摘要 目的探讨糖化血红蛋白(HbA1c)达标(HbA1c<7.5%)的老年2型糖尿病患者HbA1c与血糖波动的关系。方法选取HbA1c<7.5%的住院老年糖尿病患者100例,采用动态血糖监测系统(CGMS)进行3d的血糖监测,分析血糖波动情况,计算平均血糖、高血糖持续时间以及平均血糖漂移幅度(MAGE),分析HbA1c与上述测定值之间的相关性。结果59.5%的患者血糖最高值超过11.1mmol/L,29.7%的患者发生低血糖(<3.9mmol/L);血糖超过7.8mmol/L占全天的时间百分比为33%;血糖超过11.1mmol/L占全天的时间百分比为(10.2±1.2)%;低血糖占时间百分比(5.2±1.5)%;HbA1c与CGMS平均血糖值呈显著正相关(r=0.55,P<0.01),与高血糖持续时间相关(r=0.48,P<0.01),与MAGE无关(r=0.12,P>0.05)。结论HbA1c达标的老年2型糖尿病人血糖波动大;HbA1c与平均血糖以及高血糖持续时间相关,与血糖波动无关;HbA1c和血糖波动是评价血糖控制的量与质的独立指标。
