[ADA-97 criteria, prevalence of diabetes mellitus and the most southern counties of Catalonia].
OBJECTIVE
To find the prevalence of diabetes mellitus (DM) and disturbed basal glucaemia in the population over 24 years old and the relationship of this to factors of risk of becoming diabetic.


METHODS
Descriptive, cross-sectional population study.


METHODS
Community, county (Baix Ebre-Montsià-Terra Alta) and primary care (9 health districts) context.


METHODS
Inhabitants of the three most southerly counties of Catalonia over 24 years old (106,551 out of 132,938).


METHODS
We randomised from the data base of the computer service of the Catalan Institute of Health (100% coverage), for an estimated prevalence of 15%, losses of 20%, 95% CI and +/- 5% accuracy, a sample of 245 people (we studied 198). We informed each doctor of his/her patients in the study. If the patient was diabetic, his/her doctor filled out a questionnaire; if not, the doctor also requested from the laboratory two glucaemia analyses taken after fasting.


RESULTS
Using the diagnostic criteria and screening methods of the ADA-1997, we obtained the following results: 1. 14.1% prevalence of DM (1.5% new diagnoses); 4% prevalence of disturbed basal glucaemia. 2. Likelihood of diabetes: age > 45 (4.7 times greater); triglyceridaemia > 250 mg/dl (4.5 times greater); BMI > 27 (2.9 times).


CONCLUSIONS
High prevalence of DM, with high proportion known through primary care. We know the prevalence of disturbed basal glucaemia. DM-related risk factors in our population were: age > 45, BMI > 27 and hyper-triglyceridaemia. Our primary care focus can better manage the resources dedicated to DM.
