目的：探讨膳食因素对新诊断2型糖尿病患者血糖变化的影响。方法在四川省遂宁市中心医院门诊患者中新确诊为2型糖尿病者作为研究对象并进行为期1年的治疗随访,在进行第二次血糖检查时对研究对象的基本情况、既往两次检查期间的饮食情况进行调查,并收集调查对象最近1年内的2次空腹血糖指标值；分析调查对象膳食因素对血糖值前后变化的影响。结果本研究共调查297名2型糖尿病患者,第二次血糖检查发现,有208例血糖升高,89例血糖降低。经多因素Logistic回归分析显示：膳食因素中,蔬菜类食物(=0.022)、水果类食物(=0.007)的摄入与2型糖尿病之间存在负关联,OR值及95%CI分别为：0.733(0.611~0.880)、0.591(0.480~0.727)；动物性食物的摄入与2型糖尿病之间存在正关联(=0.013),OR值及95%CI为：1.530(1.235~1.894)。非膳食因素中,吸烟(=0.002)、饮酒(=0.005)与2型糖尿病之间存在正关联,OR值及95%CI分别为：2.130(1.352~3.356)、1.173(0.239~4.694)；参加体育锻炼的频率(=0.031)与2型糖尿病之间存在负关联,OR值及95%CI为：0.159(0.072~0.350)。结论增加蔬菜类、水果类食物的摄入量,减少动物性食物的摄入量,同时健康的生活方式戒烟限酒加强体育锻炼,可显著改善和控制糖尿病患者血糖升高水平。“,”Objective To Investigate the main foods or food groups on the changes of glucose in type 2 diabetes mel itus patients. Methods Select type 2 diabetes in Suining Central Hospital. During the second blood glucose investigate the basic situation and dietary situation of the patients. Multivariate Logistic regression analysis was used to filter the dietary factors af ect blood sugar. Results This study investigated a total of 297 type 2 diabetic patients, the second blood examination revealed that there are 208 people elevated blood sugar, lower blood sugar 89 people. Multivariate Logistic regression analysis showed:dietary factors, vegetables ( =0.022), fruits ( =0.007) intake and type 2 diabetes, there is a negative correlation between, OR and 95%CI values were:0.733 (0.611~0.880), 0.591 (0.480~0.727);animal food intake and type 2 diabetes, there is a positive cor elation between ( =0.013), OR and 95%CI value were:1.530 (1.235~1.894). In non-dietary factors, smoking (P=0.002), alcohol consumption ( =0.005) and type 2 diabetes, there is a positive correlation between, OR and 95%CI values were:2.130 (1.352~3.356), 1.173 (0.239~4.694);participate in physical activity frequency ( =0.031) and type 2 diabetes, there is a negative cor elation between, OR and 95%CI value were:0.159 (0.072~0.350). Conclusion Add vegetables, fruits food intake and reduce the intake of animal foods, and healthy lifestyle quit alcohol limit physical activity, can significantly improve the control of diabetes and blood glucose levels rise.
