An assessment of US and Canadian smoking reduction objectives for the year 2000
1Graduate School of Management, University of California, Irvine 92697, USA. cpechman@uci.edu
Objectives:
This study assessed whether US and Canadian smoking reduction objectives for the year 2000 are attainable. The United States seeks to cut smoking in its population to 15%; the Canadian goal is 24%.
Methods:
Smoking data were obtained for the United States (1974-1994) and Canada (1970-1995) for the overall populations and several age-sex subpopulations. Analyses estimated trends, future prevalences, and the likelihood of goal attainment. Structural time-series models were used because of their ability to fit a variety of trends.
Results:
The findings indicate that smoking has been declining steadily since the 1970s, by approximately 0.7 percentage points a year, in both countries. Extrapolating these trends to the year 2000, the US prevalence will be 21% and the Canadian prevalence 24%.
Conclusions:
If the current trends continue, the Canadian goal seems attainable, but the US goal does not. The US goal is reachable only for 65-to 80-year-olds, who already have low smoking prevalences. It appears that both countries must increase their commitment to population-based tobacco control.
