The objective of this study was to correlate CRF with cardiovascular risk factors in T1DM children.
Methods: Fifty children and adolescents aged between 9 and 17 years with no diabetes complications and a mean diabetes duration of 4.6 years were selected. Antropometric, sexual maturation and blood pressure data were evaluated. CRF level was assessed with a 20-m shuttle run test. Laboratory tests were performed to verify fasting lipids and glycated hemoglobin. Statistical analyses were made with Pearson partial correlation, t test, and one-way ANOVA, with p≤0.05.
Results: After adjustment for body adiposity and sexual maturity, inverse correlations among CRF and TC, TG, TC/HDL-C, TG/HDL-C, non-HDL-C, and SBP were statistically significant. Variables differing by sex included weight Z score, BMI Z score, skinfold thickness, percentage of body fat, and DBP. Boys had higher CRF compared to girls. CRF and TC differed significantly by sexual maturation status.
Conclusion: An inverse and significant relationship between CRF and most lipid profile's components and SBP in poor controlled T1DM children and adolescents was found, independently of body adiposity.
