Abstract

Objective:

to analyze the association between sociodemographic, behavioral and health characteristics and the prevalence of violence against the elderly committed by strangers.

Methods:

cross-sectional study with data from the 2013 National Health Survey on individuals aged 60 years and over; a log-linear Poisson model was used.

Results:

11,143 elderly individuals were included in the study; the prevalence of violence committed by strangers in the 12 months prior to the interview was 1.61 (95%CI 1.28;1.94); in the multivariate analysis, a higher prevalence of violence committed by strangers was observed among elderly individuals aged 60-69 years (PR=2.03; 95%CI 1.02;4.06), with higher education degree compared to those without schooling (RP=4.00; 95%CI 1.89;8.33), residents of the Midwest versus Southeast (PR=2.00; 95%CI 1.16;3.45), and in households not registered in the Family Health Strategy (FHS) (PR=1.57; 95%CI 1.00;2.48).

Conclusion:

sociodemographic characteristics and region of residence were associated with violence against the elderly, committed by strangers.
