Comparison of two metabolic risk scores in obese adolescents – whether the inclusion of cardiorespiratory fitness matters? – a pilot study

Various approaches are used for calculation of cardiometabolic risk in youth, including continuous scores (cMS), which are commonly expressed as sum of age and sex specific z-scores for waist circumference (WC), triglycerides (TG), high-density cholesterol (HDL), glucose (BG) and systolic blood pressure (SBP). Recently, a novel, easier to calculate continuous pediatric risk score (PsiMS) has been developed. Purpose: To investigate the correlation of PsiMS and cMS scores and to explore whether the inclusion of cardiorespiratory fitness (CRF) alters the score. Methods: Data on 30 obese adolescents (BMI ≥95th percentile, mean age 13.7 years, 15 female/15 male) were retrospectively analysed. PsiMS and cMS scores were calculated using the same set of variables (WC, TG, HDL, BG, SBP), with or without CRF included. Results: PsiMS score calculated as (2xWC/height) + (BG (mmol/l)/5.6) + (TG (mmol/l)/1.7) + (SBP (mmHg)/130) - (HDL (mmol/l)/1.02) correlated well with cMS score (Spearman’s rang order correlation coefficient 0.80, p<0.01). Very high correlation was found between PsiMS scores calculated with/without CRF (0.99, p<0.01). Conclusion: PsiMS score represents a practical and accurate score for evaluation of cardiometabolic risk in obese youth. Inclusion of CRF in PsiMS score does not change the risk score.
