Abstract:
At present, methods of water-intake survey include government, industry, sector statistics data, dietary survey (24 hours dietary recall, dietary record and food frequency questionnaire), fluid intake survey (retrospective fluid-intake questionnaire, 1-5 days 24 hours fluid-intake survey, 7 days 24 hours fluid-intake record), weighing method with the food composition table, weighing method, duplicate portion method and chemical analysis, and so on. The method of 7 days 24 hours fluid-intake record is an internationally recognized and authoritative method for fluid-intake survey with the highest accuracy, which can reflect the differences of fluid intake between working and non-working days, and can obtain detailed data on behaviors and patterns of fluid water, such as the time, types and places of fluid intake. The method of combining weighing method, duplicate portion method and chemical analysis is used to analyze water intake from food with the highest accuracy, which can be used in an extensive range of population and areas, but with high cost and complex operating steps. It is of great practical significance to compare and evaluate the advantages and disadvantages of different methods about water-intake survey, which will be helpful for researchers to choose appropriate methods for water-intake survey to obtain accurate and representative data in various areas, different population, and complex circumstances.
