Musculoskeletal disorders and stress among footwear industry workers.

Abstract

Manufacturing footwear requires intense manual labor and high repetitions with low variability in function that may lead to musculoskeletal disorders (MSD) symptoms and psychological stress. To evaluate a potential association between musculoskeletal disorders (MSD) and perceived stress among footwear industry workers. The Nordic General Questionnaire (NGQ) and the Perceived Stress Scale (PSS-10) were completed by 357 footwear industry workers. The association between MSD and perceived stress was evaluated using the Chi-Square test and Odds Ratios along with their 95% Confidence Interval (95% CI) were calculated. The twelve-month prevalence of MSD symptoms among the respondents was 66% (n = 236) and the symptoms were significantly associated with perceived stress (p = 0.002, OR: 10, 95% CI: 1.7 to 60.6). The seven-day prevalence of MSD symptoms was 33% and the symptoms were also significantly associated with perceived stress (p = 0.001, OR: 2.7, 95% CI:0.8 to 9.3). The association between perceived stress and MSD symptoms indicates a strong association between MSD symptoms and perceived stress levels. Considering that these problems are important determinants of worker's health, a combined approach to reduce both stress and MSD symptoms is necessary for prevention and health promotion in the footwear industry.
