摘要:We used the previously validated IMPACT coronary heart disease (CHD) mortality model to estimate the CHD deaths attributable to reductions in smoking prevalence following the introduction of the Massachusetts Tobacco Control Program (MTCP) in 1993. A 29% and 31% decline in smoking prevalence and CHD mortality rates occurred, respectively (from 1993 to 2003). A total of 425 fewer CHD deaths, which generated approximately 3365 extra life-years, were attributable to decreased smoking prevalence. With these results in mind, a comprehensive tobacco control program should be sustained and supported. Monitoring and evaluating of comprehensive tobacco control programs such as the Massachusetts Tobacco Control Program (MTCP) can provide valuable data and evidence to support the health effects of reduced tobacco use on a population basis. The MTCP, funded by a 1992 ballot initiative that launched a statewide program through a special cigarette tax, has had a dramatic effect on adult smoking prevalence since the program’s introduction in January 1993. 1 Therefore, the population health impact of the MTCP on reducing coronary heart disease (CHD) death rates is an important issue for which we provide new quantitative analysis.
