“…As for many developing countries, there are very few data on BMR in Brazilian samples. Absolute BMR values for men and women of Niterói were similar to the values of seventy male garbage collectors of mean age ,37 years (5888?2 (SE 106?2) kJ/d) (30) and eighty-one collegeaged women (4819?1 (SE 74?3) kJ/d) living in Rio de Janeiro, but lower than the values of forty-eight students of college age (twenty-three women) from southern Brazil (31) . Rodrigues et al (32) retrospectively analysed resting energy expenditure data of 760 Brazilian female participants in a hospital setting and the results were higher than the values found for women from Niterói.…”

Objective: To measure BMR in a probability sample of adults from an urban city of Brazil and to compare indirectly measured BMR (BMR i ) with BMR predicted from different equations. Design: BMR data were obtained by indirect calorimetry and estimated by different predictive equations (Schofield; Harris and Benedict; Henry and Rees). Anthropometric and body composition measures were also obtained. Setting: The Nutrition, Physical Activity and Health Survey (PNAFS), a household survey conducted in Niterói, Rio de Janeiro state, Brazil. Subjects: Representative sample of 529 adults (aged $20 years; 339 females) living in Niterói, Rio de Janeiro state, Brazil. Results: Mean BMR i values were 5839?7 (SE 73?9) kJ/d and 4758?1 (SE 39?5) kJ/d for men and women, respectively. Predicted BMR by all equations was significantly higher (difference between means and 95 % CI did not include zero) than BMR i in both men and women of all ages. Overall bias in BMR (predicted BMR minus BMR i ) using the Schofield equations (overestimation of about 20 %) was higher than when using the Henry and Rees equations (13 % and 16 % overestimation for males and females, respectively). The percentage of individuals whose BMR predicted by the Schofield equations fell within 10 % of BMR i was very low (7?8 % and 14?1 % of males and females, respectively). Conclusions: Current available predictive equations of BMR are not adequate to estimate BMR in Brazilians living in Niterói, Rio de Janeiro, Brazil.

“…The value from the mean heart rate per day for 314 GC worker-days measured in the winter of 1996 in Brazil (from June to November) was 97.6 ± 10.6, and the value from an mean heart rate for 308 GC worker-days at P act (mean time: 293 min) was 104.0 ± 11.7 10) . The value computed from the mean heart rate per day of 3 LOADER and 3 SOLO workers over 3 days in this study was 97.5 ± 11.8, approximately the same value as the results in the above 2 studies.…”

“…From heart rate measurement results of the GC, Kemper et al 7) and Luttmann et al 8) clarified that breaks of sufficient time and frequency are necessary, allowing GC to recover until their heart rate is not considered problematic. Anjos et al 9,10) also revealed the actual conditions of the workload by measuring the heart rate of GC, and appealed to set a limit on working hours in order to protect the health of workers in developing countries. In Japan, the Ministry of Labour issued a notice for disaster prevention to cleaning businesses in 1993 11) .…”

A Field Study on the Physiological Workload of Garbage Collectors in the Japanese Summer

2012

A field study designed to reveal the physiological workload on garbage collectors (GC) was conducted in Japan. Three drivers who only operated a garbage truck, three loaders who actually collected as a team, three solo collectors, and one clerical worker, totaling 10 male workers participated in this study. The ambient temperature and the relative humidity, activity intensity, and heart rate were measured on the three days in July. The mean heart rate of the workers, excluding the clerical worker, was 97.5 bpm. There were cases in which the heart rate limit, as defined by ACGIH, was exceeded, including a case in which the loader sustainably exceeded this limit for over an hour. There were 10 worker-days in which the 58%HRmax level (corresponding to the permissible limit specified in the Netherlands) was exceeded based on the findings of the 18 worker-days for the loaders and solo collectors. There were many cases in which the energetic load of GC in the humid summertime in Japan exceeded the permissible limits as established in the U.S.A. and the Netherlands. The careful inspection of the actual work conditions and improvements in the work environment should be implemented for the occupational safety and health of GC.

“…A execução da tarefa de coleta de lixo pode ser feita de forma manual, semiautomatizada ou automatizada, variando de acordo com o desenvolvimento tecnoló-gico do local, características demográficas da região e nível educacional e cultural da população 2 . Contudo, esta atividade está entre as ocupações de maior risco para a saúde dos trabalhadores 3. Os coletores de lixo estão constantemente expostos a esforços físicos durante a realização de suas atividades laborais, os quais envolvem caminhadas, corridas, subidas e descidas de ladeiras e levantamento e transporte de pesos variados ao longo do dia 4,5 . Um estudo realizado por Anjos e colaboradores 6 , concluiu que o gasto energético de um coletor de lixo durante o trabalho variou entre 288,4 e 319,1 kcal por hora, podendo alcançar um gasto de até 2000 kcal por período de trabalho, caracterizando o trabalho como pesado, de acordo com a Organização Mundial de Saúde.…”

“…Apesar de alguns estudos determinarem a exigência física e ergonômica desses trabalhadores 5,6 , ainda são escassas as pesquisas que avaliam esse tema específico. Portanto, o objetivo do presente estudo foi determinar o nível de atividade física (AF) total e nos diferentes domínios (lazer, deslocamento, ocupacional e doméstico) dos coletores de lixo de duas cidades de porte médio do Rio Grande do Sul/Brasil.…”

Nível de atividade física de coletores de lixo de duas cidades de porte médio do sul do Brasil Physical activity level of garbage collectors from two medium-sized cities in southern BrazilRodrigo Kohn Cardoso Resumo O objetivo do estudo foi verificar os níveis de atividade física (AF) total e nos diferentes domí-nios de coletores de lixo. Este estudo caracterizou-se como observacional descritivo e do tipo censo. A população foi composta por todos os coletores de lixo das cidades de Pelotas e Rio Grande, Rio Grande do Sul. A coleta de dados foi realizada por meio de um questionário contendo questões relativas a variáveis sociodemográficas, econômica, nutricional e comportamentais. O nível de atividade física foi avaliado através do Questionário Internacional de Atividade Física, IPAQ -versão longa. Foi realizada a análise univariada de todas as variáveis coletadas, com cálculo das medidas de tendência central e dispersão para as variáveis contínuas e proporções para as variáveis categóricas. Foram entrevistados todos os 127 coletores de lixo, sendo que a média de AF total relatada pelos trabalhadores foi de 4292,0 minutos por semana (DP 1034,2). Quando verificada a AF ocupacional, o escore médio encontrado foi de 3853,0 minutos por semana (DP 583,4). Os demais domínios, deslocamento, lazer e doméstico, apresentaram médias de AF semanal respectivamente de, 257,9 (DP 237,5), 77,6 (DP 111,5) e 103,5 (DP 101,8) minutos. Concluiu-se que os coletores de lixo estavam expostos a uma carga de AF total e ocupacional extremamente elevadas, podendo haver prejuízo significativo para a saúde se não forem adotadas medidas adequadas de nutrição e recuperação física. Palavras-chaveEpidemiologia, Trabalhadores, Saúde ocupacional, Lixo. AbstractThe aim of the present study was to verify levels of total physical activity (PA) domains, commuting, leisure and domestic had, respectively, means of 257.9 (SD 237.5), 77.6 (SD 111.5) and 103.5 (SD 101.8)
