Musculoskeletal injury, functional disability, and health-related quality of life in aging Mexican immigrant farmworkers.

Migrant and seasonal farmworkers are at high risk for musculoskeletal and other occupational injuries. Although persons aged 40-80 years account for 40 % of all US farmworkers and as many as 50 % in certain regions, little is known about their occupational health issues. The current study examined work-related persistent musculoskeletal injuries (PMIs) and their association with clinical and functional indicators of disability and health-related quality of life (HRQOL) in 177 middle-aged and elderly US-Mexico border farmworkers. At interview, 68 % reported current PMI pain; 51 % had pain at multiple sites. PMI pain was associated with increased shoulder, knee, and lower extremity dysfunction and reduced HRQOL scores. However, fewer than 25 % of injured participants received any conventional medical treatment. The study results indicated that work-related PMIs, especially multiple PMIs, caused significant functional impairment, disability, and poorer HRQOL, adversely affecting the ability of the aging farmworkers to perform work, self-care, and other daily activities.
