社区2型糖尿病患者HbA1c水平与营养状况的关系研究

Objective To explore the possible correlation between HbA1c level and nutritional status in community.based patients with type 2 diabetes.Methods A totaI of 219 type 2 diabetes patients were assigned into 2 groups:one with HbAIc<6.5%(n:108)and HbA1f≥6.5%(n=111).Metabolic parameters,food components.and nutritional status were compared between 2 groups.Results (1)49.32% of the participants attained HbA1c<6.5%.(2)HbA1c level was positively correlated with fasting plasma glucose,postprandial plasma glucose,and homeostasis assessment for insulin resistance(HOMA-IR)(r were 0.56,0.49,and 0.20,respectively,P<0.05 or P<0.01),but negatively correlated with high-density lipoprotein-cholesterol(HDL-C)(r=0.16,P<0.05).(3)Linear regression analysis showed that energy,carbohydrate,protein,and fat were the independent risk factors of HbA1c(all P<0.05).(4)Patients with HbA1c<6.5%consumed more fruits.The intake of pure energy-providing foods and protein-,fat-,or saturated fatty acid-rich foods were more frequent in patients with HbA1c≥6.5%(P<0.05).(5)The linear regression revealed that HbA1c level were decreased 0.36%(P<0.10)or 0.46%(P<0.01)by intake of more fruits,roughage and beans,and HbA1c levels were also decreased 0.42%(P<0.05)or 0.37%(P<0.10)by intake of less meat or oils.Conclusions In communitybased patients with type 2 diabetes mellitus,the incidence of HbA1c<6.5% remains low,There exists great difference in nutritional status between the groups with high and low HbA1c levels.The impact of diet OB HbA1c level is great.It's necessary to emphasize the importance of diet therapy far better diabetes control.
