为了分析中国代表性地区健康乳母的母乳寡糖因地区、泌乳时间和血型基因型受到的影响,探究中国母乳寡糖的构成特征,采用纵向队列研究方法采集我国东西南北6个城市、109名健康母亲、3个泌乳阶段的母乳样本,利用超高效液相色谱-串联三重四极杆质谱分析23种母乳寡糖的质量浓度,并对母乳血型基因型归属状态进行分析。结果表明,昆明、济南和深圳的总母乳寡糖质量浓度和总岩藻糖基中性寡糖质量浓度显著高于北京、包头和西宁,其中包头地区母乳的3-岩藻糖基乳糖(3-fucosyllactose,3-FL)、二岩藻糖基乳糖(lactodifucotetraose,LdFT)和乳糖-n-二岩藻糖基新六糖II(lacto-n-neodifucohexaose II,Lnn dFH-II)质量浓度分别显著低于深圳、济南和北京;8种中性寡糖和4种酸性寡糖随泌乳时间延长呈现显著降低趋势;3-FL含量随泌乳时间延长呈现显著上升,LdFT和Lnn dFH-II也随泌乳时间延长呈上升趋势,但差异不显著;2种单岩藻糖基六糖在1月龄成熟乳时质量浓度达到最高,之后持平或者略降低;以寡糖类型推测的血型基因型分型发现,各城市乳母均以se+Le+为主,但该类型母乳中除了乳糖-n-二岩藻糖基六糖II(lacto-n-difucohexaose II,LndFH-II)、LndFH-I&Lnn dFH-I、6’-唾液酸化乳糖和唾液酸化-乳糖-四糖c质量浓度比其他血型基因型高以外,其他18种寡糖质量浓度均低于其他血型基因型。本研究揭示了地区、泌乳阶段和乳母血型基因型造成了母乳寡糖组成和含量的差异,可为生命早期婴幼儿营养摄入中母乳寡糖的精准化提供科学理论指导。

Background: Kangaroo m.ther Care is a sim.le safe m.thod used to care for low-birth-weight babies. Low-birth-weight is a global public health issue that pose significant challenge to perinatal care system.. Globally, com.lications due to low-birth-weight are the leading cause of neonatal m.rtality, resulting in an estim.ted 1 m.llion deaths annually. Kangaroo m.ther Care (Km.) is a low-cost m.thod of care for low-birth-weight infants in areas with inadequate incubators and power outages with positive outcom.s. Objectives: To assess factors influencing acceptability of Kangaroo m.ther Care (Km.) in nICU at Arthur davison Children’s Hospital in ndola, Zam.ia. m.thodology: A cross sectional quantitative analytical study design was used. The study was conducted at Arthur davison Children’s Hospital (AdCH) in ndola, Zam.ia. The purposive sam.ling m.thod was used to select the study participants and a total of 129 m.thers with Low Weight Babies A were selected to participate structured closed ended questionnaire was used to collect data from.the participants using an interview. data was analyzed using a statistical Package for social scientists (sPss) software version 26. Cross tabulations were done to determ.ne association of variables using a Chi square (xsup>2sup>) test at 95% confidence interval and were assum.tions where not m.t, fishers exact test was used. m.ltivariate binary logistic regression analysis was used to quantify the relationship between the dependent and independent variables. Results: m.st of the respondents had m.le babies 77%, 69% of the babies weighed 1000 g - 1400 g, m.jority 79% had norm.l delivery, 71% of the respondents were m.ltigravida and m.st of the respondents 79% were m.rried. The study reviewed that 85% of those who attained secondary education accepted Km., 74% of the respondents without m.nthly incom. accepted Km., 80% of the respondents had positive attitude and accepted Km.. 82% of the respondents who had positive perception accep
