Abstract: The unified dietary reference intakes (DRIs) have been introduced in China. Nevertheless, there are wide regional variations in dietary intake and nutritional status of lactating mothers across the country, which are associated with geographic environment, life style, socio-economic and culture factors, education level, etc even within the same region. The nutritional status of both lactating mothers and their infants is influenced by maternal dietary intake. Hence, understanding of dietary intake and nutritional status of lactating mothers from different regions of China is meaningful for formulating appropriate guidelines.

Key words: lactating mother; dietary nutrition; survey; variation
