Type 1 Diabetes
Conditions
Brief summary
Carbohydrates are the nutrient in the diet with the greatest impact on blood glucose. Inadequate carbohydrate counts are associated with higher A1c and greater variations in postprandial blood glucose. Clinical guidelines for the nutritional treatment of diabetes recommend that patients with DM1 learn carbohydrate counting or some similar systematic strategy that allows for better metabolic control. However, despite the recommendations, this is still not a reality for most healthcare services treating individuals diagnosed with DM1.
Detailed description
The study aims to assess the impact of a structured nutrition education programme for nutritional education and carbohydrate counting, in group sessions, on glycemic control and nutritional literacy in people with DM1. This will be achieved by evaluating the glycaemic control through A1c and daily glycaemic variability (time on target, mean glycaemia), as well as the level of knowledge before and after the intervention.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Differences between baseline A1c (%) and 90 days after the last educational session. | 90 days | The outcome will be assessed through blood exams |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Difference in the level of nutritional knowledge assessed through a questionnaire "Nutrition knowledge" collected at baseline and in the last educational session (scale 0 to 23, where 23 is the highest). | 90 days | The level of knowledge will be measure in a likert scale from 0 (minimum) to 23 (maximum), where a higher score is better than a lower one |
| Difference in time in range (%) between baseline and 90 days following the last educational session | 90 days | The outcome will be assessed through data from participants' continuous glucose monitoring system |
| Difference in the glucose coefficient of variation (%) between baseline and 90 days following the last educational session | 90 days | The outcome will be assessed through data from participants' continuous glucose monitoring system |
| Difference in mean glycaemia (mg /dL) between baseline and 90 days following the last educational session | 90 days | The outcome will be assessed through data from participants' continuous glucose monitoring system |
