PEREZ UNANUA, Mª. P.; ALONSO SACRISTAN, P.; ROIZ FERNANDEZ, J. C.  y  GARCIA LAZARO, Mª. I.. Type 2 diabetes: What do we expect after changing diagnostic criteria? Increase prevalence of diabetes and earlier diagnosis in a health care center's population. Medifam [online]. 2002, vol.12, n.3, pp.49-60. ISSN 1131-5768.

Objectives: to know the increase of diabetes mellitus (DM) prevalence in our population applying ADA criteria. Secundary objective: a) time to progression to diabetes in patients with glucose =126 mg/dl; and b) differences between glicosilated hemoglobin (HbA₁c) in new and classic diabetics.  Design: retrospective descriptive study.  Material and methods: aleatory sample of clinical histories over 45 years of age, stratified by groups of age and sex. Variations: previous DM diagnosis, two fasting plasme glucose and HbA₁c.  Results: the study included 803 patients, 224 women 60 years, 27.89%, 220 between 45-59 years (27.39%), 162 men 60 years (20.17%) and 197 between 45-59 years (24.53%).The prevalence of DM was 10.08% ± 0.02, additional increase of prevalence with ADA criteria was 4.85% ± 0.015. Prevalence of diabetes, impaired glucose tolerance, impaired fasting glucose was 34.98 % ± 0.03. There were 13 patients with glucose 126 mg/dl, time to progression was 23 months (range 8-48). The mean of HbA₁c close to diagnostic in classic diabetics was 7.41 ± 0.88 and 6.19 ± 0.80 in new diabetics, significant difference p <0.05.  Conclusions: the application of the new ADA criteria increases significantly the prevalence of diabetes and active intervention is needed to reduce risk for developing macrovascular disease. It means harder work.
