[A survey of diabetes mellitus among inpatients in Guangdong province].
OBJECTIVE
To investigate the prevalence of diabetes and impaired glucose regulation (IGR) among the inpatients and their clinical features.


METHODS
A cross-sectional survey was conducted among the inpatients registered in ten university hospitals of Guangdong, China during the week before the Diabetes Day of 2004. The fasting plasma glucose (FPG) levels of first screen when the patients were hospitalized were recorded. Those with the FPG levels from 5.6 to 6.9 mmol/l. who had not been previously diagnosed as with diabetes (P-DM) underwent oral glucose tolerance test (OGTT). The patients were classified into 5 groups according to the OGTT results: normal glucose tolerance (NGT), DM, impaired glucose tolerance (IGT), impaired fasting glucose (IFG), and IGT accompanied with IFG, the last 3 groups being called by a joint name of impaired glucose regulation (IGR). Those with FPG >or= 7.0 mmol/L who had not been diagnosed as with DM previously were diagnosed as newly-diagnosed DM (New-DM).


RESULTS
Of the 8753 inpatients investigated 8.3% were with P-DM, 6.8% were diagnosed as with New-DM, and 4.9% were with IGR. OGTT was carried out in 433 inpatients. 27.9% of which were classified as with New-DM, and 49.9% with IGR. In the New-DM patients, 41.8% were accompanied with hypertension, 43.2% with proteinuria, and 67.6% with dyslipidemia.


CONCLUSIONS
The prevalence rates of diabetes and IGR were 15.1% and 4.9% respectively among the inpatients investigated. The rate of diabetes was 27.9% among the patients underwent OGTT. Proteinuria, dyslipidemia, and hypertension were the concomitant disorders frequently found in New-DM.
