Glycemic control of newly-diagnosed type 2 diabetes with different baseline body mass index under the standardized metabolic disease management model

Abstract

Objective To explore the glycemic control of newly-diagnosed type 2 diabetes with different levels of baseline body mass index (BMI) after 6 months treatment under the standardized metabolic disease management model. Methods (1) 163 patients of newly-diagnosed type 2 diabetes were divided into normal weight (BMI 18.5-23.9 kg/m2), overweight (BMI 24.0-27.9 kg/m2), and obese (BMI≥28 kg/m2) groups according to baseline BMI, the blood glucose and lipids levels were compared among 3 groups. (2) The blood glucose levels were compared among 3 groups after 6 months of standardized management. (3) The overweight and obese patients were divided into group weight loss≥5% and group weight loss<5% or weight gain in 6 months. The blood glucose levels were compared. Results (1) At baseline, overweight and obese groups had higher homeostasis model assessment for insulin resistance and lower high density lipoprotein-cholesterol compared with normal weight group. (2) After 6 months of treatment, HbA1C and HbA1C reduction showed no difference among 3 groups (normal, overweight and obese) after adjusted by baseline HbA1C. The rate of HbA1C 0.05). (3) After 6 months of treatment, 32.28% overweight and obese patients lost weight by ≥ 5%, while HbA1Cand HbA1Creduction showed no difference between 2 groups (weight loss≥5% and weight gain or weight loss 0.05). Group weight loss≥5% had better glucose control (92.68% vs 77.91%, P<0.05). Conclusions As BMI increased, insulin resistance and lipid disorders were more serious in newly-diagnosed type 2 diabetes. After 6 months of standardized metabolic management, newly-diagnosed type 2 diabetes with different baseline BMI and weight changes both achieved good glycemic control. In addition, patients losing weight equal to or more than 5% achieved higher attainment of HbA1C targets. Key words: Newly-diagnosed type 2 diabetes; Body mass index; HbA1C; Weight changes
