BACKGROUND
The number of children with prenatal polysubstance exposure is increasing. Supportive mother-child interaction is a protective factor, which can ameliorate adverse effects of prenatal polysubstance exposure on developmental outcomes.
AIM
To examine the role of maternal verbal scaffolding on cognitive and language development in children with prenatal polysubstance exposure.
STUDY DESIGN
Pregnant women were recruited, and we prospectively followed mother-child dyads to 20 months of age. This analysis included 66 dyads (33 healthy controls and 33 with prenatal polysubstance exposure). Multivariable linear regression modelling was used to examine the cross-sectional association between maternal scaffolding and Bayley Scales of Infant and Toddler Development (BSID-III) score, as well as an interaction between the study group and scaffolding score.
OUTCOME MEASURES
The BSID-III cognitive and language score was used. Videotaped mother-child play was coded to obtain a maternal verbal scaffolding score. Effect sizes were measured using average differences in scores between groups.
RESULTS
There was no evidence of an association between study group and maternal scaffolding scores. Children in the polysubstance exposure group had lower cognitive and language scores compared to controls, but this association was not statistically significant after controlling for maternal education. Maternal scaffolding was predictive of language scores, with scores increasing by 1.24 points on average (95% CI: 0.42, 2.06) for every 1-point increase in scaffolding score after adjustment for covariates. There was no evidence of a study group-by-scaffolding interaction with respect to the language or cognitive scores.
CONCLUSIONS
Maternal scaffolding during play was associated with language development in children with and without prenatal polysubstance exposure.
背景
产前多物质暴露的儿童数量正在增加。支持性母婴互动是一种保护因素，可以减轻产前多物质暴露对发育结果的不良影响。
目的
研究母亲言语支架对产前多物质暴露儿童认知和语言发展的作用。
研究设计
招募孕妇，并前瞻性地随访母婴对子至 20 个月龄。本分析包括 66 对母婴（33 名健康对照组和 33 名产前多物质暴露组）。多变量线性回归模型用于检查母亲支架与贝利婴幼儿发展量表（BSID-III）评分之间的横断面关联，以及研究组与支架评分之间的交互作用。
结果
使用 BSID-III 认知和语言评分。对母婴游戏的录像进行编码，以获得母亲言语支架评分。使用组间评分的平均差异来测量效应大小。
没有证据表明研究组与母亲支架评分之间存在关联。与对照组相比，多物质暴露组儿童的认知和语言评分较低，但在控制了母亲教育后，这种关联没有统计学意义。母亲的支架与语言评分相关，支架评分每增加 1 分，平均语言评分增加 1.24 分（95%CI：0.42，2.06），调整了协变量后。在语言或认知评分方面，没有证据表明研究组与支架之间存在交互作用。
结论
在游戏中，母亲的支架与产前多物质暴露儿童和非暴露儿童的语言发展有关。
