摘　　要：【目的】研究中国两种不同膳食模式地区膳食脂肪酸(fatty acid,FA)含量的差异,并探讨这种差异对母初乳脂肪酸组成的影响。【方法】对传统内陆膳食(常州)和海洋膳食(温州)地区孕晚期孕妇进行7d膳食调查,根据《2002中国食物成份数据》中的食物脂肪酸含量数据计算出膳食脂肪酸含量;并通过随访这些孕妇收集5d母初乳样本,采用高效毛细气相色谱分析技术检测5d母初乳的脂肪酸组成。【结果】常州与温州两地孕母摄入的膳食种类存在差异,温州地区孕母摄入的海洋食品远大于常州地区。常州地区孕母膳食脂肪酸中亚油酸(linoleic acid,LA)和α-亚麻酸(α-linolenic acid,ALA)含量均高于温州地区;而二十二碳六烯酸(docosahexaenoic acid,DHA)和二十碳五烯酸(eicosap-entaenoic acid,EPA)含量均低于温州地区;花生四稀酸(arachidonic acid,AA)含量则未见显著差异。两地膳食脂肪酸组成中LA、ALA、AA以及DHA的差异同样反应在5d母初乳中,但两地5d母初乳中的EPA含量差异无显著性。【结论】膳食模式不同的两个地区,其孕母的膳食脂肪酸含量存在差异,且这种差异可在母初乳脂肪酸组成中得到体现。[Objective] To investigate the influence of two different dietary patterns on maternal fatty acid （FA） intake and composition of colostrums. [Methods] A 7-day dietary record was completed by women in their last trimester of pregnancy from Changzhou, Jiangsu province （inland area） and Wenzhou, Zhejiang province （coastal area）, China. The FA composition in maternal diet was calculated using the 2002 Chinese food composition database. Breast milk samples were collected on day 5 and their FA composition was analyzed by capillary gas-liquid chromatography. [Results] There were significant differences in maternal dietary intake of LC-PUFA in these two areas, largely due to the higher intake of sea food in Wenzhou. Among mothers in Changzhou, linoleic acid （LA） and α-linolenic acid （ALA） intakes were higher, while docosahexaenoic acid （DHA） and eicosapentaenoic acid （EPA） intakes were lower than mothers in Wenzhou. There were no significant differences of arachidonic acid （AA） in the maternal diet between these areas. The same differences of LA, ALA, AA and DHA in maternal diet could be seen in breast milk on day 5, but no significant differences were observed between sites in milk EPA content. [Conclusions] There are significant differences in maternal intakes of FAs depending on their dietary habits and these dietary differences appear to influence the composition of breast milk. This variation could have an important influence on child growth and development.
