Abstract: Objective To investigate the relationship between body fat percentage (BFP)and blood glucose fluctuation in the elderly patients with type 2 diabetes mellitus(T2DM). Methods The levels of BFP and blood glucose of 188 elderly patients with T2DM were collected, and the blood glucose standard deviation(SDBG) was used to reflect blood glucose fluctuation. According to the level of SDBG,all the patients were divided into great blood glucose fluctuation group(SDBG≥2 mmol/L) and small blood glucose fluctuation group(SDBG<2 mmol/L). The levels of waist circumference, hip circumference, waist-to-hip ratio and BFP in the two groups were observed and compared.The relationship between SDBG and above indexes was analyzed. Results Compared to small blood glucose fluctuation group,the course of disease was significantly longer, and the waist circumference, hip circumference,waist-to-hip ratio,BFP were significantly lower in the great blood glucose fluctuation group(P<0.05). SDBG was negatively correlated with waist circumference,hip circumference,waist-to-hip ratio and BFP(r=-0.225,-0.162,-0.166,-0.232,respectively,all P<0.05). Binary Logistic regression analysis showed that BFP was the influencing factor of blood glucose fluctuation after adjusting course of disease, waist-to-hip ratio(OR=0.946, 95%CI: 0.903-0.991, P=0.020). Conclusions There is a negative correlation between BFP and blood glucose fluctuation in the elderly patients with T2DM. It is important to maintain reasonable BFP in the elderly patients with T2DM.
