Summary: | Objective
To explore how much of the coronary heart disease (CHD) mortality
fall in England and Wales can be attributed to changes in smoking prevalence.
Methods
A previously validated cell-based IMPACT CHD mortality model was used to estimate
the deaths prevented or postponed by changes in population smoking prevalence in England
and Wales between 1981 and 2000. CHD mortality statistics and population trends in smoking
were obtained from routine data sources.
Results
In England and Wales between 1981
and 2000, smoking prevalence in adults aged 25-84 decreased from 43% to 28% in men and
from 35% to 24% in women. In men, most of the decrease occurred in those aged over 55.
Smoking prevalence changed little in older women. An estimated 29,460 deaths were prevented
or postponed (DPP) by this population reduction in smoking prevalence. Most of this
benefit was seen in men (86% of the DPPs versus 14% in women).
Conclusions
Large declines
in smoking prevalence accounted for 29,460 fewer CHD deaths in England and Wales
in 2000 compared with 1981. This emphasises the importance of a national strategy with
comprehensive tobacco control programmes to further reduce smoking.
