Risk factors for musculoskeletal symptoms among crawfish farmers in Louisiana--a pilot study.
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.
