Purpose: This study aimed to assess the effects of a dietary modification program on a food consumption behavior.

Design: An experimental design.

Methods: 60 people with prediabetes were participated in this study. Participants were randomly assigned into experimental and control groups with 30 each. Participants in the experimental group received usual care plus the dietary modification program whereas those in the control group received only usual care. The 8-week dietary behavior modification program consisted of 4 sessions of group activities and a follow-up telephone call. Data collection was performed using questionnaires at based line, after intervention (week 4), and follow-up period (week 8). Descriptive statistics and repeated measure one-way ANOVA were used for data analysis.

Main findings: The study findings revealed that food consumption behavior, health belief and perceived self-efficacy of the experimental group significantly differed from the control group (F(1,58) = 38.096, p < .001, F(1, 58) = 26.374, p < .001 and F(1, 58) = 26.555, p < .001).

Conclusion and recommendations: The dietary modification program could modify food consumption behavior among people with prediabetes. Participants in the experimental group were more confident to choose proper food according to their prediabetic stage and had better health beliefs than those of the control group. Thus, community health nurse practitioners should apply this program in promoting dietary change for people with prediabetes in order to prevent or delay the onset of diabetes mellitus in the future.
