Abstract

Insights

Municipal waste loading significantly increases the risk of musculoskeletal disorders (MSDs) and disabilities, particularly affecting the low back, hip, thigh, upper back, and shoulder. Psychosocial factors also contribute to these risks.

Area of Science:

  • Occupational health
  • Public health
  • Epidemiology

Background:

  • Musculoskeletal disorders (MSDs) and related disabilities pose a significant health burden.
  • The occupation of municipal waste loading involves strenuous physical activity, raising concerns about potential health impacts.

Purpose of the Study:

  • To evaluate the association between municipal waste loading and the incidence of MSDs and disabilities.
  • To identify key risk factors contributing to MSDs and disabilities in waste loaders.

Main Methods:

  • A cross-sectional case-control study was conducted in Mumbai, comparing 180 municipal waste loaders with 180 controls.
  • The Standardized Modified Nordic questionnaire assessed MSDs and disabilities over the past 12 months.
  • Propensity Score Matching (PSM) was employed to analyze the occupational impact on MSDs and disabilities.

Main Results:

  • Waste loaders exhibited a significantly higher prevalence of MSDs and disabilities, especially in the low back, hip/thigh, upper back, and shoulder regions.
  • PSM revealed higher MSD rates for hip/thigh (22%), low back (19%), shoulder (18%), and upper back (15%) among loaders.
  • MSD-related disabilities were also significantly elevated in waste loaders for low back (20%), hip/thigh (18%), upper back (13%), and shoulder (8%).

Conclusions:

  • The municipal waste loading occupation is a significant risk factor for developing MSDs and related disabilities.
  • Preventive and curative interventions are crucial to mitigate the health consequences for waste loaders.

Disorders of the Skeletal Muscle

The clinical conditions affecting the skeletal muscle tissue are broadly categorized as musculoskeletal and neuromuscular disorders.
Musculoskeletal disorders
Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups. Common injuries include sprains, fractures, and muscular strains, often resulting from...
