The Effect of Nutrition Literacy Promotion Program with LINE Application on the Food Consumption Behaviors Among Village Health Volunteers
Keywords:
Nutrition literacy, Food consumption behaviors, Village health volunteers, LINE applicationAbstract
This quasi-experimental research employed a two-group pretest–posttest design to examine the effectiveness of a nutrition literacy enhancement program delivered via the LINE application on the dietary consumption behaviors of village health volunteers. The sample consisted of 66 village health volunteers, selected through purposive sampling and equally assigned into an experimental group (n = 33) and a comparison group (n = 33). The experimental group participated in a 4-week nutrition literacy program via the LINE application, while the comparison group received conventional health education. The intervention tool was the nutrition literacy enhancement program delivered through the LINE application. Data were collected using a dietary consumption behavior questionnaire, which demonstrated a content validity index of 0.94 and a Cronbach’s alpha coefficient of 0.78. Data were analyzed using descriptive statistics and t-tests. The results revealed that the experimental group had significantly higher mean dietary consumption behavior scores after the intervention compared to before the intervention (p < .05), and also significantly higher than those of the comparison group (p < .05). These findings indicate that the nutrition literacy enhancement program via the LINE application effectively improved dietary consumption behaviors among village health volunteers. The effectiveness of the program may be attributed to its ability to enhance nutrition literacy, build self-confidence, and utilize technology to support continuous learning, thereby facilitating positive behavioral changes. The program can be applied to promote health at the community level.
