Abstract

Background: Overweight and obesity were associated with increased energy intake therefore an effective approach to prevent the excess intake of energy is warranted. The Indonesian Ministry of Health has recently published the new nutrition guideline that aimed to improve dietary practice and to reduce nutrition related problems. Objective: The aim of this study was to examine the effect of an educational movie on nutritional knowledge, eating habit and dietary intake in overweight/obese adolescents.  Method: A total of 80 overweight/obesity subjects aged 15 to 17 years old participated in this study. Those subjects were divided into two groups: control group (lecture only) and movie group (lecture + movie). Nutritional knowledge, eating habit and dietary intake were measured before and after the intervention. Result: Both groups had increment in nutritional knowledge after the intervention but movie group had higher increment than those in control group (p<0,05). Dietary intake was reduced in both groups and subjects in movie group had significantly higher reduction in energy intake after the first month of intervention (p<0,05). Interestingly, subjects in movie group significantly reduced consumption on fried foods (p<0,0001), snacks (p=0,037), sugar (p=0,015) and increased consumption on vegetables (p=0,029). Those effects were not seen in control group.  Conclusion: In conclusion, we showed that an educational movie on a school based promotion of nutrition guideline was effectively increased nutritional knowledge, improved eating habits, and reduced energy intake of overweight/obese adolescents.
