Omega-3脂肪酸在胎儿生长发育过程中起着至关重要的作用，增加摄入与改善母胎结局有关。西方饮食中Omega-3脂肪酸的摄入量较低，社会经济因素对孕妇和育龄妇女Omega-3脂肪酸摄入量的影响尚未见报道。我们使用2003-2012年国家健康和营养检查调查（NHANES）周期来评估育龄妇女omega-3脂肪酸摄入量与社会经济因素之间的关系。在7266名符合条件的参与者中，6478名是育龄妇女，而788名在调查时被确定为怀孕。人群EPA+DHA的平均摄入量为89.0 mg，孕妇和非孕妇之间无显著差异。通过调整混杂因素的单变量和多变量分析，ω -3脂肪酸摄入量与贫困收入比、种族和受教育程度显著相关。我们的研究结果表明，omega-3脂肪酸的摄入在美国孕妇和育龄妇女中是一个值得关注的问题，而社会经济条件较差的人群更容易出现潜在的缺乏。在这些人群中增加omega-3脂肪酸摄入量的策略可能有改善母婴健康结果的潜力。
Omega-3 fatty acids play critical roles during fetal growth and development with increased intakes associated with improved maternal-fetal outcomes. Omega-3 fatty acid intake in Western diets is low, and the impact of socioeconomic factors on omega-3 fatty acid intake in pregnant women and women of childbearing age has not been reported. We used the National Health and Nutrition Examination Survey (NHANES) cycles 2003-2012 to assess the relationship between omega-3 fatty acid intake and socioeconomic factors in women of childbearing age. Out of 7266 eligible participants, 6478 were women of childbearing age, while 788 were identified as pregnant at the time of the survey. Mean EPA+DHA intake of the population was 89.0 mg with no significant difference between pregnant and non-pregnant women. By univariate and multivariate analyses adjusting for confounders, omega-3 fatty acid intake was significantly associated with poverty-to-income ratio, race, and educational attainment. Our results demonstrate that omega-3 fatty acid intake is a concern in pregnant women and women of childbearing age in the United States, and that socioeconomically disadvantaged populations are more susceptible to potential deficiencies. Strategies to increase omega-3 fatty acid intake in these populations could have the potential to improve maternal and infant health outcomes.
