DEVELOPMENT OF THE “VHV CARB-COUNTING PROGRAM” TO PROMOTE HEALTHY CONSUMPTION AMONG DIABETES RISK GROUPS IN NONG KHAYANG DISTRICT, UTHAI THANI PROVINCE

Abstract

This participatory action research aimed to (1) assess the dietary behavior situation and problems, (2) develop the “VHV Carb-Counting Program”, and (3) evaluate its effects on knowledge and dietary behaviors among people at risk of diabetes in Nong Khayang District, Uthai Thani Province. The sample comprised 32 informants and 36 individuals at risk of diabetes, conducted from March to June 2026. Data were collected via in-depth interviews, focus groups, and questionnaires measuring knowledge, behaviors, and satisfaction. Data were analyzed using content analysis, descriptive statistics, and paired t-tests.

The results showed that 58.33% of the risk group were overweight or obese, 66.67% consumed sugar-sweetened beverages 4-5 days/week, and their carbohydrate counting knowledge was low to moderate. The program included carbohydrate counting education, nutrition label reading, practical carb calculation, VHV home visits, and LINE group follow-ups. After participation, mean knowledge scores significantly increased from 11.94±2.08 to 17.62±1.31, and dietary behavior scores improved from 2.86±0.39 to 4.18±0.37 (p-value < 0.001). Overall program satisfaction was at the highest level (Mean = 4.71, S.D. = 0.21). The VHV Carb-Counting Program effectively enhances knowledge and dietary behaviors, demonstrating high potential for application in healthcare settings and communities to prevent diabetes.
