The Effect of Nutrition Education on Glycemic Control in Patients With Type 1 Diabetes

February 16, 2024 updated by: Eva Horová, MD, Charles University, Czech Republic

The Effect of Nutrition Education on Glycemic Control in Patients With Type 1 Diabetes Initiating the Use of Glucose Sensors

The study aims to elucidate whether patients with T1D initiating sensor monitoring experience greater improvement in glycemic control (HbA1c) when provided with structured nutrition education compared to those initiating sensor monitoring without such education.

Study Overview

Status

Completed

Detailed Description

Education on carbohydrate counting and flexible insulin dosing improves glycemic control, which is also enhanced by glucose sensor usage. However, the combined effect of structured education and the initiation of sensor monitoring remains unclear.

Cohorts and Interventions

Group / Cohort
Intervention / Treatment
Group with nutrition education
Patients who experienced at least one structured education session between 24 months before sensor initiation and 6 months after sensor initiation were allocated to the group with education.
Structured nutrition education on carbohydrate counting and flexible insulin dosing by qualified nutritionist.
Group without nutrition education
Patients who received standard care, which may have included short education during routine visits or self-education through online resources or educational materials, were assigned into the group without education.
