This study examines variation in suicide deaths by occupational skill level within the construction industry and changes in the rate of suicide over time.
Suicide deaths were extracted from a national coronial database and occupations were coded. Adjusted suicide rates over the period 2001 to 2010 were calculated and incidence-rate ratios (IRRs) used to compare the overall burden of suicide in the lowest skilled group (machine operators and labourers) against skilled tradespersons in the construction industry.
Those employed as labourers or machine operators had an adjusted rate of 18 per 100,000 persons (95%CI 14-22) and those employed in skilled trades had an adjusted rate of 13 per 100,000 (95%CI 11-15) over the period 2001 to 2010. Compared to skilled trades, the lower skilled group had significantly elevated suicide at several time points over the period 2001 to 2010. The most observable difference in IRRs were in the years 2002 and 2007.
Low-skilled workers in the construction industry had elevated rates of suicide compared to skilled trades workers.
These workers should be targeted by prevention efforts.
本研究调查了建筑业中按职业技能水平划分的自杀死亡差异以及自杀率随时间的变化。
从国家死因数据库中提取自杀死亡案例并对职业进行编码。计算了2001年至2010年期间的调整后自杀率，并使用发病率比（IRR）来比较建筑行业中技能水平最低组（机器操作员和体力劳动者）与技术工人的总体自杀负担。
在2001年至2010年期间，体力劳动者或机器操作员的调整后自杀率为每10万人中有18人（95%置信区间14 - 22），技术工人的调整后自杀率为每10万人中有13人（95%置信区间11 - 15）。与技术工人相比，技能水平较低的组在2001年至2010年期间的几个时间点自杀率显著升高。发病率比最明显的差异出现在2002年和2007年。
与技术工人相比，建筑业中的低技能工人自杀率较高。
预防工作应针对这些工人。
