目的：虽然饮食模式的方法来自饮食评估问卷被广泛使用，只有少数研究在西方国家报道了这种方法的有效性。我们研究了饮食模式的相对有效性来自一个自我管理的饮食史问卷（DHQ）在日本adultes.Design：DHQ，评估饮食在前一个月，和4天的饮食记录（DR），收集在每个季节超过一年。为了得出饮食模式，DHQ中的145种食物和DR中的1259种食物被分为33个预定义的食物组，并进入因子分析。（内陆农村）和鸟取研究对象：年龄在31-76岁的92名日本女性和92名日本男性。我们确定了三种饮食模式（“健康”，“西方”和“日本传统”）在妇女和两个（“健康”和“西方”）的男性，这表明了一个相对相似的方向和幅度的因素负荷的食物组在第一和平均的四个DHQ健康女性、西方女性和日本女性的DHQ 1和16 d DR之间的Pearson相关系数分别为0.57、0.36和0.44，而健康人和西方模式的男性分别为0.62和0.56。当检查mDHQ时，女性的相关系数提高（0.45-0.69）。结论：从DHQ得出的饮食模式可用于流行病学研究，作为从DR得出的饮食模式的替代品。
Objective: Although dietary pattern approaches derived from dietary assessment questionnaires are widely used; only a few studies in Western countries have reported the validity of this approach. We examined the relative validity of dietary patterns derived from a self-administered diet history questionnaire (DHQ) among Japanese adults.Design: The DHQ, assessing diet during the preceding month, and 4 d dietary records (DR) were collected in each season over one year. To derive dietary patterns, 145 food items in the DHQ and 1259 in the DR were classified into thirty-three predefined food groups, and entered into a factor analysis.Setting: Three areas in Japan; Osaka (urban), Nagano (rural inland) and Tottori (rural coastal).Subjects: A total of ninety-two Japanese women and ninety-two Japanese men aged 31-76 years.Results: We identified three dietary patterns ('healthy', 'Western' and 'Japanese traditional') in women and two ('healthy' and 'Western') in men, which showed a relatively similar direction and magnitude of factor loadings of food groups across the first and mean of four DHQ (DHQ1 and mDHQ, respectively) and 16 d DR. The Pearson correlation coefficients between DHQ1 and 16 d DR for the healthy, Western and Japanese traditional patterns in women were 0.57, 0.36 and 0.44, and for the healthy and Western patterns in men were 0.62 and 0.56, respectively. When mDHQ was examined, the correlation coefficients improved for women (0.45-0.69).Conclusions: Dietary patterns derived from the DHQ could be used for epidemiological studies as surrogates of those derived from DR.
