目的 构建母婴分离产妇纯母乳喂养失败的风险预测列线图模型。方法 选取赣州市某三级甲等医院2020年2月至2022年6月住院的母婴分离产妇及患儿共312对，对其临床资料进行回顾性分析，分为建模群（n=208）和验证群（n=104）。再将建模群按纯母乳喂养情况分为成功组（n=86）和失败组（n=122），探讨纯母乳喂养失败的危险因素，绘制并验证风险预测列线图模型。结果 纯母乳喂养失败率为58.01%(181/312)；母婴分离时间、产妇母乳喂养核心知识不了解、产妇乳头内陷、围产期并发症、产妇食欲下降、遵医嘱乳房刺激、患乳腺炎等均是纯母乳喂养失败的影响因素（均P＜0.05）。结论 构建的风险预测列线图模型效能良好，可有效预测母婴分离产妇纯母乳喂养失败的风险因素，值得推广应用。

Objective To construct a nomograph model for predicting the risk of failure of exclusive breastfeeding in mothers due to mother-child separation.Methods A retrospective analysis was made on 312 pairs of clinical data of hospitalized infants with their mothers admitted to a tertiary A hospital in Ganzhou from February 2020 to June 2022.These pair of infants and their mothers were divided into modeling group (n=208) and verification group (n=104).The modeling group was divided into success group (n=86) and failure group (n=122) according to the situation of exclusive breastfeeding.The risk factors of exclusive breastfeeding failure were explored,and the risk prediction nomograph model was drawn and its effectiveness was verified.Results The failure rate of exclusive breast-feeding was 58.01%.The separation time between mother and infant,lack of understanding of core knowledge of breastfeeding,inverted nipples,perinatal complications,decreased appetite,breast stimulation following medical advice,and mastitis were all influencing factors for the failure of pure breastfeeding (all P＜0.05).Conclusions The constructed model has a good predictive effect and can effectively predict the risk factors of pure breastfeeding failure due to mother-child separation,and is worth promoting and applying.
