Estudio SIMETAP-DM.

ABSTRACT

INTRODUCTION: The aims of this study were to determine the age- and sex-adjusted prevalence rates of DM, type-1 DM (T1DM), and type-2 DM (T2DM), and to compare the relationship with cardiovascular risk factors, cardiovascular diseases, chronic kidney disease, and metabolic diseases between populations with and without DM. METHODS: SIMETAP-DM is a cross-sectional observational study conducted in a Primary Care setting with a random population-based sample of 10,579 adults. Response rate 66%. The diagnoses of DM, T1DM and T2DM were based on clinical and biochemical criteria and/or the checking of these diagnoses in the medical records. The crude and age- and sex-adjusted (standardised for Spanish population) prevalence rates were calculated. RESULTS: The crude prevalence rates of T1DM, T2DM, and DM were 0.87% (95% confidence interval [95% CI] 0.67-1.13), 14.7% (95% CI 13.9-15.6), and 15.6% (95% CI 14.7-16.5), respectively. The age- and sex-adjusted prevalence rates of T1DM, T2DM, and DM were 1.0% (1.3% for men and 0.7% for women), 11.5% (13.6% for men and 9.7% for women), and 12.5% (14.9% for men and 10.5% for women), respectively. The prevalence of DM in the population≥70 years was double (30.3% [95% CI 28.0-32.7]) that of the population between 40 and 69 years (15.3% [95% CI 14.1-16.5]). Hypertension, peripheral arterial disease, increased waist-to-height ratio, albuminuria, coronary heart disease, atherogenic dyslipidaemia and hypercholesterolaemia were associated with DM. CONCLUSIONS: In a Spanish primary care setting, the age-adjusted prevalences of T1DM, T2DM and DM in the adult population were 1.0, 11.5, and 12.5%, respectively. One-third (33%) of the population over 70 years had DM.
