Aims To estimate the prevalence and the determinants of diabetes mellitus and impaired glucose regulation (IGR) in an adult Canarian population.
Methods Cross-sectional study. One thousand and thirty subjects aged 30–82 years were randomly selected. Participants completed a survey questionnaire and underwent blood pressure measurements, anthropometry, blood samples, and a 75-g standardized oral glucose tolerance test.
Results The age-standardized prevalence of diabetes was 15.8% (95% confidence interval: 11.8–19.8) in men and 10.6% (7.1–14.1) in women. Total prevalence was 13.2% (11.1–15.2). Among individuals with diabetes, 55.4% of men and 38.2% of women were not previously diagnosed. The age-standardized prevalences of impaired glucose tolerance and impaired fasting glycaemia were 11.4% (9.5–13.4) and 2.8% (1.8–3.8), respectively. In multivariate analyses, age, waist circumference, serum triglycerides, and familial history of diabetes were independently associated with diabetes in both sexes, while a value of C-reactive protein (CRP) ≥ 1 mg/l showed an association with diabetes, but only in men. Age and triglycerides were related to impaired glucose regulation (IGR) in both sexes, waist circumference was related to IGR exclusively in men, and familial diabetes exclusively in women. Statistically significant interactions between gender and both CRP and triglycerides were found with respect to diabetes, and between gender and both waist circumference and triglycerides for IGR.
Conclusions Compared with the rest of Spain, the prevalence of diabetes is moderately increased in this area of the Canary Islands. Along with other well-established risk factors, CRP was independently associated with diabetes, but only in the male population.
