Summary
Digital storytelling interventions show promise for improving glycemic control in Hispanic adults with type 2 diabetes (T2D). This culturally tailored approach was found to be acceptable and feasible for enhancing diabetes self-management.
Area of Science:
- Health disparities
- Digital health interventions
- Diabetes self-management
Background:
- Hispanic adults with type 2 diabetes (T2D) face higher complication and mortality rates.
- Existing research on digital storytelling for T2D outcomes in this population is limited.
- Digital storytelling interventions leverage community-based participatory research to amplify patient voices.
Purpose of the Study:
- To evaluate the impact of a digital storytelling intervention on glycemic control in Hispanic patients with T2D.
- To assess the acceptability and narrative quality of the intervention among participants.
Main Methods:
- A multicenter, randomized clinical trial was conducted with Hispanic adults with poorly controlled T2D (hemoglobin A1c ≥8%).
- The intervention group viewed a 12-minute digital storytelling video in Spanish, focusing on diabetes self-management behaviors.
- The control group received culturally tailored printed educational materials.
Main Results:
- A modest, statistically significant improvement in hemoglobin A1c levels was observed in the intervention group compared to the control group (adjusted analysis, P=.04).
- The digital storytelling intervention demonstrated high acceptability and narrative quality.
- Participant retention was high at 86% after 3 months.
Conclusions:
- A digital storytelling intervention, co-developed with and for Hispanic adults with T2D, is acceptable and feasible in primary care.
- The intervention led to a modest improvement in glycemic control, suggesting potential for integration into diabetes self-management programs.
- This scalable intervention may help address health inequities in T2D management for Hispanic adults.

The therapy for diabetes aims to alleviate hyperglycemia-related symptoms, prevent acute metabolic decompensation, and reduce chronic end-organ complications. Glycemic control is evaluated through short-term (self-monitoring, continuous glucose monitoring) and long-term (A1c, fructosamine) metrics, enabling near real-time tracking of blood glucose levels and reflecting glycemic control over specific time frames.

Diabetes mellitus is a chronic metabolic disorder characterized by high blood glucose levels due to inadequate insulin production, insulin resistance, or both. The condition affects millions worldwide and can significantly impact their health and quality of life.
Type 1 diabetes is an autoimmune disease in which the immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. As a result, the body is unable to produce sufficient insulin, and individuals with...

2.3K
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...

For most patients, experiencing several weeks of polyuria, polydipsia, fatigue, and significant weight loss may indicate the presence of diabetes. Furthermore, adults displaying the phenotypic appearance of type 2 diabetes (particularly those who are obese and not initially insulin-requiring), may have islet cell autoantibodies, suggesting autoimmune-mediated β cell destruction and a diagnosis of latent autoimmune diabetes of adults (LADA). The categorization of glucose homeostasis is...

Carbohydrates are polymers composed of molecules containing atoms of carbon, hydrogen and oxygen. One gram of carbohydrate can provide four kilo-calories of energy, which makes it the most efficient instant energy source.
Starch accounts for approximately 60% of the carbohydrates consumed by humans. Since amylase enzymes cannot function in the stomach's acidic environment, starch can only be digested in the mouth and small intestine. Simple sugars are found naturally in milk and fruits in...
