目的探讨农村既往糖尿病患者糖尿病相关知识与空腹血糖控制之间的关联。方法采用分层整群抽样的方式,于2007年9～12月对湖北省宜昌市夷陵区35岁以上农村居民9871人(研究对象为有完整信息的既往糖尿病患者179人)进行问卷调查和血样生化检测。在控制了性别、年龄,教育水平、经济收入和合并症等变量的情况下,Logistic回归分析用于探索糖尿病患者的糖尿病相关知识及格率与空腹血糖达标率之间的关系,线性回归用于探索空腹血糖达标患者和空腹血糖未达标患者的糖尿病相关知识与空腹血糖之间的关系。结果糖尿病患者的空腹血糖达标率为49.7%。糖尿病相关知识及格率为27.4%。在控制了相关混杂因素的情况下,糖尿病患者的糖尿病相关知识及格率越高,则其空腹血糖达标率越低(OR=0.47,P﹤0.05);对于空腹血糖不达标的患者,糖尿病相关知识越好,则其空腹血糖越高(β=0.48,P﹤0.05)。结论糖尿病患者的糖尿病相关知识和血糖控制之间呈负相关。也许可以用“久病成良医”来解释,也就是因为血糖难以控制,因此患者会更主动获取糖尿病相关知识。
Objective To investigate the association between diabetes-related knowledge and fasting glucose control in rural diabetics. Methods A stratified cluster sampling method was used to survey 9 981 rural residents 35 years old and older (179 past diabetics with complete information) from Yiling District, Yichang City, Hubei Province from September to December 2007. Blood biochemical tests. Logistic regression analysis was used to explore the relationship between the prevalence of diabetes-related knowledge and the compliance rate of fasting blood glucose in diabetic patients, with the control of variables such as gender, age, educational level, economic income and comorbidity. Linear regression was used to explore The Relationship between Diabetes Related Knowledge and Fasting Blood Glucose in Fasting Blood Sugar Deficient Patients and Fasting Blood Glucose Patients. Results The compliance rate of fasting blood glucose in diabetic patients was 49.7%. The prevalence of diabetes-related knowledge was 27.4%. In control of related confounding factors, the higher the passing rate of diabetes-related knowledge in diabetic patients, the lower the compliance rate of fasting blood glucose (OR = 0.47, P <0.05); for patients with non-compliance of fasting blood glucose, diabetes-related knowledge The better, the higher the fasting blood glucose (β = 0.48, P <0.05). Conclusion There is a negative correlation between diabetes-related knowledge and glycemic control in diabetic patients. It may be possible to explain this with long-term illness as a good doctor, that is, because glucose is difficult to control and therefore patients are more likely to acquire diabetes-related knowledge.
