목적: 작업관련 근골격계 증상 유소견자들의 증상 신체부위에 따른 결근ㆍ조퇴 현황과 관련요인을 파악하여 사업장 보건관리의 기초자료로 활용하고자 한다. 방법: 2007년 1월부터 12월까지 인천지역 116개 사업장, 4,975명의 근로자를 대상으로 하였으며, 이 대상자들 중에서 신체부위별로 NIOSH 기준에 해당되는 작업 관련 근골격계 증상 유소견자를 선별하여 최종분석 대상자로 하였다. 구조화된 자기기입식 설문지를 이용하여 신체 부위별 근골격계 증상, 결근ㆍ조퇴 여부, 사회 일반적 특성, 작업관련 특성 등을 조사하였다. 결과: 작업관련 근골격계질환 증상 유소견자들의 신체 부위별 결근ㆍ조퇴율은 허리에서 가장 높았고(14.9%), 대체적으로 남성이 여성보다 높았으며 생산직이 사무직 보다 높은 것으로 나타났다. 신체 부위별로 단변량 분석에서 유의한 차이를 보인 변수들을 각각 보정하였을 때, 통증강도가 높은 군의 결근ㆍ조퇴에 대한 교차비(OR)는 각각 목(4.361), 어깨(4.008), 허리(2.956), 팔/손목(3.151), 다리/발(3.093)로 나타났고 통계적으로 유의하였다. 결론: 작업관련 근골격계 증상 유소견자들의 증상 신체부위에 따른 결근ㆍ조퇴율은 허리에서 가장 높았고, 대체로 통증의 강도가 결근ㆍ조퇴율에 많은 영향을 주고 있으며, 낮은 강도에서도 결근ㆍ조퇴율이 높은 허리 부위는 조기 개입의 필요성이 있다고 판단된다.
Objectives: The purpose of this study was to identify current status of sickness absence and early leaves from work as a result of work-related musculoskeletal symptoms. Method: From January to December in 2007, 4,975 workers were recruited into this study and surveyed over this time period; workers came from 116 small and medium sized companies in Incheon. Among the study populations, only those who met the NIOSH criteria for work-related musculoskeletal symptoms on each symptom locations were included in the final analysis. The survey used a structured self-administered questionnaire, which asked questions about musculoskeletal symptoms regarding locations, sickness absences and early leaves from work. Other information gathered from participants included sociodemographical characteristics, and work-related characteristics. Results: The rates of sickness absences and early leaves in each symptom locations were highest (14.9%) among workers with waist symptoms. Men had higher rates of sickness absences and early leaves form work than women; manufacturing workers had higher rates of sickness absences and early leaves form work than office workers. After confounding variables that had significant difference in univariate analysis on each symptom locations were adjusted, the odds ratios for sickness absence and early leaves divided by pain intensity were 4.361(neck), 4.140(shoulder), 3.151(arm/wrist), 3.085(leg/foot), and 2.731(waist), respectively; these differences were statistically significant. Conclusions: The rates of sickness absence and early leaves in each work-related musculoskeletal symptom locations were highest among workers with waist symptoms, and the intensity of pain was identified to have a considerable effect on the rates of sickness absences and early leaves. Based on these results, we think that there are needs to be early interventions on workers with waist symptoms.
