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

摘要： 目前中国居民膳食营养参考摄入量在各地区按照统一标准施行。然而中国地区差异大，乳母膳食营养有一定的差异，即使是在同一地区，乳母膳食营养也受到地理环境、生活习惯、社会经济和文化、教育水平等的影响。乳母膳食影响母婴营养状况。了解和掌握不同地区乳母膳食摄入特点和营养情况，对指导饮食摄入量有重要意义。
