Survey on the relationship between dietarytherapy compliance of diabetes mellitus patients with pulmonary tuberculosis and glycemic control

Abstract

Objective To investigate the relationship between dietarytherapy compliance of diabetes mellitus patients with pulmonary tuberculosis and glycemic control. Methods According to the three levels(good, medial and bad) of dietary therapy compliance, 136 diabetesmellituspatients with pulmonary tuberculosis were divided into three groups signed by group 1 (good compliance), 2 (medial compliance) and 3 (bad compliance). Questionnaire survey was appliedto respectively investigate the blood glucose level, body mass index, the sputum negative conversion rate and foci absorption rate of the patients in those groups. Results Of the 136 patients, group 1 had 32 (23.5%) patients, while group 2 had 62 (45.6%) patients,group 3 had 42 (30.9%) patients. Among these three groups, the fasting blood glucose (FBG) was(8.36±1.62) mmol/L, the postprandial 2h blood glucose (PBG) was (10.43±1.69) mmol/L, the HbA1c was(8.15±0.99)%, the body mass index (BMI) was (20.46±1.68) kg/m2, the sputum negative conversion rate was 55.9% (76/136), foci absorption rate was 46.3% (63/136). The comparisons of the three groups on FBG(F=34.01,P<0.01), PBG (F=30.77,P<0.01), HbA1c (F=32.35,P<0.01), BMI (F= 16.29,P<0.01),the sputum negative conversion rate(χ2=10.49,P<0.05), foci absorption rate(χ2=7.47,P<0.05) had statistical significance. Thecourse of diabetes (χ2=18.14,P<0.01) and patients' literacy (χ2=21.04,P<0.01) were both influence factors of dietarytherapy compliance. Conclusions Dietarytherapy compliance of diabetes mellitus patients with pulmonary tuberculosis is low and the glycemic control of those patients is poor. The situation of glycemic control and the therapeutic effect, the education about health to patients should be enhanced to make the dietarytherapy compliance better.
