Individual and work-related risk factors for musculoskeletal pain among computer workers in Nigeria

ABSTRACT

We investigated the prevalence of musculoskeletal pain (MSP) and the association of 1-month prevalence with individual and work-related factors among commercial typists in Enugu. Participants responded to a questionnaire about occurrences of MSP and a 75.6% (242/320) response rate was achieved. Prevalence was summarized in frequencies and percentages while associations between MSPs and risk factors were explored using chi-square. MSP was most common in the low back (58.3%), and low back pain limited 51.7% from activities between 1 and 30 days. Advancing age was significantly associated with MSP in the low back (x² = 19.885; p = .001), neck (x² = 28.309; p < .001), shoulder (x² = 13.122; p = .011), but not wrist/hand (p = .075). Working 1–5 years in this job was associated with increasing prevalence of MSP in all body regions studied. Lesser job control was associated with increased prevalence of wrist/hand pain. Prevalence of MSDs among computer operators in Enugu, Nigeria, is high and highlights the importance of workplace intervention.
