ABSTRACT
Background and objective Low back pain (LBP) is a significant and prevalent musculoskeletal disorder associated with the workplace that impacts individuals, families, communities, healthcare systems, and companies. Although LBP prevalence and risk factors have been studied in various professional categories in Saudi Arabia, there is no data on the prevalence of LBP among office workers and related risk factors. This study aimed to determine the prevalence of LBP among office workers in Saudi Arabia and identify major risk factors. Methodology This cross-sectional study was conducted among office workers in Saudi Arabia of both genders aged over 18 years living in five geographical regions: Central, Western, Southern, Eastern, or Northern. A self-administered questionnaire was distributed among office workers using an online survey. The questionnaire comprised sociodemographic characteristics, the prevalence of work-related LBP, and work-related characteristics. Results Among 604 office workers, 51.7% were males and 43.5% were aged between 18 and 30 years old. The prevalence of work-related LBP in this study was 59.9%. Independent risk factors for LBP include being overweight or obese, sleep disturbance, previous history of back trauma, increasing years of working in the office, changes made to workstation/work habits to reduce the risk of LBP, and frequent work stress. Protective risk factors for LBP include regular physical exercise and satisfaction with the current job. Conclusions LBP was widely prevalent among office workers in Saudi Arabia. Office workers with elevated body mass index (BMI) who had a previous history of back trauma and had sleep disturbance or work stress in the past month were at significant risk for LBP. Occupational health and safety programs are vital for building ergonomically safe working conditions, and regular physical exercise promotion could alleviate the risk of LBP at work.
