目的为了解代谢综合征(MS)、腹部肥胖、空腹血糖升高与餐后血糖异常的关系,提示中老年人餐后血糖异常(AGT)的风险,为早期发现糖尿病提供指导。方法横断面研究,分别用美国NCEP和国际糖尿病联盟的标准诊断MS。结果共有632例参加者,AGT检测率为34.02%。MS和空腹血糖升高可使AGT的风险增加3倍多,OR(95%CI)分别为3.09(2.18～4.40)和3.20(2.24～4.56)。腹部肥胖使AGT的风险增加2倍多,OR(95%CI)为2.07(1.43～2.99)。随着MS指标数聚集数的增多,AGT的危险随之增高。在血糖正常的情况下,MS指标聚集数依然有增加AGT风险的趋势。结论 MS、空腹血糖升高、腹部肥胖的人群当及时进行餐后血糖检测,以早期发现糖尿病风险。
Objective To understand the relationship between metabolic syndrome (MS), abdominal obesity, elevated fasting plasma glucose and postprandial blood glucose abnormality, and to indicate the risk of postprandial blood glucose abnormality (AGT) in middle-aged and elderly people and to provide guidance for the early detection of diabetes mellitus. Methods Cross-sectional studies were performed to diagnose MS using the NCEP and the International Diabetes Federation criteria, respectively. Results A total of 632 participants, AGT detection rate was 34.02%. MS and elevated fasting glucose increased the risk of AGT by more than 3-fold, with OR (95% CI) of 3.09 (2.18 to 4.40) and 3.20 (2.24 to 4.56), respectively. Abdominal obesity increased the risk of AGT by more than two-fold, OR (95% CI) 2.07 (1.43-2.90). With the increase of MS index number, the risk of AGT increases. In the case of normal blood glucose, MS index aggregation still has the tendency to increase the risk of AGT. Conclusions MS, fasting blood glucose, abdominal obesity should be promptly tested for postprandial blood glucose in order to detect the risk of diabetes early.
