摘要
【目的】 追踪观察孕妇、乳母膳食不同二十二碳六烯酸 (DHA)摄入水平对婴儿早期运动发育和视功能的影响。 【方法】 选取孕 2 4周前妇女 14 6名 ,在孕 ( 2 2± 2 )周、孕 ( 3 8± 2 )周、产后 3月± 2周进行膳食调查。再随机抽取其中 48名母乳喂养婴儿于 2、3个月龄时用中国儿童发展中心 (CDCC)制定的 0～ 3岁婴幼儿智能发育量表进行评价 ,得出智力和运动发育指数 (MDI和PDI) ,婴儿 3个月时测双眼视网膜电图 (electroretinograph ,ERG)。按 3次平均膳食DHA摄入量将孕妇、乳母分成三组 :A组DHA <80mg/d ,14例 ;B组为DHA平均摄入量 80～ 15 9mg/d组 ,2 2例 ;C组为DHA≥ 160mg/d组 ,12例。 【结果】 孕妇、乳母日均DHA摄入量为 ( 10 3 .17± 5 1.43 )mg/d。C组婴儿PDI在 2、3月龄时均显著高于A组 (P <0 .0 5 )。A组婴儿视网膜电图多项指标显著低于其它两组 (P <0 .0 5 )。 【结论】 孕妇、乳母摄入DHA≥
To study the effects of docosahexaenoic acid(DHA) intakes of pregnant and lactating women on the development of neurodevelopmental quotient and visual function in their infants. 146 mothers whose gestation were at (22±2)w were chosen and the dietary intake data were collected for the subjects at (22±2)w of pregnancy, (38±2)w of pregnancy, and 3mo±2w after delivery, respectively. The type and amount of food intakes within three days were recorded. 48 voluntary of them were chosen,and neurodevelopmental quotient evaluation according to Children's Development Center of China(CDCC) were carried out in their babies by breastfeeding at 2mo and 3mo old to obtain the mental development index(MDI) and psycho motor development index(PDI).ERG of both eyes in their babies were tested at three months old. They were divided into three groups according to the average DHA intakes: group A,<80 mg/d( n =14),group B,80～159 mg/d( n =22) and group C,≥160 mg/d( n =12). The average dietary intake of DHA of pregnant and lactating women in Guangzhou was (103.17±51.43) mg/d.Infants’PDI of group C was significantly higher than group A at 2mo and 3mo ( P <0.05).Some indexes of ERG in group B and C were significantly higher than group A ( P <0.05). [Conclusion] Pregnant and lactating women whose DHA intake is over 160 mg/d can improve neurodevelopmental quotient and visual function of their infants by breastfeeding.
