中国小学生数学困难(MD)的患病率及其相关因素尚不清楚。为制定适当的筛查和干预策略提供适当的基础,本研究旨在评估中国小学生中MD的患病率及其可能因素。从七个数据库中确定了文章,并包括了他们是否报告了中国小学生中MD的患病率。共检索到30881篇,其中975个进行了全面评估。总的来说,包括54项研究,涉及34,815名参与者(平均年龄9.86±3.13岁)。在统计软件环境R中使用Meta和Metafor软件包进行分析。我们使用meta回归和变量类型的亚组分析来评估潜在的患病率因素。中国小学生中MD的合并患病率为8.97%,而MD的患病率较低,中间,高年级小学占11.57%,10.07%,4.76%,分别。结果表明,中国小学儿童的MD患病率与年级水平和筛查MD所选择的临界点显着相关,初中小学的MD患病率女孩高于男孩。中国小学的MD患病率略高于英国和美国等国家。小学中低年级的MD患病率较高。在MD筛查过程中选择的等级和截止点与MD的患病率密切相关。应更多关注初中女孩的MD。

The prevalence of mathematical difficulties (MD) among primary school children in
China and its related factors remain unclear. To provide a suitable foundation for formulating appropriate screening and intervention strategies, this study aimed to estimate the prevalence of MD and its possible factors among primary school children in
China. Articles were identified from seven databases and included if they reported on the prevalence of MD among primary school children in
China. A total of 30,881 articles were retrieved, 975 of which were subjected to full evaluation. In total, 54 studies involving 34,815 participants (mean age 9.86 ± 3.13 years) were included. Analyses were conducted using the Meta and Metafor packages in the statistical software environment R. We used meta-regression and subgroup analyses by variable type to evaluate the potential prevalence factors. The pooled prevalence of MD among primary school children in
China was 8.97%, whereas the prevalence rates of MD in lower, middle, and upper primary schools were 11.57%, 10.07%, and 4.76%, respectively. The results showed that the prevalence of MD among primary school children in
China was significantly related to grade level and the cut-off points selected for screening MD and that the prevalence of MD in middle primary school was higher in girls than in boys. The prevalence of MD in primary schools in China was slightly higher than that in countries such as the United Kingdom and the United States. The prevalence of MD was higher in the lower and middle grades of primary school. The grade level and cut-off points selected during MD screening were closely related to the prevalence of MD. More attention should be paid to girls with MD in middle primary school.
