colorimetric xylidyl blue method) and fasting blood glucose (trinder’s method) were assessed for both the groups along with anthropometric measurements height (cm), weight (kg), waist circumference (cm), BMI (kg/Sq.m) and the recording of pulse rate (manual) and blood pressure (mercury sphygmomanometer). Data was tabulated and statistically analyzed using SPSS software. Results and conclusions: Serum concentrations of calcium, magnesium and fasting blood glucose were statistically similar and within normal limits in both groups. However a significantly negative correlation was found between serum calcium and BMI, PR, SBP, FBS in cases. In contrast a significantly positive correlation was observed between serum magnesium and PR, SBP, and FBS in them; the cause of which is not known. Hence further studies are needed in this regard to confirm the observations obtained in this study.
