Methods Poisoning A 2006 study conducted by Ghoreyshi and Mousavi Nasab, showed that 55.8% of the population of 3,477 chose drug overdose as the most preferred method with a median of 55.8% of the total population. In a meta-analysis study on other studies done until April 2012, Bidel and others found out that from all methods of poisoning, drug overdose with 75% and other poisons (including agricultural and domestic pesticides) with 13% had the most prevalence among suicides. According to this study, provinces of Golestan (90%), Markazi (89%), Razavi Khorasan (88%), and Hormozgan (88%) respectively, ranked the highest in suicide with drug overdose, and provinces of Ilam (25%), Bushehr (21%), and East Azerbaijan (20%) respectively, ranked the highest in suicide with other types of poisons. According to Bidel and others, the reason behind Ilam's high incidences of suicide with agricultural pesticides is because such substances are easily accessible in this province. Self-immolation According to a 2001 report by the medical jurisprudence organization of Iran, self-immolation has been the most chosen method of suicide among women with 69.29% prevalence. This report also states that the highest rate of self-immolation as a method of suicide among men was from Yazd Province with 47% prevalence and the highest suicide rate with this method for women was recorded in Bushehr province with 94.4% prevalence. In a meta-analysis study consisted of 19 studies with a population of 22,498 suicide cases until 2012, Nazarzade and others have concluded that generally speaking, from all physical methods of suicide, self-immolation, with a prevalence of 13%, is the most chosen method of suicide in Iran. They also found that the provinces of Kohgiluyeh and Boyer-Ahmad (48%), Ilam (28%), and South Khorasan (10%), respectively, ranked the highest rates for self-immolation as a method of killing oneself. According to Nazarzade and others, although suicide by this method in Iran occurs less than in other countries like India (40%), Sri Lanka (24%), and Egypt (17%), the prevalence of this method in Iran is more than some African countries like Zimbabwe (11%) and South Africa and also some European countries like Germany. Their report states that in general and except for poisoning, Iranian men and women tend to use violent methods like self-immolation, hanging, and shooting with firearms for their suicide. The prevalence of these types of methods is higher in western and south-eastern provinces of the
