Docosahexaenoic acid (DHA) is indispensable to ensure proper development of the fetal central nervous system and pregnancy duration. Daily intake of DHA should be at least 100 mg higher as compared to the pre-pregnancy values.
The aim of the study was to evaluate DHA intake during pregnancy and compare it to the current recommendations.
A total of 100 pregnant women presenting for labor at the Department of Obstetrics, Gynecology and Oncology, Medical University of Warsaw, were included in the study. DHA intake from the following sources: fish and eggs, and DHA preparations collected based on the questionnaire was investigated.
Low dietary DHA intake (median: 60 mg/day) was observed. The values were only slightly higher (median: 90 mg/day) after DHA preparations were taken into consideration because only 28% of the pregnant women used DHA preparations. Overall, 92% of the subjects consumed <200 mg of DHA a day, which was the result of insufficient fish consumption (mean: 15 g/day). Only 10% of the respondents ate fish twice a week, in which case the DHA dietary intake was statistically significantly higher (median: 160 mg/day) (p=0.0232). Total median dietary DHA and EPA intake in the study population was 79 mg/day.
The diet of pregnant women is largely deficient as far as DHA intake is concerned. Importantly, it is not possible to comply with current recommendations without dietary supplementation.
二十二碳六烯酸（DHA）对于确保胎儿中枢神经系统的正常发育和孕期时长必不可少。与孕前水平相比，孕期每日DHA摄入量应至少高出100毫克。
本研究旨在评估孕期DHA摄入量，并将其与当前建议量进行比较。
共有100名在华沙医科大学妇产科与肿瘤科分娩的孕妇纳入本研究。基于问卷调查了从鱼类和蛋类等来源以及DHA制剂中摄入的DHA量。
观察到膳食中DHA摄入量较低（中位数：60毫克/天）。将DHA制剂考虑在内后，该值仅略高（中位数：90毫克/天），因为只有28%的孕妇使用了DHA制剂。总体而言，92%的受试者每天摄入的DHA<200毫克，这是鱼类消费量不足（平均：15克/天）的结果。只有10%的受访者每周吃鱼两次，在这种情况下，膳食中DHA摄入量在统计学上显著更高（中位数：160毫克/天）（p=0.0232）。研究人群中膳食DHA和EPA的总中位数摄入量为79毫克/天。
就DHA摄入量而言，孕妇的饮食在很大程度上存在不足。重要的是，不通过膳食补充就无法符合当前的建议。
