This study investigated whether the association between workplace conditions and the risk of all-cause and cardiovascular mortality and acute myocardial infarction differed by socioeconomic status.
Prospective data were used to examine these associations in 2297 Finnish men, with adjustment for prevalent diseases and biological, behavioral, and psychosocial covariates, and stratified by employment status and workplace social support.
Elevated age-adjusted relative hazards for all-cause mortality were found for men who reported high demands, low resources, and low income; high demands, high resources, and low income; and low demands, high resources, and low income. Similar patterns were found for cardiovascular mortality. In contrast, elevated age-adjusted relative hazards for acute myocardial infarction were observed only in men who reported high demands, low resources, and low income. These results did not differ by level of workplace social support or employment status.
The negative effects of workplace conditions on mortality and of myocardial infarction risk depended on income level and were largely mediated by known risk factors.
本研究调查了工作场所条件与全因死亡率、心血管死亡率及急性心肌梗死风险之间的关联是否因社会经济地位而异。
采用前瞻性数据对2297名芬兰男性的这些关联进行研究，对常见疾病以及生物学、行为和心理社会协变量进行了校正，并按就业状况和工作场所社会支持进行分层。
报告高要求、低资源和低收入；高要求、高资源和低收入；以及低要求、高资源和低收入的男性，其全因死亡率的年龄调整相对风险升高。心血管死亡率也发现了类似模式。相比之下，仅在报告高要求、低资源和低收入的男性中观察到急性心肌梗死的年龄调整相对风险升高。这些结果在工作场所社会支持水平或就业状况方面并无差异。
工作场所条件对死亡率和心肌梗死风险的负面影响取决于收入水平，并且在很大程度上由已知风险因素介导。
