Systematic reviews on prevalence estimates of child sexual abuse (CSA) worldwide included studies with adult participants referring on a period of abuse of about 50 years. Therefore we aimed to describe the current prevalence of CSA, taking into account geographical region, type of abuse, level of country development and research methods.
We included studies published between 2002 and 2009 that reported CSA in children below 18 years. We performed a random effects meta-analysis and analyzed moderator variables by meta-regression.
Fifty-five studies from 24 countries were included. According to four predefined types of sexual abuse, prevalence estimates ranged from 8 to 31 % for girls and 3 to 17 % for boys. Nine girls and 3 boys out of 100 are victims of forced intercourse. Heterogeneity between primary studies was high in all analyses.
Our results based on most recent data confirm results from previous reviews with adults. Surveys in children offer most recent estimates of CSA. Reducing heterogeneity between studies might be possible by standardized measures to make data more meaningful in international comparisons.
系统评价全球范围内儿童性虐待（CSA）的流行率估计值，纳入的研究对象为成年人，其报告的虐待期约为 50 年。因此，我们旨在描述 CSA 的当前流行率，同时考虑地理区域、虐待类型、国家发展水平和研究方法等因素。
我们纳入了 2002 年至 2009 年间发表的研究报告，这些研究报告涉及 18 岁以下儿童的 CSA 情况。我们进行了随机效应荟萃分析，并通过荟萃回归分析了调节变量。
来自 24 个国家的 55 项研究被纳入分析。根据四种预先定义的性虐待类型，女孩的流行率估计值为 8%至 31%，男孩的流行率估计值为 3%至 17%。每 100 名女孩中就有 9 名，每 100 名男孩中就有 3 名是被迫发生性行为的受害者。所有分析中，主要研究之间的异质性均较高。
我们基于最新数据得出的结果证实了之前针对成年人的综述结果。儿童调查提供了 CSA 的最新估计值。通过标准化措施来减少研究之间的异质性，可能会使数据在国际比较中更有意义。
