Abstract

This cross-sectional study was investigated musculoskeletal discomfort symptoms and related factors on some middle high school teachers. Self-questionnaire of KOSHA CODE H-30-2003 was done with 250 teachers from 1st to 15th October, 2010, the data from 231 teachers (68 male, 163 female) was statistically analyzed to search the factors related to musculoskeletal discomfort symptoms. According to NIOSH rate of musculoskeletal discomfort symptoms by body parts was 36.8%. Musculoskeletal discomfort symptoms related to age, school types, subjective health status, housekeeping time, VDT work time and regular rest. After adjusting for related variables, odds ratio (OR) of musculoskeletal discomfort symptoms was correlation significantly to subjective health status unhealthy (OR 11.75, 95% Confidence Interval, CI, 3.56-378.78). In addition, ORs (95% CI) of age (40-49) and housekeeping time (${\geq}3$) were 4.63 (1.82-26.18) and 4.33 (1.97-19.34). Analysis of the factors influencing the musculoskeletal discomfort symptoms vary in different parts of the body. The most discomfort symptoms by parts was neck (26.0%) and shoulder (30.0%). In the neck region was related to subjective health status and regular rest. In the shoulder and waist region was subjective health status and sex. Age was wrist/finger, leg/foot was related to subjective health status, sex and VDT work time. Age, school types, subjective health status, housekeeping time, VDT work time and regular rest related to musculoskeletal discomfort symptoms and the most discomfort symptoms by parts was neck and shoulder.

중 고등학교 교사의 근골격계 불편증상과 관련 요인을 알아보기 위해 2010년 10월 1일부터 10월 15일까지 250명의 교사들을 대상으로 근골격계 불편증상 설문조사를 실시하고, 231명(남자 68명, 여자 163명)의 결과를 신체 각 부위별로 통계분석 하였다. 근골격계 불편증상의 관련요인으로 특히 주관적 건강상태가 높은 연관성을 보였고(OR 11.75, 95% CI, 3.56-38.78), 그 외 근무학교유형, 40세 이상, 2시간 이상의 가사노동시간, 8시간 이상의 VDT작업시간, 휴식여부가 유의한 상관성이 있는 요인들로 분석되었다. NIOSH 기준에 의한 근골격계 불편증상 호소율은 36.8%였고, 각 부위별 불편증상 호소부위와 빈도는 목 60명(26.0%), 어깨 70명(30.0%), 팔/팔꿈치 16명(6.9%), 손/손가락 31명(13.4%), 허리 35명(15.2%), 다리/발 17명(7.4%)으로 목과 어깨의 발생빈도가 높았다. 목 부위는 주관적 건강상태와 휴식유무, 어깨부위는 주관적 건강상태와 성별, 손/손가락 부위는 연령, 허리부위는 주관적 건강상태와 연령, 다리부위는 주관적 건강상태와 연령, VDT작업시간이 관련성 있는 요인들로 분석되었다. 사무직근로자에서 근골격계 질환은 간단한 스트레칭만으로도 예방 가능하다. 신체 각 부위별로 간단하고 적절한 운동을 통해 자신의 건강상태를 유지하고 올바른 작업 자세와 작업요건을 갖추고 작업시간 중간에 충분한 휴식시간을 가짐으로써 직무로 인한 근골격계의 과도한 긴장과 불편감 발생을 낮추기 위한 스스로의 노력이 필요하다.
