Relationship between abdominal fat distribution and diabetes in middle-aged and old people

Objective A analyze the relation between abdominal fat and diabetes mellitus in elderly person aged 51-100. Methods According to the abdominal CT scan in 2015 to 2016 of 162 patients in Peking Union Medical College Hospital, the volume and distribution of their abdominal fat were measured to analyze the relationship between abdominal fat and diabetes mellitus. Results People aged 51-75, no abnormal glucose metabolism group compare with diabetes or fast hyperglycemia group, tend to have less abdominal visceral fat[(63.61±24.95)mm3vs.( 70.39±31.33)mm3t=-1.229, P=0.22], tend to have more abdominal subcutaneous fat[(89.03±32.94)mm3vs. (83.18±43.25)mm3, t=1.070, P=0.43), but both are not significant difference, total abdominal fat is similar between the two group[(152.64±46.84)mm3vs. (151.84±61.32)mm3 , t=0.076, P=0.94], abdominal visceral fat percentage is significantly lower[(41.8±10.9)% vs. (46.9±10.9)%, t=-2.346, P=0.02]. People aged 76-100, no abnormal glucose metabolism group compare with diabetes or fast hyperglycemia group, tend to have more abdominal visceral fat[(68.29±39.58)mm3vs. (51.56±25.89)mm3), abdominal subcutaneous fat[(84.65±41.30)mm3vs. (75.29±42.04)mm3], total abdominal fat[(152.96±69.92)mm3vs. (126.86±62.13)mm3], abdominal visceral fat percentage[(43.7±12)% vs. (41.1±11.8)%], all of them are not significant (t=1.885, 0.839, 1.479, 0.810, respectively; P=0.07, 0.40, 0.15, 0.42, respectively). Conclusions In people aged 51-75, those who had increased ratio of abdominal visceral fat to total abdominal fat were more prone to diabetes or fasting hyperglycemia. In people aged 76-100, no significant correlation was detected between abdominal fat and disorder of glucose metabolism. Key words: Diabetes mellitus, type 2; Obesity; Subcutaneous fat; Viscecal fat
