Epidemiological Investigation on Diet and Drugs of Adult Diabetes Mellitus in Guangdong Province

Objective: To study the epidemiological characteristics of adult diabetes, and effect of food composition on blood glucose in Guangdong Province. Methods: The data of this study were from the China DiaChronic Study. This study investigated diabetic patients in eight urban and rural centers in Guangdong Province. Questionnaire survey, physical examination and fundus photography were carried out, and blood and urine indexes were measured. All 1621 subjects were finally included. Results: (1) The prevalence rates of obesity, hypertension, hypertriglyceridemia, hyper LDL-C, were 15.8%, 37.9%, 50.5% and 79.3% respectively. The prevalence rates of diabetic nephropathy and retinopathy were 33.6% and 16.7% respectively. The treatment rate of subjects was 93.6%, and the compliance rate of HbA1c of them was 49%. (2) In all subjects, the median of total caloric intake of food was 1660 kcal/d, of which grains account for the most with 810 kcal, and milk were the least with 0 kcal. Men's caloric intake in grains, livestock meat, poultry meat and aquatic products were significantly higher than that of women, while women's caloric intake in potatoes and milk were significantly higher than that of men (P<0.05). The caloric intake of grains, vegetables and livestock meat in rural were significantly higher than that in urban, while the caloric intake of miscellaneous grains, potatoes, beans, fruits, milk, poultry meat, aquatic products, eggs and nuts in urban areas were higher than that in rural areas (P<0.05). For subjects with HbAIc<6.5%, the energy intake of vegetables, fruits, poultry meat and eggs was significantly higher than that of them with HbA1c>6.5% (P<0.05). Conclusion: Despite patients try to control blood glucose, half of them have poor blood glucose control. At present, the diet of rural residents mainly include grains, vegetables and livestock meat. Vegetables, fruits, poultry and eggs may be beneficial to blood glucose control, which needs further research to confirmation. Disclosure X.Chen: None. W.Jiang: None. F.Xiong: None. L.Yang: None.
