Objective To explore main food,food categories and health related behavior′s influence on type 2 diabetes patients blood glucose change. Methods Selected 320 type 2 diabetes patients admitted in the endocrinology department from January,2012 to December,2013. Treated them for a year and did follow-ups. Carried out a questionnaire survey about patients' basic information,diet condition,and health related behavior using self-designed questionnaire form. Results 297 type 2 dia-betes patients were investigated in this research. There were 208 blood glucose rising cases and 89 blood glucose reducing cases at the second blood glucose examination. Ingesting vegetables and fruits was negatively correlated with type 2 diabetes (OR=0.733,0.591;95% credibility interval:0.611-0.880,0.480-0.727,P=0.022,0.007). Ingesting animal food was positively corre lated with type 2 diabetes(OR=1.530;95%credibility interval:1.235-1.894,P=0.013). Smoking was positively correlated with type 2 diabetes (OR=2.130;95%credibility interval:1.352-3.356,P=0.002). The frequency of doing physical exercise was nega tively correlated with type 2 diabetes(OR=0.159;95%credibility interval:0.072-0.350,P=0.031). Conclusion Increase vegeta-bles and fruits intake,and reduce animal food intake. Meanwhile,healthy lifestyle such as giving up smoking,restricting alchohol, and reinforcing physical exercise can remarkably improve and control diabetes patients′blood glucose level.%目的：探讨主要食物或食物类别及健康相关行为对2型糖尿病患者血糖变化的影响。方法选择2012年1月至2013年12月该院内分泌科确诊为2型糖尿病患者320例，进行为期1年的治疗及随访，采用自行设计调查表对患者基本情况、饮食情况、健康相关行为等进行问卷调查。结果该研究共调查297例2型糖尿病患者，第2次血糖检查发现血糖升高208例，血糖降低89例。饮食因素中蔬菜类、水果类食物的摄入与2型糖尿病呈负相关[优势比（OR）=0.733、0.591，95%可信区间：0.611~0.880、0.480~0.727，P=0.022、0.007]，动物性食物的摄入与2型糖尿病呈正相关（OR=1.530，95%可信区间：1.235~1.894，P=0.013）。非饮食因素中吸烟与2型糖尿病呈正相关（OR=2.130，95%可信区间：1.352~3.356，P=0.002），参加体育锻炼的频率与2型糖尿病呈负相关（OR=0.159，95%可信区间：0.072~0.350，P=0.031）。结论增加蔬菜、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，如戒烟、限酒、加强体育锻炼等可显著改善和控制糖尿病患者的血糖水平。
