Effects of health check-up feedback style (HCFS) on blood glucose and weight in type 2 diabetes patients aged 75 years and older: a randomized controlled study

Objective To analyze the effect of health check-up feedback style (HCFS) on the blood glucose level and weight of type 2 diabetes patients aged 75 years and older. Methods 120 consecutive patients with type 2 diabetes and aged 75 and older who were taking annual health check-up and receiving paper-based medical examination reports at Peking Union Medical College Hospital were enrolled into this study. The patients were randomly divided into two groups (control group and study group). All patients received annual health check-up between November 2014 and October 2015 (baseline health check-up). Patients in control group were given paper-based feedback as usual, while those in study group received feedback via face-to-face or telephone conversations. All patients received their second annual health check-up between November 2015 and October 2016. The patients' blood glucose and weight at the second health check-up were compared between the two groups. Results In baseline health check-up, the levels of HbA1c and BMI showed no difference between the two groups. In the second health check-up, HbA1c and BMI of study group were lower than control group[(7.17±0.58)% vs. (7.44±0.72)%, P=0.027; (24.3±3.8)kg/m2vs. (25.0±4.2)kg/m2,P=0.049]. Fast blood glucose and waist circumference showed no difference between the two groups. Conclusions Combination of paper-based reports and face-to-face or telephone conversations to feedback on health check-up results led to better blood glucose and BMI control in old aged type 2 diabetes patients. HCFS is of vital importance. Key words: Diabetes mellitus, type 2; Blood glucose; Body weight; Health check-up
