Prevalence of impaired glucose regulation in the population of Tianjin.

Objective: To investigate the prevalence of impaired glucose regulation (IGR) in the population of Tianjin.

Methods: 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.

Results: 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.

Conclusion: The prevalences of IGT and IFG in Tianjin are similar to those in the other big cities of China.
