目的：设计一套基于数据的半定量食物频率问卷（SQFFQ），覆盖广东省潮汕地区的城市和农村地区，调查中国中年人食物摄入与生活方式相关疾病的关系。方法：我们从普通人群中招募了417名受试者，并使用三维称重饮食记录调查对饮食进行评估。我们采用贡献分析（CA）和多元回归分析（MRA）分别选择了贡献高达90%和0.90 R(2)的食品。总食物摄入量为523种（城市人口443种，农村人口417种），29种营养素的摄入量是按食物/食谱的实际摄入量计算的。结果CA分别为城市和农村地区选择了233、194和183种食物/食谱，MRA分别为196、157和160种。最终，125种食物/食谱被选为最终问卷。频率被分为八类，标准份量也被计算出来。为了采用区域特异性SQFFQ，现在计划进行有效性和可重复性试验，以确定联合SQFFQ在疾病风险和获益的实际评估中的表现。
AIM This paper aims to develop a data-based semi-quantitative food frequency questionnaire (SQFFQ) covering both urban and rural areas in the Chaoshan region of Guangdong Province, China, for the investigation of relationships between food intake and lifestyle-related diseases among middle-aged Chinese. METHODS We recruited 417 subjects from the general population and performed an assessment of the diet, using a 3-d weighed dietary record survey. We employed contribution analysis (CA) and multiple regression analysis (MRA) to select food items covering up to a 90% contribution and a 0.90 R(2), respectively. The total number of food items consumed was 523 (443 in the urban and 417 in the rural population) and the intake of 29 nutrients was calculated according to the actual consumption by foods/recipes. RESULTS The CA selected 233, 194, and 183 foods/recipes for the combined, the urban and the rural areas, respectively, and then 196, 157, and 160 were chosen by the MRA. Finally, 125 foods/recipes were selected for the final questionnaire. The frequencies were classified into eight categories and standard portion sizes were also calculated. CONCLUSION For adoption of the area-specific SQFFQ, validity and reproducibility tests are now planned to determine how the combined SQFFQ performs in actual assessment of disease risk and benefit.
