BACKGROUND AND METHODS: Changes over time of mortality rates from cutaneous
malignant melanoma (CMM) in Belgium were analysed, based on people (n =
3695) aged 25-84 years, who died of CMM from 1954 to 1992. All data were
collected from the Belgian National Institute of Statistics. For the
log-linear analysis and calculation of the average annual change, only the
data from 1973 to 1992 were considered. RESULTS: The age-adjusted mortality
rates (per 10(5)) for the age group 25-84 years old increased from 0.5 in
1954 to 3.0 in 1992 in men, and from 0.8 in 1954 to 2.2 in 1992 in women.
The average annual percentage change in men (-0.003%) was stable over the
period 1973-1982, and increased to 4.4% over the period 1983-1992. In
women, the average annual increase was 4.6% over the period 1973-1982, and
continued to increase to 6.8% over the period 1983-1992. Log-linear
analysis showed that the change in rates for both men and women was mainly
due to an age-'drift' effect, contrary to the results of the average annual
percentage change in men. CONCLUSION: The risk of dying from CMM increased
in men and women continuously over the whole period, irrespective of birth
cohort. In both men and women, there was approximately a 20% increase in
CMM mortality per 5-year period.
