【摘要】 目的通过检测城市及农村乳母乳汁维生素B1、维生素B2、维生素B6和烟酸含量,了解乳母及婴幼儿的营养水平,为改善乳母及其婴儿的维生素营养状况提供科学依据。方法 2012年4—7月,选择山东省城乡母乳喂养的身体健康乳母及其婴幼儿为调查对象,共92对,其中某城市34对,某农村58对,收集以上健康乳母的乳汁及乳母和婴幼儿尿液。检测母乳维生素B1、维生素B2、维生素B6和烟酸的含量以及乳母及其婴幼儿尿液中维生素B1、维生素B2和烟酸含量。结果城市乳母乳汁维生素B2、维生素B6和烟酸含量明显高于农村乳母。检测分析显示城市乳母乳汁维生素B2为149.77μg/100 g,明显高于农村乳母的85.09μg/100 g(P<0.05);维生素B6和烟酸含量分别为15.29μg/100 g、40.83μg/100 g,也分别高于农村乳母乳汁含量(6.69和24.48μg/100 g)(P<0.05);然而,城市和农村乳母乳汁维生素B1分别为5.54μg/100 g和4.80μg/100 g,未见明显差异;尿液分析结果显示城市乳母及婴幼儿机体维生素B2和烟酸显著高于农村地区(P<0.05);而维生素B1水平农村婴幼儿高于城市(P<0.05);乳母维生素B1水平城乡无显著差异。城市乳母维生素B1、维生素B2和烟酸不足检出率分别为23.5%、32.3%和17.6%,农村乳母分别为29.3%、82.8%和53.4%;城市婴幼儿维生素B1、维生素B2和烟酸不足率为2.9%、2.9%和11.8%;农村婴幼儿分别为5.1%、51.8%和25.8%。结论城市和农村乳母机体维生素B1不足率较高,乳汁维生素B1含量较低;而农村乳母和婴幼儿维生素B2和烟酸不足率明显高于城市。
【Abstract】 Objective To understand the nutritional level of lactating mothers and infant by detecting the content of the vitamin B1,vitamin B2,vitamin B6,nicotinic of milk of urban and rural areas and to provide the basis for improving vitamin nutritional status oflactating women and their babies. Methods Totally 92 pairs of breastfeeding healthy mothers and their children in Shandong Province were selected. 34 pairs were in a urban area and 58 pairs were in a rural area. Collect the milk of selected lactating mothers and the urine of the lactating mothers and their children. Detect the content of vitamin B1, vitamin B2,vitamin B6,nicotinic of milk of lactating mothers and the content of vitamin B1,vitamin B2,nicotinic of urine of lactating mothers and their children. Results The content of vitamin B2,vitamin B6and niacin of milk of urban lactating mothers were significantly higher than that of rural lactating mothers. The results of detection showed the vitamin B2of milk of urban lactating mothers was 149. 77 μg/100 g,which was significantly higher than that of rural women in 85. 09 μg/100 g(P < 0. 05). Vitamin B6 and niacin contents were 15. 29 μg/100 g,40. 83 μg/100 g,which were also higher than that in rural lactating milk(6. 69 μg/100 g and 24. 48 μg/100 g)(All values P < 0. 05). However,vitamin B1of milk of urban and rural lactating mothers were 5. 54 μg/100 g and 4. 80 μg/100 g respectively,which had no significant difference. Urine analysis showed vitamin B2and niacin of urban mothers and children were significantly higher than that in rural area(P < 0. 05). But the level of vitamin B1of rural children was higher than that of urban children(P < 0. 05). There was no significant difference in the vitamin B1between urban and rural mothers. The insufficient percentages of vitamin B1,vitamin B2. niacin in urban mothers was 23. 5%,32. 3% and 17. 6%,and that in rural mothers were 29. 3%, 82. 8% and 53. 4%. The deficiency percentage of vitamin B1,vitamin B2,niacin in urban children were 2. 9%,2. 9% and 11. 8%,and that in rural children were 5. 1%,51. 8% and 25. 8%. Conclusion The insufficient percentage of vitamin B1in urban and rural mothers was high and the content of vitamin B1of milk was low. While the insufficient percentage of vitamin B2,niacin of rural lactating mothers and children were higher than that of urban mothers and children.
