The prevalence of developmental coordination disorder in children: a systematic review and meta-analysis

Purpose: The aim of the study was to synthesize previous evidence and clarify the prevalence of developmental coordination disorder (DCD) in children by meta-analysis. Methods: A comprehensive computerized search of databases, including PubMed, Embase, Web of Science, The Cochrane Library, CINAHL, and PsycINFO databases, was conducted to identify relevant national and international articles published before 18 December 2023 on DCD prevalence in children. The meta-analysis of prevalence was conducted using Stata 18.0. Results: A total of 18 papers involving 31,203 patients were included. The prevalence of children with DCD was found to be 5%. A subgroup analysis showed that prevalence was 7% [95% confidence interval (CI) 4%-10%] and 4% (95% CI 3%-7%) for boys and girls, respectively; 4% (95% CI 2%-8%), 2% (95% CI 2%-2%), and 6% (95% CI 3%-10%) in Asia, Europe, and North America, respectively; and 18% (95% CI 8%-31%) and 6% (95% CI 4%-7%) for preterm (<37 weeks) and term infants (>= 37 weeks), respectively. The prevalence of very low birth weight children (<1,250 g) with DCD was found to be 31%. Conclusion: In this study, we found that the prevalence of children with DCD in the general population was 5% and that preterm infants (<37 weeks) and very low birth weight infants (<1,250 g) have a higher prevalence of DCD and require early screening and regular follow-up.
