Interdisciplinary and Family Intervention to Prevent Type 2 Diabetes

Efficacy of a Family and Interdisciplinary Intervention to Prevent Diabetes, and Effect on Family Profiles of Insulin Secretion and Insulin Resistance in Patients With Prediabetes

The purpose of the study is to evaluate the effect of a family and interdisciplinary approach on individual and family insulin resistance and insulin secretion in patients with prediabetes.

This a randomized clinical trial designed to evaluate the efficacy of the following treatments:

1. Family and interdisciplinary approach that includes nutritional, physical activity and psychological counseling + metformin 850mg twice at day for 12 months
2. Individual approach that includes nutritional and physical activity counseling + metformin 850mg twice at day for 12 months

To improve individual and family insulin resistance and insulin secretion in patients with prediabetes.

Patients will have a follow-up visit every month in the Metabolic Research Laboratory at the University of Guanajuato, Mexico, and will have a fasting measurement of lipids, glucose and insulin every 3 months, as well as 2h oral glucose tolerance test (OGTT) at basal, 6 and 12 months.

Inclusion Criteria:

• Patients with prediabetes (Fasting glucose 100-125mg/dl and/or 2h post OGTT glucose 140-199mg/dl)
• Family of patients with prediabetes (in case of the patients that are randomized to FAMILY APPROACH)
• Signing of the inform consent

Exclusion Criteria:

• Type 2 diabetes
• Pregnancy
• Liver disease
