Prevalence of low back pain and work-related musculoskeletal disorders in Brazilian domestics and cleaners: 2013 and 2019 National Health Survey

Abstract

Objectives: Determine the prevalence and predictive factors of low back pain and workrelated musculoskeletal disorders in Brazilian domestics and cleaners. Methods: This population-based cross-sectional study collected data from the 2013 and 2019 National Health Survey, involving a total of 8,160 workers. The prevalence of low back pain and work-related musculoskeletal disorders was calculated based on adjusted prevalence ratio (PR) by Poisson regression and 95% confidence interval (95%CI). Results: The prevalence of low back pain was 19.1% in 2013 and 20.6% in 2019; while musculoskeletal disorders prevalence was 2.2% in 2013 and 2.4% in 2019. Low back pain was associated with the elderly (PR: 1.74; CI95%: 1.44-2.09), poor or very poor self-rated health (PR: 2.10; CI95%: 1.76-2.50), holding a prepaid health plan (PR: 1.27; CI95%: 1.09-1.47) and moderately severe (PR: 2.27; CI95%: 1.84-2.80) or severe (PR: 2.32; CI95%: 1.77-3.04) depressive symptoms. Musculoskeletal disorders affected less domestics (PR: 0.53; CI95% 0.40-0.72); and were associated to women (PR: 2.50; CI95%: 1.34-4.66), adults (40-59 years) (PR: 1.79; CI95%:1.26-2.55), holding a prepaid health plan (PR: 2.31; CI95%: 1.63-3.26) and the presence of moderately severe (PR: 4.00; CI95%: 2.34-6.86) or severe (PR: 3.63; CI95%: 1.77-7.46) depressive symptoms. Conclusion: Domestics and cleaners Brazilian need interventions and health improvementsgiven the prevalence of low back pain and musculoskeletal disorders as well as their association with depression.
