title: [Comparative analysis of four kinds of vitamin B of milk of lactating mothers and maternal and infant nutritional status in Chinese urban and rural areas].
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 of lactating 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 B6 and niacin of milk of urban lactating mothers were significantly higher than that of rural lactating mothers. The results of detection showed the vitamin B2 of milk of urban lactating mothers was 149.77 microg/100 g, which was significantly higher than that of rural women in 85.09 microg/100 g (P < 0.05). Vitamin B6 and niacin contents were 15.29 microg/100 g, 40.83 microg/100 g, which were also higher than that in rural lactating milk (6.69 microg/100 g and 24.48 microg/100 g) (All values P < 0.05). However, vitamin B1 of milk of urban and rural lactating mothers were 5.54 microg/100 g and 4.80 microg/100 g respectively, which had no significant difference. Urine analysis showed vitamin B2 and niacin of urban mothers and children were significantly higher than that in rural area (P < 0.05). But the level of vitamin B1 of rural children was higher than that of urban children (P < 0.05). There was no significant difference in the vitamin B1 between 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%.
  
  
  CONCLUSIONS
  The insufficient percentage of vitamin B1 in urban and rural mothers was high and the content of vitamin B1 of 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.
