Suicide rates among industrial groups were examined systematically using death certificate data from 1984 through 1989 in Alabama. Poisson log-linear modelling was used to estimate the rate ratios (RR) of industries compared to a referent and to adjust for confounding. Marked differences in suicide rates were found among industrial groups. The rates ranged from 5.31 to 62.36 per 100,000 population per year. People employed in public administration had the lowest rate. In comparison with public administration, the construction industry had the highest risk (adjusted RR = 11.8, 95% confidence interval (CI): 9.6-14.6). Employees of the mining industry experienced a similarly high risk (adjusted RR = 11.5, 95% CI: 8.2-16.3). Persons employed in farming, agriculture services, forestry, and fisheries, manufacturing, and transportation, communications, and other public utilities industries had intermediate risks. Smaller elevations of suicide rates compared to public administration were observed in the wholesale trade, retail trade, finance, insurance, and real estate, and services industries. The differences of suicide rates may be related to sociodemographic differences, self-selection for occupation, ease of access to lethal agents, or job stress.
利用阿拉巴马州1984年至1989年的死亡证明数据，对各行业群体的自杀率进行了系统研究。采用泊松对数线性模型来估计各行业与参照行业相比的率比（RR），并对混杂因素进行调整。研究发现各行业群体的自杀率存在显著差异。自杀率范围为每年每10万人口5.31至62.36例。公共管理部门的从业人员自杀率最低。与公共管理部门相比，建筑业的风险最高（调整后的RR = 11.8，95%置信区间（CI）：9.6 - 14.6）。采矿业的员工也面临类似的高风险（调整后的RR = 11.5，95% CI：8.2 - 16.3）。从事农业、农业服务、林业、渔业、制造业以及交通运输、通信和其他公用事业行业的人员面临中等风险。与公共管理部门相比，批发贸易、零售贸易、金融、保险和房地产以及服务业的自杀率略有升高。自杀率的差异可能与社会人口统计学差异、职业的自我选择、获取致死手段的难易程度或工作压力有关。
