摘　　要：目的分析我国城乡不同泌乳阶段母乳中钙、磷、镁、钾、钠的含量,为制定其适宜摄入量提供科学依据。方法数据来源于中国母乳成分数据库研究,该项目为横断面调查,于2011年11月到2013年6月在我国11个省和地区收集产后0d~330 d乳母的母乳样本,从来自不同哺乳期的健康乳母的6481份人乳样本中抽样1579份样品,采用微波消解电感耦合等离子质谱法(ICP-MS)测定母乳中钙、磷、镁、钾、钠的含量。结果初乳、过渡乳、早期成熟乳和晚期成熟乳中钙含量分别为(278.3±63.1)、(289.3±69.9)、(270.7±65.9)、(241.0±58.6)mg/kg,磷含量分别为(157.6±50.4)、(176.7±53.2)、(144.2±41.6)、(128.0±31.5)mg/kg,镁含量分别为(27.9±5.9)、(24.8±4.8)、(25.0±5.3)、(26.1±5.6)mg/kg,钾含量分别为(624.2±116.4)、(575.7±95.7)、(490.0±86.8)、(428.3±65.1)mg/kg,钠含量分别为(370.6±204.7)、(242.2±123.1)、(128.3±69.2)、(88.6±44.1)mg/kg。结论不同泌乳阶段母乳中钙、磷、镁、钾、钠均存在差异,整体上随哺乳期延长呈降低趋势。Objective To analyze the concentrations of calcium,phosphorus,magnesium,potassium and sodium in breast milk samples from urban and rural Chinese women at different lactation stages.Methods The data were from a human milk composition database in China.A cross-sectional survey was conducted to collect milk samples from lactating mothers 0-330 days postpartum between November 2011 and June 2013 in 11 provinces and regions of China.A total of 1579 samples of human milk were sampled from 6481 healthy lactating mothers at different lactation stages.The concentrations of calcium,phosphorus,magnesium,potassium and sodium in breast milk were analyzed using inductively coupled plasma mass spectrometry(ICP-MS)with microwave digestion.Results In colostrum,transitional milk,early mature milk and late mature milk,the concentrations were(278.3±63.1),(289.3±69.9),(270.7±65.9),(241.0±58.6)mg/kg respectively for calcium,(157.6±50.4),(176.7±53.2),(144.2±41.6),(128.0±31.5)mg/kg for phosphorus,(27.9±5.9),(24.8±4.8),(25.0±5.3),(26.1±5.6)mg/kg for magnesium,(624.2±116.4),(575.7±95.7),(490.0±86.8),(428.3±65.1)mg/kg for potassium,(370.6±204.7),(242.2±123.1),(128.3±69.2),(88.6±44.1)mg/kg for sodium.Conclusion The concentrations of calcium,phosphorus,magnesium,potassium and sodium of breast milk vary between different lactation stages.
