Tóm tắt

Pre-diabetes is a term that describes a condition in which a person has higher than normal glucose levels but does not meet the criteria for a diagnosis of diabetes. Clinically, obesity is assessed through anthropometric indices such as BMI, waist circumference (WC), body fat percentage (BFP), and visceral fat (VPF). Objectives: 1. Determine the rate of newly diagnosed pre-diabetic subjects in the community in Quang Binh province; 2. Evaluate of anthropometric indicators in newly diagnosed pre-diabetic subjects. Methods: A descriptive cross-sectional study was conducted on 1206 non-diabetic and pre-diabetic adults (ages range from 20 to 60 years) from Quang Binh province. Results: Prevalence of prediabetic subjects with normal BMI was 46,2%, underweight BMI was 6,2%,  BMI ≥  23 was 47,6% , in which subjects with obesity was 22,5% .The mean waist circumference in pre-diabetic men with central obesity was 81,71 ± 8,08 cm and in pre-diabetic women, the average waist circumference was 76,79 ± 8,48 cm. Prevalence of central obesity in Pre- diabetes group was found 31.3% and 68.7% of people without central obesity (p < 0,05). There was a correlation between HbA1c levels and WC (r=0,101; p < 0,05).The mean of BFP in female prediabetes was higher than male prediabetes  (22,13  ±  5,31%  vs  30,39   ±  4,86 %) .Prevalence of high BFB in prediabetic group was 58,5% , in the normal BFP was 39.8%, and in the low BFP was 1.7%, with (p < 0.001).There was correlation between BFP  with Fasting glucose (r=0,115 ; p< 0,05) and HbA1c (r=0,116; p < 0,05).Mean of visceral fat level  (VFL)   of   prediabetes   was   6,39   ± 3,5 .The high VLF in Pre-diabetic patients was 11.8%,  very  high  VLF  was   3.4%,    and  the normal visceral fat index was 84.8% (p<0.001).respectively, There was no correlation between VFL with Fasting glucose and HbA1c levels. Conclusions: Clinical Usefulness of Waist circumference and body fat percentage (Anthropometric Indices) to Predict the Presence of Prediabetes in Central Vietnam.
