Use and Evaluation of a Website for Dietary Assessment

The purpose of this study was to investigate dietary habits and nutrient intake of college students through 'idiet' website and evaluate satisfaction of the website. The subjects were 166 students who registered 'food and nutrition' as a general education course in Chungbuk National University. Dietary habits, dietary attitudes, food frequency, and dietary intake were investigated through the 'idiet' website by himself/herself. More than two thirds(69.3%) of the subjects were categorized as 'poor' in dietary habits, and 36.7% were categorized as 'poor' in dietary attitudes. Nutrient intakes were estimated on the website when the students chose the name and the amount of the foods they ate during 24 hours with the help of real-size photos provided on the website. Mean daily energy intakes were 2,146 kcal, and 1,667 kcal in male and female students, respectively, which were comparable with those published in the previous studies estimated though a 24-hour recall or a food record method. Mean daily intakes of vitamin C, riboflavin and calcium were less than 75% of Recommended Intakes. Nutrient intakes of the subjects who were categorized as 'good' in dietary habits and food frequency were significantly higher than those who were categorized as 'poor'. The usefulness of the contents were evaluated by the subjects after using the website and the results showed that the usefulness score of nutrient intake assessment was high. Seventy five percents of the subjects answered that the website might be helpful for weight control, and 71.7% would recommend this website to others, and 68.1% would revisit this website. These results showed that the website might be useful for examining dietary habits, dietary attitudes, food frequency, and dietary intake of college students.
