This study aimed to estimate the prevalence of abdominal obesity and investigate their association with parameters markers of metabolic syndrome (MS) and its risk factors in female adolescents. It is a cross-sectional study with 150 adolescents from 10 public schools in the Federal District, Brazil. The presence of abdominal obesity was considered by measuring waist circumference above the 80th percentile, according to Taylor et al. (2000). The associated factors included sociodemographic characteristics, health status of adolescents and their parents, physical activity, eating habits, blood pressure and biochemical profile. The abdominal obesity prevalence ratio (PR) was estimated by Poisson regression model, with 95% CI. Among the adolescents studied (age= 15.6 +/- 0.8 years; BMI = 21.0 +/- 3.0 kg/m2), prevalence of abdominal obesity was 20%, and this condition was not associated with sociodemographic variables, physical activity and diet. However, abdominal obesity was significantly associated with intake of less than 4 meals a day (PR = 2.27; IC95% 1.27-4.10), previous obesity (PR = 2.36; IC95% 1.31-4.01), history of parental chronic disease (PR = 3.55; IC 95% 1.63-7.75), fasting insulin = 15 uUi/mL (PR = 3.05; IC 95% 1.36-6.82) e HDL-c > 40 mg/dL (PR = 0.39; IC95% 0.23-0.67). In this population, modifiable factors, family history and determinants of MS, such as insulin and HDL-c were associated with abdominal obesity, which points to the need for effective health promotion among adolescents.
本研究旨在估计女性青少年腹部肥胖的患病率，并调查其与代谢综合征（MS）参数指标及其危险因素之间的关联。这是一项横断面研究，研究对象为来自巴西联邦区10所公立学校的150名青少年。根据泰勒等人（2000年）的研究，通过测量腰围高于第80百分位数来判定是否存在腹部肥胖。相关因素包括社会人口学特征、青少年及其父母的健康状况、身体活动、饮食习惯、血压和生化指标。采用泊松回归模型估计腹部肥胖患病率比（PR），并给出95%置信区间。在所研究的青少年中（年龄=15.6±0.8岁；体重指数=21.0±3.0kg/m²），腹部肥胖患病率为20%，且这种情况与社会人口学变量、身体活动和饮食无关。然而，腹部肥胖与以下因素显著相关：每天进餐少于4次（PR=2.27；95%置信区间1.27 - 4.10）、既往肥胖（PR=2.36；95%置信区间1.31 - 4.01）、父母慢性病病史（PR=3.55；95%置信区间1.63 - 7.75）、空腹胰岛素≥15uUi/mL（PR=3.05；95%置信区间1.36 - 6.82）以及高密度脂蛋白胆固醇>40mg/dL（PR=0.39；95%置信区间0.23 - 0.67）。在这一人群中，可改变因素、家族病史以及MS的决定因素，如胰岛素和高密度脂蛋白胆固醇，均与腹部肥胖相关，这表明有必要在青少年中开展有效的健康促进活动。
