Homicide in Chile: Trends 2000-2012

The Epidemiology of Violent Deaths in Chile between 2001 and 2018: Prevalence, Trends, and Correlates

BACKGROUND

Despite its enormous health and social burden, there are limited published studies describing the epidemiology of violent deaths in Chile. We described violent mortality rate trends in Chile between 2001 and 2018, its current spatial distribution and ecological level correlates.

METHODS

A population-based study using publicly accessible data. We calculated age-adjusted mortality rates per 100,000 persons for sex, age, intention, and mechanism of death. Next, we used linear regression to estimate time trends for sex and intention. We then employed hierarchical Poisson analyses to model the spatial distribution across 345 municipalities and the influence of six ecological level variables.

RESULTS

The average rate of violent death in Chile between 2001 and 2018 was 15.9 per 100,000 people, with the majority (70.3%) of these attributed to suicide. Suffocation was the most common mechanism of death for suicide (82.3%) and cut/pierce for homicide (43.1%), followed by firearm (33.2%). Violent deaths are trending downward in Chile across all categories except suicides by women, which have remained stable. Poverty rates and urban population were positively associated with violent mortality rates.

CONCLUSIONS

Although violence-related deaths seem to be decreasing, disparities across gender, age group, and geographic location may have continuing effects on mortality rates.

Characteristics of unnatural deaths in Tierra del Fuego, Argentina: A 10-year study (2008-2017)

A retrospective review was undertaken of 287 unnatural deaths undergoing medicolegal investigation over a 10-year period from January 2008 to December 2017 in Rio Grande, Tierra del Fuego, Argentina. There were 219 males and 68 females, age range 7 months to 88 years (average 38.4 years). The 135 accidental deaths (47%) were due mainly to vehicle crashes ( N = 62) and carbon monoxide toxicity from fires ( N = 31). The 115 cases of suicides (40.1%) were predominantly due to hanging ( N = 75) and gunshot wounds ( N = 20). The 37 cases of homicide (12.9%) were mainly due to stabbing/sharp force injury ( N = 20) and blunt force trauma ( N = 9). Carbon monoxide toxicity from faulty heating accounted for a substantial percentage (8.1%) of the accidental deaths. Firearm homicides and suicides related to drug toxicity and carbon monoxide inhalation were relatively uncommon medicolegal cases in this centre.

Underage victims and perpetrators of murder in Italy: 2007-2015

From the epidemiological and criminological points of view, murders committed by minors, including both victims and perpetrators, differ from those observed in adults. Analysis of trends and characteristics of murders at national level could provide useful information to assess the phenomenon and address political and social choices aiming at preventing violence involving children and adolescents. This study focuses on the trends of murders in Italy during the period 2007-2015 and compares the data with those for other age groups. Data on murders regarding trends, gender, age and ethnic group from the Italian Institute of Statistics were analysed by chi-square with odds ratio and linear regression. Results show that, after standardization, murders involving minors as victims and perpetrators were less frequent with respect to data observed in all age groups. Trend analysis showed that murders involving minors remained stable in the period considered, but the stability of the rate of murders of minors was in contrast with reduced rates in other age groups. Among minors, males aged 14-17 are at higher risk of being the perpetrators and victims of homicide. The rate of perpetrators and victims among foreign-born minors was higher than that among the native-born. Further studies are needed to determine risk factors associated with these results and to propose preventive strategies through appropriate policies and interventions.

Transport accident mortality in Chile: trends from 2000 to 2012

Abstract The aim of this study is to describe the trends of transport accident mortality in Chile from 2000 to 2012 by year, geographic distribution, gender, age group, and type of accident. Population-based study. Data for transport accident mortality in Chile between 2000 and 2012 were used. The crude and adjusted per region transport accident mortality rates were calculated per 100,000 inhabitants. The annual percentage change (APC) of the rates and relative risks (RR) were calculated. The average transport accident mortality rate (TAMR) in Chile (2000-2012) was 12.2. The rates were greater in men (19.7) than in women (4.8), with a RR of 4.1. The rates were higher in the country's southern zone (15.9), increasing in recent years in the southern zone, with a significant positive APC in the northern and central zones. The Maule region had the highest rate (21.1), although Coquimbo was the region with the most significant APC (2.2%). The highest rate (20.3) was verified in the 25-40 age group. The highest rate (14.3) was recorded in 2008. The most frequent type of accident was pedestrian. In general the APC trends of the rates are increasing significantly. This, added to rapid annual automotive growth, will only exacerbate mortality due to transport accidents.
