RESUMO
PURPOSE: To examine the impact of pre-existing anxiety and depression disorders on return to work (RTW) using a phase-based approach. METHODS: Accepted lost-time workers' compensation claims for upper limb or spine strain or sprain from 2009 to 2013 were extracted for workers in the Canadian province of British Columbia (n = 78,186). Pre-existing anxiety and depression disorders were identified using health claims data. Probability of RTW following a first or second work lost-time episode was analyzed using Prentice, Williams and Peterson models for recurrent events (common hazards ratios (cHR)). Probability of a first lost-time recurrence was analyzed using Cox models (HR). All models included two years of follow up and were stratified by gender. RESULTS: For men, anxiety alone (cHR = 0.90, 95% CI: 0.85 to 0.94) or comorbid with depression (cHR = 0.95, 95% CI: 0.92 to 0.99) was significantly associated with a lower probability of RTW, and comorbid anxiety and depression with a higher probability of recurrence (HR = 1.29, 95% CI: 1.13 to 1.48). In women, comorbid anxiety and depression was significantly associated with a lower probability of RTW (cHR = 0.96, 95% CI: 0.93 to 0.99) and a higher probability of recurrence (HR = 1.15, 95% CI: 1.04 to 1.28); and anxiety alone with a higher probability of recurrence (HR = 1.25, 95% CI: 1.09 to 1.43). There was little evidence that depression alone was associated with RTW or recurrence. CONCLUSIONS: Workers with a pre-existing anxiety disorder may require additional supports both during lost-time and after initial RTW.

OBJECTIVE: To examine the prevalence and risk factors for medically treated anxiety and depression disorders among men and women with musculoskeletal strain or sprain work injury in British Columbia, Canada. METHODS: A retrospective population-based cohort of accepted workers' compensation lost-time claims from 2000 to 2013 was constructed using linked administrative health data. Anxiety and depression disorders were identified using diagnoses from physician, hospital and pharmaceutical records. The 1-year period prevalence was estimated for the year before and the year after injury. Sociodemographic, clinical and work-related risk factors for prevalent and new onset anxiety and depression disorders were examined using multinomial regression. RESULTS: 13.2% of men and 29.8% of women had medically treated anxiety, depression or both in the year before injury. Only a slight increase (~2%) in the prevalence of these disorders was observed in the year after injury. Somatic and mental comorbidities were both strong risk factors for pre-existing and new onset anxiety and depression for both men and women, but these relationships were stronger for men. CONCLUSION: Anxiety and depression disorders including those from prior to injury are common in workers with musculoskeletal strain or sprain and are associated with a complicated clinical profile. Gender-sensitive and sex-sensitive mental healthcare is an important consideration for work disability management.
RESUMO
OBJECTIVE: The aim of this study was to examine the impact of anxiety and depression disorders on sustained return to work (RTW) for men and women with musculoskeletal strain or sprain. METHODS: Accepted lost-time claims for spine and upper-extremity strain or sprain were extracted for workers in the Canadian province of British Columbia from 2009 to 2013 (N=84 925). Pre-existing and new onset anxiety and depression disorders were identified using longitudinal health claims data. Probability of sustained RTW was analyzed using Cox proportional hazards models, stratified by gender and adjusted for potential confounders. RESULTS: For pre-existing disorders, compared to men with no anxiety and no depression, men with anxiety only [hazard ratio (HR) 0.88, 95% confidence interval (CI) 0.84-0.93], depression only (HR 0.94, 95% CI 0.89-1.00), and anxiety and depression (HR 0.93, 95% CI 0.90-0.97) had lower probabilities of sustained RTW in adjusted models. The same direction of effect was found for women, but anxiety only had a smaller effect size among women compared to men (HR anxiety only 0.95, 95% CI 0.92-0.99; HR depression only 0.98, 95% CI 0.93-1.03, HR anxiety and depression 0.94, 95% CI 0.91-0.97). Among men and women, new onset disorders were associated with lower probability of sustained RTW and the effect estimates were larger than for pre-existing disorders. CONCLUSIONS: Findings suggest that workers' compensation benefits and programs intended to improve RTW after musculoskeletal injury should take pre-existing and new onset anxiety and depression disorders into consideration and that gender-sensitive work disability strategies may be warranted.

OBJECTIVES: Policy and legislation that prohibits workplace harassment and discrimination, including that which is disability related, has been in place in Canada for many years. The study objective was to examine associations between disability and workplace harassment and discrimination in the current Canadian context, as well as the intersection of disability with age, gender, and ethnicity. METHODS: Cross-sectional data from the 2014 Canadian Public Service Employee Survey was analyzed (n = 175,742) using logistic regression to investigate the relationship between self-reported disability and workplace harassment and discrimination in the last 2 years. Age, gender, and ethnicity were included as potential confounders and effect modifiers. Additive and multiplicative effect modifications were examined using linear binomial and logistic regression, respectively. RESULTS: Overall, 18 and 8% of the sample of Canadian public service employees reported workplace harassment and discrimination, respectively. The prevalence was higher for workers with disability (37 and 26%). Disability was significantly associated with an increased odds of harassment (odds ratio (OR) = 2.80; 95% confidence interval (CI), 2.68-2.92) and discrimination (OR = 4.97; 95% CI, 4.72-5.23) in models adjusted for confounders. Significant positive additive effect modification was observed for (1) age in the harassment and discrimination models and (2) ethnicity in the discrimination model. CONCLUSION: Findings from a 2014 census of the Canadian federal public service suggest that additional efforts are needed to address workplace harassment and discrimination beyond those already in place. Consideration should be given to workers with disability, as well as the intersectional impacts for older workers, visible minorities, and Aboriginal peoples.
