Relationships among musculoskeletal disorders, job stress, and health-realted quality of life in parcel delivery workers in Korea = 근골격계 질환과 직무스트레스 및 삶의 질 간의 관련성: 택배업 종사자를 대상으로

국문 초록 (Abstract)

본 연구는 택배업 종사자의 근골격계 질환, 직무 스트레스 및 건강관련 삶의 질(health-related quality of life, HRQoL) 간의 관련성을 규명하고, 작업 특성에 따른 분석을 통해 택배 종사자의 건강 문제를 해결하는데 필요한 기초자료를 제공하고자 수행되었다. 본 연구는 단면연구로 설계되었으며, 2025년 3월부터 6월까지 경기도 소재 H 택배회사의 여러 지점에서 근무하는 택배 종사자 289명을 대상으로 하였다. 연구 목적과 절차를 충분히 설명한 후 서면 동의를 받은 뒤 근골격계 질환, 직무 스트레스 및 HRQoL에 관한 자기기입식 설문조사를 실시하였으며, 수집된 자료는 SPSS 28.0 프로그램을 사용하여 분석하였다(유의수준 p < .05). 연구 결과, 광범위한 통증을 호소하는 집단은 단일 통증 집단에 비해 직무 스트레스는 높고 삶의 질 수준은 유의하게 낮았으며, 주 6~7일 근무 집단은 주 5일 근무 집단보다 직무 스트레스가 높고 삶의 질이 낮은 것으로 나타났다. 또한 직무요구도, 신체적 업무환경, 대인관계 갈등은 신체적·정신적 건강에 부정적인 영향을 미치는 공통 위험요인으로 확인되었다. 이러한 결과는 택배업 종사자의 근골격계 질환을 완화하고 삶의 질을 향상시키기 위해 근무일 조정, 작업환경 개선, 직무요구관리, 심리사회적 지원을 포함한 다차원적 접근이 필요함을 시사한다.

다국어 초록 (Multilingual Abstract)

This study aimed to examine the relationships among musculoskeletal disorders, job stress, and health-related quality of life (HRQoL) in parcel delivery workers. Analyses based on working characteristics were performed to provide valuable data for resolving the health issues of the parcel delivery workers .
This cross-sectional study was perfomed from March to June 2025 among 289 parcel delivery workers employed at several branchs of Parcel Delivery Company H in Gyeonggi Province, South Korea. After obtaining written informed consent, self-administered questionnaires covering musculoskeletal disorders, job stress, and HRQoL were collected. Data were analyzed using SPSS 28.0 with a significance level set at p < .05. Job stress and quality of life were significantly lower in the widespread pain group than in the single pain group. The group working 6–7 days per week had higher job stress and lower quality of life compared with the group working 5 days per week. Job demands, physical environment, and interpersonal conflict were found to be common risk factors negatively affecting both physical and mental health.
A multidimensional approach integrating workday adjustments, working environment improvements, job demand management, and psychosocial support is necessary. It can alleviate musculoskeletal disorders and improve the parcel delivery workers' quality of life.
