In Spain, according to the Di@bet.es study, 13.8% of the adult population suffers from diabetes and 14.8% from some form of prediabetes (Impaired Glucose Tolerance, Impaired Fasting Glucose or both). Since early detection of prediabetes can facilitate the implementation of therapeutic measures to prevent its progression to diabetes, we believe that preventive strategies in primary care and specialized clinical settings should be agreed. Screening for diabetes and prediabetes using a specific questionnaire (FINDRISC) and/or the measurement of fasting plasma glucose in high risk patients leads to detecting patients at risk of developing diabetes and it is necessary to consider how they should be managed. The intervention in lifestyle can reduce the progression to diabetes and reverse a prediabetic state to normal and is a cost-effective intervention. Some drugs, such as metformin, have also been shown effective in reducing the progression to diabetes but are not superior to non-pharmacological interventions. Finally, an improvement in some cardiovascular risk factors has been observed although there is no strong evidence supporting the effectiveness of screening in terms of morbility and mortality.
The Consensus and Clinical Guidelines Working Group of the Spanish Diabetes Society has issued some recommendations that have been agreed by the Sociedad Española de Endocrinología y Nutrición (SEEN), Sociedad Española de Endocrinología Pediátrica (SEEP), Sociedad Española de Farmacia Familiar y Comunitaria (SEFAC), Sociedad Española de Medicina Familiar y Comunitaria (SEMFYC), Sociedad Española de Médicos Generales (SEMG), Sociedad Española de Médicos de Atención Primaria (SEMERGEN), Sociedad Española de Medicina Interna (SEMI), Asociación de Enfermería Comunitaria (AEC) and Red de Grupos de Estudio de la Diabetes en Atención Primaria (RedGDPS).
