Análisis temporal de la mortalidad por violencia del compañero íntimo en España / Temporal analysis of mortality due to intimate partner violence in Spain

RESUMEN

Objetivos: Explorar la distribución temporal de la mortalidad por violencia del compañero íntimo (VCI) e identificar posibles agrupamientos temporales en la ocurrencia de muertes por VCI en España. Métodos: Estudio epidemiológico descriptivo basado en las muertes de mujeres por VCI incluidas en el registro de la Federación de Mujeres Separadas y Divorciadas (1998-2003). Se calculó la razón entre las muertes por VCI sucedidas en el mes correspondiente y la mediana de muertes del quinquenio anterior (índice epidémico) desde enero hasta julio de 2003. Se aplicó el modelo de Poisson para contrastar las diferencias observadas por años (1998-2002), por estaciones, por meses y por días de la semana, y se realizó un análisis de regresión simple con la media trimestral de muertes por VCI. Por último, se realizó un análisis de agrupamientos temporales. Resultados: Se observó un índice epidémico (IE) elevado en la mortalidad por VCI en los meses de enero (IE = 1,6), marzo (IE = 1,2), mayo (IE = 1,5), junio (IE = 2) y julio (IE = 2,4) de (..) (AU)

ABSTRACT

Objectives: To analyze the temporal distribution of mortality due to violence by intimate partners (VIP) and to identify possible temporal clusters in women deaths by VIP in Spain. Methods: We performed a descriptive epidemiological study based on the VIP deaths included in the database of the Federation of Divorced and Separated Women (1998-2003). The epidemic index (EI) was calculated as the ratio between the actual number of VIP deaths in a given month from January to July 2003 and the median number in the same month in the five preceding years. A Poisson model was used to analyze the distribution by years (1998-2002), seasons, months, and days. Simple regression analysis was performed with three-monthly means. A temporal cluster analysis was also carried out. Results: In 2003, the EI of VIP mortality was high in January (EI = 1.6), March (EI = 1.2), May (EI = 1.5), June (EI = 2), and July (EI = 2.5). Compared with 1998 and Sundays, respectively, mortality due to VIP was significantly increased in 2001 (relative risk, RR = 1.52; 95% confidence interval [CI], 1.05-2.20) and on Mondays (RR = 1.77; 95%CI, 1.13-2.76). The regression analyses confirmed an increase between the first three-month period of 1998 and the last three-month period of 2001. There were no differences between seasons and months. No temporal clusters of deaths were detected. Conclusions: VIP is currently an increasing epidemic in Spain with no clear temporal pattern. Political and legal efforts to reduce this problem do not seem to be successful (AU)
