To discuss the correlations between the distribution of constitutional types of Traditional Chinese Medicine（TCM） and the microalbuminuria index in patients with impaired glucose regulation (IGR).Methods: 224 patients with IGR and 60 cases of normal blood glucose were randomly selected, Constitutional types of two groups were distinguished used the Chinese Medical constitution questionnaires, Determined Urinary albumin levels, and analyzed the correlation of IGR various constitutional types and microalbuminuria. Results: In 224 cases of IGR, there were 8 cases of gentleness type (3.6%), 42 cases of qi-deficiency type (18.6%), 4 cases of yang-deficiency type (1.8%), 38 cases of yin-deficiency type (17.0%), 60 cases of phlegmatic hygrosis type (26.8%), 28 cases of dampness heat type (12.5%), 34 cases of stasis type (15.2%), 10 cases of qi-depression type (4.5%), none particular type. The prevalence of MAU in stasis and phlegmatic hygrosis types was higher than qi-deficiency, yin- deficiency and dampness heat types（P<0.01）. Conclusion:The main constitutional types of IGR were phlegmatic hygrosis type, qi-deficiency type, yin-deficiency type, dampness heat type and stasis type. The prevalence of MAU of stasis type and phlegmatic hygrosis type was significantly higher, and indicated a higher risk of vascular disease.
