About this study
Official title: Effects of Basic Carbohydrate Counting Versus Standard Outpatient Nutritional Education: A Randomized Controlled Trial Focusing on HbA1c and Glucose Variability in Patients With Type 2 Diabetes (The BCC Study)
The aim of the study is to examine the health benefits of adding a concept in basic carbohydrate counting (BCC) to the routine outpatient nutritional education for adult patients with type 2 diabetes.
The study hypothesis is that training and education in the BCC concept will improve glycaemic control either by reducing HbA1c or the average plasma glucose variability more than offering the routine dietary care as a stand-alone dietary treatment.
Read the detailed description
The trial has a parallel-group design with a study duration of 48 weeks for each participant (a 6-month intervention period and a 6-month follow-up period). A total of 226 patients will be enrolled in the trial. Participants will be randomized to one of two arms: 1) Standard medical and dietary care (control group) or 2) Structured training and education in the BCC concept in addition to standard medical and dietary care.
The primary objective is to evaluate the six months effect of structured training and education in the BCC concept compared to standard dietary care on glycaemic control as assessed by HbA1c or MAGE (mean amplitude of glycaemic excursions).

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Standard nutritional educationBehavioural
Also called Routine dietary care in type 2 diabetes
Routine dietary care consists of three individual consultations with a trained dietitian. The individual guidance will be in accordance with the dietary guidelines in type 2 diabetes.
Basic carbohydrate countingBehavioural
Also called Education in BCC in addition to standard dietary care
The BCC concept is a group-based program consisting of three group sessions delivered by trained dietitians.
| Study group | Role | What they receive |
|---|---|---|
| Standard nutritional education | Active comparator | Control group Receives: Behavioral: Standard nutritional education |
| BCC | Experimental | Education and training i basic carbohydrate counting (BCC) plus standard nutritional education Receives: Behavioral: Basic carbohydrate counting |

Questions about this trial
What is this clinical trial studying?
A study testing Standard nutritional education and Basic carbohydrate counting in people with Type2 Diabetes and Diabetes Mellitus, Type 2, run by Steno Diabetes Center Copenhagen at 1 site in Denmark.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 5 inclusion and 11 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 27 Apr 2023. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Denmark. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change in HbA1c (time frame: Baseline, 6 months). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03623139, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 27 Apr 2023.
