Erratum: Estimated Dietary Intakes of Arachidonic Acid and Docosahexaenoic Acid in Infants and Young Children Living in Developing Countries

Background/Aims: There are only few data on dietary arachidonic acid (ARA) and docosahexaenoic acid (DHA) intake in infants from developing countries, and current global recommendations on intake during early life may not reflect the needs of the world's most vulnerable infants. The aim of the study was to provide estimates of intake of ARA and DHA in infants and young children aged 6-36 months who live in developing countries. Methods: FAO Food Balance Sheets and fatty acid composition data from Australian food composition tables were utilized to generate mean per capita intake estimates for DHA and ARA in developing countries. The median daily intake of DHA and ARA in children age 6-36 months in each country was determined by combining the fatty acid composition of breast milk and complementary foods with the estimated intakes being weighted according to median duration of any breastfeeding. Results: The median daily dietary intake for ARA and DHA across 76 developing countries was 64.0 and 48.9 mg/day, respectively. The lowest complementary food intake of ARA and DHA was present in countries with the lowest gross national income and highest birth rates. Conclusion: Global recommendations on ARA and DHA in early life need to reflect the specific needs of infants and families living in low income countries, and country-specific food policies should address gaps between recommended and achieved intakes.

研究背景与目的：目前关于发展中国家婴幼儿膳食花生四烯酸（arachidonic acid, ARA）与二十二碳六烯酸（docosahexaenoic acid, DHA）摄入情况的研究数据较为匮乏，当前全球针对生命早期该两类营养素摄入的推荐标准，或无法反映全球最弱势婴幼儿群体的真实营养需求。本研究旨在估算发展中国家6至36月龄婴幼儿及低龄儿童的ARA与DHA膳食摄入量。

研究方法：本研究采用FAO食物平衡表以及澳大利亚食物成分表中的脂肪酸组成数据，对发展中国家人均ARA与DHA的平均摄入量进行估算。通过结合母乳与辅食的脂肪酸组成，并依据任意母乳喂养的中位时长对估算摄入量进行加权，从而得到各国6-36月龄儿童每日DHA与ARA摄入量的中位数。

研究结果：本次研究覆盖76个发展中国家，其婴幼儿的ARA与DHA日均膳食摄入中位数分别为64.0mg/天和48.9mg/天。国民总收入最低、出生率最高的国家，其婴幼儿辅食中ARA与DHA的摄入量也处于最低水平。

研究结论：当前全球针对生命早期ARA与DHA摄入的推荐标准，需充分考虑低收入国家婴幼儿及其家庭的特殊营养需求；各国应制定针对性食物政策，以缩小推荐摄入量与实际摄入量之间的差距。
