The Influence of Ergonomic Risk on Work Performance: Low Back Pain as Mediator in Office Workers

Abstract

Introduction:In today's modern era characterised by rapid advances in technology and digital transformation, office workers are facing new challenges in their working patterns. They are increasingly trapped in a sedentary lifestyle, characterised by prolonged sitting during working hours. One of the most common ergonomic risks found in office workers is complaints of the lower back.
Objectives:The aim of this study was to look at the influence of ergonomic risks such as work posture and lighting intensity on work quality, with Low Back Pain (LBP) complaints as mediators.
Methods:Quantitative research with an analytical observational approach using a cross-sectional design. Data collection from 110 respondents used a work quality questionnaire, posture assessment using Rapid Entire Body Assessment, lighting measurement using a lux meter, and pain scale measurement using the Numerical Rating Scale.
Results:The results showed that there was a significant direct influence between work posture on work quality (p=0.000), (f=0.396) showing a high influence, while lighting intensity had no significant direct effect on work quality (p=0.058). Meanwhile, through the analysis of the indirect influence with LBP complaints as a mediator, there was a significant influence between work posture on work quality (p=0.000), (z-sobel= -3.644). Meanwhile, the intensity of lighting also had a significant influence on the quality of work with LBP complaints as mediator (p=0.042), (z-sobel= 2.185).
Conclusions:LBP complaints have a significant influence in mediating the influence of work posture and lighting intensity on work quality.
