摘要

摘要 本研究旨在确定血清中二十二碳六烯酸(DHA)和二十碳五烯酸(EPA)水平与孕期膳食摄入量和补充剂使用量之间的关系。这项前瞻性观察研究在日本东京的一家大学医院进行。研究人员向怀孕第二和第三个月的孕妇发放了一份自填式问卷,评估她们在过去一个月中使用 DHA 和 EPA 补充剂的频率,并发放了一份简短的自填式饮食史问卷。采用气相色谱法分析了非空腹血清中的 DHA 和 EPA 水平。使用多重比较分析确定补充剂使用频率与生物标志物之间的差异,使用斯皮尔曼相关系数确定生物标志物与食物组中 DHA 和 EPA 摄入量之间的差异。在 116 名参与者中,有 11 人(9⋅5%)在怀孕的第二个三个月和 18 人(15⋅5%)在怀孕的第三个三个月经常使用补充剂(每周≥5 次)。与从未使用过保健品的孕妇相比,经常使用保健品的孕妇在第二和第三个孕期的血清中 DHA 和 EPA 含量更高。从鱼类和贝类中摄入的 DHA 和 EPA 与第二和第三个孕期的血清 DHA 和 EPA 呈正相关。每周使用补充剂≥5 次以及鱼类和贝类摄入量与高血清 DHA 和 EPA 水平有关。

Association of serum docosahexaenoic acid and eicosapentaenoic acid levels with dietary intakes and supplement use during pregnancy: a prospective observational study
Abstract Abstract This study aimed to determine the association of serum docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) levels with dietary intakes and supplement use during pregnancy. This prospective observational study was conducted at a university hospital in Tokyo, Japan. Participants in their second and third trimesters were given a self-administered questionnaire assessing the frequency of DHA and EPA supplement use in the past month and a brief-type self-administered diet history questionnaire. Non-fasting serum DHA and EPA levels were analysed using gas chromatography. Differences in biomarkers by frequency of supplement use were determined using multiple comparison analyses, and Spearman's correlation coefficient was used to determine biomarkers and DHA and EPA intakes by food group. Of the 116 participants, 11 (9⋅5 %) in the second trimester and 18 (15⋅5 %) in the third trimester regularly used supplements (≥5 times per week). Regular users had higher serum DHA and EPA levels than never users in the second and third trimesters. Dietary DHA and EPA intake from fish and shellfish was positively correlated with serum DHA and EPA in the second and third trimesters. Supplement use ≥5 times per week and fish and shellfish intake were associated with high serum DHA and EPA levels.
