Long-term effects of community-based injury prevention on the island of Vaerøy in Norway: a 20-year follow up.
OBJECTIVE
A multifactorial injury prevention programme started in 1981 and ran for about 10 years in an island community in Norway with a population of about 1,000. A study was undertaken to evaluate effects of the programme over a period of 20 years.


METHODS
Injuries were recorded by the one medical doctor on the island for several years during the period 1970-2001. The programme was carried out very intensively from 1981 to 1987. The intensity gradually decreased to a medium level that lasted until about 1994, when it was further reduced to a low level.


RESULTS
The injury incidence rate was reduced from 17.7% in 1980 (n = 188) to 9.7% in 1987 (n = 97) with relative risk reduced to 0.55 (95% CI 0.44-0.70, p < 0.0001). In 2001, an incidence rate of 9.6% was observed (n = 91). An even higher reduction was observed for serious injuries. The age groups 15-24 and 65+ showed the most distinct reductions from 1980 to 2001 while minor reduction was observed in children (0-14 years). The incidence rate of traffic injuries was reduced by 77% in spite of an increase in the number of motor vehicles. Occupational, home, and other injuries were reduced by 38%, 35%, and 49% respectively. The incidence rates were 2.6-3.0 times higher for men than for women through the 20-year observation period.


CONCLUSIONS
This study indicates that a long-lasting multifactorial community-based intervention in a small community with defined aims may lead to a considerable and long-lasting reduction in injuries.
