Avaliação da influência de riscos psicossociais e físicos no desenvolvimento de DORT’s em trabalhadores da indústria de calçados

Abstract

Work-related musculoskeletal disorders (WRMDs) have affected workers in the workforce. There are not many studies on psychosocial factors in worker health. Knowing, the article aims to evaluate psychosocial factors in the development of musculoskeletal disorders in workers of a footwear industry, through a set of studies performed with 267 workers in this industry. We applied an individual and face-to-face questionnaire to collect the worker's perceptions about psychosocial factors and the symptoms of WRMDs. To assess psychosocial factors, the relationship with WRMD symptoms in the middle coast and low back region was through an ordinal logistic regression analysis using the Odds Ratio (OR). It was identified that ‘low social support from supervisor’ as a risk factor for the middle back with 17.11% (OR = 1.1711, 95% CI 1.0540-1.3012) and low back with 25.99% (OR = 1, 2599, 95% CI 1.1308-1.4037); ‘inadequate posture’ also increased the chance of symptoms on the middle back at 55.52% (OR = 1.5552; 95% CI: 1.1406 - 2.1205) and low back at 59.55% (OR = 1.5955; % 1,1794-2,1584); already ‘Job Dissatisfaction’ was shown to be the major risk factor, increasing the chance of low back symptoms in 93.97% (OR = 1.93,97, 95% CI, 1.2020-3.1303); the ‘length of service’ increased the chance of symptoms on the middle back by 0.51% (OR = 1.0051, 95% CI, 1.0021- 1.0082). It was concluded that psychosocial factors can influence WRMDs with similar importance to physical factors, increasing the chance of WRMD symptoms in the back and lower back of workers.
