摘要: 摘要:目的 比较超重和肥胖人群中, WHO 1999年、美国国家胆固醇教育计划成人治疗组第3次指南(NCEP-ATPⅢ)2001年和国际糖尿病联盟(IDF)2005年代谢综合征(MS)定义下的人群特征, 并对MS组分进行因子分析。方法 371例体重指数(BMI)≥23kg/m2患者采集人口统计学资料, 测定血脂、血尿酸和尿微量白蛋白等指标, 先后进行口服葡萄糖耐量试验和多样本的静脉葡萄糖耐量试验(FSIGTT), 应用不同定义分组后进行基线资料的比较和相关性分析。结果 FSIGTT结果显示, 所有超重和肥胖人群均存在不同程度的胰岛素抵抗。腰围与胰岛素敏感指数(SI)的相关性优于BMI与SI的相关性(相关系数分别为-0.198和-0.194, P<0.001)。28.8%(107例)的患者不符合任何一种MS定义; 50.4%(187例)符合ATP定义, 26.4%符合WHO定义, 63.1%(234例)符合IDF定义; ATP和IDF定义的符合率最高, 达70.3%, 两组人群特征基本一致; WHO组有较高的发病年龄、BMI偏低、显著升高的高胆固醇血症和显著升高的空腹和餐后血糖。MS组分评分分别与年龄、肥胖度和胰岛素抵抗成显著正相关和负相关, 与性别、体脂含量和急性胰岛素对葡萄糖反应指数无相关性。结论 超重和肥胖人群中一部分仅表现为单纯性肥胖和胰岛素抵抗。在发生MS人群中, 以IDF定义下的人群发病率最高。WHO定义因其对胰岛素抵抗评估的要求, 实用性差; ATP定义人群基本被IDF覆盖, 故可被IDF定义取代。体脂分布的异常(中心性肥胖, 而非体脂含量)加剧了代谢紊乱的发生, 与之相平行的是胰岛素抵抗程度。

Abstract: ABSTRACT:Objective To compare the characteristics of over weight and obesity subjects defined by three criteria:World Health Organization (WHO) in 1999, the National Cholesterol Education Program Adult Treatment Panel Ⅲ(NCEP-ATPⅢ) in 2001, and the International Diabetes Federation (IDF) in 2005. Methods Medical history collection, physical examination, oral glucose tolerance test (OGTT), and frequently sampled intravenous glucose tolerance test (FSIGTT) were performed in 371 subjects with body mass index (BMI)≥23 kg/m2. Fasting blood samples were taken to test lipid profiles,urea acid level and so on. Data was analyzed including comparison and relationship statistics. Results Data from FSIGTT showed that insulin resistance existed in all over weight and obesity subjects. The relationship between waist and sensitivity index (SI) was superior than that between BMI and SI (r=-0.198 and r=-0.194, P<0.001=. Totally 107 subjects (28.8%) did not meet any definitions, 187 (50.4%) met ATP definition, 98(26.4%) met WHO definition, and 234 (63.1%) met IDF definition. ATP and IDF definitions had the highest coincidence rate (70.3%), and subjects in these two groups almost had basically the same manifestations. The age of onset in WHO group was higher than those in other two groups. Meanwhile, subjects in the WHO group was cha- racterized by lower BMI, higher hyperlipidemia, and significantly increased fasting and postprandial blood glucose level. The MS component scores were positively correlated with age, BMI, waist, and waist-to-hip ratio (WHR), and were negatively correlated with SI. However, no correlation was found between MS component scores and gender, fat%, or acute insulin response to glucose index. Conclusions Some of over weight and obesity subjects only have insulin resistance and have no metabolism syndrome. The group defined by IDF criteria of the metabolic syndrome (MS) has the highest incidence rate. Limited by the requirements of insulin resistance evaluation, the definition proposed by WHO is somewhat unfeasible for practices. ATP definition may be replaced by IDF definition, because the populations defined by ATP definition is covered by the latter. Meanwhile, the abnormalities of fat mass distribution in the body (i.e., central obesity), rather than its contents, may exacerbate the occurrence of MS, as well as the development of insulin resistance.
