Medical Nutrition Therapy, In-Person, or Telephone Group Lifestyle Intervention for Type 2 Diabetes? A Qualitative Study of Patient Perceptions and Treatment Preferences.

Purpose: The purpose of the study was to explore the thoughts, feelings, motivations, and assignment preferences of community health center patients with type 2 diabetes considering participation in a 2-year lifestyle intervention trial aimed at weight loss and increased physical activity. The reasons for patients' delivery mode preferences were also explored to aid in the design of future interventions for controlled trials.

Methods: Using structured telephone interview guides, 57 patients with type 2 diabetes receiving primary care at 3 community health centers affiliated with an academic medical center were interviewed regarding the perceived pros and cons of each of the 3 possible treatment assignments: telephone conference group, in-person group, or individual medical nutrition therapy.

Glycaemic variability, assessed with continuous glucose monitors, is associated with diet, lifestyle and health in people without diabetes.

Background: Continuous glucose monitors (CGMs) provide high-frequency information regarding daily glucose variation and are recognised as effective for improving glycaemic control in individuals living with diabetes. Despite increased use in individuals with non-diabetic blood glucose concentrations (euglycemia), their utility as a health tool in this population remains unclear.

Objectives: To characterise variation in time in range (TIR) and glycaemic variability in large populations without diabetes or impaired glucose tolerance; describe associations between CGM-derived glycaemic metrics and metabolic and cardiometabolic health traits; identify key diet and lifestyle factors associated with TIR and glycaemic variability.
