This study was conducted to explore portion size estimation by comparing the measurement errors of food and macronutrient intake by photography estimation and 24-hour recall from weighing method. A total of 28 female participants aged 20-24 years old were provided a meal that included rice, chard soup with soybean paste, stir-fried squid, japchae, stirfried boiled fish paste, lettuce geotjeori, and kimchi. Each portion was measured accurately, and food intake was measured using three dietary assessment methods. For the photography method, trained researchers estimated remaining food amount by analyzing photographs using a mean of four times. The measurement errors for the stir-fried squid and japchae were larger by the 24-hour recall method, while the error for kimchi was larger by the photography method. The correlation coefficients for each food, except chard soup with soybean paste, between the weighing method and photography method were 0.770.99 (p0.001). The correlation coefficients of energy and intake of macronutrients between the weighing method and photography method were 0.850.86 (p0.001). The results of this study demonstrate substantially less measurement error using the photography method than the 24-hour recall method. However, further research is needed to standardize various kinds of foods, photograph angles, serving plates, and serving style for establishment of reliable and valid portion size estimation using the photography method.
