【摘要】：目的调查中国内陆地区孕妇孕晚期膳食模式与其过渡乳中脂肪酸构成的关系。方法选取靠近淡水河湖(江苏句容)和远离河湖(河北徐水)的内陆地区各一处,每地区募集孕晚期孕妇40位,调查其孕晚期膳食消费情况及其过渡乳脂肪酸构成。结果两地区孕妇海鱼消费频次均低于1次/周,句容地区孕妇消费菜籽油显著高于徐水地区(P0.05)。两地区乳母每100 g过渡乳中总脂质含量分别为(4.39±1.18)和(3.92±1.47)g(P=0.11),DHA含量分别为(0.46±0.20)%和(0.29±0.09)%(P0.05)。菜籽油摄入量与过渡乳中DHA百分含量显著相关(r=0.362,P0.05)。结论两地区孕产妇过渡乳脂肪酸构成差异可能由其膳食模式差异所致。充分摄入n-3长链多不饱和脂肪酸的前体(如α亚麻酸)在一定程度上可有效代偿其摄入的不足。
[Abstract]:Objective to investigate the relationship between dietary pattern in late pregnancy and fatty acid composition in transitional milk of pregnant women in inland areas of China. 40 pregnant women were recruited in each area to investigate their dietary consumption and the composition of transitional milk fatty acids. Results the frequency of sea fish consumption of pregnant women in the two areas was less than once a week. The consumption of rapeseed oil by pregnant women in Jurong area was significantly higher than that in Xushui area (P 0.05). The total lipid content per 100g transition milk of lactating mothers in the two areas was 4.39 卤1.18) and (. (3.92 卤1.47). The content of DHA was 0.46 卤0.20% and 0.29 卤0.09%, respectively. There was a significant correlation between the intake of rapeseed oil and the content of DHA in transition milk (P < 0.05). Ru 0.362. Conclusion the difference of fatty acid composition between the two regions may be due to the difference in dietary pattern. Adequate intake of n-3 long chain polyunsaturated fatty acid precursors (such as 伪 linolenic acid). To a certain extent, it can effectively compensate for its insufficient intake.

【正文快照】： 二十二碳六烯酸(DHA)和花生碳四烯酸(ARA)是分别属于n-3和n-6两系的长链多不饱和脂肪酸(LCPUFA),它们在促进胎儿/新生儿的神经系统发育方面均发挥重要功效[1]。由于新生儿自身合成LCPUFA的能力较弱[2],且较之其他来源的LCPUFA,新生儿/婴儿对于母乳来源LCPUFA的利用显得更加高
