Although household air pollution (HAP) is associated with an increased risk of mental disorders, evidence remains scarce for the relationship between HAP and suicidal ideation. A total of 21,381 qualified participants were enrolled on the Henan Rural Cohort Study. HAP information including cooking fuel type, cooking duration and kitchen ventilation was collected by questionnaires. Suicidal ideation was evaluated by item nine of the Patient Health Questionnaire-9 (PHQ-9). Independent and combined associations of cooking fuel type and cooking duration with suicidal ideation were explored by logistic regression models. Analyses were conducted in different kitchen ventilation groups to detect the potential effect modification. The adjusted odds ratio (OR) and 95% confidence interval (95% CI) of solid fuel users versus clean fuel users for suicidal ideation was 1.37 (1.16, 1.62), and the risk of suicidal ideation increased by 15% (95% CI: 5%, 26%) for each additional hour of the cooking duration. Participants cooking with solid fuel for long durations were related to the highest risk of suicidal ideation (OR (95% CI): 1.51 (1.22, 1.87)). However, all these associations were not observed in those cooking with mechanical ventilation. Mechanical ventilation ameliorated relationships between solid fuel use and long-duration cooking with suicidal ideation.
虽然家庭空气污染（HAP）与精神障碍风险增加有关，但关于HAP与自杀意念之间关系的证据仍然很少。共有21381名合格参与者纳入了河南农村队列研究。通过问卷调查收集包括烹饪燃料类型、烹饪时长和厨房通风情况在内的家庭空气污染信息。采用患者健康问卷-9（PHQ-9）的第9项评估自杀意念。通过逻辑回归模型探讨烹饪燃料类型和烹饪时长与自杀意念的独立及联合关联。在不同厨房通风组中进行分析以检测潜在的效应修正。固体燃料使用者与清洁燃料使用者相比，自杀意念的校正比值比（OR）和95%置信区间（95%CI）为1.37（1.16，1.62），烹饪时长每增加1小时，自杀意念风险增加15%（95%CI：5%，26%）。长时间使用固体燃料烹饪的参与者自杀意念风险最高（OR（95%CI）：1.51（1.22，1.87））。然而，在使用机械通风烹饪的人群中未观察到所有这些关联。机械通风改善了使用固体燃料和长时间烹饪与自杀意念之间的关系。
