EFFECTIVENESS OF A TRIPLE NUTRITIONAL INTERVENTION AND PHYSICAL IN PREDIABETIC PATIENRS

Diabetes represents a substantial burden on health care systems. People with prediabetes IGT (impaired glucose tolerance) or IFG (impaired fasting glucose) are at high risk of developing diabetes, and up to 50% progress to diabetes within 5 years.

OBJECTIVE: To evaluate the effectiveness of a triple intervention (physical activity and ordered healthy diet) to improve glycosylated hemoglobin control in prediabetic patients.

MATERIAL AND METHODOLOGY: Randomized, open, controlled clinical trial with routine clinical practice (health advice for physical activity and healthy diet). Study population: obese or overweight patients of the OSI Araba aged 35-70 years who are in the contemplation stage.

Response assessment: Primary variable: glycosylated hemoglobin; Secondary variables: Body Mass Index (BMI) (kg/cm2); blood pressure (mm Hg); satisfaction questionnaire score; physical exercise index (IPAQ) (METs). Statistical analysis: The analysis of the main variable (change in HbA1c at 6 months between both groups) will be assessed by analysis of covariance, ANCOVA, adjusting for baseline HbA1c. Sample size: 41 patients per arm (+30% to cover losses to follow-up).
