[Cardiovascular risk factors among 40-year old men and women in Oslo 1981-1999].
BACKGROUND
Between 1981 and 1991, the City of Oslo offered all its 40-year-old citizens screening for risk factors for cardiovascular disease. We describe changes in risk factors over this period.


METHODS
Between 1981 and 1999, a total of 104,482 men and women born between 1941 and 1959 were invited to undergo screening.


RESULTS
The attendance rate was slightly above 55% in the initial years when the City of Oslo had a centralised administration. After a decentralisation to 25 city districts in 1988, attendance dropped considerably. Body weight, triglycerides, physical inactivity, prevalence of metabolic syndrome and diabetes all increased over the period. The classic risk factors, including total serum cholesterol, high blood pressure and cigarette smoking, were all gradually reduced.


CONCLUSIONS
With regard to the classic risk factors, the findings are consistent with other investigations. The increase in body weight and some other characteristics of the metabolic syndrome are causes for concern.
