[Social network, alcohol drinking habits and injuries caused by violence among women and men in the county of Akershus. Results from anonymous questionnaires among persons aged 40-42 years. 1990-91].

All residents aged 40-42 in Akershus county were invited to screening for cardiovascular risk factors in 1990-91 as part of a prevention programme. Of the 13,607 attendants, 8,960 answered an anonymous questionnaire about social network, drinking habits, and injuries due to violence. Compared with data from the Central Bureau of Statistics, our material included a high percentage of persons with a higher education, a high percentage of married persons, and a low percentage of persons living alone. Results in respect of social network and drinking habits roughly agreed with those of other studies. Of the males, 15.7% had been injured at least once as a result of violence, most often assault and robbery. Of the females, the corresponding percentage was 18.1. Here the dominating forms of violence were maltreatment, threats and sexual assault. Females were more often exposed than males to repeated violence and more often suffered persisting problems as a result of maltreatment. Compared with other studies, we found a high prevalence of injuries from violence among females, suggesting underreporting of experiences of violence by females in studies based on personal interview or the hospitals' injury register.
