This study aims to identify the risk factors of suicidal ideation (SI) in a large sample of Chinese adults in the labour force. A total of 4136 eligible participants in the labour force were recruited from the routine health check-up cohort. Univariate and multivariate logistic regression were used to identify the factors associated with 12-month and lifetime SI. 175 (4.2%) subjects reported SI in the past twelve months, and 223 (5.4%) reported SI during their lifetime. The results showed that being divorced or widowed, religious belief, personal history of chronic disease and mental illness, family history of mental illness and suicide, and self-assessed childhood happiness were associated with both 12-month and lifetime SI. Additional associations were found between 12-month SI and the following factors: working overtime frequently, low monthly income, and having bachelor's degree. Moreover, being single is a risk factor of lifetime SI while not significant for 12-month SI. The present study identified several risk factors of 12-month and lifetime SI, which could potentially help develop targeted interventions for high-risk suicidal Chinese adults in the labour force.
本研究旨在确定中国成年劳动力大样本中自杀意念（SI）的风险因素。从常规健康检查队列中招募了总共4136名符合条件的劳动力参与者。采用单因素和多因素逻辑回归来确定与12个月和终生自杀意念相关的因素。175名（4.2%）受试者报告在过去十二个月中有自杀意念，223名（5.4%）报告终生有自杀意念。结果表明，离婚或丧偶、宗教信仰、慢性病和精神疾病个人史、精神疾病和自杀家族史以及自我评估的童年幸福感与12个月和终生自杀意念均相关。在12个月自杀意念与以下因素之间还发现了其他关联：经常加班、月收入低以及拥有本科学历。此外，单身是终生自杀意念的一个风险因素，而对12个月自杀意念则不显著。本研究确定了12个月和终生自杀意念的若干风险因素，这可能有助于为中国成年劳动力中高风险自杀人群制定有针对性的干预措施。
