Association of lipids and antropometrics measures of adiposity in adolescents

Abstract

The arm of this study was to relate lipidic levels to global and central obesity in adolescents. Transversal, descriptive and co-relational study. 127 pubescent subjects took part in this study, 71 girls (13.39+1.81 years) and 56 boys (13.10+1.97 years). It was identified global adiposity through the body mass index (BMI) as well central adiposity through the waist circumference (WC), according to age, sex, and ethnics. It had been determined levels of total cholesterol (TC), high density lipoprotein (HDL-C), low density lipoprotein (LDL-C) and triglycerides (TG) after twelve hours of overnight fasting. The date had been analyzed through Chi-square test and Pearson`s correlation, considering the significance level of p<0.05. It had been identified increased levels of TC in the obese group (boys=61.90%; girls=56.89%) as well as in the non-obese group (boys=64.28%; girls=61.54%), without statistical difference. The HDL-C were lower in the boys obese group compared to the non-obese (64.29% vs 28.57%; p=0.019) and in the female obese group in relation to the non-obese (60.35% vs 23.08%; p=0.014). It was identified a greater proportion of TC surplus in he male obese group than in the non-obese (50% vs 14.29%; p=0.018). Positive associations were verified for logn TG and logn BMI (r=0.215; p<0.001) and logn TG e logn WC (r=0.210; p<0.001), negative relations were observed in logn HDL-C and logn BMI (r=-0.425; p<0.001) and logn TG and logn WC (r=-0.365; p<0.001). This study has shown greater proportion of decreased levels of TG in obese adolescents comparing to the non-obese. It was observed moderate inverse associations of HDL-C to the global and central adiposity.
