RESUMEN
Background: Suicide is a serious but preventable public health concern at the global level, showing relevant geographical differences. This study aims to monitor global temporal and geographical patterns in suicide mortality in pre-adolescents, adolescents, and young adults (i.e., aged 10-24 years), from 1990 to 2020 or the most recent available year. Methods: Using the World Health Organisation mortality database, we conducted an analysis on a subset of 52 countries with valid and high-quality data. We computed age-standardised suicide rates (ASR) by sex, country, and calendar year, and performed a joinpoint regression analysis to identify significant changes in the temporal suicide trends over the studied period. Findings: High variability in suicide rates and trends was observed, with a male-to-female ratio of two to five. Between 1990 and 2020, most European countries reported declining suicide trends, with some exceptions. In particular, alarming trends emerged in the United Kingdom, with annual rises of 2.5% (95% CI: 1.6-3.5) since 2005 among males and 8.5% (95% CI: 4.7-12.6) since 2012 among females. The most favorable trends and lowest suicide rates were in Southern Europe, with 3.1/100,000 persons in Italy (2020) and 3.5/100,000 persons in Spain (2021) among males, and 0.9/100,000 persons in Italy (2020) and 1.1/100,000 persons in Romania (2019) among females. Conversely, the highest rates were in Central-Eastern Europe, with 10.2/100,000 males in the Russian Federation (2019) and 10.0/100,000 males in Poland (2002). Higher suicide rates and significant increases were reported in not European areas. The highest ASR was 15.5/100,000 males in the United States of America, with an annual increase of 3.8% (95% CI: 3.1-4.5) among males in 2009-2020 and 6.7% (95% CI: 5.6-7.8) among females in 2007-2017, followed by a levelling off. Interpretation: Temporal and geographical comparisons of suicide mortality should be interpreted with caution due to potential misclassification or under-reporting of suicide deaths in some countries. Funding: None.
RESUMEN
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.

Prepandemic time trends in mortality from chronic liver disease (CLD) differed according to specific cause of death (decreasing for liver cirrhosis, stable or increasing for liver cancer), etiology (increasing for nonalcoholic fatty liver disease, generally decreasing for other etiologies), and world region (decreasing in areas with the highest burden of hepatitis B virus, increasing in Eastern Europe and other countries). The coronavirus disease 2019 (COVID-19) pandemic affected mortality of patients with CLD both directly, with a higher risk for severe illness and death depending on age, stage and etiology of the disease, and indirectly, through social isolation and loss of support, harmful drinking, and difficulties in access to care. Nevertheless, only sparse data are available on variations in CLD as a cause of death during the pandemic. In the USA, in 2020-2021 a growth in mortality was registered for all liver diseases, more marked for alcoholic liver disease, especially among young people aged 25-44 years and in selected ethnic groups. COVID-19 related deaths accounted only for a minor part of the excess. Further data from mortality registers of other countries are warranted, preferably adopting the so-called multiple cause-of-death approach, and extended to deaths attributed to viral hepatitis and liver cancer.

BACKGROUND: Italy was severely hit by COVID-19 during 2020 and great concern about the possible increase of suicide rates in the population has arisen since early pandemic phases. Analyses limited to March-April have shown a drop in suicides in both sexes. This study aims to analyze suicide mortality in Italy during the whole 2020 making comparisons with the pre-pandemic period 2015-19, by sex, age and geographic area. METHODS: Official cause-of-death data with national coverage were used to analyze suicide mortality by sex, month, age class and geographic area in the population aged ≥10 years (54,595,179). The monthly number of suicide deaths in 2020 was compared to the average number in 2015-19. Age-specific and age-adjusted suicide rates in 2020 and in 2015-19 were compared using rate-ratios with 95 % confidence intervals. RESULTS: Compared to 2015-19 a non-significant reduction of the overall suicide rate was observed during 2020, both in males (-3 %) and females (-7 %). Suicide rates non-significantly decreased in most age groups; an increase, although not statistically significant, was found among males aged ≥75 years and females aged ≥85 years. Suicide deaths reduced mainly in Central-Southern areas and the Islands, while they slightly increased in the North especially among males. LIMITATIONS: Study limitations include accuracy of death certification and the relatively brief observation period. CONCLUSIONS: The study contributes to the analysis of early effects of the COVID-19 pandemic on suicide mortality in the whole population highlighting sex, age and territorial differences and suggesting to monitor possible increases in a longer observation period.

Background and aim: Patients with interstitial lung diseases, including asbestosis, showed high susceptibility to the SARS-CoV-2 virus and a high risk of severe COVID-19 symptoms. Italy, highly impacted by asbestos-related diseases, in 2020 was among the European countries with the highest number of COVID-19 cases. The mortality related to malignant mesotheliomas and asbestosis in 2020 and its relationship with COVID-19 in Italy are investigated. Methods: All death certificates involving malignant mesotheliomas or asbestosis in 2010-2020 and those involving COVID-19 in 2020 were retrieved from the National Registry of Causes of Death. Annual mortality rates and rate ratios (RRs) of 2020 and 2010-2014 compared to 2015-2019 were calculated. The association between malignant pleural mesothelioma (MPM) and asbestosis with COVID-19 in deceased adults ≥80 years old was evaluated through a logistic regression analysis (odds ratios: ORs), using MPM and asbestosis deaths COVID-19-free as the reference group. The hospitalization for asbestosis in 2010-2020, based on National Hospital Discharge Database, was analyzed. Results: In 2020, 746,343 people died; out of them, 1,348 involved MPM and 286 involved asbestosis. Compared to the period 2015-2019, the mortality involving the two diseases decreased in age groups below 80 years; meanwhile, an increasing trend was observed in subjects aged 80 years and older, with a relative mortality risks of 1.10 for MPM and 1.17 for asbestosis. In subjects aged ≥80 years, deaths with COVID-19 were less likely to have MPM in both genders (men: OR = 0.22; women: OR = 0.44), while no departure was observed for asbestosis. A decrease in hospitalization in 2020 with respect to those in 2010-2019 in all age groups, both considering asbestosis as the primary or secondary diagnosis, was observed. Conclusions: The increasing mortality involving asbestosis and, even if of slight entity, MPM, observed in people aged over 80 years during the 1st year of the COVID-19 pandemic, aligned in part with the previous temporal trend, could be due to several factors. Although no positive association with COVID-19 mortality was observed, the decrease in hospitalizations for asbestosis among individuals aged over 80 years, coupled with the increase in deaths, highlights the importance of enhancing home-based assistance during the pandemic periods for vulnerable patients with asbestos-related conditions.

OBJECTIVES: This study aimed to assess whether an excess mortality related to kidney and other urinary tract diseases exists among Italian people with AIDS (PWA), as compared with the general population without AIDS (non-PWA). DESIGN: Population-based, retrospective cohort study. SETTING AND PARTICIPANTS: We conducted a nationwide study including 9481 Italian PWA, aged 15-74 years, reported to the National AIDS Registry between 2006 and 2018. METHODS: Vital status and causes of death were retrieved by record linkage with the National Register of Causes of Death up to 2018. Excess mortality for PWA versus non-PWA was estimated through sex-standardised and age-standardised mortality ratios (SMRs) with corresponding 95% CIs. RESULTS: Among 2613 deceased PWA, 262 (10.0%) reported at least one urinary tract disease at death, including 254 (9.7%) non-cancer diseases-mostly renal failures (225 cases, 8.6%)-and 9 cancers (0.3%). The overall SMR for non-cancer urinary tract diseases was 15.3 (95% CI 13.4 to 17.3) with statistically significant SMRs for acute (SMR=22.3, 95% CI 18.0 to 27.4), chronic (SMR=8.4, 95% CI 6.0 to 11.3), and unspecified renal failure (SMR=13.8, 95% CI 11.2 to 16.8). No statistically significant excess mortality was detected for urinary tract cancers (SMR=1.7, 95% CI 0.8 to 3.3). The SMRs were particularly elevated among PWA aged <50 years, injecting drug users, or those with the first HIV-positive test >6 months before AIDS diagnosis. CONCLUSIONS: The excess mortality related to non-cancer kidney and other urinary tract diseases reported among PWA highlights the importance of implementing the recommendation for screening, diagnosis and management of such conditions among this population.

Mortality related to chronic obstructive pulmonary disease (COPD) during the COVID-19 pandemic is possibly underestimated by sparse available data. The study aimed to assess the impact of the pandemic on COPD-related mortality by means of time series analyses of causes of death data. We analyzed the death certificates of residents in Veneto (Italy) aged ≥40 years from 2008 to 2020. The age-standardized rates were computed for COPD as the underlying cause of death (UCOD) and as any mention in death certificates (multiple cause of death-MCOD). The annual percent change (APC) in the rates was estimated for the pre-pandemic period. Excess COPD-related mortality in 2020 was estimated by means of Seasonal Autoregressive Integrated Moving Average models. Overall, COPD was mentioned in 7.2% (43,780) of all deaths. From 2008 to 2019, the APC for COPD-related mortality was -4.9% (95% CI -5.5%, -4.2%) in men and -3.1% in women (95% CI -3.8%, -2.5%). In 2020 compared to the 2018-2019 average, the number of deaths from COPD (UCOD) declined by 8%, while COPD-related deaths (MCOD) increased by 14% (95% CI 10-18%), with peaks corresponding to the COVID-19 epidemic waves. Time series analyses confirmed that in 2020, COPD-related mortality increased by 16%. Patients with COPD experienced significant excess mortality during the first year of the pandemic. The decline in COPD mortality as the UCOD is explained by COVID-19 acting as a competing cause, highlighting how an MCOD approach is needed.

OBJECTIVES: to evaluate the impact on total mortality of the COVID-19 pandemic in Italy, by country of birth. DESIGN: historic cohort study based on administrative databases. SETTING AND PARTICIPANTS: the study is based on subjects included in the Base Register of Individuals of the Italian National Institute of Statistics on 01.01.2019, aged 35-64 years, and followed-up until 31.07.2021. MAIN OUTCOME MEASURES: age-standardized mortality rates were computed to analyse trends in overall mortality by country of birth grouped in three categories: 1. Italy and other high developed countries; 2. European countries with strong migratory pressure (EU-SMP); 3, non-European countries with strong migratory pressure (non-EU-SMP). Variations in mortality rates during the pandemic (March 2020-July 2021) with respect to the pre-pandemic period (January 2019-February 2020) were measured and compared across groups using mortality rate ratios (MRR) estimated by Poisson regression models, separately for men and women. RESULTS: the cohort includes 26,199,241 individuals, of whom 172,847 died during the follow-up. Over the whole period, mortality was consistently lower in individuals born in non-EU-SMP countries as compared to those born in Italy and other high developed countries. During the first pandemic wave (March-April 2020), individuals born in non-EU-SMP countries had higher excesses as compared to those born in Italy or other high developed countries (MRRs: 1.42 vs 1.28 in men and 1.30 vs 1.11 in women). Similar results were observed during the pandemic period October 2020-April 2021, when the MRRs were 1.37 vs 1.20 in men and 1.30 vs 1.11 in women. In the same period, the excess mortality among individuals born in EU-SMP did not significantly differ from that observed among those born in Italy and other high developed countries. CONCLUSIONS: in Italy, excess mortality during the COVID-19 pandemic was higher among immigrants born in non-EU-SMP countries as compared to the native population and immigrants born in high developed countries.

A systematic analysis of the mortality of immigrant residents throughout Italy has never been carried out. The present study aimed to evaluate differences in mortality by immigrant status. A longitudinal study of the Italian resident population (native and immigrants) recorded in the 2011 National Institute of Statistics Census was conducted. This cohort was followed up from 2012 to 2018 until death, emigration, or end of the study period. The exposure variable was the immigrant status, measured through citizenship, dichotomized into Italian and immigrant. The main outcome was overall and cause-specific mortality. Age-standardized mortality ratios (SMRs) were calculated. The SMRs among immigrants were half that of Italians, both for men (SMR 0.52) and women (SMR 0.51), with the lowest SMRs observed for subjects from North Africa and Oceania. For some causes of death, mortality was higher among immigrants: tuberculosis in both men (SMR 4.58) and women (SMR 4.72), and cervical cancer (SMR 1.58), complications of pregnancy, childbirth, and puerperium (SMR 1.36), and homicide (SMR 2.13) for women. A multivariable quasi-Poisson regression analysis, adjusted for age and macro area of residence in Italy, confirmed a lower all-cause mortality for immigrants compared to Italians, both for men (RR 0.46) and women (RR 0.44). Although immigration to Italy is no longer a recent phenomenon, and the presence of immigrants is acquiring structural characteristics, our study confirms their health advantage, with a lower mortality than that of Italians for almost all causes of death and for all areas of origin.

AIMS: To assess whether the use of multiple cause-of-death data could improve reporting of AIDS mortality in Italy. METHOD: Population-based, record-linkage study, on 3,975,431 deaths recorded in the National Registry of Causes of Death (RCoD) and 4,530 deaths recorded in the National AIDS Registry (RAIDS), during 2006-2012. RESULTS: The record-linkage identified 3,646 AIDS-related deaths present in both registries, 884 deaths in the RAIDS without mention of HIV/AIDS in the RCoD, and 3,796 deaths in the RCoD with mention of HIV/AIDS that were not present in the RAIDS. In the latter, in-depth analysis of multiple cause-of-death allowed the identification of 1,484 deaths that were AIDS-related. On these results, we estimated 6,014 deceased people with AIDS. Of them, 14.7% (884) were not present in the RCoD and 24.7% (1,484) derived from the RCoD only. CONCLUSIONS: The integration of different nationwide registries allowed a more comprehensive estimate of the impact of AIDS-associated mortality in Italy.

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.

Italy was a country severely hit by the first coronavirus disease 2019 (COVID-19) pandemic wave in early 2020. Mortality studies have focused on the overall excess mortality observed during the pandemic. This paper investigates the cause-specific mortality in Italy from March 2020 to April 2020 and the variation in mortality rates compared with those in 2015-2019 regarding sex, age, and epidemic area. Causes of death were derived from the national cause-of-death register. COVID-19 was the leading cause of death among males and the second leading cause among females. Chronic diseases, such as diabetes and hypertensive, ischemic heart, and cerebrovascular diseases, with decreasing or stable mortality rates in 2015-2019, showed a reversal in the mortality trend. Moreover, mortality due to pneumonia and influenza increased. No increase in neoplasm mortality was observed. Among external causes of death, mortality increased for accidental falls but reduced for transport accidents and suicide. Mortality from causes other than COVID-19 increased similarly in both genders and more at ages 65 years or above. Compared with other areas in Italy, the Lombardy region showed the largest excess in mortality for all leading causes. Underdiagnosis of COVID-19 at the beginning of the pandemic may, to some extent, explain the mortality increase for some causes of death, especially pneumonia and other respiratory diseases.

BACKGROUND: Chronic kidney diseases (CKDs) represent a major public health concern worldwide with increasing incidence and prevalence. However, the epidemiological dimension of CKD in Italy is still under evaluation. By analyzing all the conditions reported on death certificates (multiple causes of death), we aimed to investigate the real burden of CKD mortality in Italy over 15 years and identify the main conditions contributing to death in association with CKD. METHODS: Death certificates of all deaths occurring in Italy from 2003 to 2017 were analyzed. Certificates reporting CKD were identified as CKD-related deaths. CKD-related mortality was investigated through age-standardized mortality rates, by sex and age. Conditions associated with CKD were identified through an indicator (age-standardized proportion ratio) measuring the excess proportion (value > 1) of having such conditions mentioned in the death certificate with and without CKD. RESULTS: From 2003 to 2017, multiple-cause-based CKD mortality rates increased by 60% in males and by 54% in females. The overall increase was mostly attributable to people aged 80 years or more. Several conditions were associated with CKD, the most relevant being diabetes (age-standardized proportion ratio = 2.2), obesity (2.1), systemic connective tissue disorders (2.3), anemia (2.7), and genitourinary system diseases (2.6). CONCLUSIONS: Multiple-cause-of-death data revealed a significant increase in CKD-related mortality in recent years, providing a measure of the burden of CKD on overall mortality in Italy. Moreover, multiple cause analysis allowed to identify the main conditions contributing to death in association with CKD, which should be aggressively targeted by clinicians to prevent CKD adverse outcomes.

Background: In Italy, during the first epidemic wave of 2020, the peak of coronavirus disease 2019 (COVID-19) mortality was reached at the end of March. Afterward, a progressive reduction was observed until much lower figures were reached during the summer, resulting from the contained circulation of SARS-CoV-2. This study aimed to determine if and how the pathological patterns of the individuals deceased from COVID-19 changed during the phases of epidemic waves in terms of: (i) main cause of death, (ii) comorbidities, and (iii) complications related to death. Methods: Death certificates of persons who died and tested positive for SARS-CoV-2, provided by the National Surveillance system, were coded according to ICD rev10. Deaths due to COVID-19 were defined as those in which COVID-19 was the underlying cause of death. Results: The percentage of COVID-19 deaths varied over time. It decreased in the downward phase of the epidemic curve (76.6 vs. 88.7%). In February-April 2020, hypertensive heart disease was mentioned as a comorbidity in 18.5% of death certificates, followed by diabetes (15.9% of cases), ischemic heart disease (13.1%), and neoplasms (12.1%). In May-September, the most frequent comorbidity was neoplasms (17.3% of cases), followed by hypertensive heart disease (14.9%), diabetes (14.8%), and dementia/Alzheimer's disease (11.9%). The most mentioned complications in both periods were pneumonia and respiratory failure with a frequency far higher than any other condition (78.4% in February-April 2020 and 63.7% in May-September 2020). Discussion: The age of patients dying from COVID-19 and their disease burden increased in the May-September 2020 period. A more serious disease burden was observed in this period, with a significantly higher frequency of chronic pathologies. Our study suggests better control of the virus' lethality in the second phase of the epidemic, when the health system was less burdened. Moreover, COVID-19 care protocols had been created in hospitals, and knowledge about the diagnosis and treatment of COVID-19 had improved, potentially leading to more accurate diagnosis and better treatment. All these factors may have improved survival in patients with COVID-19 and led to a shift in mortality to older, more vulnerable, and complex patients.
RESUMEN
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.

OBJECTIVES: Excess risk of suicide has been reported among workers in agriculture, fishery, forestry and hunting (AFFH). However, there is still uncertainty in the quantification of the risk and in the contribution of work-related factors. We aimed to quantify the suicide mortality risk among these workers in Italy. METHODS: We carried out a historical cohort study based on record linkage between the 2011 Italian census and the mortality archives for years 2012-2017. The mortality rate ratio (MRR) was used as a measure of risk. MRR was estimated through quasi-Poisson regression models using workers in other sectors as reference category. Models were adjusted for age, citizenship, marital status, area of residence, education, employment status and hours worked per week. RESULTS: The cohort included 1 004 655 workers employed in the AFFH sector and 15 269 181 workers in other sectors. During the 6-year follow-up, 559 deaths from suicide (500 men and 59 women) occurred among AFFH workers and 5917 (4935 men and 982 women) among workers in other sectors. The MRR for suicide was 1.36 (95% CI 1.19 to 1.55) among men and 1.18 (95% CI 0.87 to 1.60) among women. The excess risk was remarkably high for casual and fixed-term contract workers (3.01, 95% CI 1.50 to 6.04). CONCLUSIONS: Male workers in AFFH are at high risk of suicide mortality, and casual and fixed-term contract workers are at exceedingly high risk. Our study also suggests a higher risk among single, highly educated and long-hours workers. Female workers in AFFH do not have an appreciably increased risk.

Background: Death certificates are considered the most reliable source of information to compare cause-specific mortality across countries. The aim of the present study was to examine death certificates of persons who tested positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) to (a) quantify the number of deaths directly caused by coronavirus 2019 (COVID-19); (b) estimate the most common complications leading to death; and (c) identify the most common comorbidities. Methods: Death certificates of persons who tested positive for SARS-CoV-2 provided to the National Surveillance system were coded according to the 10th edition of the International Classification of Diseases. Deaths due to COVID-19 were defined as those in which COVID-19 was the underlying cause of death. Complications were defined as those conditions reported as originating from COVID-19, and comorbidities were conditions independent of COVID-19. Results: A total of 5311 death certificates of persons dying in March through May 2020 were analysed (16.7% of total deaths). COVID-19 was the underlying cause of death in 88% of cases. Pneumonia and respiratory failure were the most common complications, being identified in 78% and 54% of certificates, respectively. Other complications, including shock, respiratory distress and pulmonary oedema, and heart complications demonstrated a low prevalence, but they were more commonly observed in the 30-59 years age group. Comorbidities were reported in 72% of certificates, with little variation by age and gender. The most common comorbidities were hypertensive heart disease, diabetes, ischaemic heart disease, and neoplasms. Neoplasms and obesity were the main comorbidities among younger people. Discussion: In most persons dying after testing positive for SARS-CoV-2, COVID-19 was the cause directly leading to death. In a large proportion of death certificates, no comorbidities were reported, suggesting that this condition can be fatal in healthy persons. Respiratory complications were common, but non-respiratory complications were also observed.
