title: [Who is the victim and who the offender in intimate partner physical violence? An epidemiological study in seven cities of Peru].
abstract: OBJECTIVE
  To identify factors associated to the probability of being the aggressor or the victim in cases of intimate partner physical violence.
  
  
  METHODS
  A secondary data analysis was performed to an epidemiological survey done in seven cities in Peru (Lima, Arequipa, Huamanga, Trujillo, Cuzco, Callao and Maynas). 6399 men and women participated, of whom 3909 participants declared living together with an intimate partner at the time of the interview. Univariate and multivariate logistic regression models were used to identify associated factors to the roles of victim or aggressor.
  
  
  RESULTS
  The likelihood of being aggressor or victim in cases of intimate partner physical violence was independent of sex (p<0,01) and the couple's time living together. Factors associated to a higher probability of both roles included a history of exposure to physical violence during childhood, having a favorable attitude towards violence, heavy alcohol drinking, and being younger than 45 years, as well as having a monthly family income of less than 750 USD or an educational attainment of less than complete tertiary school. Geographically, Cusco was the city where it was most likely to find an aggressor or a victim of intimate partner physical violence. Most of these associations obtained p-values of less than 0.001.
  
  
  CONCLUSIONS
  In cases of intimate partner physical violence, the pattern of predictors is similar in both roles, i.e., aggressor and victim. Sex and the couple's span of time living together did not predict any of both roles.
