Abstract:O artigo aborda epidemiologicamente o perfil dos coletores de lixo seletivo e descreve as lesões musculares e acidentes de trabalho mais freqüentes. Este estudo transversal foi desenvolvido com duas empresas (denominadas como empresa A e empresa B), em Porto Alegre, selecionando-se 50 funcionários aleatoriamente (presentes e aptos nos dias das entrevistas para a pesquisa) e aos quais foi aplicado um questionário. A Média de idade da amostra foi de 34 e 22 anos para a empresa A e B, respectivamente. Cerca de 66… Show more
“…The mean age found among the UCWs in this study was compatible with the mean of other studies in the same category 17,21 , thus showing the relatively Young profile of this category, which can reflect on physical demands of the developed tasks, leading to overload for the body.…”

“…The possible consequence for that is the submission to difficult conditions in this activities and the low interlocution with the management for better work conditions. The intake of alcohol among these workers is very high 21,23,24 . This study demonstrated high frequency of alcohol intake at least once a week, and this result is compatible with other studies in the same category, which indicate the stressful activity of public waste collection as the precursor of the onset of alcohol intake, calling the attention to the risk of alcoholism among waste collectors 23,24 .…”

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.

“…No que se refere, ainda, à afirmação anterior, Santos [17], descreve os riscos que o coletor de resíduos está sujeito durante o trabalho são de ordem mecânica (cortes, perfurações, atropelamentos, quedas), ergonômica (esforço excessivo), biológica (agentes biológicos), química (substâncias químicas tóxicas) e social (falta de treinamento para a atividade). Existem também os riscos de acidentes ocasionados por diversos fatores como: acondicionamento inadequado do lixo, mão de obra desqualificada, excesso de peso a que são submetidos e uso inadequado dos equipamentos de proteção individual [10].…”
Este artigo analisa o trabalho do profissional responsável pela coleta de resíduo sólido acondicionado e descartado pela população residencial das cidades. Essa atividade é realizada por meio de um esforço físico considerável do indivíduo. Além do esforço físico, existem situações de intempéries, mau acondicionamento dos produtos no lixo causando diversos cortes e perfurações nos trabalhadores. Este trabalho procura demonstrar as abordagens e ferramentas da Ergonomia na investigação da atividade laboral do coletor de lixo. Para isso, parte-se de uma breve revisão bibliográfica discutindo a importância desta atividade e os seus riscos diários: físicos, biológicos e ambientais. Também a partir da aplicação de ferramentas ergonômicas investigativas constataram-se aspectos relevantes a essa situação de trabalho. O resultado da pesquisa apresenta recomendações que identificam que os atuais equipamentos de proteção individual, devem ter um desenvolvimento projetual mais assertivos quando investigada a atividade e o usuário no contexto de uso, levando em consideração a opinião do usuário e a percepção do projetista em relação ao produto investigado.
To describe the work ability and health problems among Brazilian recyclable waste pickers. Sixty-one workers answered questionnaires related to the work ability (Work Ability Index-WAI), musculoskeletal problems (Nordic Musculoskeletal Questionnaire-NMQ), low back related disability (Roland Morris Questionnaire-RMQ), physical activity (International Physical Activity Questionnaire-IPAQ), smoking (Fagerström Test for Nicotine Dependence-FTND), and alcohol use (The Alcohol Use Disorders Identification Test AUDIT). Brazilian recyclable waste pickers are mostly young (25-44 years old: 54%), women (88%) with low schooling (incomplete elementary school: 54%), high turnover at work (job seniority < 12 months: 70%), low rates of sick leave (20%) and accidents at work (13%). The workers reported good (44%) or optimal (43%) work ability. The prevalence of musculoskeletal disorders in the last 12 months was high (lower back: 49%, shoulders: 28%, neck: 23%, wrists and hands: 21%), as well as the prevalence of hypertension (28%). Most of the workers reported to be physically active or very active (57%), smoke (34%) and drink alcohol (44%). This study outlined the profile of recyclable waste pickers regarding work ability and health problems, which highlight the need for preventive measures focused on musculoskeletal and cardiovascular diseases among this population.
