ViolHelp: results of a pilot study to identify potential warning signs and risk factors for self- and hetero-directed violence in the calls received by the Helplines of the Italian National Institute of Health.

BACKGROUND: Self- and hetero-directed violence (SHDV) is a serious public health problem and a complex phenomenon, influenced by individual and environmental factors. SHDV may occur particularly in moments of personal, economic and/or social crisis. During the COVID-19 pandemic, the ISS-Helplines operators have perceived an increase in psychological distress and self-isolation among callers. The ViolHelp project aimed at identifying potential warning signs and risk factors of SHDV emerging in the activity of the ISS-Helplines (Istituto Superiore di Sanità, ISS, Italian National Institute of Health). MATERIALS AND METHODS: A dashboard collecting warning signs and risk factors of SHDV was developed to be used during the ISS-Helplines activity. RESULTS: In one year of data collection, 135 calls were compiled. In 106 calls, callers referred experienced violence: 72 self-directed violence (SDV), 20 hetero-directed violence (HDV), 14 both. The most frequent warning signs and risk factors for SDV were desire to die (68.6%), previous suicide attempts (31.4%) and threat of self-harm (25.6%); for HDV were depressed mood (32.4%), diagnosis of pathology and/or psychiatric disorders, desire to die, use of psychotropic drugs, and alcohol abuse (29.4%). CONCLUSIONS: The results of this pilot project show the importance of being able to read the warning signs and to create a network that can improve information, prevention and support activities for people at risk of violence and their families.

Suicide After Partner's Death in the Elderly Population: Results From a Nationwide Cohort Study in Italy.

OBJECTIVE: This study aims to investigate the effect of partner loss on suicide mortality for surviving partners in the elderly Italian population and to explore differences according to sex and time elapsed since the loss. DESIGN: This was a historical cohort study. SETTING: All Italian residents registered by the 15th Italian Population Census (9 October 2011) were linked to emigration records and death certificates for 2012-2017 to track migration, vital status, and cause of death. PARTICIPANTS: 5,068,414 individuals living as a couple, as registered in the census, and aged ≥69 years on January 1, 2012. MEASUREMENTS: Mortality rate ratios (MRR) estimated through Poisson regression models were used to compare suicide mortality at age ≥75 years between subjects who experienced partner loss and those who did not. RESULTS: Among people who experienced partner loss, there were 383 suicide deaths in men and 90 in women. Suicide mortality was higher in older men and women who experienced the loss compared to those who did not, and the impact of the spouse loss on mortality was stronger in men (age-adjusted MRR=2.83) than in women (1.41). Among men the excess risk was particularly high during the first year following the loss; in women, no substantial differences in the excess risk were observed over the follow-up period. CONCLUSION: Study findings provide evidence of the sex differences in the impact of spouse loss based on data from a large national cohort and reinforce the need for monitoring suicide risk in recently widowed older people.

Suicide mortality among the elderly population in Italy: A nationwide cohort study on gender differences in sociodemographic risk factors, method of suicide, and associated comorbidity.

OBJECTIVES: This study aimed at investigating gender differences in the relationship between sociodemographic factors and suicide mortality, as well as in the method used for suicide and the presence of comorbidities in an older population in Italy. METHODS/DESIGN: We conducted a historical cohort study based on individual record linkage across the 15th Italian Population Census, the Italian Population Register, and the National Register of Causes of Death. Suicides among people aged 75 years or older from 2012 to 2017 were analyzed. Crude mortality rates were computed, and cause-specific mortality rate ratios were estimated using negative binomial regression models. Chi-square tests were used to evaluate significant gender differences in suicide methods and comorbidities associated with suicide. RESULTS: The study included 9,686,698 individuals (41% men, 59% women). Compared to living alone, living with children or partners reduced suicide mortality, especially among men. Having high or medium educational levels was associated with lower mortality than low educational levels among men. Foreign citizens had lower mortality among men, but not among women. Living in urban areas was associated with lower suicide rates in men and higher rates in women. Methods of suicide significantly differed by gender: leading methods were hanging, strangulation, and suffocation in men, and falling from height in women. Mental comorbidity was significantly more frequent among women, especially at ages 75-84 years. CONCLUSIONS: We believe that our findings might help to promote public health strategies taking gender differences in old age into account to improve social support and quality of life of older men and women.

Completed suicide during pregnancy and postpartum.

Both pregnancy and the postpartum are typical periods for the onset or relapse of psychiatric symptoms and disorders, with depression and anxiety being the most common. The prevalence of suicide spectrum behaviour is significantly higher among women with a diagnosis of depressive or bipolar disorder. Suicide during pregnancy and postpartum is a multifactorial phenomenon and a history of psychiatric illness is only one of the possible risk factors involved in suicide spectrum behaviour. The present paper highlights the importance of a complete screening for both depression and suicide risk during peripartum.

Trends and ecological results in suicides among Italian youth aged 10-25 years: A nationwide register study.

BACKGROUND: Documenting current trends and sources of variation in youth suicide rates is critical to inform prevention strategies. We aimed to document suicide mortality trends among Italian youth from 1981 to 2016 and to describe age-, gender- and urbanization-specific suicide rates. METHODS: We used official mortality data for the period 1981-2016 for adolescents and young adults aged 10-25 years. We estimated standardized all-cause and suicide mortality rates per 100,000 individuals and used joinpoint regression analyses to determine annual mortality trends and significant changes in rate trends. Analyses were reported according to gender, age group (10-17 and 18-25 years), urbanization and suicide method. RESULTS: From 1981 to 2016, 1,752 suicides were identified among youth aged 10-17 years (boy/girl ratio of 5.80 in 2016) and 9,897 suicides among youth aged 18-25 years (boy/girl ratio of 3.97 in 2016). Overall suicide rates remained stable for boys and showed a small decrease for girls. Suicide was most common in rural areas for boys and in metropolitan areas for girls. We observed a significant decrease in the use of firearms and poisoning; the most common suicide method was hanging for boys and falls for girls. LIMITATIONS: We did not control for regional-level sociodemographic, economic and health care system characteristics. CONCLUSIONS: Youth suicides were either stable (for boys) or slightly declining (for girls). We found differences according to urban versus rural areas, suggesting the need for a broader view of the phenomenon. Factors influencing these trends and gender differences in the geographical areas are important in delivering suicide prevention strategies.

Suicide among adolescents in Italy: a nationwide cohort study of the role of family characteristics.

Suicide is a leading cause of death among adolescents and is recognized as a serious public health problem. This study aimed to investigate the relationship between family characteristics and the risk of suicide among adolescents in Italy using nationwide official data. We carried out a cohort study based on the record linkage between the 15th Italian Population Census, the Italian Population Register, and the National Register of Causes of Death. Suicides in adolescents aged 10-19 years from 2012 to 2016 were analyzed. Hazard ratios of mortality from suicide were estimated through a multivariable Cox regression model using time-on-study as the time scale. We included 8,284,359 children and adolescents (51% males, 49% females). Over the 5-year follow-up, we registered 330 deaths from suicides (74% males), mostly occurred in the age class 15-19 years (86%). The suicide rate was 1.71 per 100,000 person-years among males and 0.65 among females. We found some familial characteristics associated with a higher risk of dying by suicide, including: living in single-parent or reconstructed families (among boys), a 40-year or more age gap between mother and child (among girls), having highly educated parents, an age difference between parents greater than 5 years. Furthermore, the study showed a lower risk for boys living in urban areas and for both boys and girls living in South Italy. Our results could help in identifying adolescents at high risk of suicide who could benefit from the planning of targeted intervention strategies.

Does population density moderate suicide risk? An Italian population study over the last 30 years.

BACKGROUND: The relationship between population density and suicide risk remains unclear. While urbanization is associated with greater risk for psychopathology, higher suicide rates have been reported in rural areas. We examined population density and suicide in the Italian population in the last 30 years. METHODS: The Italian National Institute of Statistics databases of the Italian population aged 15 years and older (52.4 million in 2016) were used to compute age-adjusted annual total mortality and suicide rates for the years 1985-2016. According to the European Union statistical office (EUROSTAT) criteria, municipalities were classified into densely populated areas, intermediate density areas, or thinly populated areas. Rate ratios (RRs) were computed by sex, age, and geographical area, using densely populated areas as reference. RESULTS: Total mortality was not associated with population density. In males, suicide rate increased with decreasing population density (RR = 1.17, 95% confidence interval [CI]:1.08-1.28, in intermediate population areas, and RR = 1.32, 95% CI: 1.20-1.45, in thinly populated areas, in 2016). This inverse relationship was found across age, geographical areas, and consecutively over 22 years (1994-2016). In females, no significant difference was detected (RR = 0.96, 95% CI: 0.82-1.13 in intermediate density areas and RR = 1.02, 95% CI: 0.85-1.22 in thinly populated areas). Hanging was the most common suicide method among males, more frequent in thinly (58.8%) than intermediate (53.2%) or densely (41.4%) populated areas. CONCLUSIONS: A consistent and temporally stable inverse relationship between population density and suicide was found in the male, but not female, population. Men may be more vulnerable to adverse social and economic factors associated with lower population density.

Trends and patterns in homicides in Italy: A 34-year descriptive study.

AIMS: We aimed at analyzing homicide trends and patterns in Italy over the period 1980-2014. METHODS: We collected data from the Italian Mortality Database (Italian National Institute of Statistics), for the study period. Temporal trends were analyzed using joinpoint regression analysis, with estimated annual percentage change computed for each detected trend. The possible effect of the mafia subculture was examined using an indicator of mafia social penetration. Differences between age classes, genders, geographical regions, and homicide methods were also analyzed. RESULTS: The analyses showed an overall reduction in homicides during the study period, including a reduction in homicides by firearm. Further, we found significant differences between homicides involving male and female victims. A peak in male homicides, observed in the early 1990s, was significantly associated with mafia penetration. CONCLUSIONS: The overall reduction in homicides can be interpreted as an expression of a "civilizing process."

Late life suicide in Italy, 1980-2015.

AIM: Suicide trends in older adults were examined in Italy from 1980 to 2015. Age groups considered were 65-74 years, 75-84 and 85 + years. METHODS: Data on suicide deaths were obtained from the Italian Mortality Database (IMDB) collected by the Italian National Institute of Statistics (ISTAT) and processed by the Statistics Unit of the Italian National Institute of Health (Istituto Superiore di Sanità). Joinpoint regression analyses were carried out for age subgroups by sex. In addition, data related to four main macro-areas of Italy were considered: North-West, North-East, Centre, and South with Islands (Sicily and Sardinia). RESULTS: Starting by 1985, declines were noted in all age groups with more noticeable decreases in older adults aged 75-84 and 85 + years. Female subjects demonstrated more ample falls in rates than male individuals. Declines were detected in all macro-areas of Italy. CONCLUSION: Improved health assistance and quality of life of older individuals have probably contributed to the decline of suicide rates of senior citizens, who also showed improved poverty indices in the country, differently from all other age groups.

Maternal suicide in Italy.

Suicide has been identified as one of the most common causes of death among women within 1 year after the end of pregnancy in several high-income countries. The aim of this study was to provide the first estimate of the maternal suicide ratio and a description of the characteristics of women who died by suicide during pregnancy or within 1 year after giving birth, induced abortion or miscarriage (i.e., maternal suicide) in 10 Italian regions, covering 77% of total national births. Maternal suicides were identified through the linkage between regional death registries and hospital discharge databases. Background population data was collected from the national hospital discharge, abortion and mortality databases. The previous psychiatric history of the women who died by maternal suicide was retrieved from the regionally available data sources. A total of 67 cases of maternal suicide were identified, corresponding to a maternal suicide ratio of 2.30 per 100,000 live births in 2006-2012. The suicide rate was 1.18 per 100,000 after giving birth (n = 2,876,193), 2.77 after an induced abortion (n = 650,549) and 2.90 after a miscarriage (n = 379,583). The majority of the women who died by maternal suicide (34/57) had a previous psychiatric history; 15/18 previously diagnosed mental disorders were not registered along with the index pregnancy obstetric records. Suicide is a relevant cause of maternal death in Italy. The continuity of care between primary, mental health and maternity care were found to be critical. Clinicians should be aware of the issue, as they may play an important role in preventing suicide in their patients.

Arsenic: Association of regional concentrations in drinking water with suicide and natural causes of death in Italy.

Arsenic, as a toxin, may be associated with higher mortality rates, although its relationship to suicide is not clear. Given this uncertainty, we evaluated associations between local arsenic concentrations in tapwater and mortality in regions of Italy, to test the hypothesis that both natural-cause and suicide death rates would be higher with greater trace concentrations of arsenic. Arsenic concentrations in drinking-water samples from 145 sites were assayed by mass spectrometry, and correlated with local rates of mortality due to suicide and natural causes between 1980 and 2011, using weighted, least-squares univariate and multivariate regression modeling. Arsenic concentrations averaged 0.969 (CI: 0.543-1.396) µg/L, well below an accepted safe maximum of 10µg/L. Arsenic levels were negatively associated with corresponding suicide rates, consistently among both men and women in all three study-decades, whereas mortality from natural causes increased with arsenic levels. Contrary to an hypothesized greater risk of suicide with higher concentrations of arsenic, we found a negative association, suggesting a possible protective effect, whereas mortality from natural causes was increased, in accord with known toxic effects of arsenic. The unexpected inverse association between arsenic and suicide requires further study.

A Google-based approach for monitoring suicide risk.

People seeking information and news regarding suicide are likely to use the Internet. However, evidence of the relationship between suicide-related search volumes and national suicide-rates in different countries can be strikingly different. We aimed to investigate the relationship between suicide-rates and Google suicide-related search volumes in the Italian population (2008-2012) using the Italian mortality database that provided monthly national data concerning suicides (2008-2012). Moreover, this study aimed to identify future trends of national suicide rates on the basis of the results we obtained concerning the period 2013-14. Google Trends provided data of online monthly search-volumes of the term "suicide", "commit suicide" and "how to commit suicide" in Google Search and Google News (2008-2014). Google Search volumes for the term "suicide" lags suicide by three months (ρ=0.482, p-value<0.001), whereas no correlation was found between search volumes for "commit suicide" and "how to commit suicide" and national suicide rates. Google News search volumes for the three terms resulted in white noise. Apparently, online searches for suicide-related terms in Italy are more likely to be linked to factors other than suicidiality such as personal interest and suicide bereavement.

Relationship of suicide rates with climate and economic variables in Europe during 2000-2012.

BACKGROUND: It is well known that suicidal rates vary considerably among European countries and the reasons for this are unknown, although several theories have been proposed. The effect of economic variables has been extensively studied but not that of climate. METHODS: Data from 29 European countries covering the years 2000-2012 and concerning male and female standardized suicidal rates (according to WHO), economic variables (according World Bank) and climate variables were gathered. The statistical analysis included cluster and principal component analysis and categorical regression. RESULTS: The derived models explained 62.4 % of the variability of male suicidal rates. Economic variables alone explained 26.9 % and climate variables 37.6 %. For females, the respective figures were 41.7, 11.5 and 28.1 %. Male suicides correlated with high unemployment rate in the frame of high growth rate and high inflation and low GDP per capita, while female suicides correlated negatively with inflation. Both male and female suicides correlated with low temperature. DISCUSSION: The current study reports that the climatic effect (cold climate) is stronger than the economic one, but both are present. It seems that in Europe suicidality follows the climate/temperature cline which interestingly is not from south to north but from south to north-east. This raises concerns that climate change could lead to an increase in suicide rates. The current study is essentially the first successful attempt to explain the differences across countries in Europe; however, it is an observational analysis based on aggregate data and thus there is a lack of control for confounders.

Economic Deprivation as a Predictor of the Direction of Lethal Violence: An Analysis of Italian Provinces.

Research on suicide and homicide rates has neglected an integrated model seeking to explain social variation in the direction of lethal violence. The present investigation explores the association between measures of social deprivation on the relative incidence of suicide over homicide in Italian provinces. Data refer to official government sources on lethal violence rates and measures of social deprivation. The central dependent variable (SHR) is the tendency towards suicide measured as the suicide rate divided by the sum of the suicide and homicide rates. Data were available for 102 Italian provinces in the Census year 2001. The percentage of the population marked by two indicators of deprivation (low education, household population density) were negatively associated with the SHR. The results are largely consistent with a stream of previous research that connects deprivation with a relatively high probability for disadvantaged populations to direct aggression outwardly in the form of homicide rather than inwardly in the form of suicide. The present study specifies which elements of deprivation best predict the direction of violence and is the first study for the Italian context.

Relationships of local lithium concentrations in drinking water to regional suicide rates in Italy.

OBJECTIVES: Higher natural concentrations of lithium in drinking water may be associated with lower local rates of suicide. METHODS: Lithium concentrations in drinking water were assayed by mass spectrometry at 145 sites in Italy, and compared with reported local suicide rates for men and women between 1980 and 2011. RESULTS: Lithium concentrations in drinking water averaged 5.28 [CI: 4.08-6.48] µg/L (0.761 [0.588-0.934] µEq/L) and ranged from 0.110 to 60.8 µg/L (1.58 to 8.76 µEq/L). Lithium concentrations and local suicide rates were not significantly inversely related, except in 1980-1989, particularly among women. CONCLUSIONS: A proposed association between trace lithium concentrations in drinking water and risk of suicide was only partially supported, and mechanisms for potential clinical effects of trace levels of lithium are unknown.

Relationship of suicide rates to economic variables in Europe: 2000-2011.

BACKGROUND: It is unclear whether there is a direct link between economic crises and changes in suicide rates. AIMS: The Lopez-Ibor Foundation launched an initiative to study the possible impact of the economic crisis on European suicide rates. METHOD: Data was gathered and analysed from 29 European countries and included the number of deaths by suicide in men and women, the unemployment rate, the gross domestic product (GDP) per capita, the annual economic growth rate and inflation. RESULTS: There was a strong correlation between suicide rates and all economic indices except GPD per capita in men but only a correlation with unemployment in women. However, the increase in suicide rates occurred several months before the economic crisis emerged. CONCLUSIONS: Overall, this study confirms a general relationship between the economic environment and suicide rates; however, it does not support there being a clear causal relationship between the current economic crisis and an increase in the suicide rate.

An easy, fast, effective tool to monitor the incidence of type 1 diabetes among children aged 0-4 years in Italy: the Italian Hospital Discharge Registry (IHDR).

National data of type 1 diabetes incidence are currently missing in Italy. To fill this gap, we estimated the national rate of first hospitalizations for type 1 diabetes among children aged 0-4 years and resident in Italy, as well as rates for each of the twenty-one Italian regions. We extracted the first episode of hospitalization in years 2005-2010 from the Italian Hospital Discharge Registry (IHDR). Record-linkage procedure and cleansing data method were applied to exclude prevalent cases and potentially miscoded patients. At the end, 2,250 incident hospitalizations for type 1 diabetes were extracted. In the years 2005-2010, the mean nation-wide first hospitalization rate for type 1 diabetes in children aged 0-4 years was 13.4 (95% CI 12.8-14.0), 14.1 (95% CI 13.3-14.9) in males and 12.7 (95% CI 11.9-13.4) in females. A geographically heterogeneous pattern of incidence was found: even excluding Sardinia, incidence for this age range and calendar period tended to be slightly higher in Southern than in Northern Italy. Our incidence of first hospitalizations corresponds to the estimates of disease incidence obtained with different data sources by other authors in selected Italian regions. We provide, for the first time ever, the estimate of type 1 diabetes incidence for the overall population aged 0-4 years resident in Italy. When methodological cautions are adopted, IHDR emerges as a reasonable proxy of type 1 diabetes incidence and as a cost-effective tool for public health purposes.

Suicide in Italy during a time of economic recession: some recent data related to age and gender based on a nationwide register study.

Previous research reported that economic crises may have important implications for increasing suicide rates. We investigated official data on completed suicide in Italy during the recent economic crisis as related to age and gender. Data were extracted from the Italian Mortality Database. The trend in suicide rates from 1980 to 2010 (the most recent year available) was analysed by joinpoint regression analysis. Rate ratios were calculated to compare suicide rates before and after the present economic crisis. Suicide rates for men 25-64 years of age (those involved in the labour force) started to increase in 2008 after a period of a statistically significant decrease from 1994 to 2007 and their suicide rate was 12% higher in 2010 compared with that in 2006. In contrast, suicide rates declined for women of all ages and for men younger than 25 and older than 65 years of age. After 2007, there was a noticeable increase in suicide rates among Italian men involved in the labour force.

Does the level of education influence completed suicide? A nationwide register study.

OBJECTIVE: To evaluate whether education attainment was associated with completed suicide, a topic only marginally investigated in the literature. METHODS: Data for the years between 2006 and 2008 were extracted from the Italian Mortality Database to include all deaths by suicide and natural causes and to obtain information on their education attainment. RESULTS: We found significant differences in education attainment between suicide victims and individuals deceased by natural causes, stratified by sex and broken down by age bands. Of both males and females from 15 to 64 years old, suicide victims were significantly more often to have a higher education attainment compared with the same sex and age counterparts died from natural causes. Persons with higher school attainment, compared with those with a maximum primary school degree, had significantly increased odds ratios of dying from a suicide rather than a natural cause. For persons aged 65-74 years or above, however, the differences were not so much obvious. These observations remained almost the same after adjustment for marital status, region of residence and age. CONCLUSIONS: Individual with higher educational achievement may be more prone to suicide risk when facing failures, public shame, and high premorbid functioning.

A longitudinal epidemiological comparison of suicide and other causes of death in Italian children and adolescents.

The objective of the study is to evaluate temporal trends, gender effects and methods of completed suicide amongst children and adolescent (aged 10-17) when compared with temporal trends of deaths from other causes. Data were extracted from the Italian Mortality Database, which is collected by the Italian National Census Bureau (ISTAT) and processed by the Statistics Unit of National Centre for Epidemiology, Surveillance and Health Promotion (CNESPS) at the National Institute of Health (Istituto Superiore di Sanità). A total of 1,871 children and adolescents, age 10-17 years, committed suicide in Italy from 1971 to 2003 and 109 died by suicide during the last 3-year period of observation (2006-2008). The average suicide rate over the entire period of observation was 0.91 per 100,000; the rate was 1.21 for males and 0.59 for females. During the study period, the general mortality of children and adolescents, age 10-17 years, decreased dramatically, the average annual percentage change decrease was of -3.3% (95% CI -4.4 to -1.9) for males and -2.9% (95% IC -4.4 to -2.5) for females. The decrease was observed, for both genders, for all causes of deaths except suicide. For males, the most frequent method was hanging (54.5%), followed by shooting/fire arms (19.6%), falls/jumping from high places (12.7%); for females, the most frequent method, jumping from high places/falls, accounted for 35.7% of suicides during the whole study period. In conclusion, this study highlights that over the course of several decades suicide is a far less preventable cause of death as compared to other causes of death amongst children and adolescents. Our study demonstrated that suicide rates in adolescents are not a stable phenomenon over the 40 years period of study. It suggested that rates for males and females differed and varied in different ways during specific time periods of this study. National suicide prevention actions should parallel prevention measures implemented to reduce other causes of death.
