Sintomas osteomusculares e qualidade de vida : uma comparação entre trabalhadores administrativos e de produção de uma indústria agroavícola
Resumo
Work-related musculoskeletal disorders are diseases caused due to musculoskeletal
injuries. Moreover, they are the most registered group of occupational diseases in
Brazil. Modern industries are favourable environments for the development of
musculoskeletal disorders due to the physical and psychosocial demands imposed
by the economy. Musculoskeletal symptoms may impairs daily activities, cause work
leaves and prejudice quality of life. This study justifies itself based in the need in
increasing the investigations about the musculoskeletal symptom manifestation in
industry and its interference in quality of life, since the magnitude of the occurrence
musculoskeletal disorders in workers is still not well-known in Brazil. Aim: To analyse
the prevalence of musculoskeletal symptoms in production and administrative
workers in an industry. Objectives: verify the socio-demographic and occupational
profile of both studied groups; identify the occurrence of association between pain
and socio-demographic and occupational variables; identify the prevalence of pain in
the studied body segments; identify the association between intensity and location of
pain comparing the two studied groups; identify the associations between quality of
life domains and musculoskeletal pain intensity in each assessed body segment.
Material and Methods: This was a correlational, descriptive and cross-sectional study
that used quantitative analysis. Assessment tools: socio-demographic and
occupational assessment tool, Nordic musculoskeletal questionnaire (NMQ), numeric
scale of pain to assess the perceived intensity of pain and WHOQOL-bref to assess
quality of life. The data collection occurred in an industry of the poultry sector, of a
city in the country side of São Paulo state, Brazil. The study was approved by
UFSCar Ethics Committee. Results: The sample was composed by 178 workers (154
production workers and 24 administrative workers). Mean age was lower than 30
years in both groups, with prevalence of women and single people only in production
sector. The prevalence of musculoskeletal pain was higher than 85% in both sectors.
The neck was the body segment with higher prevalence of pain in administrative
workers. Production workers reported more intense pain in upper and lower back
when compared to administrative workers. Women from production sector had
chances increased in 2.9 times in presenting pain when compared to men. The mean
value in quality of life domains were moderate, in which the physical domain were
more affected in administrative workers when compared to production workers. The
correlations between intensity of pain and quality of life domains were not significant
in most comparisons. Physical domain presented positive correlations with neck,
shoulders and hip pain in production workers. Final considerations: Musculoskeletal
pain was highly prevalent in workers from a poultry industry, in both administrative
and production sectors. The most affected areas in workers from the administrative
sector were neck, lower back and upper back, whilst lower back, shoulders and
upper back were the most affected in production workers. Moreover the most
prevalent pain in administrative workers was in the neck. The referred pain in almost
all body segments were rated as moderate by most of workers. Workers from
production sector referred more intense pain in upper and lower back when
compared to administrative workers. The mean values in quality of life domains were
moderate, and the most impaired domain, in both sectors, was the physical one. The
correlations between pain intensity and perceived pain in each body segment
compared with quality of life domains in both sectors were not significant in almost all
comparisons.
