Background: Work-related musculoskeletal disorders (WMSDs) have been documented among various occupational groups in Nigeria. However, there is limited data on the prevalence of WMSDs among call center operators (CCOs).

Objective: To determine the prevalence of WMSDs among CCOs in Nigeria and to explore the extent to which these discomforts impact the daily work activities of the respondents.

Methods: 374 respondents who were randomly selected from 4 telecommunication companies in Lagos State, Nigeria, participated in this study. They were asked to complete a pre-tested questionnaire designed to capture the prevalence, impact and associated risk factors of WMSDs among CCOs.

Results: 42% and 65.2% of respondents experienced at least one WMSDs in the past 7 days, and 12 months, respectively. Women and CCOs who received calls with hand-held phones rather than headsets reported more discomforts during both 7 days and 12 months periods. Neck, shoulder, upper back, and lower back were the most affected areas during past 7 days and 12 months. Discomforts in the neck, low back, and knees prevented most of the respondents from performing their daily work.

Conclusion: WMSDs have a serious impact on the daily job activities of the CCOs in Nigeria.
