The primary objective is to investigate the related factors of exclusive breastfeeding based on the theory of planned behaviour (TPB) and identify the most influencing factor in first-time mothers at 4 postnatal months.
A cross-sectional study was conducted and 400 first-time mothers at 4 months postnatal were approached.
Data on mothers' breastfeeding knowledge, attitude, subjective norm and practice control were collected at 4 months postnatal based on the TPB. The associations between these four factors and exclusive breastfeeding outcome were analysed using logistic regression and artificial neural network.
Responses were acquired from 272 mothers. Exclusive breastfeeding rate was 34.4% at 4 months. About 66% and 79% mothers stopped breastfeeding their babies partially and absolutely during the first two postnatal months. Results showed that higher scores of breastfeeding knowledge (OR = 1.09, 95% CI = 1.04-1.14), attitude (OR = 1.04, 95% CI = 1.00-1.09), subjective norm (OR = 1.22, 95% CI = 1.11-1.34) and practice control (OR = 1.11, 95% CI = 1.02-1.20) were associated with a higher rate of exclusive breastfeeding. Among the four factors, breastfeeding knowledge was the utmost important factor contributing to exclusive breastfeeding.
Breastfeeding knowledge, attitude, subjective norm and practice control are positively related to exclusive breastfeeding based on the TPB. Future breastfeeding promotion intervention should target these four factors, especially breastfeeding knowledge, and continue for at least two postnatal months.
主要目的是基于计划行为理论（TPB）探究纯母乳喂养的相关因素，并确定产后4个月初产妇中最具影响力的因素。
开展了一项横断面研究，研究对象为400名产后4个月的初产妇。
基于TPB在产后4个月收集母亲的母乳喂养知识、态度、主观规范和行为控制方面的数据。使用逻辑回归和人工神经网络分析这四个因素与纯母乳喂养结果之间的关联。
获得了272名母亲的回复。4个月时的纯母乳喂养率为34.4%。约66%和79%的母亲在产后的前两个月分别部分或完全停止了母乳喂养。结果显示，母乳喂养知识得分较高（OR = 1.09，95%CI = 1.04 - 1.14）、态度得分较高（OR = 1.04，95%CI = 1.00 - 1.09）、主观规范得分较高（OR = 1.22，95%CI = 1.11 - 1.34）以及行为控制得分较高（OR = 1.11，95%CI = 1.02 - 1.20）与更高的纯母乳喂养率相关。在这四个因素中，母乳喂养知识是促成纯母乳喂养的最重要因素。
基于TPB，母乳喂养知识、态度、主观规范和行为控制与纯母乳喂养呈正相关。未来的母乳喂养促进干预应针对这四个因素，尤其是母乳喂养知识，并持续至少产后两个月。
