Background: Low back pain (LBP) is a very common health problem amongst the general population and a major cause of disability that affects work performance and well-being. Healthcare workers (HCWs) are especially at risk of developing LBP because of physical and emotional factors. Little is known about the burden of LBP in Cameroon. Objective: To determine the prevalence of low back pain and identify its associated factors among healthcare workers. Methods: A cross-sectional study using a self-administered questionnaire was conducted among healthcare workers in the Yaoundé Central Hospital and the Yaoundé University Teaching Hospital. The questionnaire collected data regarding recent, past year and lifetime occurrences of LBP, socio-demographics and work conditions. Data were analysed using IBM Statistical Package for Social Sciences (SPSS) version 26. Results: A total number of 268 HCWs participated in the study, including 197 (73.5%) females and 71 (26.5%) males. The mean age of the study participants was 40.60 ± 8.38 years (extremes of 20 and 65 years). The lifetime, annual, and point prevalences of LBP among the participants were 67.5% (CI: 61.6 - 73.1), 61.5% (CI: 55.6 - 67.1) and 35.7% (CI: 29.7 - 41.5) respectively. Multivariate analysis confirmed a moderate stress level, a sedentary lifestyle, working in the medicine and specialities department, lifting heavy objects and bending to work as associated factors to LBP. Most sufferers had a minimal functional disability (65.7%) while 34.3% had a moderate to severe disability. Conclusions: Healthcare providers have a considerably high prevalence of low back pain. Factors associated with LBP found in this study were similar to those widely recognized in the literature. A substantial proportion of healthcare providers are suffering from functional disability associated with low back pain, affecting their social and work lives. There is a need for multilevel interventions to prevent and control low back pain in this highly vulnerable occupational group.
