Objective

To assess prevalence of suicidal ideation and suicide attempt among South Brazilian tobacco growers and to analyze the associated factors related to the suicidal ideation.

Methods

A cross-sectional study was conducted in 2011 with a random sample of 2469 tobacco growers in São Lourenço do Sul/RS. Suicidal ideation was characterized by the question “Has the thought of ending your life been on your mind?”. Suicide attempt was assessed by the question “Have you ever tried to kill yourself?”. Investigation of factors associated with suicidal ideation was done by means of Poisson regression.

Results

Prevalence of suicidal ideation and suicide attempt was 2.5 % and 1.2 % respectively. In the adjusted analysis, suicidal ideation was associated with being female, older age, moderate participation in religious activities and difficulty in paying debts. Those who worked in activities that required inadequate postures (hunched over or other forced positions), as well as farmers who performed 6–9 pesticide-related tasks demonstrated greater risk of suicidal ideation. Regarding health conditions, medical diagnosis of asthma, chronic low back pain, number of lifetime green tobacco sickness episodes and lifetime pesticide poisoning were positively associated with suicidal ideation.

Conclusion

Suicidal thoughts and attempts are relevant mental health problems among tobacco growers. Reducing pesticide use, as well as exposure to nicotine and improving socio-economic conditions, can reduce suicidal ideation and improve the mental health of exposed workers.

巴西南部烟草种植者的自杀倾向

 客观的

评估南巴西烟草种植者自杀意念和自杀未遂的患病率，并分析与自杀意念相关的相关因素。

 方法

2011 年对南圣洛伦索/RS 的 2469 名烟草种植者进行了一项横断面研究。自杀意念的特点是“你的脑海中有结束生命的想法吗？”。自杀企图通过“您是否曾尝试过自杀？”这一问题进行评估。通过泊松回归研究与自杀意念相关的因素。

 结果

自杀意念和自杀企图的发生率分别为 2.5% 和 1.2%。在调整后的分析中，自杀意念与女性、年龄较大、适度参与宗教活动和偿还债务困难有关。那些从事需要不当姿势（弯腰或其他强迫姿势）的活动的人，以及执行 6-9 项与农药相关的任务的农民表现出更大的自杀意念风险。在健康状况方面，哮喘的医学诊断、慢性腰痛、终生绿色烟草病发作次数和终生农药中毒与自杀意念呈正相关。

 结论

自杀念头和企图是烟农的相关心理健康问题。减少农药的使用以及接触尼古丁并改善社会经济条件，可以减少自杀意念并改善接触尼古丁的工人的心理健康。
