食物频率调查问卷包括七类食物类型和 266 个食物项目，旨在对香港华人进行饮食调查。借助照片来记录每种食物的数量、每天和每周的食用频率，以说明份量大小，并使用来自多个来源（英国和两家中国大陆机构）的食物表计算营养成分。通过比较计算的 24 小时总能量、钠和钾摄入量与能量消耗 (BMR x 1.4)、24 小时尿钠和钾排出量的估计值来检查营养定量的有效性。除了可能低估了钠和钾的摄入量之外，能量的计算值也接近估计值。能量摄入、胆固醇、脂肪和脂肪酸摄入以及血清脂质谱之间也存在关联。结论是，该问卷适用于香港华人的饮食调查，并可用于在将膳食成分作为危险因素进行研究的研究中对营养素摄入量进行定量。 (C) 1997 爱思唯尔科学公司。
A food frequency questionnaire consisting of seven categories of food types and 266 food items was developed for a dietary survey of the Hong Kong Chinese population. The quantity, frequency of consumption per day and per week for each item was recorded with the aid of photographs to illustrate portion sizes, and nutrient quantity calculated using Food Tables from multiple sources - UK and two mainland Chinese institutions. The validity of the nutrient quantitation was examined by comparing calculated 24 hour intake of total energy, sodium, and potassium, with estimated values of energy expenditure (BMR x 1.4), 24h urinary sodium and potassium outputs. Apart from probable underestimation of sodium and potassium intake, calculated values for energy were close to estimated values. Associations were also present between energy intake, cholesterol, fat, and fatty acid intakes, and serum lipid profile. It is concluded that this questionnaire is suitable for dietary surveys in Hong Kong Chinese and may be used for quantitation of nutrient intakes in studies examining dietary components as risk factors.
