Hanging is one of the most commonly used methods for suicide worldwide. In England and a number of other countries, its incidence has increased over the last 30 years. This review summarizes the published literature on suicide by hanging. The focus is on its epidemiology in England and on identifying potential means of prevention.
We searched Medline (1966-2003), Embase (1980-2003), CINAHL (1982-2003) and PsycINFO (1967-2003). As considerable research on suicides occurring in prisons and psychiatric hospitals in England and Wales has been carried out by the National Confidential Inquiry into Suicide and Homicide (Manchester) and the Prison Service's Safer Custody Group, we obtained additional information from these sources.
Only a small proportion (around 10%) of hanging suicides occur in the controlled environments of hospitals, prisons, and police custody; the remainder occur in the community. The most commonly used ligatures (rope, belts, flex) and ligature points (beams, banisters, hooks, door knobs, and trees) are widely available; thus prevention strategies focused around restriction of access to means of hanging are of limited value. Around 50% of hanging suicides are not fully suspended--ligature points below head level are commonly used. Case fatality following attempted suicide by hanging is around 70%; the majority (80-90%) of those who reach hospital alive survive.
Strategies to reduce suicide by hanging should focus on the prevention of suicide in controlled environments, the emergency management of 'near-hanging' and on the primary prevention of suicide in general. More research is required to better understand the recent rise in popularity of this method.
"The media’s reporting of suicide and its fictional portrayal on television are known to influence suicidal behavior, particularly the choice of method used [16-18]. Media guidelines for the sensational reporting of suicide are needed to reduce the portrayal of fictional suicides by lethal methods . Suicide by hanging might be influenced by altered public perception of its acceptability . "
[Show abstract][Hide abstract] ABSTRACT: Background
The lethality of the suicide method employed is a strong risk factor for the completion of suicide. We examined whether annual changes in the pattern of suicide methods is related to annual changes in suicide rates in South Korea, the United States (US), and Finland.
We analyzed annual data from 2000–2011 for South Korea and Finland, and 2000–2010 for the US in order to examine trends in the rates and methods of suicide. Data on suicide methods were obtained from the World Health Organization (WHO) mortality database.
Along with an annual rapid increase in suicide rates, the incidence of hanging increased steadily while suicide by self-poisoning steadily decreased in South Korea. In the US, along with an annual increase in suicide rates, the proportion of suicides committed by hanging increased while those committed with the use of firearms steadily decreased. In Finland, annual changes in the suicide rate and suicide method were not statistically significant during the study period.
Our present findings suggest that the increased use of specific lethal methods for suicide, namely hanging, is reflected in the increased suicide rates in the Korean and the US populations. The most effective approach for reducing overall suicide rates may be the implementation of population-based initiatives that reduce both the accessibility (e.g., access to firearms) and the social acceptability (e.g., effective and responsible regulations for reporting suicide) of lethal methods of suicide.

"This would also explain the high male-to-female suicide rate ratio, under the assumption that females more often use a “soft” method, such as poisoning . On the other hand, an increasing prevalence of hanging suicides has also been reported for England over three decades , and in Australia and New Zealand, especially among young males [28,29]. "
[Show abstract][Hide abstract] ABSTRACT: Background
Suicide rate trends for Poland, one of the most populous countries in Europe, are not well documented. Moreover, the quality of the official Polish suicide statistics is unknown and requires in-depth investigation.
Population and mortality data disaggregated by sex, age, manner, and cause were obtained from the Polish Central Statistics Office for the period 1970-2009. Suicides and deaths categorized as ‘undetermined injury intent,’ ‘unknown causes,’ and ‘unintentional poisonings’ were analyzed to estimate the reliability and sensitivity of suicide certification in Poland over three periods covered by ICD-8, ICD-9 and ICD-10, respectively. Time trends were assessed by the Spearman test for trend.
The official suicide rate increased by 51.3% in Poland between 1970 and 2009. There was an increasing excess suicide rate for males, culminating in a male-to-female ratio of 7:1. The dominant method, hanging, comprised 90% of all suicides by 2009. Factoring in deaths of undetermined intent only, estimated sensitivity of suicide certification was 77% overall, but lower for females than males. Not increasing linearly with age, the suicide rate peaked at ages 40-54 years.
The suicide rate is increasing in Poland, which calls for a national prevention initiative. Hangings are the predominant suicide method based on official registration. However, suicide among females appears grossly underestimated given their lower estimated sensitivity of suicide certification, greater use of “soft” suicide methods, and the very high 7:1 male-to-female rate ratio. Changes in the ICD classification system resulted in a temporary suicide data blackout in 1980-1982, and significant modifications of the death categories of senility and unknown causes, after 1997, suggest the need for data quality surveillance.

"Patients surviving an act of attempted hanging or attempted drowning showed a relatively low risk of non-fatal repetition. However, studies have shown their risk of fatal repeat acts to be relatively high , . "
[Show abstract][Hide abstract] ABSTRACT: Suicide is a significant public health issue with almost one million people dying by suicide each year worldwide. Deliberate self harm (DSH) is the single most important risk factor for suicide yet few countries have reliable data on DSH. We developed a national DSH registry in the Republic of Ireland to establish the incidence of hospital-treated DSH at national level and the spectrum and pattern of presentations with DSH and repetition.
Between 2003 and 2009, the Irish National Registry of Deliberate Self Harm collected data on DSH presentations to all 40 hospital emergency departments in the country. Data were collected by trained data registration officers using standard methods of case ascertainment and definition. The Registry recorded 75,119 DSH presentations involving 48,206 individuals. The total incidence rate fell from 209 (95% CI: 205-213) per 100,000 in 2003 to 184 (95% CI: 180-189) per 100,000 in 2006 and increased again to 209 (95% CI: 204-213) per 100,000 in 2009. The most notable annual changes were successive 10% increases in the male rate in 2008 and 2009. There was significant variation by age with peak rates in women in the 15-19 year age group (620 (95% CI: 605-636) per 100,000), and in men in the 20-24 age group (427 (95% CI: 416-439) per 100,000). Repetition rates varied significantly by age, method of self harm and number of previous episodes.
Population-based data on hospital-treated DSH represent an important index of the burden of mental illness and suicide risk in the community. The increased DSH rate in Irish men in 2008 and 2009 coincided with the advent of the economic recession in Ireland. The findings underline the need for developing effective interventions to reduce DSH repetition rates as a key priority for health systems.
