【摘要】：目的以称重记录法结合24 h回顾法为参考方法,评估食物频率问卷法(FFQ)应用于调查人群膳食营养素和食物摄入量的相对效度。方法采用随机抽样的方法在上海市抽取闵行区和金山区居民作为调查对象。使用称重法结合24 h膳食回顾法与食物频率问卷法对调查对象进行膳食调查,并以称重法结合24 h膳食回顾法作为标准,采用t检验,Wilcoxon秩和检验及相关系数检验对食物频率问卷所得数据进行统计分析。结果 FFQ和24 h回顾调查2种方法食用的食物大类相同,获得的谷类、豆类及其制品、蔬菜、十字花科蔬菜、水果、肉禽水产类以及奶及奶制品的每日摄入量有相关性(相关系数0.248~1.000)。FFQ和24 h回顾调查2种方法获得的能量、蛋白质、脂肪、碳水化合物、胆固醇每日摄入量均呈显著正相关(相关系数0.209~0.340),其中能量与脂肪无统计学差异;镁、钾、磷、锰、碘、钙与硒每日摄入量呈显著正相关(相关系数0.204~0.419),其中镁、钾、磷、锰、碘元素无统计学差异;维生素B1、B2、C、烟酸每日摄入量均呈显著正相关(相关系数0.170~0.305),其中维生素B1、B2无统计学差异。结论食物频率问卷可以评估碘元素、十字花科蔬菜、大豆异黄酮以及能量、脂肪、镁、钾、磷、锰、维生素B1和维生素B2摄入量。
[Abstract]:Objective to use weighing record method combined with 24 h retrospective method as reference method, Food frequency questionnaire (FFQ) was applied to investigate the relative validity of dietary nutrients and food intake. Methods the residents of Minhang District and Jinshan District in Shanghai were selected by random sampling. The subjects were investigated by reassessment method combined with 24 h dietary review method and food frequency questionnaire. The weight method combined with 24 h dietary review was used as the standard. The data obtained from food frequency questionnaire were statistically analyzed by t test and Wilcoxon rank sum test and correlation coefficient test. Results FFQ and 24 h retrospective investigation showed that the two methods had the same food categories, and obtained cereals, beans and their products, vegetables, etc. There was a correlation between daily intake of cruciferous vegetables, fruits, meat, poultry and aquatic products, as well as milk and dairy products (correlation coefficient 0.248~1.000).FFQ and 24 h retrospective survey of energy, protein, fat, carbohydrates obtained by the two methods. There was a significant positive correlation between daily cholesterol intake (correlation coefficient 0.209 ~ 0.340), energy and fat, magnesium, potassium, phosphorus, manganese, iodine, calcium and daily intake of selenium (correlation coefficient 0.204 ~ 0.419), among which magnesium, potassium, phosphorus, manganese, magnesium, potassium, phosphorus, manganese, magnesium, potassium, phosphorus, manganese, magnesium, potassium, phosphorus, manganese, magnesium, potassium, phosphorus, manganese, magnesium, potassium, phosphorus, manganese, magnesium, potassium, phosphorus, manganese. There was no statistical difference in iodine, and there was a significant positive correlation between daily intake of vitamin B _ 1 B _ 2C and niacin (correlation coefficient was 0.170 ~ 0.305), among which vitamin B _ 1 and B _ (2) had no statistical difference. Conclusion the food frequency questionnaire can be used to evaluate iodine and cruciferous vegetables. Soy isoflavones and energy, fat, magnesium, potassium, phosphorus, manganese, vitamin B1 and vitamin B2 intake.
