목적: 뇌ㆍ심혈관질환은 주요한 사망원인이며 우리나라 산업재해 보상에 있어 중요 부분을 차지하고 있다. 따라서 한국산업안전보건공단은 2000년도부터 지역 산업보건 기관을 통해 많은 사업장에 뇌ㆍ심혈관질환 예방 프로그램을 지원해왔다. 본 연구는 이 프로그램이 근로자의 뇌ㆍ심혈관질환 발병위험도 개선에 미치는 단기영향을 평가하고자 수행되었다. 방법: 2007년도 집중관리 프로그램 대상자 중 전후 발병위험도 평가가 가능했던 5,902명(53.3%)을 대상으로 혈압, 콜레스테롤, 비만도 및 발병위험도를 전후 비교하였다. 발병위험도 평가는 KOSHA CODE H-11-2004 지침을 사용하였다. 결과: 평균 수축기 및 이완기 혈압이 4.9 ㎜Hg, 3.1 ㎜Hg 감소하였으며 총콜레스테롤과 비만도(BMI)는 각각 8.4 g/dL, 0.1 ㎏/㎡ 감소하였다. 흡연율은 6.0% 감소하였으며 규칙적인 운동 시행률은 23.1% 증가하였다. 전체적인 발병위험도 개선율은 49.1%였다. 결론: 국가 지원의 뇌ㆍ심혈관질환 예방 프로그램은 단기적으로 좋은 성과를 나타냈다. 향후 연구에서는 사업장 단위의 장기적인 영향과 비용-효과에 대한 분석이 이루어질 필요가 있다.
Objectives: Cardiovascular disease is the leading cause of death and a major source of workers’ compensation claims in Korea. Since 2000 the Korea Occupational Safety and Health Agency (KOSHA), working through local occupational health institutions, has supported cardiovascular disease prevention programs at a number of companies in Korea. The purpose of this study was to assess the short-term effects of this effort. Methods: A total of 11,077 workers at risk were enrolled in the workplace cardiovascular disease prevention program and 5,902 workers (53.3%) completed the 1-year course during 2007. The program consisted of a medical checkup and health counseling for the workers by occupational health nurses. The guidelines for this prevention program were adopted from KOSHA Code H-11-2004. To determine the program’s effectiveness, the workers’ risks for cardiovascular disease were assessed before and one year after completion of the program. Results: The intervention led to significant reductions in the mean systolic and diastolic blood pressures of 4.9 ㎜Hg and 3.1 ㎜Hg, respectively. Mean total cholesterol and BMI were also reduced significantly by 8.4 g/㎗ and 0.1 ㎏/㎡. The rate of smoking was decreased by 6.0% and the percentage of workers engaging in regular exercise was increased by 23.1%. Of the 3,530 workers with the low risk and above, the overall cardiovascular risk was improved in 1,734 (49.1%) of them. Conclusions: The cardiovascular disease prevention program supported by the Korea Occupational Safety and Health Agency reduces cardiovascular diseases risks among workers and may improve the health status of workers in Korea.
