Standardised mortality ratios (SMR) may give a good estimate of the relative level of mortality in a local area, and its relation to local social conditions, but if we wish to understand changes in the age distribution of mortality as mortality declines, we need an estimate of the local mortality curve. Such fine detail can be elusive when examining small populations for which the number of people in each age group is small, the number of deaths minuscule, and estimation errors are large. A possible solution to this problem is to estimate age-specific mortality rates simultaneously for all the subunits of a particular country, using the reported number of deaths, by age and sex, for each unit as the input data. The national mortality rates then serve as a model from which local deviations, by age and sex, are estimated, on the basis of overall mortality (SMR) and local social conditions. We demonstrate this approach using data from 87 sub-national units in Belgium to construct local-level life tables, using a multilevel model with the local sex- and age-specific cells as units, nested within sex-age groups and regional units at the second level. The results indicate that life expectancy is closely related to SMR, but the specific shape of the mortality curve, in particular the range over which mid-life mortality is low and the age at which mortality begins to rise into senescence, varies by level of mortality and social conditions.

Background: Suicide is a major cause of premature death in Italy and occurs at different rates in the various regions. Aims: The aim of the present study was to provide a comprehensive overview of suicide in the Italian population aged 15 years and older for the years 1980–2006. Methods: Mortality data were extracted from the Italian Mortality Database. Results: Mortality rates for suicide in Italy reached a peak in 1985 and declined thereafter. The different patterns observed by age and sex indicated that the decrease in the suicide rate in Italy was initially the result of declining rates in those aged 45+ while, from 1997 on, the decrease was attributable principally to a reduction in suicide rates among the younger age groups. It was found that socioeconomic factors underlined major differences in the suicide rate across regions. Conclusions: The present study confirmed that suicide is a multifaceted phenomenon that may be determined by an array of factors. Suicide prevention should, therefore, be targeted to identifiable high-risk sociocultural groups in each country.

Abstract Introduction Despite ongoing improvements in burn care around the world, the burden of burn morbidity and mortality has remined a significant challenge in the Middle East due to ongoing conflicts, economic crises, social disparities, and dangerous living conditions. Here, we examine the epidemiology of burn injuries in the Middle East (ME) relative to socio-demographic index (SDI), age, and sex in order to better define regional hotspots that may benefit most from sustainability and capacity building initiatives. Methods Computational modeling from the 2017 Global Burden of Disease (GBD17) database was used to extrapolate burn data about the nineteen countries that define the ME. Using the GBD17, the yearly incidence, deaths, and Disability-Adjusted Life Years (DALYs) from 1990 to 2017 were defined with respect to age and sex as rates of cases, deaths, and years per 100,000 persons, respectively. Mortality ratio represents the percentage of deaths relative to incident cases. Data from 2017 was spatially mapped using heat-mapping for the region. Results Over 27 years in the ME, an estimated 18,289,496 burns and 308,361 deaths occurred causing 24.5 million DALYs. Burn incidence decreased by 5% globally but only 1% in the ME. Although global incidence continued to decline, most ME countries exhibit steady increases since 2004. Compared to global averages, higher mortality rates (2.8% vs 2.0%) and DALYs (205 vs 152 years) were observed in the Middle East during this time although the respective disparities narrowed by 95% and 42% by 2017. Yemen had the worst death and DALY rates all 27 years with 2 and 2.2 times the ME average, respectively. Sudan had the highest morality ratio (3.7%) for most of the study, twice the ME average (1.8%), followed by Yemen at 3.6%. Sex-specific incidence, deaths, and DALYs in the ME were higher compared to the global cohorts. ME women had the worst rates in all categories. With respect to age, all rates were worse in the ME age groups except in those under 5 years. Conclusions For almost three decades, ME burn incidence, deaths, DALYs, and mortality rates were consistently worse than global average. Despite the already significant differences for burn frequency and severity, especially in women and children, underreporting from countries who lack sufficient registry capabilities likely means that the rates are even worse than predicted.

1. The standard table of mortality most generally used in Britain at the present time for life assurance calculations is the A 1924-29 table, which was derived from the experience of assured lives during the period 1924–29. During the quarter of a century that has elapsed since that time there have been substantial changes in mortality rates and the A 1924-29 table is today out of date. The publication of the A 1924-29 Light table, based upon the experience of certain selected offices whose mortality was lighter than average, has no doubt been helpful in providing a table which goes some way in the direction of the lower mortality rates of today. However, this table suffers from the disadvantage that, while the mortality rates at young ages are not low enough for current experience, at some of the older age-groups the rates are too low, with the consequence that the shape of the mortality curve does not accord with present conditions. The greatest proportionate reductions in mortality since 1924–29 have occurred at the younger ages, and there can be little doubt that a new table is needed to provide offices with an efficient and up-to-date instrument for life assurance calculations.

A new standardised interview for the retrospective assessment of onset and early course of schizophrenia (IRAOS) was used to study the influence of age and sex on time of onset and psychopathology before first admission in 267 schizophrenic patients admitted for the first time. Mean age at onset, according to various operationalised definitions, differed by three to four years between the sexes. The age distribution at the earliest sign of mental disorder showed an early and steep increase until the age of 25 in males, and a delayed and smaller increase in females, with a second peak in women aged 45–79. Schizophrenia began with negative symptoms in 70% of cases, appearing two to six years before admission, and all positive symptoms appearing up to two years before. Both positive and negative symptoms accumulated exponentially. The early course of the disease was similar across age groups, except there was a longer period of negative symptoms before first admission in late-onset schizophrenia in women. The few significant age differences in symptoms were presumably due to general age-dependent reaction patterns like anxiety and depression or the cognitive development of personality, as indicated by an increase in fully elaborated positive symptoms, especially systematised paranoid delusions, with age.

Life table is a table that shows mortality experience of a nation. However, in Malaysia, the information in this table is provided in the five-year age groups (abridged) instead of every one-year age. Hence, this study aims to estimate the one-year age mortality rates from the abridged mortality rates using several interpolation methods. We applied Kostaki method and the Akima spline method to five sets of Malaysian group mortality rates ranging from period of 2012 to 2016. The results were then compared with the one-year mortality rates. We found that the method by Akima is the best method for the Malaysian mortality experience as it gives the least minimum of sum of square errors. The method does not only provide a good fit but also, shows a smooth mortality curve.

To identify secular change in Australian suicide mortality over the period 1907-1998 and to seek possible explanations, a descriptive epidemiological study was conducted. Deaths due to suicide from 1907 to 1998 were identified according to the ICD-9. Trends in overall annual suicide mortality rates for all causes and individual causes were examined using the three-year moving average method, standardised by age and sex. Secular trends for mortality over the study period were examined in various age groups, using linear regression to test the slope. The results indicated that there has been a decline in overall age and sex standardised mortality from suicide over the study period. The death rate dropped from 15.2 per 100,000 in the early century to 13.9 per 100,000 in late century. Despite the overall decline, the female suicide mortality rates increased over the study period. Male suicide mortality rates were significantly higher than female rates over the study period (P<0.0001). Increased suicide rates were observed in the 15-24 and 25-44 year old age groups for both males and females. The group of 65+ year old females also had increased rates. Decreased rates were observed in both the male and female 45-64 year old age group and in the 65+ year old male age group. The three most common suicide methods used by males in 1907 were guns, poisoning and hanging, while for females they were drowning, hanging and poisoning. In 1998 they were changed to hanging, gas and guns for males and hanging, gas and drowning and poisoning (equally third) for females. These trends can be attributed to numerous factors such as economic crisis, world wars, the availability of suicide methods, a person's gender.

Background: Based on civil registries, 26,000 people died from alcoholic cardiomyopathy (ACM) in 2015 globally. In the Global Burden of Disease (GBD) 2017 study, garbage coded deaths were redistributed to ACM, resulting in substantially higher ACM mortality estimates (96,669 deaths, 95% confidence interval: 82,812–97,507). We aimed to explore the gap between civil registry and GBD mortality data, accounting for alcohol exposure as a cause of ACM. Methods: ACM mortality rates were obtained from civil registries and GBD for n = 77 countries. The relationship between registered and estimated mortality rates was assessed by sex and age groups, using Pearson correlation coefficients, in addition to comparing mortality rates with population alcohol exposure—the underlying cause of ACM. Results: Among people aged 65 years or older, civil registry mortality rates of ACM decreased markedly whereas GBD mortality rates increased. The widening gap of registered and estimated mortality rates in the elderly is reflected in a decrease of correlations. The age distribution of alcohol exposure is more consistent with the distribution of civil registry rather than GBD mortality rates. Conclusions: Among older adults, GBD mortality estimates of ACM seem implausible and are inconsistent with alcohol exposure. The garbage code redistribution algorithm should include alcohol exposure for ACM and other alcohol-attributable diseases.

Between 1990 and 2010, chronic obstructive pulmonary disease (COPD) moved from the fourth to third most common cause of death worldwide.Using data from the Global Burden of Disease programme we quantified regional changes in the number of COPD deaths and COPD mortality rates between 1990 and 2010. We estimated the proportion of the change that was attributable to gross national income per capita and an index of cumulative smoking exposure, and quantified the difference in mortality rates attributable to demographic changes.Despite a substantial decrease in COPD mortality rates, COPD deaths fell only slightly, from three million in 1990 to 2.8 million in 2010, because the mean age of the population increased. The number of COPD deaths in 2010 would have risen to 5.2 million if the age- and sex-specific mortality rates had remained constant. Changes in smoking led to only a small increase in age- and sex-specific mortality rates, which were strongly associated with changes in gross national income.The increased burden of COPD mortality was mainly driven by changes in age distribution, but age- and sex-specific rates fell as incomes rose. The rapid response to increasing affluence suggests that changes in COPD mortality are not entirely explained by changes in early life.

Abstract Aim: To examine the magnitude of sex differences in survival from the Coronavirus Disease 2019 (COVID-19) in Europe across age and countries. We hypothesise that men have higher mortality than women at any given age, but that sex differences will decrease with age as only the strongest men survive to older ages.Methods: We used population data from Institut National D’Études Démographiques on cumulative deaths due to COVID-19 from February to June 2020 in 10 European countries: Denmark, Norway, Sweden, The Netherlands, England & Wales, France, Germany, Italy, Spain and Portugal. For each country, we calculated cumulative mortality rates stratified by age and sex and corresponding relative risks for men vs. women.Results: The relative risk of dying from COVID-19 was higher for men than for women in almost all age groups in all countries. The overall relative risk ranged from 1.11 (95% CI 1.01-1.23) in Portugal to 1.54 (95% CI 1.49-1.58) in France. In most countries, sex differences increased until ages 60-69 years, but decreased thereafter with the smallest sex difference at ages 80+.Conclusions: Despite variability in data collection and time coverage among countries, we illustrate an overall similar pattern of sex differences in COVID-19 mortality in Europe.
