摘要

为了研究短期自我管理的食物频率问卷与7天称重饮食记录之间关于纤维和脂肪消耗的一致性程度,我们收集了随机选择的92名瑞典中年男性的信息。参与者首先通过数字秤记录了连续7天内消耗的所有食物和饮料。7天体重记录完成一个月后,研究人员向受试者发送了一份自我管理的食物频率问卷,调查他们在前一个月习惯性地食用含有纤维或脂肪的食物。根据7天的体重记录,饮食中纤维和脂肪含量最高的20种食物分别占总摄入量的71%和52%。根据7天的体重记录,估计平均纤维摄入量为每天19.0克,根据食物频率调查问卷,估计平均纤维摄入量为每天18.3克。相应的估计平均脂肪摄入量是每天88.6克,而不是每天46.9克。体力活动多的男性和身体质量指数低的男性分别摄入了更多的纤维和脂肪。这些差异在两种饮食测量方法中都可以看到,但在使用7天体重记录时更为明显。还评估了每个个体的方法之间的一致性。根据五类纤维消耗量,根据7天体重记录,61%的受访者属于食物频率调查问卷中两个最高的五分之一。相应的脂肪摄入量是56%。我们的结论是,本研究中使用的短期自我管理的食物频率问卷可以评估纤维的绝对摄入量,但不能评估脂肪的绝对摄入量,精度很高。此外,在纤维和脂肪消费的广泛类别中,个人的排名在很大程度上并没有根据这个简短的问卷进行错误分类。

Food frequency questionnaire versus 7-day weighed dietary record information on dietary fibre and fat intake in middle-aged Swedish men.

To study the magnitude of agreement between a short self-administered food frequency questionnaire and a 7-day weighed dietary record regarding the consumption of fibre and fat, we collected information from 92 randomly selected middle-aged Swedish men. The participants first recorded all foods and drinks consumed over seven consecutive days by means of a digital scale. One month after the 7-day weighed record had been completed, a self-administered food frequency questionnaire on habitual consumption of foods containing fibre or fat during the preceding month was sent to the subjects. The 20 largest contributors of fibre and fat in the diet accounted for 71% and 52% of the total intake, respectively, based on the 7-day weighed record. The estimated mean consumption of fibre was 19.0 grams per day based on the 7-day weighed record and 18.3 grams per day based on the food frequency questionnaire. Corresponding estimated mean consumption of fat was 88.6 grams per day versus 46.9 grams per day. Men with high physical activity and low BMI, respectively, had higher intake of fibre and fat. These differences were seen for both dietary measurement methods but were more marked using the 7-day weighed record. The agreement between methods for each individual was also assessed. Based on five categories of fibre consumption, 61% of the respondents in the highest quintile according to the 7-day weighed record were classified in one of the two highest quintiles according to the food frequency questionnaire. The corresponding figure for fat intake was 56%. We conclude that the short self-administered food frequency questionnaire used in the present study can assess the absolute intake of fibre, but not of fat, with good precision. Also, the ranking of individuals in broad categories of consumption of fibre and fat was not largely misclassified based on this short questionnaire.
