INTRODUCTION
Obesity and overweight are an emerging problem in Africa. Obese children are at increased risk of developing hypertension, high cholesterol, orthopaedic problems and type 2 diabetes as well as increased risk of adult obesity. Prevention of childhood overweight and obesity therefore needs high priority. The review approach is particularly useful in establishing whether research findings are consistent and can be generalised across populations and settings. This systematic review aims to assess the magnitude and distribution of overweight and obesity among primary school learners within populations in Africa.
METHODS AND ANALYSIS
A comprehensive search of key bibliographic databases including MEDLINE (PubMed), MEDLINE (EbscoHost), CINAHL (EbscoHost), Academic Search Complete (EbscoHost) and ISI Web of Science (Science Citation Index) will be conducted for published literature. Grey literature will be also be obtained. Full-text articles of eligible studies will be obtained and screened following predefined inclusion criteria. The quality of reporting as well as risk of bias of included studies will be assessed, data extracted and synthesised. The results will be summarised and presented by country and major regional groupings. Meta-analysis will be conducted for identical variables across studies. This review will be reported following the MOOSE Guidelines for Meta-Analysis and Systematic Reviews of Observational Studies.
ETHICS AND DISSEMINATION
Ethics is not a requirement since no primary data will be collected. All data that will be presented in this review are based on published articles. The findings of this systematic review will be submitted for publication in peer-reviewed journals and disseminated in national and international conferences and also in policy documents to appropriate bodies for decision-making, where needed. It is expected that the findings will identify some research gaps for further studies.
简介
肥胖和超重是非洲日益严重的问题。肥胖儿童患高血压、高胆固醇、骨科问题和 2 型糖尿病的风险增加，成年肥胖的风险也增加。因此，预防儿童超重和肥胖需要高度重视。综述方法特别有助于确定研究结果是否一致，是否可以在人群和环境中推广。本系统综述旨在评估非洲人群中小学生超重和肥胖的程度和分布。
方法和分析
将对包括 MEDLINE（PubMed）、MEDLINE（EbscoHost）、CINAHL（EbscoHost）、Academic Search Complete（EbscoHost）和 ISI Web of Science（科学引文索引）在内的主要文献数据库进行全面搜索，以获取已发表的文献。还将获取灰色文献。将获得符合条件的研究的全文文章，并按照预先确定的纳入标准进行筛选。将评估报告的质量和纳入研究的偏倚风险，提取和综合数据。结果将按国家和主要区域分组进行总结和呈现。将对研究之间相同的变量进行荟萃分析。本综述将按照 MOOSE 指南进行报告，该指南用于对观察性研究进行荟萃分析和系统综述。
伦理和传播
由于不会收集原始数据，因此不需要伦理。本综述中呈现的所有数据均基于已发表的文章。本系统综述的结果将提交给同行评议期刊发表，并在国家和国际会议上以及在适当的决策机构的政策文件中传播，在需要的情况下。预计这些发现将确定一些进一步研究的研究空白。
