MATERIALES Y MÉTODOS:  Estudio observacional, longitudinal y retrospectivo. La tasa de mortalidad ajustada por homicidios en el mundo se estimó mediante el método directo. La asociación se evaluó con regresión de Poisson y univariante.  RESULTADOS: La tasa promedio de homicidios fue de 17.3 por cada 100,000 habitantes. Se observó un incremento significativo en las tasas de homicidios; pasó de 12.31 en el año 2000 a 26.6 por cada 100,000 habitantes en el 2020. El cambio porcentual anual (APC) fue de 5.4 (p &lt; 0.05). El radio promedio de nacimientos M-F del mismo periodo fue de 1.013. Al igual que los homicidios, se observó un aumento significativo en el radio de nacimientos M-F, que pasó de 1.0 en el año 2000 a 1.03 en 2020; APC = 0.24 (p &#8804; 0.01).  CONCLUSIÓN: Se observó una asociación positiva entre los homicidios y el radio de nacimientos masculino-femenino.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract  OBJECTIVE: To evaluate the association between homicide mortality rates and male-to-female birth ratios in Mexico between 2000 and 2020.  METHODS AND MATERIALS: This was an observational, longitudinal, retrospective study. The global homicide-adjusted mortality rate was estimated using the direct method. The global homicide-adjusted mortality rate was estimated using the direct method. The association was evaluated using Poisson regression and univariate analysis.  RESULTS: The average homicide rate was 17.3 per 100,000 inhabitants. A significant increase in homicide rates was observed, rising from 12.31 per 100,000 inhabitants in 2000 to 26.6 in 2020. The annual percentage change (APC) was 5.4% (p &lt; 0.05). The average male-to-female (M:F) birth ratio for the same period was 1.013. Similarly to homicides, a significant increase in the male-to-female birth ratio was observed, rising from 1.0 in 2000 to 1.03 in 2020 (APC = 0.24, p &#8804; 0.01).  CONCLUSION: There was a positive association between homicides and the male-to-female birth ratio.]]></p></abstract>
