Trabalho e desgaste de migrantes no corte manual de cana de açúcar no Estado de São Paulo, Brasil

The scope of this paper is to describe the work of manual sugarcane harvesters, assessing the nutritional behavior and body composition between the beginning and the end of the harvest. A descriptive longitudinal study was made of harvesters in Piracicaba, São Paulo, Brazil, who answered a socio-demographic questionnaire and authorized measurement of Body Mass Index, Body Fat Percentage and Arm Muscle Circumference at three stages. Creatine kinase on the skeletal isoform, C-reactive protein and plasma urea were measured at the end of the harvest. Thirty male migrant harvesters with ages ranging from 18 to 44 from the Northeast (Ceará) were assessed over a nine-month period. The workers suffered significant body fat and weight loss in the first half of the harvest. Eighteen workers had abnormal levels of creatine kinase and four - out of 24 who had donated blood - had altered urea levels. Sugarcane harvesting work causes weight and body fat loss and gains in the lean body mass index, which suffers wear-out when working on consecutive harvests. It can also cause changes in biochemical markers of chronic systemic inflammation. Further studies will make it possible to comprehend the relationships between stress, wear-out, labor longevity and health in sugarcane harvesting.Descrever o trabalho de cortadores manuais de cana de açúcar avaliando o comportamento nutricional e a composição corporal do início ao final da safra. Estudo descritivo longitudinal de cortadores na região de Piracicaba, São Paulo, Brasil, por meio de um questionário sociodemográfico e antropométrico que permitiu medir Índice de Massa Corporal, Percentual de Gordura Corporal e Circunferência Muscular do Braço em três momentos. Ao final da safra foi dosada a Creatina Quinase na isoforma esquelética, proteína C reativa e ureia plasmática. Durante nove meses, 30 homens safristas migrantes nordestinos (Ceará), com idade de 18 a 44 anos foram estudados. Os trabalhadores tiveram perda significativa de gordura corporal e peso na primeira metade da safra. A maioria ganhou massa magra e os mais velhos na atividade ganharam menos. Dezoito trabalhadores apresentaram valores alterados de Creatina Quinase e quatro tiveram uréia alterada dentre os 24 que cederam sangue. O trabalho no corte de cana gera perda de peso e gordura corporal e aumento de massa magra que se desgasta com a história de trabalho em safras sucessivas. Pode ainda causar alteração de marcadores bioquímicos de inflamação crônica sistêmica. Novos estudos permitirão entender a relação esforço, desgaste, longevidade laboral e saúde no corte de cana.2831284
