Atherosclerotic risk factors associated with cardiorespiratory fitness and BMI in adolescents

DOI: 10.1590/S0004-27302008000600014

Previous research has demonstrated high prevalence of atherosclerotic risk factors in adolescents; however, the associate factors related to its onset are unclear. Therefore, the objective of this study was to relate inadequate blood pressure levels, total cholesterol (TC), HDL-C, LDL-C and triglycerides (TG) with different VO_2máx and BMI levels in a sample of 249 adolescents, aged between 12 to 16 years old. For VO_2máx prediction, the 20 meters test was used. The BMI was calculated using the body mass/heigh² equation. The considerate inadequate levels were: blood pressure > 90th percentile; total cholesterol > 150 mg/dL; LDL-C > 100 mg/dL, TG > 100 mg/dL and HDL-C <45 mg/dL. Logistic regression was used as statistical procedures, with p<0.05. For the boys, significant associations were observed between the low VO_2máx with TC (OR 4.33; IC=1.23-15.20) and TG (OR=4.88; IC=1.15-20.79) and between overweight and TG (OR=4.33; IC=1.42-13.21). After BMI correction, the males subjects with low VO_2máx maintained their significant associations with TC (OR=5.73; IC=1.52-21.58) and TG (OR=3.81; IC=1.86-16.94). The evidences in this study suggested an inverse relationship of the cardiorespiratory fitness with TC and TG for boys, independently of the BMI.
