O trabalho terceirizado e por turnos está associado ao aumento do risco de COVID-19? Descobertas de um estudo com trabalhadores da mineração
Open accessAbstract
Resumo Objetivos: investigar os fatores de risco sociodemográficos e ocupacionais associados à infeção por COVID-19 em trabalhadores da mineração. Métodos: estudo de coorte retrospectivo com dados secundários dos trabalhadores de uma empresa multinacional de mineração, de março de 2020 a abril de 2021. Casos de COVID-19 foram definidos por meio do resultado do teste reação em cadeia da polimerase (PCR) positivo para SARS-CoV-2. Riscos relativos (RR) para testes positivos foram obtidos por regressão de Poisson. Resultados: dos 10.484 trabalhadores testados, 2.578 (24,6%) tiveram pelo menos um resultado positivo. Foi realizada uma média de 4,0 (desvio-padrão: 3,6) testes para cada trabalhador, totalizando 41.962 testes. A maioria dos trabalhadores eram do sexo masculino (88,3%), com idade entre 30 e 39 anos (38,7%), terceirizados (74,1%) e que não trabalhavam em turnos (70,5%). No modelo múltiplo, os trabalhadores terceirizados (RR: 1,39; intervalo de confiança de 95% [IC95%]: 1,27;1,51) e trabalhadores por turnos (RR: 1,10; IC95%: 1,01;1,20) apresentavam maior risco de infecção quando comparados com seus homólogos. Conclusões: os trabalhadores terceirizados e por turnos exibiram maior risco de infecção pelo SARS-CoV-2 quando comparados com seus homólogos. Portanto, é necessário fornecer monitoramento contínuo com oferta regular e adequada de testes para mitigação e prevenção da COVID-19 nestes grupos ocupacionais.

In the citing paper
“With informal work making up approximately 54% of all employment in the region – as well as more than 60% in countries like Colombia and Peru – many informal workers were impacted by the lack of employment protections and have had to continue to work in precarious conditions [24–28].”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
