Prevalence of impaired glucose regulation in the population of Tianjin

Abstract

To investigate the prevalence of impaired glucose regulation (IGR) in the population of Tianjin. A cross-sectional study was conducted in Tianjin from June to September in 2005. The multi-phasic stratified cluster sampling method was adopted. Totally, 21,454 people were selected as survey sample. Information on risk factors was collected through face-to-face questionnaire interview. Fasting capillary whole blood glucose level and other clinical indexes were tested. The prevalence of impaired fasting glucose (IFG) in the population was 5.61% (5.32% in male, 5.89% in female). The prevalence of impaired glucose tolerance (IGT) was 2.91% (2.59% in male, 3.20% in female) in whole population, and the prevalence of female was significantly higher than that of male (P = 0.04). The prevalences of IFG and IGT increased with the increasing of age. And the prevalences were also influenced by the profession, educational level, and income level. The prevalences of IGT and IFG in Tianjin are similar to those in the other big cities of China.
