Introduction:
Obesity among military personnel has become a serious issue. This study aimed to verify the effectiveness of an obesity management program based on an information-motivation-behaviour skills model using a mobile application and social media among military personnel with obesity in the Republic of Korea.
Methods:
A one-group pretest-posttest design was employed to investigate the effects of the program. Thirty individuals participated in an obesity management program for 12 weeks. Body mass index, body fat percentage, and waist circumference were measured, and dietary practices, physical activity, perceived health status, and depressive symptoms were assessed using self-report questionnaires. Analysis was performed using a generalized estimating equation.
Results:
Dietary practices (β = 0.674, p = 0.002) and health status (β = 0.330, p ≤ 0.001) increased, whereas body mass index (β = -0.303, p = 0.001), fat percentage (β = -0.599, p = 0.005), and waist circumference (β = -0.936, p = 0.023) decreased over time during the program.
Discussion:
The program effectively improved target health behaviours and outcomes in obesity management and, therefore, could be used as a practical obesity management strategy for military personnel with obesity, regardless of time and location restrictions.
