Abstract
Background: Uncontrolled type 2 diabetes mellitus (T2DM) is a prevalent issue among older adults. Healthy eating behavior (HEB) is a significant factor contributing to blood sugar control. It is a complex behavior that requires knowledge, attitudes, and skills in food literacy, which can be achieved through collaborative learning by nurses. Although collaborative learning has successfully improved food literacy and HEB among adults and older adults in general, its effectiveness has not been investigated among older adults with uncontrolled T2DM.
Objective: This randomized controlled trial aimed to examine the effects of the Collaborative Learning-Based Food Literacy Enhancement Program (CLFLEP) on HEB and hemoglobin A1c (HbA1c) levels among older adults with uncontrolled T2DM.
Methods: Participants were 80 older adults with uncontrolled T2DM attending primary care units (PCUs) or sub-district health promotion hospitals in northern Thailand. They were randomly assigned to either the experimental group (n = 40) or the control group (n = 40). The experimental group received the CLFLEP to enhance four domains of food literacy through five major elements of collaborative learning, while the control group received standard care. Data were collected between January and June 2023 using the Demographic Data Form, the Eating Behavior Questionnaire, the HbA1c test, and the Short Food Literacy Questionnaire. Data analysis involved descriptive statistics for demographic characteristics and independent t-test and paired sample t-test for HEB and HbA1c based on intention-to-treat (ITT) and per-protocol (PP) analyses.
Results: The experimental group had a higher HEB score than the control group (p <0.001 for ITT and PP) and higher than their scores before program participation (p <0.001 for ITT and PP). The effect size (Cohen's d) was 1.46. The experimental group also had a lower HbA1c level than the control group (p = 0.002 for ITT and PP) and lower than their levels before program participation (p = 0.005 for ITT and 0.001 for PP). The effect size (Cohen's d) was 0.70.
Conclusion: The CLFLEP was effective in promoting food literacy, HEB, and blood sugar control. Nurses can be trained to use this program to provide collaborative health education for older adults with uncontrolled T2DM. Nursing administrators can use these findings to develop organizational policies that enhance nurses' competencies as educators skilled in collaborative learning.
