目的分析住院T2DM患者HbA1c水平与FPG和果糖胺(FRU)之间的相关性。方法选取432例住院T2DM患者,按HbA1c水平分为<6.5%、6.5%～7.5%和>7.5%3组。分析各组HbA1c与FPG、FRU之间的相关性。结果 HbA1c<6.5%组,HbA1c与FPG和FRU之间无相关性(r=0.254,P=0.108;r=-0.032,P=0.884),TG与HbA1c呈正相关(r=0.342,P=0.031);6.5%～7.5%组,HbA1c与FPG和FRU之间无相关性(r=0.153,P=0.151;r=0.167,P=0.132),WHR与HbA1c呈正相关(r=0.230,P=0.035);>7.5%组,HbA1c与FPG和FRU呈正相关(r=0.522,P=0.000;r=0.770,P=0.000)。各年龄段患者(<65岁,65～80岁,>80岁)HbA1c与FPG和FRU之间均呈正相关(r=0.2193～0.2921,P<0.01;r=0.6525～0.7436,P<0.01)。结论住院的HbA1c<7.5%的T2DM患者,FPG、FRU与HbA1c水平无相关性,三指标间的一致性较差。
Objective To analyze the correlation between HbA1c level and FPG and fructosamine (FRU) in hospitalized patients with T2DM. Methods Forty-two inpatients with T2DM were enrolled and divided into three groups according to the level of HbA1c: <6.5%, 6.5% -7.5% and> 7.5%. The correlation between HbA1c, FPG and FRU in each group was analyzed. Results There was no correlation between HbA1c and FPG and FRU (P = 0.108; r = -0.032, P = 0.884), HbA1c was positively correlated with HbA1c (r = 0.342, P = 0.031) (R = 0.153, P = 0.151; r = 0.167, P = 0.132). There was a positive correlation between WHR and HbA1c (r = 0.230, P = 0.035) ;> 7.5%, HbA1c was positively correlated with FPG and FRU (r = 0.522, P = 0.000; r = 0.770, P = 0.000). There was a positive correlation between HbA1c and FPG and FRU in patients of all ages (<65 years, 65-80 years,> 80 years old) (r = 0.2193-0.2921, P <0.01; r = 0.6525-0.7436, P <0.01). Conclusions There is no correlation between FPG, FRU and HbA1c levels in hospitalized patients with HbA1c <7.5% T2DM, and the consistency between the three indexes is poor.
