Few studies have examined the validity of adolescent diet as recalled by adults many years later.
In this investigation, we examined the validity of a 124-item food frequency questionnaire (HS-FFQ) completed by 80 young adults in the United States about their diet during high school. We compared the HS-FFQ with 3 24-hour recalls and 2 food-frequency questionnaires (YAQ) collected 10 years earlier in 1993, when the participants were in high school. We calculated Pearson correlation coefficients for 20 to 25 nutrients and corrected these correlations for within-person variation.
The average corrected correlation for energy-adjusted nutrient intakes calculated from the HS-FFQ and the 24-hour recalls was 0.45 (range = 0.16-0.68). The mean corrected correlation between the HS-FFQ and YAQs was 0.58 (range = 0.40-0.88).
Taken together with the results of our earlier work, this analysis suggests that the HS-FFQ can reasonably capture adolescent diet recalled by young adults.
很少有研究检验多年后成年人回忆的青少年时期饮食的有效性。
在本调查中，我们检验了美国80名年轻成年人填写的一份包含124个条目的食物频率问卷（HS-FFQ）关于他们高中时期饮食的有效性。我们将HS-FFQ与10年前（1993年）参与者在高中时收集的3次24小时饮食回顾及2份食物频率问卷（YAQ）进行比较。我们计算了20至25种营养素的皮尔逊相关系数，并针对个体内变异对这些相关性进行校正。
根据HS-FFQ和24小时饮食回顾计算的能量调整营养素摄入量的平均校正相关系数为0.45（范围=0.16 - 0.68）。HS-FFQ与YAQ之间的平均校正相关系数为0.58（范围=0.40 - 0.88）。
结合我们早期工作的结果，该分析表明HS-FFQ能够合理地反映年轻成年人回忆的青少年时期饮食。
