According to the 2018 study, Occupational Injury Among Janitors—Injury Incidence, Severity, and Associated Risk Factors: Injury and work-related pain is an ongoing problem for janitors and cleaning professionals, as earlier noted by Woods and Buckle in 2000, in which 74% of janitors experienced job-related pain over a one-year period, which paralleled 2018 findings in which 66% of janitors had pain issues.

A study in Las Vegas found that 75% of janitors had job-related pain; while 82% of cleaning professionals in a Texas hospital experienced work-related pain during a 12-month period.

Major types of injury included sprains, strains, bruises, and fractures; and involved necks, backs, shoulders, arms, elbows, wrists, hands, legs, and knees.
