Abstract have shown that the proportion of the population from nonwhite minority ethnic groups increased by 53% between 1991 and 2001, from 3 million to 4.6 million (or 7.9% of the total UK population). Approximately 35% of these immigrants belong to families of South Asian origin (Pakistan, India, and Bangladesh).1 This population is diverse in terms of age, education, occupation, and religious affiliation.

Since earliest recorded times people have attempted and completed suicide. The reasons and methods of suicide show variations across cultures. UK censuses carried out in 2001 revealed that the proportion of the UK population belonging to a non-white minority ethnic group increased, from 3 million to 4.6 million (or 7.9% of the total UK population). This population is diverse in terms of age, education and occupation. Based on available research over the years, an increase in number of suicides, particularly among Asians, has been reported. Social and cultural factors, mainly social integration and religion, play an important part in determining varying rates of suicide. Cross-sectional surveys suggest that factors to do with people’s attempts to commit suicide relate to both their home culture and the culture of the host country e ‘acculturation stress’. This may increase the likelihood of attempted suicide. Committing suicide by burning, poisoning and using pesticides are common in female migrants. Despite a comparatively high prevalence of depression, self-harm and suicide, there is a lack of treatment evidence for these ethnic minority groups, which results in a delay in help-seeking and in accessibility and awareness of pathways of care. Issues that are related to the person’s sociocultural background should be examined in particular while assessing for suicide risk. Additionally, there is a need to look at risk and protective factors in these ethnic groups, which can guide us in developing culturally sensitive interventions.

Historical and religious background Since earliest recorded times, humans have attempted and completed suicide, and the reasons and methods of suicide show variation across cultures. For example, ancient Hindu texts allowed individuals to kill themselves: ‘Sati’ (a Hindu widow throwing herself on to her husband’s funeral pile) has existed as an act of ritual suicide amongst Hindus for several centuries. Although now unlawful, it still occurs occasionally in India. Cultural factors and gender role expectations of being a good wife play a significant role in the act and its consequences. Other religions, particularly Islam, forbid suicide, and this is the main reason why suicide is unlawful and still remains a socially unacceptable act, especially for Muslims.

Suicide rates among the immigrant population in the UK were first published in the national analysis of immigrant mortality in the 1970s. Since then, a consistent increase in the number of suicides among the Asian immigrant population has been reported.2 A series of publications by Raleigh and Balarajan on rates of suicide in ethnic minorities in the UK showed that standardized mortality rates for suicide were three times higher than national rates for young Indian females (aged 15e34 years), with an excess mortality rate of 43%. Rates were lower for Indian males and elderly Indian women than for the corresponding members of the white population.3,4 These mortality rates appear to be rising. Recent analysis of suicide mortality data (1999e2003) shows that the age-specific suicide rate in young women of South Asian origin was lower than that for women in England and Wales. The suicide rate in those over 65 years was double that of England and Wales.5 Immigrants from the Indian subcontinent settled in non-Western countries such as Malaysia and Fiji have rates of suicide up to six times greater than those of the native populations.2

Ethnic Minority Psychiatric Illness Rates in the Community Survey. Low rates were reported by men (with the exception of Irish males) and higher rates amongst females of Pakistani and Indian origin.6 Other studies of rates of self-harm from hospitalbased samples follow a similar pattern, with higher rates in South Asian females compared with white females and South Asian males. However, there do not appear to be differences in the rates of self-harm in South Asian and white adolescent females.7,8

Despite the fact that the earlier generations of immigrants strived to adhere to their own cultural systems, with the passage of time later generations are becoming increasingly westernized in their approach to life and social values. The rate of acculturation is much higher in later generations of immigrants who have been born and brought up in the West. Effect of religion Amongst ethnic minority groups, Muslims have lower rates of suicide compared with practising Hindus or Sikhs.11 This trend is evident not only in the UK but also in other countries, such as Fiji and South Africa, where they have settled as minorities.2

Comparison of associated factors Cultural issues Social and cultural factors, mainly social integration and religion, play an important part in determining varying rates of suicide in different parts of the world (Figure 1). Cross-sectional surveys in North America suggest that factors associated with people’s suicide attempts relate both to their home culture and to the culture of their host country.9,10 Over time, immigrants tend to experience ‘acculturative stress’ when trying to assimilate with the host culture. Rates of acculturative stress experienced vary with individuals, and first- and second-generation family members may acculturate at a different pace. This often leads to conflicts within the family and may increase the likelihood of attempted suicide.9,10 Most immigrant communities have retained their traditions and cultural identity even after years of living abroad. Migrants can experience emotional and physical stress, in addition to having to deal with a new culture, language, and social norms. Traditionally, an extended family is the structure of a subcontinent family, with multiple generations living together. The male is the head, breadwinner, and decision-maker of the family. The elderly are respected and honoured, and preference is given to male children. Arranged marriages are commonplace. Girls are very well protected and are expected to be virgins at the time of marriage e the family and community will reject an unmarried pregnant girl. Marriage has to be respected as an institution and personal sacrifices are expected, particularly from women, to keep a marriage intact in spite of mounting marital conflicts.

Social class differences Based on coroners’ verdicts, the proportion of suicides amongst professionals and managerial people from the Indian subcontinent is higher than among those of lower socio-economic status. Doctors and dentists, in particular, are over-represented.3,4 Culture-specific precipitating factors Young adolescents, particularly girls, become caught between two cultures and develop two identities: an identity for home and another identity for school. They have disciplinary arguments with parents around cultural issues, such as having a relationship with a white person, opposition to arranged marriages, expectation of entering higher education, and eventually planning to take up employment. This asynchronous acculturation leads to interpersonal conflicts within the immediate family and is a source of psychological distress. South Asian adolescents also tend to have more problems with siblings compared with their white counterparts.7 Married women commit suicide mainly because of problems in their relationships with in-laws, punctuated by repeated insults, taunts, and marital violence. Other factors can include their inability to bear children, particularly male children. These factors are cited as reasons for the higher rates of suicide amongst South Asian female immigrants compared with females from white or other ethnic minority populations.

Ethnic density Ethnic density refers to the proportion of either a specific or all groups of ethnic minorities in a particular geographical area.12 In areas of lower ethnic density, rates of self-harm rise with increasing ethnic density. After a peak (when ethnic density is around a standard deviation below the study area mean), selfharm then decreases with a further increase in the density.13

Differences in methods of suicide Suicide by hanging has been reported as the most common method employed by immigrants to the UK from the Indian subcontinent. Suicide by burning, and poisoning using pesticides, are common among female migrants. South Asian females are over-represented amongst cases of self-inflicted burns in all such cases reported in UK.2

common cause of suicide in Western countries. The EMPIRIC study found that subjects who had attempted suicide in the past had higher distress scores.14 Some 6% of all suicides committed within 12 months of contact with psychiatric services were by people from ethnic minority populations. The most common method of suicide was hanging; violent methods were more common than in white patient suicides. Schizophrenia was the most common diagnosis. Patients from ethnic minorities were more likely to have been unemployed than white patients and to have had a history of violence and recent non-compliance. In around half of the cases of suicide, this was the first episode of self-harm.15 Depression has been reported to be less common in the selfharming South Asian population. Impulsive acts of self-harm due to interpersonal stress are more frequent, especially in the adolescent age group.7

Migration (if indicated) and associated stressors and social support Cultural identity and cultural alienation Gender-role expectations Type of family network (e.g. extended, nuclear) Social support and confidantes Cultural idioms of distress and expectations Any previous racial life events Note that suicidal motivation may be interpreted by the attempter in terms of cultural expectations of behaviour

Delay in seeking help Box 1

Evidence suggests that South Asian females seek help at the point of desperation very late in the course of their problems.16 This phenomenon can be explained by the cultural factors discussed above, whereby seeking help for mental distress is considered stigmatizing and socially unacceptable. South Asian females are half as likely to obtain medical attention following attempted suicide compared with white British and Irish patients. The participants in this study16 also agreed that an inability to speak English increased their sense of isolation, and that the absence of a confiding relationship was also a precipitating factor for their behaviour. The women used self-harm as a response to social isolation and as a logical behaviour to reduce distress and ask for help.16

groups, the therapeutic processes and delivery mechanisms for the interventions need to be tailored to make them more appropriate and acceptable. Specific preventive actions must take account of the ethnic variations of clinical indices of risk and include more effective treatment of psychosis.18 Bhugra and Hicks piloted an educational pamphlet about depression and suicidality.19 After reading the pamphlet, significantly more women assessed themselves as willing to confide in their clinicians, friends, and spouses if they felt depressed or suicidal, rather than not telling anyone. In addition, more women reported that they felt antidepressants were helpful for depression after they had read the pamphlet. These changes remained 4e6 weeks later.19

Pathways to care Participants in a qualitative study16 stated that they would be unable to access mainstream services because they would not be able to trust the providers of these services. The fear of the community ‘grapevine’ even prevents these women from seeking help from their general practitioners (GPs). They worried that ‘the GP might be your family GP and may tell your parents’ or ‘it would go down on your record’. The women also feared that the general practice staff or the GP might be part of the local community. As stated above, these women already have a feeling of isolation, and this is increased by the barriers to accessing GPs and other service providers.16 An audit of the management of self-harm in accident and emergency departments revealed that South Asian women were managed differently, even though there were no differences in their clinical presentation and risk assessment women compared with white females. Interpersonal family conflicts were the main precipitating factors, yet these women were sent back home under the care of their GP, whereas white women were referred more frequently to mental health services.17

Assessment General principles of suicide risk assessment are applicable, although issues specific to the person’s sociocultural background should also be investigated (Box 1). Language must never be allowed to create a barrier to assessment, and properly trained interpreters should be involved. Training healthcare staff in using interpreters will

increase the quality of such three-way communication. Owing to possible sensitivities, the use of family members as interpreters should be avoided.

Prevention of suicide in South Asian immigrants The key to developing effective prevention strategies is to employ them at the right time and to make them culturally sensitive. With no differences in suicide rates in adolescents and then a sudden rise in the rates among young women, this offers us a chance to focus on this window of opportunity. Further research into risk and protective factors at this level can guide us in developing our interventions (Box 2). A
