[Clinical characteristics and classification of 2128 outpatients with diabetes].
OBJECTIVE
To determine the clinical characteristics of diabetic outpatients and their classification,and to provide some suggestions for diagnostics, education and follow-up of outpatients.


METHODS
We analyzed the data of 2 128 outpatients recorded in the past year, and studied the clinical characteristics, distribution of types and relation between glutamate decarboxylase antibody (GADA) and age, sex and duration.


RESULTS
Of all the patients, 918 (43.1%) were new-onset, and 1883 (88.6%) aged 40 or older. Altogether 782(36.7%) of the patients were done with GADA examination and 4.2% of them were GADA positive. Twelve patients were type 1 diabetes and 764 were type 2 diabetes, respectively with 33.3% and 3.8% GADA positive. The prevalence of GADA positive was 5.1% for men and 3.2% for women (P > 0.05). The frequencies of GADA positive in patients with different duration (1 year, 5 years, 10 years and more) were 4.4%, 4.8%, 1.7% and 4.9% (P >0.05) respectively.


CONCLUSIONS
The new-onset population of the studied patients is dominated by 40-year olds or older. Type 2 diabetes is the main type in the diabetes spectrum. The frequency of GADA positive is irrelevant to sex and duration.
