目的采用1997年及2003年美国糖尿病协会(ADA)标准诊断社区老年人空腹血糖受损(IFG)情况,并随访其对转归的影响。方法2004年,对贵州省贵阳市城区1 645名老年人进行调查,2008年随访2004年空腹血糖正常(normal fasting glucose,NFG)人群IFG的发病情况、IFG转化为糖尿病(DM)情况、IFG患者心血管疾病的发病情况。结果基线人群按2003年ADA标准诊断IFG患病率为22%,按1997年ADA标准诊断IFG患病率为11%,1997年ADA诊断IFG患者高血压与冠心病的患病率高于2003年ADA的标准。2008年随访人群中,2003年ADA标准IFG的发病率为7.3%,1997年ADA标准为3.6%;2种标准诊断为IFG转归构成情况差异有统计学意义。结论IFG对DM的预测有重要作用。不同的标准诊断IFG的患病率不同,4年随访并未显示出其对老年人发生糖尿病、高血压、冠心病不同的预测作用。
OBJECTIVE: To assess the impact of impaired fasting glucose (IFG) on the elderly population in the community using the American Diabetes Association (ADA) Methods In 2004, 1 645 elderly people in Guiyang City, Guizhou Province were investigated. In 2008, the incidence of IFG in normal fasting glucose (NFG) population and the conversion of IFG to diabetes mellitus (DM) The incidence of cardiovascular disease. Results The baseline prevalence of IFG was 22% according to the ADA criteria of 2003, and the prevalence of IFG was 11% according to ADA criteria of 1997. The prevalence of hypertension and coronary heart disease in ADG diagnosed by ADA in 1997 was higher than that of 2003 ADA standards. In 2008, the incidence of ADA standard IFG was 7.3% in 2003 and 3.6% in 1997, respectively. There were significant differences in the composition of IFG between the two kinds of standard diagnosis. Conclusion IFG plays an important role in the prediction of DM. Different standard diagnosis of IFG prevalence of different, 4-year follow-up did not show the elderly with diabetes, hypertension, coronary heart disease, the different predictors.
