Abstract

Objective

Low maternal education is a risk factor for early childhood development (ECD), while exclusive breastfeeding (EBF) is a protective factor. This study examined the association between maternal education and ECD outcomes such as cognitive, language, and motor domains and whether EBF modifies this association in Brazil.

Methods

This cross-sectional study analyzed data from a non-probabilistic sample of 12-month-old infants born during the COVID-19. Moderation analyses using the Mann-Whitney test examined the effect of EBF at 6 months (effect modifier) on the relationship between Bayley-III cognitive, language, and motor scores as well as Bayley Global Score (BGS) (outcomes) and maternal education (independent variable). The effect size (r) from the sensitivity analysis of the effect modifier was estimated.

Results

A total of 269 full-term infants were evaluated. Higher maternal education was associated with better cognitive, language, and BGS (p < 0.00). EBF was associated with higher cognitive (p < 0.01), language (p < 0.02), and BGS (p < 0.00). EBF modified the effect of low maternal education (<10 years; and 10–12 years) on cognitive score and BGS. Among mothers with >10 years of education, a large effect size of EBF was observed on the BGS (r = 0.51), and a medium effect size was noted in the cognitive domain (r = 0.38).

Conclusion

Higher maternal education is associated with better scores on Bayley-III domains, and EBF can modify the effect of lower maternal education on ECD in Brazil. This is the first study to identify EBF as a mechanism to protect ECD in adverse conditions such as low maternal education.
纯母乳喂养改变了母亲教育和儿童发展之间的关系:一项嵌套在队列中的横断面研究。
目的:母亲受教育程度低是儿童早期发育(ECD)的危险因素,而纯母乳喂养(EBF)是保护因素。本研究考察了母亲教育与ECD结果(如认知、语言和运动领域)之间的关系,以及EBF是否改变了巴西的这种关系。方法:本横断面研究分析了COVID-19期间出生的12个月大婴儿的非概率样本数据。使用Mann-Whitney检验的适度分析检验了6个月时EBF(效果调节剂)对Bayley- iii认知、语言和运动评分以及Bayley全局评分(BGS)(结果)和母亲教育(自变量)之间关系的影响。从效应调节剂的敏感性分析中估计效应量(r)。结果:共对269例足月儿进行了评估。较高的母亲教育程度与更好的认知、语言和BGS相关(p ),10年教育,EBF对BGS有较大的效应量(r = 0.51),认知领域有中等效应量(r = 0.38)。结论:较高的母亲教育程度与较高的Bayley-III域得分相关,EBF可以修正巴西较低的母亲教育程度对ECD的影响。这是首次确定EBF是在不利条件下(如产妇教育程度低)保护ECD的机制。
