[Nutritional status and influencing factors of breast milk vitamin A among lactating women in three regions of Chin].

The prevalence of breast milk VitA deficiency among the Chinese lactating women was 41.9%, suggesting that breast milk VitA deficiency in lactating women and inadequate VitA intake for infants were common in China. The women in Baotou, low educational status and low fish intake increased the risk of breast milk VitA deficiency, suggesting that attention should be paid to the nutritional status of lactating women in underdeveloped regions such as inland region, and education for health should be enhanced and food containing VitA such as fish intake should be increased.
