Suicide is derived from the latin word for self murder.
US : > 30.000 persons die by suicide each year ; attempted suicides : 650.000
Risk factors :
sex : men commit suicide > 4 X women; women attempt suicide > 4X men
age ; men : suicides peak: >45 years, women > 55 years
marital status : marriage reinforced by children seems to lessen the risk of suicide significantly.
a person’s social status risk of suicide
Fall in social status risk of suicide
Greatest risk of suicide : professionals, particularly physicians.
Among physicians, psychiatrists are considered to be at greatest risk, followed by ophthalmologist & anesthesiologist, but the trend is toward an equalization among all specialties.
Special at risk populations : musicians, dentists, law enforcement officers, lawyer & insurance agents. Unemployed >> employed persons,
Men : fire arms, hanging, jumping from high places.
Women : overdose of psychoactive substances or a poison
Globally, the most common method of suicide is hanging
Emile Durkheim ( French sociologist )
Durkheim divided suicides into 3 social categories : egoistic, altruistic & anomic.
Egoistic suicide not strongly integrated into any social group. Lack of family integration explains why unmarried persons suicide >>married; & why couples with children are the best protected group. Rural communities…
…>> social integration than urban areas; & thus less suicide.
Altruistic suicide applies to those prone to suicide stemming from their excessive integration into a group, with suicide being the outgrowth of the integration, e.g : Japanese soldier who sacrifices his life in battle.
Anomic suicide applies to persons whose integration into society is disturbed so that they can’t follow customary norms of behavior. Anomie explain why a drastic change in economic situation makes persons >> vulnerable than before their change in fortune, anomie: social instability & general breakdown society standards & values

Biological Factors : serotonin metabolite 5-hydroxyindoleacetic acid (5-HIAA) in CSF
Genetic Factors : Margaux Hemingway ‘s 1997 suicide was the 5 th suicide among 4 generations of Ernest Hemingway’s family.
Molecular Genetic Studies: Polymorphism in Tryptophan hydroxylase (TPH) : enzyme involved in biosynthesis serotonin 2 alleles : U & L
L allele: associated with repetitive suicidal behavior.
Parasuicide : patients who injure themselves by self-mutilation (e.g. cutting the skin) but who usually do not wish to die.
4 % of all patients in psychiatric hospitals have cut themselves; female:male ratio: 3 :1
Incidence of self- injury in psychiatric patients > 50 x general population
