Multicentric study of deaths by homicide in Latin American countries

This article is a descriptive epidemiological study of deaths by homicide in Latin American countries (Argentina, Brazil, Colombia and Mexico) from 1990 to 2007. Deaths due to external causes and homicides, as codified in the 9th and 10th revisions of the International Classification of Diseases/ICD, were analyzed considering sex, age and manner of assault. The numbers, ratios and adjusted rates for deaths by homicide are presented. A linear regression model was used to ascertain the trend of homicide rates by age group. During the period, 4,086,216 deaths from external causes and 1,432,971 homicides were registered in these countries. Deaths from external causes rose 54.5% in Argentina but fell in the other countries (37% in Mexico, 31.8% in Colombia, and 8.1% in Brazil). The ratio for deaths by homicide for both sexes was 9.1 in Colombia, 4.4 in Brazil and 1.6 in Mexico, using the Argentinian rates as a benchmark. There were differences in the evolution of homicide rates by age and sex in the countries: the rate rose in Brazil and fell in Colombia for all age groups. The need to prioritize young males in public policies related to health care and prevention is stressed, as well as the need for the region to adopt inclusive policies and broaden and consolidate democracy and the rights of inhabitants.
