loss motivation and physical activity in obese female students
Nutrition education and motivational interviewing are methods to increase motivation, as essential factors in increasing physical activity. The purpose of this study was to determine the effect of nutrition education via Instagram and motivational interviewing, on weight loss motivation and physical activity of obese female students. This study was quasi-experimental with a pre-post-controlled group design that involved thirty-seven obese female students aged 18-23 years at Universitas Diponegoro, selected by proportional stratified sampling. Subjects were divided into three groups, P1 was given nutrition education via Instagram for 30 days (ED) and motivational interviewing four times (MI), P2 was given ED only, and the control (K) was given a leaflet. Weight loss motivation was measured using a healthy diet motivation questionnaire, and physical activity (PA) was measured using IPAQ-SF. Data were analyzed using one way ANOVA, Kruskal Wallis, paired t-test, Wilcoxon, and Mann Whitney. There was an increase in the mean of weight loss motivation that highest in group P1 (109.86 into 126.43), followed by group P2 (114.85 into 121.69) and group K (105.30 into 112.90). The highest increase in the mean of total physical activity was in the P1 group (1341 to 2572), the P2 group (1761 to 2378), and the K group decreased (3404 to 1987) in METs units. There was a significant difference in the mean change in total physical activity and moderate physical activity between P1 and P2 groups when compared to the K group.
