目的分析高甘油三酯腰围表型(HW)青少年心血管危险因素状态。方法选取秦皇岛地区1665名13～15岁青少年进行流行病学调查,测量身高、体重、腰围(WC)、血压、空腹血糖(FPG)、血甘油三酯(TG)和高密度脂蛋白胆固醇(HDL-C)。HW定义为WC≥年龄、性别特异的80百分位点并且TG≥1.24mmol/L。据腰围及甘油三酯水平,分为A组:WC和TG均正常组;B组:单纯WC或TG高;C组:WC和TG均高组。结果①HW患病率为7.0%,男、女分别为6.9%和7.2%,不同性别HW患病率比较差异无统计学意义(χ2=0.077,P=0.781)。②校正年龄、性别后应用协方差分析,三组间各指标比较差异均有统计学意义(P<0.05)。应用LSD法进行两两比较,B组和C组体质量指数(BMI)、WC、收缩压(SBP)、舒张压(DBP)、FPG及TG水平均高于A组,HDL-C水平均低于A组(P<0.05)。C组BMI、WC、SBP及TG水平高于B组,HDL-C水平低于B组(P<0.05)。结论HW青少年存在更为严重的代谢异常。HW是一种简单、便宜方法,可用于评价心血管危险因素的聚集情况。
Objective To analyze the status of cardiovascular risk factors in hypertriglyceridemic waist circumference (HW) adolescents. Methods A total of 1665 adolescents aged 13 to 15 years from Qinhuangdao were enrolled in this study. Epidemiological survey was conducted to investigate the relationship between height, weight, waist circumference (WC), blood pressure, FPG, TG and HDL -C). HW was defined as WC ≥ 80% age- and sex-specific and TG ≥ 1.24 mmol / L. According to the waist circumference and triglyceride level, divided into A group: WC and TG are normal group; B group: simple WC or TG high; C group: WC and TG are high group. Results ①WH prevalence was 7.0%, male and female were 6.9% and 7.2%, respectively. There was no significant difference in the prevalence of HW among different sex (χ2 = 0.077, P = 0.781). (2) After adjusting for age and sex, covariance analysis was used. The differences among the three groups were statistically significant (P <0.05). The body mass index (BMI), WC, systolic blood pressure (SBP), diastolic blood pressure (DBP), FPG and TG in group B and group C were all higher than those in group A, and the levels of HDL-C In group A (P <0.05). The levels of BMI, WC, SBP and TG in group C were higher than those in group B, while the levels of HDL-C in group C were lower than those in group B (P <0.05). Conclusion HW adolescents have more serious metabolic abnormalities. HW is a simple, inexpensive method that can be used to assess the aggregation of cardiovascular risk factors.
