摘　　要：目的分析我国4城市乳母能量和各种营养素的摄入量,探究其与纯母乳喂养婴儿身长别体重的关系。方法通过问卷调查、身体测量和血液生化检测收集我国4城市64对纯母乳喂养母婴对乳母膳食等数据,评价乳母能量和各种营养素摄入与婴儿身长别体重,应用有序多分类Logistic回归分析模型分析二者的关系。结果我国4城市乳母硒、维生素B2和叶酸摄入不足情况较为普遍,乳母膳食铁摄入不足(OR=0.005,95%CI:0.000~0.165,P=0.003)及血清维生素D缺乏(OR=0.019,95%CI:0.003~0.125,P<0.001)的婴儿身长别体重水平更低(P<0.05)。结论我国4城市纯母乳喂养婴儿的乳母多种营养素摄入未达DRIs,婴儿身长别体重与乳母膳食铁摄入和血清维生素D水平有关。提示关注妊娠期铁和哺乳期维生素D营养状况,确保妊娠期和哺乳期妇女的膳食营养摄入量保持平衡,促进婴儿生长发育和母婴健康。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.
