Ambient temperature and deaths from homicide in Brazil from 2010-2019: a nationwide space-time-stratified case-crossover study.

ABSTRACT: Previous evidence suggests a positive association between temperature and homicide, but the association was less clear in Brazil where homicide is one of the leading causes of death. This study aimed to quantify the association between ambient daily temperature and homicides in Brazil with potential lag effects and to quantify the temperature-attributed fractions of homicides in Brazil. A space-time-stratified case-crossover design with distributed lag models was used to evaluate the temperature-homicide association from January 1, 2010, to December 31, 2019, in Brazil. The odds ratios, attributable fractions, and their CIs were calculated. Overall, every 5°C increase in daily mean temperature was associated with a 10.6% (OR = 1.106, 95% CI: 1.085-1.127) increase in homicidal deaths at lag
