Diabetes mellitus presents a high prevalence and morbimortality. The aim of the present study was to know the number of newly diagnosed diabetic patients in addition to those who present abnormal glucose tolerance and possible presence of associated risk factors.


This study was carried out in Lejona (Vizcaya) from 1984-1985. The prevalence of non insulin-dependent diabetes mellitus (NIDDM) and abnormal glucose tolerance (AGT) in people older than or equal to 30 years of age by a randomized sample stratified by pyramids of age and sex (n = 862). The following data were collected: age, sex, height, weight, medications taken, family and personal history of diabetes mellitus (DM) and blood pressure. A glycemia curve was made following the criteria recommended by the Committee of Experts of the World Health Organization (WHO).


The prevalence of DM observed in the sample was of 6.4% (confidence interval of 95%: 4.75-8.01%) of which 3.6% corresponded to unknown DM and 2.8% to known DM. The prevalence of AGT was 10.4% (confidence interval 95%: 8.40-12.48%). Greater association was observed between DM and obesity, lower height, high blood pressure and age over 50.


More than half of the diabetics were unaware of the disease. Given the association of non insulin-dependent diabetes mellitus with modifiable factors (obesity, high blood pressure) control of risk factors would be useful with the aim of decreasing the prevalence of diabetes mellitus and avoid the associated chronic complications of the disease.
