摘要
目的:探讨产后妇女母乳喂养持续时间的影响因素,建立回归预测模型。方法:选取2022年12月-2023年12月在本院分娩的产妇262例为研究对象,依据产后6个月内是否行纯母乳喂养分为纯母乳喂养组、非纯母乳喂养组。收集产妇一般人口学资料、相关临床特征,应用多因素logistic回归模型确定产妇产后6个月内纯母乳喂养的独立影响因素,建立回归预测模型,并判定模型拟合优度与预测价值。结果:本研究共发放262份问卷,回收有效问卷254份,有效回收率97.0%。254例产妇中产后6个月内行纯母乳喂养91名,占比35.8%。多因素logistic回归分析显示,就业状况为在职、自觉奶水不足为产妇产后6个月内未行纯母乳喂养的独立危险因素,有母乳喂养经历、家庭成员对母乳喂养支持、母乳喂养知识评分高为独立保护因素(均P<0.05)。依据5项独立影响因素的回归系数建立回归预测模型,Logit(P)=6.878+2.378×就业状况(在职=1,非在职=0)-2.264×母乳喂养经历(有=1,无=0)-1.553×家庭成员对母乳喂养支持状况(支持=1,中性/不支持=0)+2.261×自觉奶水不足(是=1,否=0)-0.482×母乳喂养知识评分(分)。Hosmer-Lemeshow检验显示模型具有良好拟合优度。ROC曲线发现,回归预测模型预测产妇产后6个月内未行纯母乳喂养的曲线下面积为0.949,95%CI为0.925~0.973,约登指数取最大值0.721时,模型最佳预测敏感度为85.3%,特异度为86.8%,准确度为85.8%。结论:本研究构建的回归预测模型对产后妇女母乳喂养持续时间具有良好预测价值,可为临床预测提供依据。
Objective:To explore the influencing factors of the breastfeeding duration of parturients,and to establish a regression prediction model for the duration of breastfeeding of the parturients.Methods:A total of 262 parturients who had given birth in the hospital from December 2022 to December 2023 were selected as the research objects.According to whether exclusive breastfeeding of parturients was performed or not within 6 months after delivery,these parturients were divided into group A(the parturients with exclusive breastfeeding within 6 months after delivery)and group B(the parturients without exclusive breastfeeding within 6 months after delivery).The general demographic data and the related clinical characteristics of the parturients in the two groups were collected.Multivariate logistic regression model was used to determine the independent influencing factors of the exclusive breastfeeding of the parturients within 6 months after delivery,and the regression prediction model was established based on these influencing factors,and the goodness of fit and predictive value of the model were determined.Results:A total of 262 questionnaires were distributed in this study,and 254 valid questionnaires were recovered,with an effective recovery rate of 97.0%.Among 254 parturients,91 parturients were exclusively breastfed within 6 months after delivery,accounting for 35.8%.Multivariate logistic regression analysis showed that the employment status and the conscious lack of breast milk of the parturients were the independent risk factors of their absence of exclusive breastfeeding within 6 months after the delivery.The breastfeeding experience,the support for breastfeeding by the family members and the high score of the breastfeeding knowledge of the parturients were the independent protective factors of their exclusive breastfeeding(all P<0.05).A regression prediction model was established based on the regression coefficients of these five independent influencing factors,Logit(P)=6.878+2.378×employment status(on-the-j
