The prevalence of musculoskeletal symptoms (MSS) among crawfish farmers is unknown. The purpose of this study was to assess the prevalence of MSS in nine body regions among crawfish farmers, and to examine associations between MSS and crawfish farm work activities. Questionnaires were mailed to randomly selected crawfish farmers in the State of Louisiana, USA. Site-specific MSS, demographics, and crawfish farm work information was obtained from the previous six months. Odds ratios (ORs) and 95% confidence intervals (CIs) were estimated with logistic regression adjusting for potential confounders. Among the participants (N = 184), shoulder MSS were reported most frequently (62%). Wrist/hand and low back MSS were significantly associated with tractor use (OR(adj) = 2.89; 95% CI = 1.28-6.56) and (OR(adj) = 2.41; 95% CI = 1.03-5.67), respectively. Also, upper back MSS were associated with the number of years working on a crawfish farm (OR(adj) = 3.07; 95% CI = 1.17-8.04). Shoulder and low back MSS were common. Tractor use may increase the risk of wrist/hand and low back MSS. Future studies need accurately assess exposures to physical risk factors for MSS so ergonomic interventions can be developed.
小龙虾养殖户肌肉骨骼症状（MSS）的流行情况尚不清楚。本研究旨在评估 9 个身体部位 MSS 在小龙虾养殖户中的流行程度，并探讨 MSS 与小龙虾养殖工作活动之间的关系。研究人员向美国路易斯安那州随机选择的小龙虾养殖户邮寄了问卷。从过去 6 个月中获得了特定部位 MSS、人口统计学和小龙虾养殖工作信息。采用 logistic 回归调整潜在混杂因素后，估计了比值比（OR）和 95%置信区间（CI）。在参与者中（N=184），肩部 MSS 报告最频繁（62%）。手腕/手部和腰部 MSS 与拖拉机使用显著相关（OR（adj）=2.89；95%CI=1.28-6.56）和（OR（adj）=2.41；95%CI=1.03-5.67）。此外，上背部 MSS 与在小龙虾养殖场工作的年数有关（OR（adj）=3.07；95%CI=1.17-8.04）。肩部和腰部 MSS 很常见。拖拉机的使用可能会增加手腕/手部和腰部 MSS 的风险。未来的研究需要准确评估 MSS 的物理风险因素暴露情况，以便制定工效学干预措施。
