Diabetes Mellitus: Type 2 and Gestational

4.3K
Type 2 diabetes, characterized by insulin resistance, arises when the insulin receptors on cells lose responsiveness to insulin, diminishing the cell's capacity to take up glucose, resulting in elevated blood glucose levels. To receive a diagnosis of Type 2 diabetes, a series of blood glucose tests are necessary to assess whether the blood glucose falls within normal parameters. If the result is out of the normal range, a patient may be diagnosed as prediabetic or diabetic, depending on the...

Inflammatory Bowel Disease III: Diagnostic Studies and Management I-Nutritional Therapy

631
Various diagnostic tests are employed in the diagnostic process for Inflammatory Bowel Disease (IBD), particularly to differentiate between Crohn's disease and ulcerative colitis.
Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...

Area of Science:

  • Digital health interventions
  • Gestational diabetes mellitus (GDM) management
  • Medical nutrition therapy

Background:

  • Traditional paper-based dietary tracking for GDM presents challenges.
  • The M♡THer app, a digital platform for GDM, was updated with a diet diary feature based on user feedback.
  • Digital tools offer potential solutions for improving GDM care.

Purpose of the Study:

  • To evaluate the uptake, usage, usability, and acceptability of a new digital diet diary feature within the M♡THer app.
  • To assess the impact of the digital diet diary on patient-provider communication and dietary literacy.
  • To identify barriers and facilitators for the adoption and effective use of the digital diet diary.

Main Methods:

  • The digital diet diary was co-designed and trialled across three hospital services.
  • Data collection involved user engagement metrics, surveys, and interviews with healthcare providers and app users over six months.
  • Thematic analysis and triangulation were used to analyze qualitative and quantitative data.

Main Results:

  • Uptake of the diet diary varied from 13% to 53% among 305 M♡THer app users, with 95 users actively engaging.
  • Users logged dietary intake for an average of 33.5 days, reporting improved patient-provider communication, reduced consultation times, and enhanced dietary literacy.
  • Key barriers to uptake included the timing of introduction and usability challenges, while optimal engagement was affected by these factors.

Conclusions:

  • A digitally supported diet diary integrated into the M♡THer app is feasible and beneficial for GDM management.
  • The digital diary enhances diet tracking and consultation efficiency, supporting both patients and healthcare providers.
  • Future improvements should focus on earlier introduction, a streamlined user interface, and an expanded food database for optimal effectiveness.
