Evaluation of a Structured Nutrition Educational Program Among Patients With Type 2 Diabetes
sunnuntai 17. toukokuuta 2026 päivittänyt: Ly Na Dau, Cho Ray Hospital
Evaluation of a Structured Nutrition Education Program for Patients With Type 2 Diabetes Who Have Not Achieved Glycemic Goals Under Oral Anti-diabetic Medications or in Combination With Basal Insulin in Vietnam
The purpose of this study is to find out if learning about healthy eating can help people with diabetes control their blood sugar better.
This study is for men and women between 16 and 70 years old who currently use only oral-diabetic medications or in combination with basal insulin but their glycemia have not been in the target range.
The investigators want to answer the following questions:
Can nutrition education help lower HbA1c (a blood test that shows average blood sugar over the past 3 months)? Can it improve nutrition related knowledge, attitude and behaviors among patients with type 2 diabetes? Will it help reduce fasting blood sugar, lipid levels, body weight, and the number of times low blood sugar (hypoglycemia) happens?
Participants will be divided into two groups:
One group will receive a nutrition booklet. The other group will receive the same booklet and join four monthly lessons with a researcher.
The four lessons will talk about:
Goals for managing diabetes Main nutrients in food and their effects on glycemia How to plan meals How to eat in a way that supports better blood sugar control

Yksityiskohtainen kuvaus
This study will involve 253 people with diabetes who currently uses only oral anti-diabetic medications or in combination with basal insulin without their glycemia within the target range.
The study will take place at Cho Ray Hospital in Ho Chi Minh City, Vietnam, and will run from 2026 to 2027. People will be invited to join at the Endocrinology Consultation Unit. If they agree, their phone number will be collected and the research team will call them later to explain more about the study. If they are still interested, a meeting with the researcher will be planned on the day of their next consultation. During this meeting, the patients will be screened for their eligibility.
On the screening day, the patients will have their blood tests to check their sugar, HbA1c, cholesterol, and kidney function as part of their routine visit and have a usual consultation with their doctor. If the patients meet all the criteria and agree to take part in, the patients will sign the consent form and take short tests on nutrition related knowledge, attitude, and behavior questionnaire designed and evaluated by the researcher.
After that, the patients will be randomly assigned to one of two groups. One group will get a nutrition booklet only. The other group will receive the booklet plus attend four monthly sessions with a researcher to learn about healthy eating for diabetes.
During the 6-month study period, all participants will have blood tests every 3 months to check HbA1c, fasting sugar, and lipid; the participants will be asked monthly about any low blood sugar episodes; their weight and waist size will be measured every 3 months, and their height will be measured at the start of the study. The participants will be interviewed with the nutrition related knowledge-attitude-behavior questionnaire again after 6 months.

Interventio / Hoito |
|---|---|
|
Ei väliintuloa: Standard group
The participants of this group will be given a nutrition booklet and follow the standard of care, which means the participants routinely have about 5 to 10-minute consultations with their doctors.
During this time, the participants tell their doctors about how they feel physically, their doctors then examine the patients, educate them if necessary, and prescribe the tests and medications.

Kokeellinen: Nutrition Intervention group
Participants in the intervention group will attend a structured nutrition education program consisting of four monthly sessions, each lasting approximately 40 to 60 minutes.
These sessions will be conducted in small groups by the researcher.
Each session includes: A 20-minute presentation delivered by the researcher using visual aids, such as slides and educational images, a 15-minute Q and A section, and 20 minutes of working on group assignments.
Session Topics: Treatment Goals in Diabetes Care: Overview of blood glucose targets and the importance of achieving glycemic control.
Key Nutritional Components of Food: Roles of carbohydrates, proteins, fats, fiber, and their impact on blood glucose.
Principles of Meal Planning: Adjusting energy intake based on physical activity levels and BMI.
Understanding the Food Exchange System: Introduction to food exchange lists; selecting the appropriate number of food exchanges.
