Abstract: | The objective of this study was to calculate the prevalence of multiple exposures to four modifiable risk factors (smoking, alcohol, physical inactivity and overweight) and to establish whether there are more Canadians with multiple risk factor exposures than those with singular ones. Weighted estimates of the prevalence of mutually exclusive risk factor clusters were calculated according to the Canadian Community Health Survey, Cycle 1.1 (2000). Confidence limits were estimated by bootstrap techniques. Findings indicate that 21.0 percent of Canadians have no risk factor exposures, 53.5 percent are physically inactive, 21.5 percent currently smoke, 44.8 percent are overweight, and 6.0 percent are high-risk drinkers. Compared to females, males are less physically inactive but more likely to smoke, have high alcohol intake and be overweight, across all age groups. At least one risk factor was present in 79.0 percent of Canadians and 39.0 percent have at least two coexistent exposures. The distribution of risk factor prevalences differed significantly by age, most peaking among those between age 35 and 64, with the exception of physical inactivity. Those who smoke and are physically inactive account for the highest proportion of the population with two or more coexistent risk factors. Canadians who are free of the four risk factors for chronic disease examined in this paper constitute the minority. Future studies are recommended to examine other risk factors, as well as interactions of multiple exposures in association with chronic disease. |
