OBJECTIVE: To determine the prevalence of self-perceived emotional distress and its relation to work-related musculoskeletal disorders (WRMSDs) in nurses.
METHODS: A self-administered questionnaire survey was carried out on 660 female nurses working in public hospitals in the Klang Valley, Malaysia. The validated Malay version of the standardized Nordic musculoskeletal questionnaire (M-SNMQ) was used to identify the annual prevalence of WRMSDs; perceived emotional distress was assessed using the validated Malay short version, depression, anxiety, and stress (M-DASS) instrument. In addition, socio-demographic and occupational profiles of the participants were considered. Factors associated with WRMSDs were identified using logistic regression analysis.
RESULTS: A total of 376 nurses completed the survey (response rate 83.3%). 73.1% of the nursing staffs experienced WRMSDs in at least one anatomical site 12 months prior to the study. 75% of nurses expressed emotional distress. Of these, over half also reported anxiety and stress. Multiple logistic regression analysis showed that stress and anxiety significantly increased the risk of WRMSDs by approximately twofold.
CONCLUSION: There were significant associations between emotional distress and WRMSDs. Future longitudinal studies are therefore needed to investigate and identify the sources of emotional distress (non-occupational and occupational) to be used to establish preventive strategies to reduce the risk of WRMSDs.
METHODS: A cohort of 611 male Malaysian Army recruits were recruited and followed up at 3 and 6 months. Pain catastrophising, MSD, sociodemographic and work factors were measured using a self-administered questionnaire, and MSI incidence was retrieved from the medical records. Multivariable fixed effects regression was used to model the cumulative incidence of MSD and MSI.
RESULTS: Approximately 12% of the recruits were diagnosed with incident MSI and 80% reported incident MSD. Higher pain catastrophising at baseline was associated with higher 6 month MSD risk (adjusted OR (aOR) 1.6 per 1 SD increase of Pain Catastrophising Scale (PCS) scores; 95% CI 1.2 to 2.0), and longitudinally associated with MSD incidence (aOR 1.2, 95% CI 1.1 to 1.4). Pain catastrophising was not associated with MSI incidence (aOR 1.0, 95% CI 0.8 to 1.3). The association between pain catastrophising and self-reported MSD was stronger among recruits with self-reported past injury (p for interaction <0.001).
CONCLUSIONS: Pain catastrophising was able to predict symptomatic MSD, and not physician-diagnosed MSI, and these findings are directly related to individual health beliefs. Pain catastrophising has a greater influence on how military recruits perceived their musculoskeletal conditions during training, and efforts to reduce pain catastrophising may be beneficial.
