The aim of this study was to explore the relationship between breastfeeding duration and neurodevelopment in children aged 2 to 3 years in a Chinese population.
This study was based on a cross-sectional survey. The data were from the National Nutrition and Health Systematic Survey for children in China which was conducted from 2019 to 2020. Characteristics of parents and children and the breastfeeding duration were obtained using interview-administered questionnaires. Children's neuropsychological development was assessed by a trained child health care physician using the Child Psychological Development Scale. A multivariable linear regression model was used to analyze the association between breastfeeding duration and neuropsychological development.
A total 1290 children aged 2-3 years were included in the present analysis. In multivariable linear regression models, after adjustment for potential confounders, children who were breastfed for 7-12 months had a 3.59-point increase in gross motor development (β = 3.59; 95 % confidence interval [CI]: 1.23 to 6.34), a 3.73-point increase in fine motor development (β = 3.73; 95 % CI: 1.09 to 6.47), and a 2.87-point in language development (β = 2.87; 95 % CI: 1.12 to 5.31) compared with those who were never breastfed. Children who were breastfed for > 12 months had a 3.77-point increase in fine motor development (β = 3.77; 95 % CI: 0.98 to 6.86) compared with those who were never breastfed.
Longer breastfeeding duration was associated with increased gross motor, fine motor, and language scores in our study population. Mothers in China should be encouraged to initiate and continue breastfeeding.
本研究旨在探讨中国人群中2至3岁儿童的母乳喂养时长与神经发育之间的关系。
本研究基于一项横断面调查。数据来自2019年至2020年开展的中国儿童营养与健康系统调查。通过访谈问卷获取家长和儿童的特征以及母乳喂养时长。由经过培训的儿童保健医生使用儿童心理发展量表评估儿童的神经心理发育情况。采用多变量线性回归模型分析母乳喂养时长与神经心理发育之间的关联。
本分析共纳入1290名2至3岁儿童。在多变量线性回归模型中，在对潜在混杂因素进行调整后，与从未母乳喂养的儿童相比，母乳喂养7至12个月的儿童在大运动发育方面得分增加3.59分（β = 3.59；95%置信区间[CI]：1.23至6.34），精细运动发育方面得分增加3.73分（β = 3.73；95% CI：1.09至6.47），语言发育方面得分增加2.87分（β = 2.87；95% CI：1.12至5.31）。与从未母乳喂养的儿童相比，母乳喂养超过12个月的儿童在精细运动发育方面得分增加3.77分（β = 3.77；95% CI：0.98至6.86）。
在我们的研究人群中，较长的母乳喂养时长与大运动、精细运动和语言得分增加相关。应鼓励中国母亲开始并持续进行母乳喂养。
