Musculoskeletal pain in Brazilian sugar cane cutters
该研究调查了巴西甘蔗收割工肌肉骨骼疼痛的普遍程度，发现下背痛最常见，但整体报告率较低，可能与就业不稳定有关。
<h3>Objectives</h3> The worker involved in the sugar cane cut is exposed to both physical and mental health risks, due to several body movements that demand intense physical effort, along with inappropriate posture and exposure to different climate conditions. These aspects have caused working accidents and sickness such as musculoskeletal problems. This study aimed to assess the prevalence of musculoskeletal symptoms in Brazilian sugar cane cutters, as part of the multi-national CUPID study. <h3>Methods</h3> A cross-sectional survey was carried out in a target population of 300 sugar cane cutters at an alcohol and sugar factory in São Paulo, Brazil, during the 2009 harvest. The data were collected at interview, using the Portuguese version of the standardised CUPID questionnaire. <h3>Results</h3> Interviews were completed with 182 (60.6%) subjects, most of whom (94.5%) were men. Their average age was 35 years, and 63,6% were younger than 41 years. 29.8% of the participating workers reported low back pain in the past year, 4.4% neck pain, 4.4% shoulder pain, 7.9% elbow pain, 2.3% wrist/hand pain, and 2.3% knee pain. <h3>Conclusions</h3> Work as a sugar cane cutter is physically demanding, and their relatively low frequency of reported pain is therefore remarkable. Their employment was more precarious that that of many other occupational groups, and this may have led them to under-report musculoskeletal pain.
