Padrão de mortalidade por câncer em trabalhadores eletricitários

Abstract

This study provides the cancer mortality pattern for a cohort of 10,017 electric power plant workers from 1978 to 1994. Standard mortality ratio (SMR) analysis showed lower mortality from all causes (0.47: 0.43-0.51) and from all groups of causes including neoplasms (0.73: 0.60-0.90) among these workers, in comparison with the same sex and age bracket in Rio de Janeiro. In relation to specific cancer sites, standard cancer mortality ratios (SCMRs) greater than one were observed for neoplasms of the small bowel (10.35: 3.34-32.09), gallbladder (2.64: 0.99-7.03), pancreas (1.83: 0.91-3.66), kidney (2.91: 1.39-6.10), and bladder (2.60: 0.58-4.12), as well as for melanoma (1.82: 0.46-7.28). Important limitations were the workers' relatively young age and the short period of time since job admission (less than 15 years). The small number of deaths for each anatomic site led to instability in the study results, with many non-significant SCMRs and wide confidence intervals. Due to these limitations, study results are difficult to interpret in light of currently available evidence.

Fatores associados à capacidade para o trabalho de trabalhadores do Setor Elétrico

“…A população de estudo apresentou perfil só-cio-demográfico, dos estilos de vida e do estado de saúde com melhores resultados do que a população geral de São Paulo, sendo que uma discussão detalhada sobre estes resultados está apresentada em outra publicação 18 . Cabe ressaltar que a população de estudo teve melhor padrão do que a população geral no que diz respeito à remuneração e ao nível de escolaridade, e que este padrão diferenciado também foi identificado em um estudo junto aos eletricitários do Rio de Janeiro 26 . A comparação com outros estudos 27,28,29,30 também mostrou perfil mais favorável da população de estudo quanto ao tabagismo e à prática de atividades físicas.…”

Feasibility study for a long-term follow-up in a historical cohort of Brazilian coal miners

“…Also using multiple search methods, the authors reported a follow-up success rate of 93%, and the cause of death could be identified in 99% of the cases. Mattos et al (2002) conducted a cohort study of 10 017 electric power plant workers from 1978 to 1994. Follow-up information and cause of death identification was obtained directly from the electric power industry through the company payroll and Social Security.…”

Perception of risk from electric and magnetic fields: Stress effects and psychological aspects

“…In this respect, studies (Beecher et al, 2005) have attempted to verify whether increasing the technical information provided to lay people would affect risk perception. Although this issue has been dealt with by the various governments who have tried to promote better risk communication and enhanced public participation in decisions on the siting of electrical installations (Mattos, Sauaia & Menezes, 2002), it remains a sensitive question (Wiedemann & Schütz, 2005). Some authors feel that public risk perception must be recognized as a factor in the decision to apply precautionary measures and that the public should always be informed.…”
