Occupational Ergonomic Factors and Musculoskeletal Symptoms in Healthcare Personnel: A Study in Barranquilla (Colombia)

Abstract

The correlation between work exposure time, physical job demands, subjective perception of exertion, and the presence of musculoskeletal discomfort was analyzed as a strategy to generate evidence supporting preventive ergonomic interventions. A quantitative study was conducted, employing a descriptive, explanatory, and correlational research design. Data collection was carried out using a questionnaire on ergonomic risk factors and potential health effects, developed by the Trade Union Institute for Work, Environment and Health. The study sample consisted of 108 healthcare workers from the Keralty Group, engaged in the provision of medical services. A high prevalence of musculoskeletal discomfort was identified, particularly in the neck, lower and upper back, legs, and knees. These conditions were closely associated with improper working postures, manual handling of loads, and the high physical demands intrinsic to healthcare activities. A significant correlation was found between the duration of the workday and the perceived level of physical effort, suggesting that prolonged shifts without adequate rest periods increase bodily strain.
