Ayanniyi O, Ukpai BO, Adeniyi AF - BMC Musculoskelet Disord (2010)

Bottom Line: This study compared the prevalence of SRMS between computer and non computer users and assessed the risk factors associated with SRMS.The prevalence of SRMS was significantly higher in the computer users than the non computer users both over the past 7 days (chi2 = 39.11, p = 0.001) and during the past 12 month durations (chi2 = 53.56, p = 0.001).Computer use may explain the increase in prevalence of SRMS among the computer users.

ABSTRACT

Background: Literature abounds on the prevalent nature of Self Reported Musculoskeletal Symptoms (SRMS) among computer users, but studies that actually compared this with non computer users are meagre thereby reducing the strength of the evidence. This study compared the prevalence of SRMS between computer and non computer users and assessed the risk factors associated with SRMS.

Methods: A total of 472 participants comprising equal numbers of age and sex matched computer and non computer users were assessed for the presence of SRMS. Information concerning musculoskeletal symptoms and discomforts from the neck, shoulders, upper back, elbows, wrists/hands, low back, hips/thighs, knees and ankles/feet were obtained using the Standardized Nordic questionnaire.

Results: The prevalence of SRMS was significantly higher in the computer users than the non computer users both over the past 7 days (chi2 = 39.11, p = 0.001) and during the past 12 month durations (chi2 = 53.56, p = 0.001). The odds of reporting musculoskeletal symptoms was least for participants above the age of 40 years (OR = 0.42, 95% CI = 0.31-0.64 over the past 7 days and OR = 0.61; 95% CI = 0.47-0.77 during the past 12 months) and also reduced in female participants. Increasing daily hours and accumulated years of computer use and tasks of data processing and designs/graphics significantly (p < 0.05) increased the risk of reporting musculoskeletal symptoms. Over the past 7 day duration, the neck (33.9%) and low back (11.4%) had highest prevalence of SRMS for the computer and non computer users respectively.

Conclusion: The prevalence of SRMS was significantly higher in the computer users than the non computer users and younger age, being male, working longer hours daily, increasing years of computer use, data entry tasks and computer designs/graphics were the significant risk factors for reporting musculoskeletal symptoms among the computer users. Computer use may explain the increase in prevalence of SRMS among the computer users.

Figure 2: Twelve month prevalence of SRMS among computer and non computer users by anatomical distribution.

Mentions: The mean age of the participants were 29 ± 4.87 (for computer users) and 31 ± 6.23 (for non computer users) and most of them were males (57.6%) (Table 1). Table 1 also shows a significant difference (p = 0.001) in the amount of time spent daily on the computer by the two groups. Comparing the prevalence of SRMS between the computer and non-computer users over the past 7 days revealed a significantly higher prevalence of SRMS in the computer users than the non computer users (χ2 = 39.11, p = 0.001, prevalence ratio 2.03) as seen in table 2. The difference in the prevalence of SRMS during the past 12 months between the computer and the non computer users was significant as well (χ2 = 53.56, p = 0.001, prevalence ratio 2.7) with higher prevalence in the computer users. In terms of the anatomical distribution of SRMS over the past 7 day duration, the neck was mostly reported as the site of SRMS in the computer users (33.9%) while low back was the most prevalent (11.4%) for the non computer users (figure 1). During the past 12 months for both groups (figure 2), the neck was the site with the most prevalent SRMS (64.0% and 33.9% for the computer and non computer users respectively). Over the past 7 days, the ankle/feet were least reported (6.4%) site of MSD in the computer users while the elbow was least reported (3.0%) in the non computer users. During the past 12 months in the computer users, the low back was next in prevalence to the neck and similarly, the least SRMS was reported in the ankles/feet (13.1%). For the non computer users however, hips/thighs were the least reported site of SRMS (7.6%) during the past 12 month duration.
