Development of a nutrition program for Koreans with type 2 diabetes based on the health belief model: a pre-post intervention study.
Article in Korean journal of community nutrition, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectivesTo evaluate the effectiveness of a health belief model (HBM)-based nutrition education program in improving dietary behaviors, nutrition knowledge, and self-management among Koreans with type 2 diabetes mellitus (T2DM), and to examine age-related differences and the effects of intervention delivery strategies.
methodsA pre-post intervention study was conducted among 21 adults with T2DM (glycated hemoglobin levels ≥ 7.5%) attending outpatient clinics at university hospitals in Korea. The HBM-based program incorporated passive learning strategies (lectures and videos) and active, experiential learning strategies. Nutrition knowledge, dietary attitudes, and dietary behaviors were assessed before and after the intervention. Participants' interest and satisfaction were also evaluated using interest-satisfaction analysis (ISA).
resultsNutrition knowledge and dietary behaviors improved significantly among adults following the intervention. Adults (n = 15) showed significant increases in nutrition knowledge (0.50 to 0.60, P < 0.05) and dietary behavior scores (2.26 to 2.47, P < 0.05), whereas no significant changes were observed among older adults (n = 6). The mean interest and satisfaction scores were 4.44 and 4.43 out of 5, respectively. Experiential learning strategies were associated with higher satisfaction than passive approaches. ISA showed that hands-on activities received the highest interest and satisfaction ratings, whereas passive methods were rated less favorably.
conclusionParticipation in an HBM-based nutrition education program was associated with improved dietary behaviors among Koreans with T2DM in a clinical nutrition setting. Experiential learning approaches appeared to be more effective than passive methods, and the age-related differences observed suggest a need for tailored intervention strategies. These findings support the development of scalable, patient-centered nutrition interventions for chronic disease management.
