OBJECTIVE
To describe the hepatitis B prevalence in Brazilian waste pickers.
METHODS
We performed a literature search in the SciELO, Biblioteca Virtual em Saúde (BVS), PubMed and Web of Science databases using the descriptors: "hepatitis B" AND ("informal recycling" OR "waste picker" OR "recyclable waste collectors" OR "solid waste segregator") AND ("recyclable waste" OR "solid waste") AND Brazil. Epidemiological studies on HBV in Brazilian waste pickers published prior to February 2020 were included and evaluated for quality and bias using a funnel plot.
RESULTS
This meta-analysis consisted of five articles. Prevalence of HBV surface antigen seropositivity was 14% (95%CI: 6%-22%) in Brazilian waste pickers.
CONCLUSION
HBV prevalence in Brazilian waste pickers remains high. There should be more campaigns showing the importance of vaccination and personal protective equipment use.
目的
描述巴西拾荒者中乙型肝炎的流行情况。
方法
我们在 SciELO、巴西虚拟健康图书馆（BVS）、PubMed 和 Web of Science 数据库中使用以下术语进行文献检索：“乙型肝炎”和（“非正式回收”或“拾荒者”或“可回收废物收集者”或“固体废物分类者”）和（“可回收废物”或“固体废物”）和巴西。纳入了 2020 年 2 月之前发表的关于巴西拾荒者中 HBV 的流行病学研究，并使用漏斗图评估其质量和偏倚。
结果
这项荟萃分析包括五篇文章。巴西拾荒者中 HBV 表面抗原血清阳性率为 14%（95%CI：6%-22%）。
结论
巴西拾荒者中 HBV 的流行率仍然很高。应该开展更多宣传活动，强调接种疫苗和使用个人防护设备的重要性。
