Manual and Application-Based Carbohydrate Counting and Glycemic Control in Type 1 Diabetes Subjects: A Narrative...

Area of Science:

• Endocrinology
• Metabolic Diseases
• Digital Health

Background:

• Type 1 diabetes (T1DM) is a prevalent chronic condition requiring lifelong insulin therapy.
• Effective glucose management is crucial for preventing long-term complications.
• Carbohydrate counting (CHOC) is a key strategy for mealtime insulin dosing.

Purpose of the Study:

• To review the impact of carbohydrate counting (CHOC) on glucose control, body weight, insulin dosage, and quality of life in T1DM patients.
• To evaluate the effectiveness of CHOC interventions based on available randomized controlled studies.

Main Methods:

• Systematic literature search on PubMed (January 2010 - October 2022).
• Inclusion of randomized controlled studies comparing CHOC intervention with usual care in T1DM subjects.
• Primary outcome measure: glycosylated hemoglobin (HbA1c); secondary outcomes: body weight, insulin dose, quality of life, and hypoglycemia rates.

Main Results:

• CHOC demonstrated a positive effect on glucose control in most studies, especially in adults (5/6 studies).
• Pediatric outcomes were mixed (2/4 studies positive); however, mobile application-based CHOC showed consistent glucose control benefits.
• No significant increase in severe hypoglycemia or weight gain was observed; some studies noted reduced hypoglycemia.

Conclusions:

• Carbohydrate counting (CHOC) offers a viable strategy for enhancing glucose control in T1DM management compared to traditional methods.
• CHOC can be implemented without substantially increasing risks of severe hypoglycemia or weight gain.
• Digital health tools, such as mobile applications, show potential for optimizing CHOC effectiveness in T1DM care.
