Abstract

A comprehensive dietary assessment tool to capture data on the wide variety of food and nutrient intakes across different regions and ethnic groups is needed to establish diet-disease relationship. Therefore the aim of this study is to develop a computer-based, interviewer-administered dietary assessment system linked to a nutrient database. This dietary assessment system or Dietary Information Management System (DIMS) consist of three modules i.e. a nutrient database, an interactive computerized 24-h diet recall and finally the computerized semi-quantitative food frequency questionnaire (FFQ). A sub-sample of 10,000 participants was purposely selected from 106,527 participants of The Malaysian Cohort (TMC) project for the development of DIMS nutrient database module and 24-h diet recall module. Further, a sub-sample of 800 participants based on good quality data of a single 24-h diet recall and 2-d diet record were selected to represent the TMC participants for the development of food item list in the FFQ module. DIMS, which managed to include more than 2,500 items of food and beverages in the nutrient database module, finally listed 203 food items and cooked dishes retrieved using step-wise multiple regression analysis into the FFQ module. The FFQ module was designed using the habitual intake of mixed dish-based approach, frequency of intake, portion size and linked to the nutrient database module. Images of food items were also included to aid food intake estimation. At the end of interview session, the DIMS could generate an output explaining diet quality for participant's easy reference. A preliminary validation study using a paper format for the selected food list in FFQ module was conducted in another group of participants (n=103) prior to constructing the system and showed promising results when compared to the reference method. This well-accepted system provides a culturally specific automated dietary assessment system for measuring habitual food and nutrient intake in order to establish diet-disease relationship across the multi-ethnic population of Malaysia.
