Abstract: Objective To analyze the mature breast milk composition in Weinan City,and to provide the basis for guiding the work of breastfeeding in this region. Method Healthy lactating women mature breast milk samples were collected using the MIRIS HMA Milk Analyzer ",to detect the macro nutrient content and analyze results and the related factors. Results The subject included 4 317 samples,the composition of fat,proteins,carbohydrates,drymatter,energy were dynamic.The nutritional components of the milk also changed by baby months increasing.The fat and dry matter decreased but the changes were not significantly (P>0.05),proteins and energy were decreased significantly by the month of age (P<0.05).Carbohydrate was increased,but differences were not significant by the month of age (P>0.05). Conclusions The nutrients in breast milk were dynamic changed,relationships of milk composition level and maternal age,infant sex were not obvious,macro nutrient elements in local district mature milk contains,protein,fat,energy content except carbohydrate were higher than results of domestic and foreign areas.
