摘要
目的建立早期母乳喂养影响因素的预测列线图,并验证其效能。方法选取2017年1月至2018年12月于新疆维吾尔自治区人民医院生产的432例孕妇作为研究对象。将其设为建模组,并根据是否进行早期母乳喂养分为早期喂养组(n=143)及对照组(n=289)。另选取同期于新疆维吾尔自治区人民医院生产的121例孕妇设为验证组。比较建模组及验证组的基线资料,并比较早期喂养组及对照组的产时因素、新生儿特征及母婴接触时间,采用Logistic回归分析影响早期母乳喂养的相关因素,使用R软件建立影响因素的列线图预测模型,并验证其效能。结果早期喂养组的产程、产时并发症、产后抑郁自评量表(SDS)、焦虑自评量表(SAS)评分、首次母婴接触时间及进入NICU患儿例数明显低于对照组,新生儿体重、Apgar评分及即刻母婴接触例数明显高于对照组,差异具有统计学意义(P<0.05);早期喂养组及对照组的新生儿性别情况比较,差异无统计学意义(χ~2=0.001,P=0.965);多因素Logistic回归分析结果显示,长产程、无即刻母婴接触、首次母婴接触时间过长及高SDS评分均是影响早期母乳喂养的危险因素(OR=1.890、79.647、13.354、1.105,P<0.05),而无产时并发症、高新生儿体重及Apgar评分则是影响早期母乳喂养的保护因素(OR=0.007、0.597、0.501,P<0.05),列线图预测早期母乳喂养发生的一致性指数(C-index)为0.913(95%CI 0.865~0.952)。结论低产程、无产时并发症、短首次母婴接触时间等因素构建的列线图可有效预测早期母乳喂养,并具有较好的应用价值。
Objective To establish a predictive nomogram of the factors affecting early breastfeeding and verify its effectiveness.Methods 432 pregnant women who gave birth in the People's Hospital of Xinjiang Uygur Autonomous Region from January 2017 to December 2018 were selected as modeling group,while another 121 preg-nant women as the validation group.The modeling group were divided into early feeding group(n=143)and con-trol group(n=289)according to whether early breastfeeding was performed.Baseline data of the modeling group and the validation group were compared,and maternal factors,neonatal characteristics and mother-infant contact time of the early feeding group and the control group were compared.Logistic regression was used to analyze the re-lated factors affecting early breastfeeding,and R software was used to establish the prediction model of the influen-cing factors and verify its effectiveness.Results In the early feeding group,the delivery time,postpartum compli-cations,postpartum SDS,SAS scores,time of first mother-infant contact between mother and child,and children who entered the NICU were significantly lower than those in the control group,while the weight of the newborn,the Apgar score,and immediate mother-infant contact were significantly higher than those of the control Group(P<0.05);there was no significant difference in sex between the two groups of newborns(χ2=0.001,P=0.965);the results of multivariate logistic regression analysis showed that the long-term labor,immediate mother-no-infant con-tact,and first mother-infant contact excessive time and high SDS scores are risk factors that affect early breastfeeding(OR=1.890、79.647、13.354、1.105,P<0.05),while no birth complications,high newborn weight,and Apgar scores were the protective factors affect early breastfeeding(OR=0.007、0.597、0.501,P<0.05).The C-index of the nomogram predicting the occurrence of early breastfeeding was 0.913(95%CI 0.865~0.952).Conclusions The line graphs constructed by factors such as shorter duration of birth,no d
