ABSTRACT
@#Introduction: The dietary intake of adults in Brunei Darussalam has not been thoroughly investigated via the food frequency questionnaire (FFQ). This study aimed to establish, validate and test the reproducibility of an FFQ to determine and evaluate the adult dietary intake in Brunei Darussalam. Methods: Participants were divided into; (1) development phase (50 adults); (2) validation phase (100 adults); (3) reproducibility phase (subsample of 40 adults). 3-day dietary record (3DR) was used in development phase to gather food items consumed. 2-day dietary record(2DR) was used as a reference method in validation. Nutrients analyze were energy, macronutrients, calcium, and vitamins A and C. Validation analysis were spearman correlation, mean difference, Bland-Altman plot, cohen’s kappa and cross-classification analyses. Reliability analyses were intra-class correlation coefficient (ICC), Cronbach’s alpha and cross classification to compare repeat FFQ administered with 1 to 3 months interval. Results: The FFQ consisted 138 food items from 12 food groups. In validation, mean difference between FFQ and 2DR exceeded 10%, spearman correlation were significantly strong (r=0.994 to r=0.107). Cross-classification demonstrated > 50% of nutrients were correctly and adjacently classified, Bland-Altman plots were relatively consistent for the two methods. Cohen’s kappa ranged from 0.081 to 0.040, demonstrating weak agreement. In reproducibility, ICC outcomes for FFQ1(0.463) and FFQ2(0.978), Cronbach’s alpha was > 0.8, and > 95% of the nutrients were correctly or adjacently classified. Conclusion: The FFQ designed in this study was valid due to the consistency with the dietary records; hence, a reliable tool to predict the dietary intake of Brunei Darussalam adults.
ABSTRACT
Background: Studies from the West have demonstrated that ready-to-eat cereals (RTECs) are a common form of breakfast and more likely to be consumed by children. This study aimed to investigate the breakfast eating pattern and RTECs consumption among schoolchildren in Kuala Lumpur. Methods: In this cross-sectional study, a total of 382 schoolchildren, aged 10 and 11 years old, were recruited from seven randomly selected primary schools in Kuala Lumpur. Information on socio-demographics, breakfast eating patterns, and perceptions of RTECs and dietary intake (24-hour dietary recalls) were obtained. Results: Among the respondents, only 22% of them consumed breakfast on a regular basis. The most commonly eaten food by children at breakfast was bread (27.2%), followed by biscuits (22.2%) and RTECs (20.5%). The majority of them (93%) reported that they consumed RTECs sometimes during the week. Chocolate RTECs (34.1%), corn flake RTECs (30.3%), and RTECs coated with honey (25.1%) were the most popular RTECs chosen by children. Respondents who consumed RTECs showed a significantly higher intake in calories, carbohydrate, vitamin A, vitamin B1, vitamin B2, vitamin B3, folate, vitamin C, calcium, iron, and fibre (P < 0.05), compared to those who skipped breakfast and those who had breakfast foods other than RTECs. Conclusion: The lower levels of breakfast consumption among schoolchildren in Kuala Lumpur need serious attention. RTEC is a nutritious food which is well accepted by a majority of the schoolchildren in Kuala Lumpur. Nutrition intervention should be conducted in the future to include a well-balanced breakfast with the utilisation of RTECs for schoolchildren.
