To assess the relative validity of food frequency questionnaire( FFQ) for estimating dietary nutrients and food intakes.
Using random sampling methods to select 200 people from Minhang District and Jinshan District. Dietary intakes were estimated by weighed dietary records combining with 24 h dietary recalls( as reference method) and food frequency questionnaire. Relative validity were examined by T-test, Wilcoxon rank test and correlation analysis.
The foods groups were the same in FFQ and 24 h dietary recalls. Correlated with daily intake of grains, beans and products, vegetables, cruciferous vegetables, fruits, meat and poultry, aquatic product, milk and products in two methods( Correlation coefficients: 0. 248- 1. 000). The daily food of energy, protein, fat, carbohydrate, cholesterol had significantly positive correlation in FFQ and 24 h dietary recalls( Correlation coefficients: 0. 209- 0. 340). No statistical difference in energy and fat. The daily food of Mg, K, P, Mn, I, Ca, Se had significantly positive correlation in two methods( Correlation coefficients: 0. 204-0. 419). No statistical difference in Mg, K, P, Mn, I. The daily food of vitamin B1、B2、C、niacin had significantly positive correlation in two methods( Correlation coefficients:0. 170- 0. 305). No statistical difference in vitamin B1、B2.
Food frequency questionnaire can be used to evaluate dietary intakes of I, cruciferous vegetables, soy isoflavones, energy, fat, Mg, K, P, Mn, vitamin B1 and vitamin B2.
评估食物频率问卷（FFQ）在估计膳食营养素和食物摄入量方面的相对有效性。
采用随机抽样方法从闵行区和金山区选取200人。膳食摄入量通过称重膳食记录结合24小时膳食回顾（作为参考方法）和食物频率问卷进行估计。通过t检验、Wilcoxon秩和检验及相关分析来检验相对有效性。
FFQ和24小时膳食回顾中的食物类别相同。两种方法中谷物、豆类及其制品、蔬菜、十字花科蔬菜、水果、畜禽肉、水产品、奶类及其制品的每日摄入量具有相关性（相关系数：0.248 - 1.000）。FFQ和24小时膳食回顾中能量、蛋白质、脂肪、碳水化合物、胆固醇的每日食物摄入量具有显著正相关（相关系数：0.209 - 0.340）。能量和脂肪无统计学差异。两种方法中镁、钾、磷、锰、碘、钙、硒的每日食物摄入量具有显著正相关（相关系数：0.204 - 0.419）。镁、钾、磷、锰、碘无统计学差异。两种方法中维生素B1、B2、C、烟酸的每日食物摄入量具有显著正相关（相关系数：0.170 - 0.305）。维生素B1、B2无统计学差异。
食物频率问卷可用于评估碘、十字花科蔬菜、大豆异黄酮、能量、脂肪、镁、钾、磷、锰、维生素B1和维生素B2的膳食摄入量。
