Abstract
BACKGROUND Existing evidence suggests that some individuals from ethnic minority backgrounds are at increased risk of suicide compared to their majority ethnic counterparts, whereas others are at decreased risk. We aimed to estimate the absolute and relative risk of suicide in individuals from ethnic minority backgrounds globally. METHODS Databases (Medline, Embase, and PsycInfo) were searched for epidemiological studies between 01/01/2000 and 3/07/2020, which provided data on absolute and relative rates of suicide amongst ethnic minority groups. Studies reporting on clinical or specific populations were excluded. Pairs of reviewers independently screened titles, abstracts, and full texts. We used random effects meta-analysis to estimate overall, sex, location, migrant status, and ancestral origin, stratified pooled estimates for absolute and rate ratios. PROSPERO registration: CRD42020197940. FINDINGS A total of 128 studies were included with 6,026,103 suicide deaths in individuals from an ethnic minority background across 31 countries. Using data from 42 moderate-high quality studies, we estimated a pooled suicide rate of 12·1 per 100,000 (95% CIs 8·4-17·6) in people from ethnic minority backgrounds with a broad range of estimates (1·2-139·7 per 100,000). There was weak statistical evidence from 51 moderate-high quality studies that individuals from ethnic minority groups were more likely to die by suicide (RR 1·3 95% CIs 0·9-1·7) with again a broad range amongst studies (RR 0·2-18·5). In our sub-group analysis we only found evidence of elevated risk for indigenous populations (RR: 2·8 95% CIs 1·9-4·0; pooled rate: 23·2 per 100,000 95% CIs 14·7-36·6). There was very substantial heterogeneity (I2 > 98%) between studies for all pooled estimates. INTERPRETATION The homogeneous grouping of individuals from ethnic minority backgrounds is inappropriate. To support suicide prevention in marginalised groups, further exploration of important contextual differences in risk is required. It is possible that some ethnic minority groups (for example those from indigenous backgrounds) have higher rates of suicide than majority populations.

Abstract
BACKGROUND Suicide is the second leading cause of death among adolescents worldwide, and is a major driver of health inequity among Indigenous people in high-income countries. However, little is known about the burden of suicide among Indigenous populations in low- and middle-income nations, and no synthesis of the global data is currently available. Our objective was to examine the global incidence of suicide among Indigenous peoples and assess disparities through comparisons with non-Indigenous populations. METHODS We conducted a systematic review of suicide rates among Indigenous peoples worldwide and assessed disparities between Indigenous and non-Indigenous populations. We performed text word and Medical Subject Headings searches in PubMed, MEDLINE, Embase, Cumulative Index of Nursing and Allied Health (CINAHL), PsycINFO, Latin American and Caribbean Health Sciences Literature (LILACS), and Scientific Electronic Library Online (SciELO) for observational studies in any language, indexed from database inception until June 1, 2017. Eligible studies examined crude or standardized suicide rates in Indigenous populations at national, regional, or local levels, and examined rate ratios for comparisons to non-Indigenous populations. RESULTS The search identified 13,736 papers and we included 99. Eligible studies examined suicide rates among Indigenous peoples in 30 countries and territories, though the majority focused on populations in high-income nations. Results showed that suicide rates are elevated in many Indigenous populations worldwide, though rate variation is common, and suicide incidence ranges from 0 to 187.5 suicide deaths per 100,000 population. We found evidence of suicide rate parity between Indigenous and non-Indigenous populations in some contexts, while elsewhere rates were more than 20 times higher among Indigenous peoples. CONCLUSIONS This review showed that suicide rates in Indigenous populations vary globally, and that suicide rate disparities between Indigenous and non-Indigenous populations are substantial in some settings but not universal. Including Indigenous identifiers and disaggregating national suicide mortality data by geography and ethnicity will improve the quality and relevance of evidence that informs community, clinical, and public health practice in Indigenous suicide prevention.

Abstract
This study is the first comprehensive analysis to investigate the potential association between stock market fluctuations and attempted suicide events as measured by self-inflicted injuries treated in hospitalization. Using nationwide, 15-year population-based data from 1998 through 2012, we observe that the occurrences for the hospitalizations of attempted suicides are apparently predicted by stock price movements. A low stock price index, a daily fall in the stock index, and consecutive daily falls in the stock index have been shown to be associated with increased risk of hospitalization in patients with attempted suicide. More specifically, stock price index is found to be significant impact on attempted suicide in the 45-54 age groups of both genders, whilst daily change is significant for both genders in the 25-34 and 55-64 age groups and accumulated change is only significant in female aged 25-44 and above 65. On the basis of the results, relevant organizations should consider the suicidal factors that relate prime-working-age and near-retirement-age people to better carry out specific suicide prevention measures, and, meanwhile, encourage those people to pay less attention towards daily stock price movements.

Abstract
OBJECTIVE To analyze mortality rates and to describe the demographic and epidemiological characteristics of suicides recorded in the state of Amazonas. METHODS A descriptive and retrospective study has been carried out with emphasis on municipalities, which have shown, simultaneously, a high mortality rates and a high proportion of self-reported indigenous population, based on 2005 - 2009 data as provided by the Informatics Department of the Unified National Health System. RESULTS Among the general population of the state of Amazonas, the mortality rate, by suicide, of 4.2/100.000 inhabitants has been reported, similar to that of Manaus (4.6/100.000 inhabitants). In contrast, at Tabatinga (25.2/100.000 inhabitants), at São Gabriel da Cachoeira (27.6/100.000 inhabitants) and at Santa Isabel do Rio Negro (36.4/100.000 inhabitants), municipalities, where the proportion of self-reported indigenous population is high, besides the taxes being notably higher, it was observed that most of the suicides has occurred among men; among young men aged between 15 - 24 years; at home; by hanging; during "weekend" and among the indigenous population. DISCUSSION Our findings have unveiled that suicide comes forth as a serious public health issue in some municipalities in the state of Amazonas, further indicating that the event occurs within very specific contexts, and that the dimension and the magnitude of the problem can be even more serious among populations or in territories exclusively inhabited by indigenous people.

Abstract
This study examined the ethnic differences in stressors, risk, and protective factors among people who attempted suicide in Singapore. A retrospective chart review of 626 attempted suicide cases at a hospital in Singapore between 2004 and 2006 collected information on diagnosis according to DSM-IV-TR criteria. Chi-square tests was used to compare the sociodemographic characteristics, stressors, risk factors, and protective factors among Chinese, Malay, Indian, and other ethnic groups. Logistic regression was used to determine the odds ratios of having two or more stressors, risk factors, or protective factors for the four ethnic groups. Women were more likely than men to attempt suicide, although they also were more likely to have two or more suicide protective factors than men. In general, older people were more likely to have two or more suicide risk factors than the younger groups. Ethnic differences were found in history of psychiatric illnesses and unemployment among the risk factors, and for most of the protective factors, but none of the stressors. Indians were more likely to have two or more protective factors than were Chinese (OR of 7.74, 95% CI [1.04, 8.72]. Future suicide prevention programs should target young adults and strengthen the protective factors among different ethnic groups.

Abstract
BACKGROUND Suicide prevention is given a low priority in many Western Pacific countries due to competing health problems, stigma and poor understanding of its incidence and aetiology. Little is known about the epidemiology of suicide and suicidal behaviour in the Philippines and although its incidence is reported to be low, there is likely to be under-reporting because of its non-acceptance by the Catholic Church and the associated stigma to the family. This study aims to investigate trends in the incidence of suicide in the Philippines, assess possible underreporting and provide information on the methods used and the reasons for suicide. METHODS Data for suicide deaths occurring between 1974 and 2005 were obtained from Philippine Health Statistics. Age- and sex-specific trends were examined graphically. Underreporting was investigated by comparing trends in suicides, accidents and deaths of undetermined intent. To provide a fuller picture of suicide in the Philippines, a comprehensive search for published papers, theses and reports on the epidemiology of suicide in the Philippines was undertaken. RESULTS The incidence of suicide in males increased from 0.23 to 3.59 per 100,000 between 1984 and 2005. Similarly, rates rose from 0.12 to 1.09 per 100,000 in females. Amongst females, suicide rates were highest in 15-24 year olds, whilst in males rates were similar in all age groups throughout the study period. The most commonly used methods of suicide were hanging, shooting and organophosphate ingestion. In non-fatal attempts, the most common methods used were ingestion of drugs, specifically isoniazid and paracetamol, or organophosphate ingestion. Family and relationship problems were the most common precipitants. While rates were lower compared to other countries, there is suggestive evidence of underreporting and misclassification to undetermined injury. Recent increases may reflect either true increase or better reporting of suicides. CONCLUSIONS While suicide rates are low in the Philippines, increases in incidence and relatively high rates in adolescents and young adults point to the importance of focused suicide prevention programs. Improving data quality and better reporting of suicide deaths is likewise imperative to inform and evaluate prevention strategies.
