[Prevalence of intimate partner violence and related factors in a local city in Japan].

Objectives: This study sought to assess the prevalence of intimate partner violence in a local city of Fukui Prefecture, and whether the subjects' and their partners' demographic characteristics, alcohol use, and violence experienced in the families in which they were raised might be related risk factors.

Methods: We conducted a mail survey of 1,000 subjects aged 20-69 in the city randomly sampled from the population of 45,220 that were stratified by 10 years of age and sex and pulled 100 from each group. Data from two 248 respondents were eligible for analysis. The self-administered questionnaire included items on; 1) whether they were the victims of physical, sexual, social-economic and psychological violence from their intimate partners, and whether they perpetrated violence or not on their partners; 2) demographic characteristics of the subjects and their partners with information on gender, age, occupation, educational background, annual income, the cohabitants, and their alcohol use; 3) the subjects' experience of violence in the family in which they had grown up; exposure to violence between their parents, and being abused by them.

Results: Out of 248 subjects, men accounted for 41.5%. The prevalence rate of any violence experienced from intimate partners was 46.4%, and that of having perpetrated any violence on the partner was 43.1%. Women reported experiencing more "sexual violence" from their partners than did men. In addition, men admitted to more "physical, sexual, and psychological violence" on their partners than women. Those who had themselves been exposed to violence between parents or were victimized by their parents significantly had more experience of violence from their partners and perpetration than those who did not.

Conclusion: The results suggest that questioning about the experience of violence in the family is useful for the early detection of intimate partner violence.
