The effect of mobile application based interactive peer support on glycemic control in patients with type 1 diabetes mellitus / 中华内科杂志

ABSTRACT

Objective@#To evaluate the effect of mobile application (APP) based interactive peer support on glycemic control in patients with type 1 diabetes mellitus (T1DM).@*Methods@#The data of the present study were from the largest mobile APP platform for patients with T1DM in China, Tangtangquan. Patients with T1DM who has registered in the APP for at least 1 year and had completed data entry were recruited. According to the monthly interaction index during the first year of APP registration (including four indicators praise, comment, posting and collection), the eligible patients were divided into the high-interaction group and the low-interaction group. The changes from baseline of self-blood glucose monitoring frequency (SMBG), glycosylated hemoglobin (HbA1c), incidence of hyperglycemia and incidence of hypoglycemia were compared between the two groups after one year of using the APP.@*Results@#A total of 238 patients with T1DM with an age of (27±8) years were included. Among them, 77.3% (184/238) were female. The baseline SMBG [the low-interaction group (1.71±1.14) times/day vs. the high-interaction group (1.82±1.15) times/day] and HbA1c [the low-interaction group (6.72±0.99)% vs. the high-interaction group (6.76±1.04)%] were comparable between the two groups. After one year use of the APP, the frequency of SMBG in the high-interaction group was significantly higher than that in the low-interaction group [ΔSMBG (0.59+2.06) times/d vs. (0.08+1.69) times/d, t=4.280, P=0.04), and the reduction of HbA1c was more obvious in the high-interaction group [ΔHbA1c (-0.40+1.10)% vs. (-0.06+1.13)%, t=5.651, P=0.018] than in the lower-interaction group. The incidence of hyperglycemia in the high-interaction group was significantly lower than that in the low-interaction group [13.19(6.22,23.19)% vs. 17.69(10.56,30.49)%, Z=2.850, P=0.005]. There was no significant difference in the incidence of hypoglycemia between the two groups [4.62(2.14, 8.03)% vs. 4.83(2.06, 8.87)%, Z=1.276, P=0.204]. The correlation analysis showed that interaction index was significantly associated with the reduction of HbA1c and incidence of hyperglycemia.@*Conclusion@#Participation in interactive peer education via mobile APP may be beneficent for glycemic control in patients with T1DM.
