The objective of this research was to use a meta-analysis to understand the prevalence of hepatitis B or C in waste pickers worldwide.
Epidemiological studies on hepatitis B and C in waste pickers were included adopting a systematic review with meta-analysis. Each selected article had its quality scored by all authors, evaluated according to the Loney's criteria, and evaluated for quality and bias verified with a funnel plot.
After employing Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines, there were 12 studies used for this meta-analysis. The rate of hepatitis B seropositivity was 0.15 (95% CI 0.10-0.20), and hepatitis C was 0.08 (95% CI 0.04-0.12). This information suggests that waste pickers are exposed to many risks associated with poor quality of life working conditions as well as low health literacy rates.
The results of this meta-analysis confirm the vulnerability of waste pickers to hepatitis B and C infection and reinforce the importance of using personal protective equipment and immunizing workers.
本研究旨在通过荟萃分析了解全球拾荒者中乙型肝炎或丙型肝炎的流行情况。
采用系统评价和荟萃分析纳入了关于乙型肝炎和丙型肝炎在拾荒者中的流行病学研究。所有作者对每个入选的文章进行了质量评分，根据 Loney 标准进行评估，并通过漏斗图评估质量和偏倚。
采用系统评价和荟萃分析的 Preferred Reporting Items 指南后，有 12 项研究用于荟萃分析。乙型肝炎血清阳性率为 0.15（95%CI 0.10-0.20），丙型肝炎为 0.08（95%CI 0.04-0.12）。这表明，拾荒者面临着许多与生活条件质量差和健康素养低相关的风险。
这项荟萃分析的结果证实了拾荒者易感染乙型肝炎和丙型肝炎，这强调了使用个人防护设备和为工人接种疫苗的重要性。
