Development of Web - Page for Assessment of Snack and Beverage Consumption among Adolescent Students

Abstract

Background and objectives: The development of Web-page is the application of information technology as a tool for dietary assessment. The aimed of this study was to develop and validate a web - page for assessment of snack and beverage consumption among adolescent students.  

Methods: The web-page contained a database of 142 snack and beverage items. The web-page for assessing snack and beverage among adolescent 110 primary school students, Demonstration School of Khon Kaen University. Snack and beverage intake was assessed using the web-page and 3-days 24-hours dietary recall. Spearman correlation coefficients were used to analyze the association of energy and nutrient intakes between the two methods. Bland-Altman plots and Cohen’s Kappa were used to analyze the measuring agreement.

Results: The energy, carbohydrate, sugar and sodium intakes were statistically significant correlation between Web-page and 3-day 24-hour dietary recall. The correlations coefficient of energy and the three nutrient intakes between two methods were high (r=0.86 – 0.98). The Bland-Altman plots showed that the difference between the two methods were inside the limit of agreement for energy and the three nutrients. The weighted kappa analysis show that agreement of energy and the three nutrients were substantial to almost perfected (K_w=0.78–0.92).

Conclusion: The web-page for assessing snack and beverage consumption provides reasonably valid measurement for assessing of energy and nutrient intakes of adolescent students.
