我们研究了季节性对有效性（估计一组的平均摄入量和排名能力的能力）的营养素摄入量的影响，估计与一个全面的自我管理的饮食史问卷（DHQ）开发的评估日本饮食在前一个月，使用半称重的饮食记录（DR）作为参考方法。本研究在日本的三个地区（大坂、长野和鸟取）进行。研究人群包括92名32-76岁的日本男性和92名31-69岁的日本女性（每种性别30名来自大坂，31名来自长野，31名来自鸟取）。DHQ和为期四天的DR以3个月的间隔完成四次，每个季节一次。季节性的影响进行了检查，使用平均营养摄入量和相关系数的季节之间的协议水平。在估计的能量调整摄入量的42个选定的营养素之间的平均DR管理16次，全年和DHQ管理四次，在每个季节（秋季，冬季，春季和夏季）的显着差异，观察到30，29，30，和31营养素的男性和21，28，30，和31营养素的女性，分别。Pearson相关系数的DR和DHQ的能量调整摄入量的42种营养素显示显着的季节间差异，男性11种营养素和女性13种营养素。特别是，男性春季的脂肪、单不饱和脂肪、多不饱和脂肪、n-6多不饱和脂肪、α-亚麻酸和胆固醇以及夏季的隐黄质的相关系数，女性春季和夏季的脂肪、饱和脂肪和单不饱和脂肪以及夏季的维生素B1和铁的相关系数因季节性而显着改变。DHQ估计的平均营养摄入量随季节而变化，表明将DHQ估计的营养摄入量视为年平均摄入量可能存在问题。相反，季节性对DHQ排名能力的影响相对较小，因此，无论季节如何，使用DHQ按营养摄入量对个体进行排名对于流行病学研究是可以接受的。
We examined the effect of seasonality on the validity (ability to estimate the mean intake of a group and ranking ability) of nutrient intakes estimated with a comprehensive self-administered diet history questionnaire (DHQ) developed for the assessment of Japanese diets during the preceding one month, using semi-weighed dietary records (DRs) as a reference method. This study was conducted in three areas in Japan (Osaka, Nagano, and Tottori). The study population included 92 Japanese men aged 32–76 years and 92 Japanese women aged 31–69 years (30 from Osaka, 31 from Nagano, and 31 from Tottori for each sex). A DHQ and a four-day DR were completed four times at 3-month intervals, once per season. The effect of seasonality was examined by the level of agreement among seasons using mean nutrient intake and correlation coefficients. Significant differences in estimated energy-adjusted intakes of 42 selected nutrients between the average of DRs administered 16 times throughout a year and that of the DHQ administered four times in each season (fall, winter, spring, and summer) were observed for 30, 29, 30, and 31 nutrients for men and 21, 28, 30, and 31 nutrients for women, respectively. Pearson correlation coefficients between the DRs and the DHQs for energy-adjusted intakes of the 42 nutrients showed significant inter-season differences in 11 nutrients for men and 13 nutrients for women. Particularly, correlation coefficients of fat, monounsaturated fat, polyunsaturated fat, n-6 polyunsaturated fat, α-linolenic acid, and cholesterol in spring and cryptoxanthin in summer for men, and fat, saturated fat, and monounsaturated fat in spring and summer and thiamin and iron in summer for women were markedly altered by seasonality. Mean nutrient intake estimated by the DHQ varied by season, indicating that any consideration of nutrient intake estimated by the DHQ as a yearly average intake may be problematic. In contrast, the effect of seasonality on the ranking ability of the DHQ was relatively small, and thus the use of a DHQ to rank individuals by nutrient intake is acceptable for epidemiological studies, regardless of season.
