Despite tobacco farming involving intensive manual labor, chronic low back pain (CLBP) prevalence and associated factors are unknown among this occupational group.
This was a cross-sectional study conducted in southern Brazil. A random sample of tobacco farmers was interviewed. Socioeconomic and individual characteristics, occupational tasks, workloads, and comorbidities were investigated. Chronic low back pain prevalence was described in relation to independent variables, and associations were examined with Poisson regression.
Chronic low back pain prevalence was 8·4%. Increasing age, rearing two or more species of livestock (PR 1·65), exposure to tasks that require heavy physical exertion (PR 2·00), working in awkward postures (PR 1·36), green tobacco sickness (GTS) (PR 1·63), pesticide poisoning (PR 2·37), and minor psychiatric disorders (PR 2·55) were associated with CLBP.
This study found that CLBP is a relevant health problem among tobacco farmers and highlights understudied risk factors such as pesticide poisoning and GTS. Policies to minimize exposure to physiological and chemical workloads in tobacco planting to prevent CLBP are needed. Health professionals should be trained to diagnose and prevent acute low back pain episodes and thus prevent/minimize limitations and disabilities due to CLBP.
尽管烟草种植涉及高强度体力劳动，但该职业群体中慢性腰痛（CLBP）的患病率及相关因素尚不清楚。
这是一项在巴西南部进行的横断面研究。对烟草种植户进行随机抽样访谈。调查社会经济和个人特征、职业任务、工作量及合并症。根据自变量描述慢性腰痛患病率，并通过泊松回归分析关联。
慢性腰痛患病率为8.4%。年龄增长、饲养两种或更多种类牲畜（患病率比1.65）、从事需要重度体力消耗的任务（患病率比2.00）、以别扭姿势工作（患病率比1.36）、绿烟草病（GTS）（患病率比1.63）、农药中毒（患病率比2.37）以及轻度精神障碍（患病率比2.55）与慢性腰痛相关。
本研究发现慢性腰痛是烟草种植户中的一个重要健康问题，并突出了农药中毒和绿烟草病等研究不足的风险因素。需要制定政策以尽量减少烟草种植中生理和化学工作量的暴露，预防慢性腰痛。应培训卫生专业人员诊断和预防急性腰痛发作，从而预防/尽量减少因慢性腰痛导致的限制和残疾。
