Study on relationship between body weight and waist circumference with prevalence rate of impaired glucose tolerance

  Objective   In order to understand the relationship between body weight, waist circumference(WC), body overweight and obesity with the prevalence rate of IGT, to provide scientific information for IGT prevention and control.

  Methods   Stratified cluster sampling method was applied, and totally 4 682 persons were randomly selected from two communities in urban area and two towns in suburban area.They were all older than 15 and lived there for more than 5 years.They did the questionnaire and accepted physical examination including their body height, weight, and WC.Their two-hour blood glucose after taking 75g oral glucose was also tested.

  Results   The IGT prevalence rate of the older than 15 in the population in Hangzhou communities was 7.43% in males, 6.82% in females, and 7.07% in both sexes respectively.There was a trend that the IGT prevalence rate increased with the increase of body weight.But the IGT prevalence rate in the group with 30kg were higher than 40-60kg group.That present the for mrelation.The IGT prevalence rate of different WC group had a marked difference in statistic.To the WC group of 100 cm attain the high peak.This trend at male and female was consistent.The IGT prevalence rate of body overweight and obesity were significantly higher than that in the group with normal or light weight.OR values were 1.62 and 2.22 respectively.95% CI were 1.50-2.72 and 1.87-4.28 respectively.

  Conclusion   The incidence of IGT is related to body over weight and obesity, especially to abdomen obesity.So remain proper body weight and normal somatotype was very important.In order to prevent the diabetes mellitus occurrence, intervention measures for fat and IGT population should be taken.
