Energy content estimation by collegians for portion standardized foods frequently consumed in Korea.

Kim J, Lee HJ, Lee HJ, Lee SH, Yun JY, Choi MK, Kim MH - Clin Nutr Res (2014)

Bottom Line: Female students were more likely to check energy content of foods that they consumed than male students.From these results, it was concluded that the knowledge on food energy content was poor among collegians, with some gender difference.Therefore, in the future, nutrition education programs should give greater attention to improving knowledge on calorie content and to helping them apply this knowledge in order to develop effective dietary plans.

ABSTRACT
The purpose of this study is to estimate Korean collegians' knowledge of energy content in the standard portion size of foods frequently consumed in Korea and to investigate the differences in knowledge between gender groups. A total of 600 collegians participated in this study. Participants' knowledge was assessed based on their estimation on the energy content of 30 selected food items with their actual-size photo images. Standard portion size of food was based on 2010 Korean Dietary Reference Intakes, and the percentage of participants who accurately estimated (that is, within 20% of the true value) the energy content of the standard portion size was calculated for each food item. The food for which the most participants provided the accurate estimation was ramyun (instant noodles) (67.7%), followed by cooked rice (57.8%). The proportion of students who overestimated the energy content was highest for vegetables (68.8%) and beverages (68.1%). The proportion of students who underestimated the energy content was highest for grains and starches (42.0%) and fruits (37.1%). Female students were more likely to check energy content of foods that they consumed than male students. From these results, it was concluded that the knowledge on food energy content was poor among collegians, with some gender difference. Therefore, in the future, nutrition education programs should give greater attention to improving knowledge on calorie content and to helping them apply this knowledge in order to develop effective dietary plans.

Figure 1: The proportion of participants who checked the energy content of eating food. *Significance between Male and Female as determined by χ2-test.

Mentions: Table 1 shows the general information of the subjects. The average age of participants was 21.1 years. The height (p < 0.001) and weight (p < 0.001) were significantly higher in the male group than in the female group. Regarding the body mass index (BMI, 22.6 kg/m2 in male vs. 20.7 kg/m2 in female), there was also a significant difference between the two groups (p < 0.05). The proportions of underweight and normal weight participants were significantly higher in the female group than those in the male group; however, the proportions of overweight and obese participants were significantly higher in the male group (p < 0.001). The proportion of the females who checked energy content for consumed foods was significantly higher than that of the males (40.6% for the females and 24.2% for the males; p < 0.001) (Figure 1).
