Abstract

Objective

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.

Methods

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.

Results

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.

Conclusions

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.

母乳喂养时间与 2-3 岁中国儿童神经发育的关系

目的本研究旨在探讨中国人群中2至3岁儿童母乳喂养时间与神经发育之间的关系。方法本研究基于横断面调查。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。通过访谈式问卷了解了父母和儿童的特征以及母乳喂养持续时间。儿童的神经心理发育情况由经过培训的儿童保健医生使用儿童心理发育量表进行评估。采用多变量线性回归模型分析了母乳喂养持续时间与神经心理发育之间的关系。在多变量线性回归模型中，在调整了潜在的混杂因素后，母乳喂养 7-12 个月的儿童的粗大运动发育提高了 3.59 分（β = 3.59；95 % 置信区间 [CI]：1.与从未接受母乳喂养的儿童相比，接受 7-12 个月母乳喂养的儿童的大运动发育提高了 3.59 个百分点（β = 3.59；95 % 置信区间 [CI]：1.23 至 6.34），精细运动发育提高了 3.73 个百分点（β = 3.73；95 % 置信区间 [CI]：1.09 至 6.47），语言发育提高了 2.87 个百分点（β = 2.87；95 % 置信区间 [CI]：1.12 至 5.31）。与从未进行母乳喂养的儿童相比，母乳喂养 12 个月的儿童精细动作发育提高了 3.77 分（β = 3.77；95 % CI：0.98 至 6.86）。应鼓励中国的母亲开始并继续母乳喂养。

期刊介绍： Infant Behavior & Development publishes empirical (fundamental and clinical), theoretical, methodological and review papers. Brief reports dealing with behavioral development during infancy (up to 3 years) will also be considered. Papers of an inter- and multidisciplinary nature, for example neuroscience, non-linear dynamics and modelling approaches, are particularly encouraged. Areas covered by the journal include cognitive development, emotional development, perception, perception-action coupling, motor development and socialisation.
