RESUMO
Objective To investigate the relationship between glycemic index (GI) of mixed foods and glucose and lipid metabolism index in elderly patients with diabetes mellitus, and to analyze the effects of CI response with regard to sex and obesity. Methods Forty-three patients with diabetes mellitus were divided into two groups with randomly crossover methods: high CI group and low GI group. Mixed meals were given for ten weeks (washing time:2 weeks). The biochemistry index and anthropometric index at baseline,before and after the first and second phase were measured. At the same time,fasting blood glucose(FBG)and postprandial 2 h blood glucose (2hBG) were supervised thrice a week and the daily energy, three macronutrients, and GI were calculated during trial. Results GI was positively correlated with FBG, 2hBG, homeostasis model assessment of insulin resistance ( HOMA-IR) ,body mass index ( BMI), and low-density lipoprotein cholesterol ( r = 0. 097-0. 423, P = 0. 000 1-0.01). GI value was a strong associated factor for FBG and 2hBG in overweight male patients. Conclusions The GI of mixed foods can better reflect the level of glucose response, especially in obese men. And it had good correlations with other metabolic indexes.
RESUMO
Based on Shanghai Guideline for Diabetes Prevention and Treatment(2005), 578patients with diabetes or abnormal glucose metabolism in Shi Men Er Road Community were managed at different levels during the past 2 years. Seventy percent of the patients were identified by general practitioners. Follow-up was initiated by general practitioners(60%)or other healthcare providers(40%).Our findings suggested that traditional disease management model focused mainly on acute conditions, while community health center-based model Was expected to meet the need for chronic disease prevention and treatment and play an important role in minimizing economic burden and improving doctor-and-patient relationship.
