Abstract

Objectives: A number of studies on the trends of socioeconomic differences in suicide mortality have indicated that these inequality gaps have widened over time and highlight that certain occupations have more suicide risk than others. However suicide rates according to occupation based socioeconomic position have not been frequently studied in Korea. The purpose of this study is to report trends and inequality of suicide according to occupation based social class during 1993-2007 in Korea and to identify occupations with significantly high standardized mortality ratios (SMRs) and proportional mortality ratios (PMRs) for both men and women. Methods: Korean census records for the years 1995, 2000, and 2005 were linked with the cause of death records from Korean National Statistical Office (KNSO) for the periods 1993-1997, 1998-2003, and 2004-2007 respectively. This data was used to calculate age adjusted proportional mortality ratios (PMRs) and standardized mortality ratios (SMRs) for both men and women aged 25~54 years according to five occupation based socioeconomic positions. Results: Among men, the agricultural-fishery-forestry group had the greatest suicide rate (SMR: 341) with a high PMR (113) and the manual labor group showed the highest PMR (118), while the managersprofessional occupation group showed the lowest sPMR (78) and SMR (21). Among women, the agricultural- fishery group had the highest score in SMR (316) and PMR (130), and the technical-artificer group showed the lowest sPMR (71) and SMR (27). The inequality gaps in the suicide mortality rate according to occupation had widened during 1998-2002, but showed a recovery trend plot after 2003. Conclusions: Although the occupation based socioeconomic inequalities show a recovery trend after 2003, the excess inequality from suicide remains as high as it was prior to the 2002 year in some occupational groups. The results of the current study indicate that the manual and agricultural-fishery-forestry groups were high risk groups of suicide.

목적: 본 연구는 1993년 부터 2007년 까지의 직업군별 자살 사망률 추이를 비교하여, 타 직업군에 비해 높은 표준사망비와 비례사망비를 갖은 집단을 찾고자 하였다. 방법: 대한민국 통계청의 1993-1997, 1998-2003, 2004-2007년 기간의 전국민 사망자료를 각각 1995, 2000, 2005년의 대한민국의 전국민 센서스 자료와 짝을 이루게 구성하였다. 자살은 고의적 자의에 의한 상해가 원인이 되는 모든 사망으로 정하였고, 사망외인 코드 중 X60-X84 및 Y870에 해당하는 것으로 정의 하였다. 남녀별 5개의 직업군에 따라 연령보정비례사망비(sPMR)와 연령보정표준사망비(SMR)를 구하였다. 결과: 남성의 경우, 가장 높은 SMR은 농림어업군이었고 (SMR: 341, 95% CI: 331~346), 가장 높은 sPMR은 단순노무직이었다 (sPMR: 118, 95% CI:113~121). 가장 낮은 SMR과 sPMR은 관리-전문가 집단이었다 [SMR(95% CI): 21(19~1), sPMR(95% CI) :78 (75~80)], . 여성의 경우, 가장 높은 SMR과 sPMR이 농림어업군이었다 [SMR (95%CI): 316(296~327), sPMR(95% CI): 130(122~135)]. 가장 낮은 SMR과 sPMR은 기능-기술직이었다[SMR(95%CI): 27(23~30), sPMR (95% CI) :71(61~77)]. 전체적으로는, 1993년부터 2002년 까지 직업군별 자살의 차이는 증가 되었으나, 2003년 이후 점차 감소하였다. 결론: 본 연구는 남자 단순 노무직의 높은 자살을 나타냈고, 농림어업 군은 전체 직업군에 비해 매우 높은 자살수준을 보이다가 2003년 이후에는 급격하게 감소 하였으나 여전히 가장 높은 자살을 보이는 집단임이었다.
