Abstract

Eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) intakes during pregnancy affect fetal development and maternal mental health; therefore, an accurate assessment of EPA and DHA intakes is required. We hypothesized that a self-administered diet history questionnaire (DHQ) that was developed for non-pregnant adults could be used for estimating EPA and DHA intakes in pregnant Japanese women; thus, we evaluated the validity and reproducibility of the DHQ during pregnancy. We recruited 262 healthy participants with singleton pregnancies during their second trimester at a university hospital in Tokyo between June 2010 and July 2011. Plasma concentrations of EPA and DHA were measured as reference values. Fifty-eight women completed the DHQ twice, within a 4- to 5-week period to assess the reproducibility of the results. Among the participants without pregnancy-associated nausea (n = 180), significantly positive correlations were observed between energy-adjusted intakes and plasma concentrations of EPA (rs = 0.388), DHA (rs = 0.264), and EPA + DHA (rs = 0.328). More than 60% of the participants without nausea fell into the same or adjacent quintiles according to energy-adjusted intakes and plasma concentrations of EPA, DHA, and EPA + DHA. Meanwhile, among the participants with nausea, a low correlation for EPA and no correlation for DHA and EPA + DHA were found. Intraclass correlation coefficients for the 2-time DHQ measurements were 0.691 (EPA) and 0.663 (DHA). The results indicate that the DHQ has an acceptable level of validity and reproducibility for assessing EPA, DHA, and EPA + DHA intakes in pregnant Japanese women without nausea.
