In Reply We thank Sun et al for the letter concerning our study¹ in which we described the trends in prevalence of measured overweight and obesity among children aged 2 to 13 years in 28 European countries from 1999 to 2016 using a systematic methodology. Sun et al have questioned the use of Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) requirements² because the detailed recovery strategy does not appear in the article. The study¹ was conducted according to the Meta-analysis of Observational Studies in Epidemiology (MOOSE) reporting guideline³ and the PRISMA reporting guideline.² Additionally, we have registered this review on PROSPERO, and its protocol has been published elsewhere.⁴ We disagree with the point because the search strategy is described in detail in eTable 1 in the Supplement.

在答复中，我们感谢Sun等人关于我们研究¹的来信，其中我们使用系统的方法描述了1999年至2016年间28个欧洲国家2至13岁儿童中测得的超重和肥胖患病率的趋势。Sun等人质疑将首选报告项目用于系统评价和元分析（PRISMA）要求^2，因为详细的恢复策略未出现在本文中。研究¹是根据流行病学观察性研究（MOOSE）报告指南³和PRISMA报告指南的荟萃分析进行的。²此外，我们已在PROSPERO上注册了此评论，其协议已在其他地方发布。⁴我们不同意这一点，因为补编中的eTable 1中详细描述了搜索策略。
