Background: Childhood obesity has become more prevalent all over the globe. In Thailand, the highest prevalence rate of childhood obesity has been found among primary school students in Northeastern (9.9%), which still exceeds 7% recommended by the WHO. Objective: This study aimed to assess the effectiveness of Food Fit for Fun program with social media used on health literacy and obesity prevention behaviors among senior-primary school students in Nakhon Ratchasima Province, Thailand. Methods: A quasi-experimental was conducted. An experimental and a control group each with 34 participants. A 12-week program was implemented with Health Literacy on dietary and physical activities and social media were used for communication and support. Analysis of the data was performed using t-test while a mean difference and 95%CI were used for determining statistical significance. Results: The senior-primary school children in the experimental group improved their mean difference on health literacy in preventing obesity (10.18; 95% CI: 7.11 to 13.24, p-value <0.001) and dietary and physical activity behaviors (13.44; 95% CI: 6.11 to 20.77, p-value <0.001), compared to the control group. After interventions, the experimental group had a statistically significantly lower mean score on nutritional status (weight for height) (0.26; 95% CI: 0.05 to 0.59, p-value <0.05) and fat percentage (1.71; 95% CI: 0.19 to 3.22, p-value <0.05) than the comparison group. Conclusions: This study provided sustainable evidence on effectiveness of Food Fit for Fun program with the use of social media.
