Prevalence of and Risk Factors for Self‐Reported Chronic Bronchitis in a Canadian Population: The Canadian Community Health Survey, 2007 To 2008

“…Cigarette smoke causes an inflammatory reaction in bronchial or alveolar mucosa, and increased sensitivity to irritants. Previous studies have reported a higher prevalence of CB in smokers compared with nonsmokers (21)(22)(23)(24)(25)(26)(27)(28)(29). Our results also supported these findings and showed that in all regions, current smokers had a higher prevalence of self-reported CB compared with never smokers.…”

“…Furthermore, these prevalences varied according to location of residence. Numerous studies have demonstrated a relationship between socioeconomic status and CB (18,21,(29)(30)(31)(32)(33)(34). Educational attainment is among the key indicators of socioeconomic status and our results demonstrated that less than high school-educated participants were significantly more likely to self-report CB in the Ontario, Quebec, British Colombia and Atlantic regions.…”
