NCT07016958

Brief Summary

This study aimed to evaluate the efficacy of carbohydrate counting in individuals with type 2 diabetes receiving intensive insulin therapy. In addition, the sarcopenia status in this patient group and the effect of carbohydrate counting on sarcopenia were also evaluated.

Outcome Measures

Primary Outcomes (5)

  • HbA1c (%)

    HbA1c levels of the participants were performed in the Biochemistry Laboratory of Fatih Sultan Mehmet Training and Research Hospital. The individuals participating in the study were asked to give blood in the morning after 10-12 hours of fasting after dinner. HbA1c levels were measured by high-performance liquid chromatography (HPLC) method. The statistical analysis of the data obtained from the study was evaluated using the IBM SPSS Statistics (version 22.0) package program.

    Baseline, week 12 and week 24

  • Plasma Glucose Levels

    Plasma glucose levels of the participants were performed in the Biochemistry Laboratory of Fatih Sultan Mehmet Training and Research Hospital. The individuals participating in the study were asked to give blood in the morning after 10-12 hours of fasting after dinner. Plasma glucose levels were analyzed by hexokinase method in colorimetric-spectrophotometric Aeroset (Roche Hitachi cobas 6000) autoanalyzer. The statistical analysis of the data obtained from the study was evaluated using the IBM SPSS Statistics (version 22.0) package program.

    Baseline, week 12 and week 24

  • Muscle Strength

    It was used for the evaluation of sarcopenia. The participants' hand grip strength was measured three times with a digital hand dynamometer (CAMRY-EH101, USA) and the mean value in kg was calculated. The statistical analysis of the data obtained from the study was evaluated using the IBM SPSS Statistics (version 22.0) package program.

    Baseline, week 12, week 24

  • Skeletal muscle mass

    It was used for the evaluation of sarcopenia. Skeletal muscle mass data obtained from the BIA measurement results and skeletal muscle according to the height obtained from this data were calculated by dividing the skeletal muscle mass by the square of the height.The statistical analysis of the data obtained from the study was evaluated using the IBM SPSS Statistics (version 22.0) package program.

    Baseline, week 12, week 24

  • Physical performance

    It was used for the evaluation of sarcopenia. In the timed walk-up test, the patient is asked to get up from the chair, walk at a normal walking speed on a flat surface of 3 meters, turn around, walk back and sit back in the chair. The time between the patient getting up from the chair, walking and sitting down again is recorded and the patient's dynamic balance during walking is also evaluated. The statistical analysis of the data obtained from the study was evaluated using the IBM SPSS Statistics (version 22.0) package program.

    Baseline, week 12 and week 24

Secondary Outcomes (15)

  • Blood lipid levels

    Baseline, week 12 and week 24

  • Hypoglicemia Period

    Baseline, week 12 and week 24

  • Total Insulin Dose

    Baseline, week 12 and week 24

  • Daily Prandial Insulin

    Baseline, week 12 and week 24

  • Daily Basal Insulin

    Baseline, week 12 and week 24

  • +10 more secondary outcomes

Study Arms (2)

Training Group

EXPERIMENTAL

The training group received advanced carbohydrate counting training in addition to standard medical and medical nutrition therapy.

Behavioral: Carbohydrate Counting Training

Control Group

NO INTERVENTION

The control group continued standard medical and medical nutrition therapy only.

Interventions

Advanced Carbohydrate Counting Training is a meal planning training where individuals can calculate the amount of carbohydrates in foods based on their portion sizes, and the insulin doses they need to take based on their plasma glucose levels and the amount of carbohydrates they consume.
