- This study was conducted to investigate the validity of using a cameraphone for a dietary intake survey method. The subjects were 28 female college students. After eating a standard lunch meal which consisted of plain rice, seaweed soup, bulgogi, cucumber salad, roasted anchovy and kimchi, the quantity of dietary intake, calorie intake & nutrients intake were analyzed by weighed method, diet record method and cameraphone method by dietitian with & without cameraphone analysis training. There were no significant differences in the quantity of 6 foods intake between weighted method and cameraphone method by dietitians with camera phone analysis training. However, the quantity of seaweed soup, bulgogi & cucumber salad intake analyzed by diet record method was significantly lower than the weighed method. And the quantity of seaweed soup, bulgogi, cucumber salad, roasted anchovy and kimchi intake analyzed by the cameraphone method by dietitians without cameraphone analysis training was significantly lower than the weighed method. There were no significant differences in the calorie intake and nutrients intake between the weighted method and camera phone method by dietitians with camera-phone analysis training. However, protein, calcium, iron, phosphorous, Vitamin A, Vitamin B2, Vitamin E and cholesterol intake analyzed by diet record method was significantly lower than the weighed method. And fat and Vitamin B2 intake analyzed by the camera phone method by dietitians without cameraphone analysis training was significantly lower than the weighed method. Therefore, this study suggests that the use of the camerephone may be a valid and convenient method for evaluating a dietary intake survey. However, systematic and standard education is necessary about the size and volume of dishes and angle of photo for more accurate results.
