Alcohol consumption has a relatively large impact on energy intake in drinkers, and several studies reported different dietary habits from non-drinkers. However, few studies have investigated the influence of alcohol consumption on the validity of the Food Frequency Questionnaire (FFQ). To investigate its influence, we conducted a validity test in a population with high alcohol consumption.
The study subjects were 66 residents living on an island in the south-western part of Japan. We conducted the FFQ and 12-day-weighed dietary records (12d-WDRs) in each 3 day of each 4 season. We calculated Pearson correlation coefficients (CCs) and agreement rates according to quartile classification after adjusting for energy.
The intake energy (kcal) estimated from 12d-WDRs and FFQ was 1,641 and 1,534 in women, and 2,093 and 1,979 in men, respectively. The cumulative percentage contribution of the alcohol energy was 6.7% in men. De-attenuated, log-transformed Pearson's median CCs between the nutrients quantified with the 12d-WDRs and FFQ were 0.51 in women and 0.38 in men. The CCs for carbohydrate and saturated fatty acids intake of men were lower than those in the previous Tokai study using the same FFQ. The findings in agreement rates were consistent with the Tokai study.
This study suggested that the FFQ can be used for epidemiological studies using categorical comparisons in this population, although the underestimation of carbohydrates and other nutrients in the FFQ should be taken into consideration.
饮酒对饮酒者的能量摄入有较大影响，多项研究报告了饮酒者与非饮酒者不同的饮食习惯。然而，很少有研究调查饮酒对食物频率问卷（FFQ）有效性的影响。为了研究其影响，我们在高饮酒量人群中进行了一项有效性测试。
研究对象为居住在日本西南部一个岛屿上的66名居民。我们在四个季节的每个季节的每三天分别进行了FFQ和为期12天的称重饮食记录（12d-WDRs）。在对能量进行调整后，我们根据四分位数分类计算了Pearson相关系数（CCs）和一致率。
根据12d-WDRs和FFQ估算的女性摄入能量（千卡）分别为1641和1534，男性分别为2093和1979。男性酒精能量的累积百分比贡献为6.7%。对12d-WDRs和FFQ量化的营养素进行去衰减对数转换后的Pearson中位数CCs，女性为0.51，男性为0.38。男性碳水化合物和饱和脂肪酸摄入量的CCs低于之前使用相同FFQ的东海地区研究中的结果。一致率的结果与东海地区研究一致。
本研究表明，尽管应考虑FFQ对碳水化合物和其他营养素的低估，但FFQ可用于该人群中使用分类比较的流行病学研究。
