Neck and upper extremity musculoskeletal problems in cosmetologists caused by work-related ergonomic risk factors in Denizli, Turkey

Abstract

BACKGROUND: Work-related musculoskeletal disorders (MSDs) of the neck and upper limbs are a common health problem among cosmetologists. Hairdressing requires bending, twisting, static postures, prolonged standing, repetitive motions, and vigorous movements of the hands and fingers. In order to determine the proper ergonomic measures, identifying the factors and hairdressing jobs that increase the risk of work-related neck and upper limb disorders is needed. OBJECTIVE: The objective of this study was to determine the prevalence of MSDs in the neck and upper extremities of cosmetologists and to investigate the association with ergonomic risk factors and hairdressing work. METHODS: The cross-sectional study was conducted on cosmetologists in Denizli, Turkey province (n = 504). Data collected through a survey included questions on sociodemographic characteristics, work organization, equipment, and hairdressing work, items on work posture, the Extended Nordic Musculoskeletal Questionnaire, and the Demand-Control-Support Questionnaire. Work posture in hairdressing was assessed using the Rapid Upper Limb Assessment (RULA). RESULTS: The prevalence of MSDs of the neck and upper limbs in the previous twelve months ranged from 7.7–55.8%. There was high, or very high, risk in 56.1% of work postures, and the median RULA score was 5.0 (4.0–6.0). The significant predictors of pain were work experience, gender, marital status, risk perception, awkward posture, psychological demand, and hair coloring. CONCLUSION: It is necessary to take control measures in hairdressing salons promptly to adopt more suitable working posture and to design workplaces ergonomically.
