A study of injuries during life in three male populations.

In a population study of samples of 60-, 50-, and 30-year-old men, information about injuries suffered during life was obtained by personal interview. Included were head injuries with unconsciousness, and injuries which had caused restricted activity for more than one day or had caused medical attendance. The interview technique was the only way to cover all these injuries. Possible biases are discussed. The results indicated that the young men tended to report a higher incidence of injuries, to suffer their first injury at an earlier age and to attend medical services to a larger extent than the older men. An incidence peak in adolescence was reported in all three cohorts. Accidents with multiple injuries were more common in higher ages in all cohorts. Falls, blows, and impacts, cutting and piercing agents, and traffic accidents were the most common causes of injuries in all cohorts.
