Correlation between dietary nutrient intakes of lactating women and weight for height of exclusive breast-fed infants in urban areas in China
Objective To describe the energy and nutrient intakes of lactating women in 4 urban areas of China,and develop the relationship between them and the weight for length of exclusive breast-fed infants.Methods The dietary of lactating women,body and blood biochemical data of 64 exclusive breast-fed women-infant pairs in 4 urban areas in China were collected using questionnaires,body measurements and blood test.The energy and nutrient intakes of lactating women and the weight for height of infants were calculated and analyzed,and the relationship between them was estimated by using the ordinal multiple classification Logistic regression analysis model.Results Insufficient intake of maternal selenium,vitamin B2 and folic acid is common in 4 cities in China.The Weight for height of infants whose lactating women had low dietary intake of Fe(OR=0.005,95％CI:0.000-0.165,P=0.003)and deficiency of serum Vitamin D(OR=0.019,95％CI:0.003-0.125,P＜0.001)was lower(P＜0.05).Conclusion Multi-nutrient intakes of lactating women in 4 urban areas in China is lower than that recommended by Chinese DRIs,and the weight for height of infants is associated with dietary iron intake and serum vitamin D levels of lactating women.It is suggested to pay attention to the nutritional status of iron during pregnancy and vitamin D during lactation,ensure that the dietary nutritional intake of pregnant and lactating women remains balanced,and promote the growth and development of infants and maternal health.
