Musculoskeletal symptoms and work ability among agricultural machinery operators

Those subjects whose employment has physical demands present more frequently musculoskeletal symptoms than others. The agricultural sector activities include tasks with important physical demands that may have a negative impact in the workers health. The aim of this study was to evaluate the presence of musculoskeletal symptoms and its association with work ability in agricultural machinery operators. It is a cross-sectional study. The participants (n=204) answered a self-administered questionnaire on demographics, work and lifestyle characteristics, Work Ability Index and the Nordic Musculoskeletal Symptoms Questionnaire. The response rate was 89.78%. The mean age of the workers was 32.3 years, and 47.1% of them reported musculoskeletal symptoms at least one body part over the past 12 months. Those subjects who presented work ability index <37 points, 87.5% reported some kind of musculoskeletal symptom. This study showed that the work ability was significantly (p <= 0.05) correlated to musculoskeletal symptoms presence. It is recommended that measures to promote and improve the work ability are designed and deployed based on musculoskeletal disorders prevention.
