摘要

背景：在馬來西亞，心血管疾病為主要的死因。證據顯示，飲食中脂肪的攝取量為導致心血管疾病的一重要危險因子。然而，在馬來西亞，評估脂肪酸與心血管疾病罹患風險的相關研究仍非常稀少。因此，本篇研究的目的為開發評估馬來西亞的馬來人總脂肪和不同形式的脂肪攝取的食物頻率問卷（FFQ）及其效度。方法：該FFQ含100種食物項目，針對過去一個月內飲食膽固醇、總脂肪、飽和脂肪、單元不飽和脂肪、多元不飽和脂肪的攝取，並藉由151位馬來參與者三天的飲食紀錄進行效度評估。效度的評估是透過信度以及頻率問卷及飲食紀錄兩種方式的一致性。信度用組內相關係數來評估；兩種方法的一致性以迴歸分析和類別資料分析來評估。結果：相較DR，FFQ有較高的平均營養攝取量。這個FFQ有極佳的信度，其組內相關係數範圍為0.92-0.98。迴歸分析指出FFQ和DR兩者在總脂肪以及不同形式的的脂肪攝取，具有可接受的一致性。相對較高比例的參與者被正確分類（相同或相近的類別），只有少數在總能量攝取、脂肪、膳食膽固醇、飽和脂肪和非飽和脂肪被嚴重的錯誤分類。結論：這個FFQ能有效地評估馬來人飲食中總能量攝取、總脂肪和不同形式脂肪攝取量。

Background: Cardiovascular diseases are the major cause of death in Malaysia. Evidence shows that dietary fat intake is one of the important risk factors for cardiovascular disease. However, studies assessing the association of fatty acids and risk of cardiovascular diseases in Malaysia are scarce. Therefore, this study aimed to develop and validate a food frequency questionnaire (FFQ) assessing total fat and different types of fat among Malay adults in Malaysia. Methods: A 100 food item FFQ focused on dietary cholesterol, total fat, saturated fat, monounsaturated fat and polyunsaturated fat intake for the past one month was developed and validated against 3-day dietary record (DR) among 151 Malay participants. Validity was assessed through the reliability and agreement of two methods. Intra-class correlation (ICC) coefficients were used to assess reliability; while regression analysis and classification into categories were used to assess agreement of the two methods. Results: The mean nutrient intakes tended to be higher in FFQ compared to DR. The developed FFQ showed excellent reliability with ICC coefficients ranging from 0.92-0.98. Regression analysis demonstrated an acceptable agreement between FFQ and DR for total fat and different types of fat intakes. There were a relatively high proportion of subjects being correctly classified (into same or adjacent category) and only a small number of grossly misclassification for total energy, fat, dietary cholesterol, saturated fat and unsaturated fat occurred. Conclusion: This FFQ is valid in assessing absolute total energy, total fat and types of fat intakes among Malay adults.
