Hubungan Durasi Kerja Dan Postur Kerja Dengan Keluhan Nyeri Punggung Bawah Pada Pekerja Kantoran

Low back pain (LBP) is one of the most common health problems among office workers, especially those with long working hours and unergonomic sitting postures. Many work responsibilities must be completed so that the time to rest and return to work is uncertain. This study aims to analyze the relationship between work duration and work posture with NPB complaints in office workers and the factors that influence them. The method used is literature review by reviewing 15 journals that discuss the risk factors of NPD. The results of the analysis showed that work duration exceeding 8 hours and poor sitting posture had a significant correlation with an increased risk of NPD. In addition, several other factors contribute to the incidence of NCD, such as age, workload, and work attitude. Older workers are at higher risk of NBP due to reduced bone elasticity and muscle stability. Heavy workloads and long working hours cause muscle fatigue, which increases complaints of NBP. Unergonomic work attitudes, such as bending or sitting that are not ideal, also increase the risk of musculoskeletal disorders. Prevention can be done through the application of ergonomic principles and good working time management to reduce musculoskeletal risks.
