Work-related musculoskeletal disorders among occupational fishermen: a systematic literature review

Abstract

BackgroundCommercial fishing constitutes an increased risk of musculoskeletal disorders (MSD), as it consists of heavy workloads and uncontrollable strenuous settings. The aims of this systematic review were to describe the prevalence of MSD among occupational fishermen and to identify risk factors for onset work-related MSD.MethodsAll studies investigating MSD in occupational fishermen were systematically identified and reviewed. Searched databases were PubMed/MEDLINE, EMBASE and CINAHL. Two independent researchers performed the quality assessments of the studies.ResultsFrom 292 articles identified, 16 articles consisting of 13 studies were suitable for inclusion. Prevalence of overall MSD ranged from 15% to 93%. The only consistent work-related risk factor was ‘working part time’, while other risk factors, such as vessel and job type showed conflicting results.ConclusionMSDs in occupational fishermen are common across countries. Variations observed in MSD prevalence might be due to differences in methodology, populations and definitions of MSD. Evidence on work-related risk factors for MSD is sparse and most studies were of poor methodological quality. Only working part time was identified as a consistent risk factor for MSD possibly caused by a healthy worker effect. There is a need for investigating causality in longitudinal studies, including both active and retired fishermen to better understand the complexity of MSD.PROSPERO registration numberCRD42020147318
