Abstract

Introduction: Studies in developed countries has shown significant ergonomics concern in wholesale and retail sector which were detrimental to the industry as a whole. Primarily, musculoskeletal disorders has been the most commonly reported disabilities which not only affects the employees but also the employers as productivities became a major concern. Specifically, hypermarkets employee requires employees to carry out a broad range of manual handling and repetitive task which includes arrangement of products on the shelves repeatedly, lift, push or pull heavy loads, or standing and sitting for a long time with minimal movement, all of which increase the risk of developing MSDs. However, based on literature search, there is a lack of data available on the prevalence of MSDs among hypermarkets workers in Malaysia which shows the lack and underreporting cases of MSDs in this sector. Objectives: To determine the factors associated with the prevalence of musculoskeletal disorders (MSDs) among hypermarkets workers in Klang Valley. Methodology: This was a cross-sectional study conducted among hypermarket workers in Klang Valley. The main research instruments used in this study was self- administered questionnaire which consists of six sections: sociodemographic background, medical history, social lifestyle, occupational history, modified Nordic Musculoskeletal Questionnaire (NMQ) and ergonomics risk factors. Results and Discussion: A total of 261 employees have participated in this study. From the data obtained, the prevalence of self-reported MSDs (total in any body part) among the respondents was 81.6% highest being the lower back (42.5%) followed by the upper back (35.2%), the neck (25.3%) and shoulder (25.3%). It was found that age, gender, education, marital status, children, physical activity, and its frequency, working experience, static and sustained posture, lifting and lowering loads, handling loads in seated position, temperature and ventilation were significantly associated with the prevalence of MSDs among the respondents with p<0.05. From the multivariate analysis, total MSDs was mainly contributed by the children factor (OR=11.745, 95% CI=2.772 - 49.764). Conclusion: This study showed that most of the hypermarket workers have developed MSDs in the past 12 months. There are multifactorial factors in causing MSDs that were self-reported by the workers. Keywords: ergonomics, musculoskeletal disorders, ergonomic risk factors, hypermarket workers
