Abstract

치과위생사의 주요 건강문제인 근골격계 장애를 조사하고, 근무환경 요인과 스트레스 및 근골격계 장애의 관련성을 파악하기 위해 광주지역 치과위생사 483명을 편의 추출하여 자기기입식 설문조사를 시행하고 빈도분석, 교차분석, t-검정, 다중 로지스틱 회귀분석을 실시하여 분석한 결과는 다음과 같다. 연구대상자의 심한 통증을 호소하는 정도인 근골격계 장애는 29.8%였다. 근무환경요인과 스트레스 및 근골격계 장애의 관련성을 파악한 결과, 근무환경 요인에서 휴식시간 빈도였으며, 그 외 스트레스 요인 등이었다. 근무환경 요인에서 휴식시간 빈도가 없음으로 응답한 군에 비해 2회라고 응답한 군의 OR은 0.29 (95% CI, 0.11~0.73)로 근골격계 장애가 감소하여 유의한 차이를 보였으나, 휴식시간 빈도가 1회와 3회 이상에서는 유의한 차이가 없었다. 스트레스의 근골격계 장애 OR은 0.44 (95% CI, 0.27~0.70)로 음의 상관관계를 보였다. 이것은 휴식시간 빈도가 적당할수록(2회일 때) 근골격계 장애가 낮음을 의미하며, 근골격계 장애가 있는 경우 스트레스가 낮게 나타났다. The purpose of this study is to examine musculoskeletal disorders and grasp the relationship between working environment factors and stress and musculoskeletal disorders in dental hygienists. The self-administered questionnaire survey was conducted with 483 dental hygienists working in Gwangju who were selected by convenience sampling. Frequency analysis, crosstab analysis, t-test, and multiple logistic regression analysis were made. Subjects' musculoskeletal disorders that complain of severe pains were 29.8%. The relationship between working environment factors and stress and musculoskeletal disorders were examined. As a result, work break frequency of working environment factors and stress were found to influence musculoskeletal disorders. For working environment factors, the odds ratio of musculoskeletal disorders of the two breaks group was 0.29 (95% confidence interval [CI], 0.11~0.73), compared with the no break group, indicating less musculoskeletal disorders. However, no significant difference was found in one break and more than three breaks groups. The odds ratio of musculoskeletal disorders of stress was 0.44 (95% CI, 0.27~0.70), indicating negative correlation. As break frequency was moderate (two breaks), musculoskeletal disorders became decreased. Stress showed negative correlation with musculoskeletal disorders.
