The purpose of this study is to estimate and compare smoking prevalence over two time periods in a Manitoba First Nation community.
Data fromtwo independent Diabetes Screening Studies in Sandy Bay First Nation, collected in 2002/2003 (n = 482) and 2011/2012 (n = 596),were used. Crude prevalence of current and ever smoking as well as current smoke exposure was estimated. Change over time was tested using a ?² statistic.
The crude prevalence of current smoking was 74.0% (95% confidence interval [CI]: 70.1, 78.0) in 2002/2003 and 80.0% (95% CI: 76.8, 83.2) in 2011/2012. The crude prevalence of ever smoking was 83.0% in 2002/2003 and 91.4% in 2011/2012. The prevalence of both current smoking status and ever smoking were significantly higher in 2011/2012 compared to 2002/2003 (p = 0.020 and p
