To investigate whether suicide risk among agricultural workers is higher in regions with heavier pesticide use and/or presence of tobacco farming.
Suicide mortality data were gathered from residents of the Brazilian state of Alagoas. Agricultural census data were used to arrange and classify Alagoas cities into distribution groups on the basis of variables concerning pesticide use and/or tobacco farming. Mortality odds ratio calculations were then used to compare suicide risk among agricultural and nonagricultural workers in different groups.
Suicide risk was higher among agricultural workers than among nonagricultural workers, elevated in regions that used more pesticides, and greatest in regions that produced more tobacco.
This is one of the first studies of its kind to suggest that combined effects of pesticide and tobacco exposure may be linked to higher suicide risk among agricultural workers.
探究在农药使用量较大和/或存在烟草种植的地区，农业工人的自杀风险是否更高。
从巴西阿拉戈斯州的居民中收集自杀死亡率数据。利用农业普查数据，根据农药使用和/或烟草种植的相关变量，对阿拉戈斯州的城市进行排列和分类，将其分为不同的分布组。然后使用死亡率比值比计算来比较不同组中农业和非农业工人的自杀风险。
与非农业工人相比，农业工人的自杀风险更高，在使用更多农药的地区风险升高，在生产更多烟草的地区风险最高。
这是此类研究中的首例，表明农药和烟草暴露的综合效应可能与农业工人的更高自杀风险有关。
