BACKGROUND 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. OBJECTIVE To evaluate a potential association between musculoskeletal disorders (MSD) and perceived stress among footwear industry workers. METHODS 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. RESULTS 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. CONCLUSION 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.
