Although maternal substance use is a known risk factor for child maltreatment, evidence on the scale of substance use is needed to inform prevention responses. This systematic review synthesised prevalence estimates of maternal substance use during pregnancy and early life among children at risk of maltreatment. Ovid, Pubmed, CINAHL, PsychInfo and ProQuest databases were searched. We included observational studies that sampled children at risk of maltreatment in high-income countries and reported information on maternal substance use during pregnancy and/or the child's first year of life. We extracted study characteristics and data to calculate prevalence, assessed risk of bias and conducted a narrative synthesis; there were insufficient comparable populations or outcomes to quantitatively synthesise results.

面临虐待风险的儿童在产前和生命早期母亲使用药物的负担：系统评价

尽管母体物质使用是虐待儿童的一个已知风险因素，但需要有关物质使用规模的证据来为预防措施提供信息。这项系统评价综合了对有虐待风险的儿童在怀孕期间和生命早期使用药物的流行率估计。检索了 Ovid、Pubmed、CINAHL、PsychInfo 和 ProQuest 数据库。我们纳入了观察性研究，对高收入国家面临虐待风险的儿童进行了抽样调查，并报告了母亲在怀孕期间和/或孩子一岁期间使用药物的信息。我们提取研究特征和数据来计算患病率，评估偏倚风险并进行叙述综合；没有足够的可比较人群或结果来定量综合结果。
