BACKGROUND/OBJECTIVES:Obesity is associated with increased triglyceride levels. We examined whether overall obesity (body mass index (BMI)) and abdominal obesity (waist circumference (WC)) are independently associated with hypertriglyceridemia among the Korean population. SUBJECTS/METHODS:A national sample of 5036 Koreans aged 19-64 was examined with cross-sectional surveys, the Korea National Health and Nutrition Examination Survey, in 2007 and 2008. BMI, WC and other lifestyle information were assessed. RESULTS:We documented 1344 cases (26.7%) of hypertriglyceridemia (fasting triglycerides of >150 mg/dl). Both BMI and WC were each independently associated with hypertriglyceridemia. Multivariate odds ratios (ORs) of increasing categories of BMI (<18.5, 18.5≤ - <23, 23≤ - <25, 25≤ - <28, ≥28 kg/m²), were 0.49, 1.00 (reference), 1.26, 1.63 and 1.84, respectively (P=0.0007) adjusting for WC. There was a positive association between WC and hypertriglyceridemia across increasing quintiles of WC (multivariate-adjusted ORs: 1.00 (reference), 1.54, 2.54, 2.21 and 2.36; P<0.0001), adjusting for BMI. WC was positively related to hypertriglyceridemia in both gender. However, only women's BMI was independently associated with hypertriglyceridemia after adjusting for WC. The joint relation between BMI and WC and hypertriglyceridemia showed that within each BMI category, higher WC predicted a greater prevalence of hypertriglyceridemia and vice versa. The receiver operating characteristic curves indicated that BMI (0.69) and WC (0.72) were similar in predicting hypertriglyceridemia. CONCLUSIONS:Both BMI and WC were strongly independently associated with hypertriglyceridemia among the population. Both measurements should be considered for use in assessing health risk at clinical settings and epidemiologic research among Asian population.

背景/目的:肥胖与甘油三酯水平升高有关。我们检查了总体肥胖(体重指数(BMI))和腹部肥胖(腰围(WC))是否独立于韩国人群中的高甘油三酯血症。
主题/方法:在2007年和2008年,通过横断面调查(韩国国民健康与营养检查调查)对5036名19-64岁的韩国人进行了全国抽样调查。对BMI,WC和其他生活方式信息进行了评估。
结果:我们记录了1344例(26.7%)高甘油三酯血症(空腹甘油三酯>150μmg/ dl)。 BMI和WC都分别与高甘油三酯血症相关。体重指数不断增加的类别(<18.5,18.5≤9-<23,23≤-<25,25≤-<28,≥28kg /m²)的多元优势比(OR)为0.49,1.00(参考),1.26,分别为WC调整为1.63和1.84(P = 0.0007)。在增加的五分位数的WC中,WC与高甘油三酯血症之间存在正相关(多变量调整OR:1.00(参考值),1.54、2.54、2.21和2.36; P <0.0001),并针对BMI进行了调整。 WC与男女高甘油三酯血症均呈正相关。但是,只有女性的BMI在调整WC后才独立地与高甘油三酯血症相关。 BMI和WC与高甘油三酯血症之间的联合关系表明,在每个BMI类别中,较高的WC预测较高的高甘油三酯血症患病率,反之亦然。接收机的工作特性曲线表明,BMI(0.69)和WC(0.72)在预测高甘油三酯血症方面相似。
结论:人群中BMI和WC均与高甘油三酯血症密切相关。在亚洲人群中,两种测量都应考虑用于评估临床环境和流行病学研究中的健康风险。
