2015年宁波市江东区65岁以下2型糖尿病患者空腹血糖控制情况及其影响因素分析

目的 分析宁波市2型糖尿病患者空腹血糖及其控制情况的影响因素,为糖尿病的社区防控提供依据。 方法 2015年12月从宁波市江东区5个街道招募600名2型糖尿病患者,进行集中问卷调查、体格检查和实验室检测,采用linear线性回归对空腹血糖的影响因素进行分析,采用logistic回归对空腹血糖控制情况的相关因素进行分析。 结果 本次调查检测600名2型糖尿病患者,平均空腹血糖为(6.94±2.25)mmol/L,空腹血糖控制良好的患者有345人(57.50%)。Linear一元线性回归分析显示空腹血糖与腰围、舒张压、吸烟、糖尿病病程及高脂饮食呈正相关(P<0.05),与行为转变阶段、按照糖尿病要求饮食、运动及饮食信心2(与非糖尿病患者共同进食坚持按要求进食信心)呈负相关(P<0.05)。Linear多元线性回归分析显示空腹血糖与腰围(标化回归系数β=0.113,P=0.007)、舒张压(β=0.096,P=0.023)、糖尿病病程(β=0.087,P=0.030)呈正相关,与行为转变阶段(β=- 0.111,P=0.006)呈负相关。单因素logistic回归分析显示按照糖尿病饮食要求进食、饮食信心2得分高、运动多能够提高空腹血糖控制率(P<0.05);而腰围大、糖尿病病程长会降低空腹血糖控制率(P<0.05)。多因素logistic回归分析显示糖尿病病程长(OR=0.90, 95%CI:0.81~0.99)会降低空腹血糖控制率,按照糖尿病饮食要求进食(OR=1.46, 95%CI:1.12~1.88)能够提高空腹血糖控制率。 结论 本次研究2型糖尿病患者空腹血糖控制良好,空腹血糖及其控制率的危险因素是病程、腰围及舒张压,保护因素是按照糖尿病要求进食、适度运动及较高的行为转变阶段。

Status of fasting blood glucose control and its influencing factors among type 2 diabetic patients aged 65 years and below in Jiangdong District of Ningbo City, 2015

Objective To analyze the level of fasting blood glucose (FBG) and the factors influencing its control status among urban patients with type 2 diabetes mellitus so as to for provide a basis for diabetes mellitus prevention and control in communities. Methods A questionnaire survey, physical examination and laboratory testing were conducted in 600 type 2 diabetic patients enrolled from 5 streets of Jiangdong District, Ningbo City in December 2015. Linear regression analysis and logistic regression analysis were respectively used to analyze the factors influencing FBG and FBG control. Results Six hundred type 2 diabetic patients were surveyed in this study. The average FBG was (6.94±2.25) mmol/L, and 345 (57.50%) diabetic patients’ FBG was controlled well. Unitary linear regression analysis showed that FBG was positively correlated with waist circumference, diastolic pressure, smoking, duration of diabetes and high fat diet (P<0.05), but negatively correlated with behavior changing phase, diet habit based on guidance of diabetes, physical exercise and diet confidence II (the confidence with correct diet when dieting with others without diabetes) (P<0.05). Multiple linear regression analysis showed that FBG was positively correlated with waist circumference (standardized coefficient β=0.113, P=0.007), diastolic pressure (β=0.096,P=0.023) and duration of diabetes (β=0.087, P=0.030), but negatively correlated with behavior changing phase (β=-0.111, P=0.006). Single factor logistic regression analysis showed that diet habit based on guidance of diabetes, high score of diet confidence II and adequate duration of physical exercise could improve FBG control rate (P<0.05), while bigger waist circumference and longer duration of diabetes could worsen FBG control status. Multiple factor logistic regression analysis showed that longer duration of diabetes (OR=0.90, 95%CI:0.81-0.99) could reduce FBG control rate, whereas diet habit based on guidance of diabetes (OR=1.46, 95%CI:1.12-1.88) could increase FBG control rate. Conclusions FBG control status of the patients with type 2 diabetes mellitus surveyed in this study is satisfactory. The risk factors of FBG and FBG control rate are duration of diabetes, waist circumference and diastolic pressure, while the protective factors include diet habit based on guidance of diabetes, adequate duration of physical exercise and high behavior changing phase.
