          Abstract

          Low back pain (LBP) is a major public health issue. There is lack of research on this disorder affecting urban cleaning workers. A cross-sectional study was conducted to describe the prevalence of LBP, occupational and extra-occupational characteristics, as well as associated factors in these workers. A census was performed with 624 workers in Salvador, Brazil, using a questionnaire administered by an interviewer in 2010. Cases of LBP were defined by reported symptoms of pain in the previous 12 months, lasting more than a week or with monthly minimum frequency, which led to restrictions at work or to seeking medical attention, or in cases when respondents had a severity score > 3 on a numerical scale from 0 to 5. Physical demands at work were measured on a numerical 6-point scale with 14 variables. Psychosocial demands were measured using the Job Content Questionnaire. Sociodemographic factors, lifestyle habits and domestic work were evaluated. Multiple logistic regression (LR) was used to identify factors associated with LBP, for which the prevalence was 37.0%. Among them, 62.8% of workers felt pain in the last 7 days. LBP was associated with longer working hours, flexion and trunk rotation, psychosocial demands, working directly in collection and low schooling. Dynamic work (walking, running) served as a protective factor. It was concluded that many workers develop their activity at the presence of pain. The results emphasize the need for preventive measures through multifactorial approach encompassing adaptations in physical environment and changes in work organization.

          Lombalgia é um dos maiores problemas de saúde pública. Existe uma lacuna nos estudos sobre este agravo em trabalhadores de limpeza urbana (TLU). Estudo de corte transversal foi realizado para descrever prevalência de lombalgia, características ocupacionais, extra-ocupacionais e fatores associados a este agravo em TLU. Foi feito censo com 624 trabalhadores, em Salvador, utilizando questionário aplicado por entrevistador, em 2010. Casos de lombalgia foram definidos como dor lombar referida nos últimos 12 meses, durando mais que 1 semana ou tendo frequência mínima mensal, que determinou restrição ao trabalho ou busca por atenção médica ou apresentou intensidade > 3 em escala de 0 a 5. Demandas físicas no trabalho foram medidas em escala numérica de 6 pontos para 14 variáveis. Demandas psicossociais foram medidas utilizando o Job Content Questionnaire. Fatores sociodemográficos, de hábitos de vida e trabalho doméstico foram avaliados. Regressão logística múltipla (RL) foi utilizada para identificar fatores associados à lombalgia, cuja prevalência foi de 37,0%, e entre os casos, 62,8% cursavam com dor nos últimos 7 dias. A lombalgia se associou ao maior tempo de trabalho, à flexão e rotação do tronco, às demandas psicossociais, ao trabalho direto na coleta e à baixa escolaridade. O trabalho dinâmico (andando, correndo) atuou como fator de proteção. Concluiu-se que muitos trabalhadores desenvolvem sua atividade na presença de dor. Os resultados apontam para necessidade de medidas de prevenção através de abordagem multifatorial que inclua adequações no ambiente físico e modificações na organização do trabalho.
