Predictors of people's perceptions of second hand smoke exposure as a risk factor for multiple sclerosis

Abstract

BackgroundThere are both environmental and genetic factors which are associated with multiple sclerosis (MS) development. The primary objective of this study was to examine the predictors associated with people's attitudes towards second hand smoke exposure being a risk factor for development of MS. MethodsThe data set was drawn from the Health Canada: Smoking Survey conducted in 2004 and 2005 by Environics Research Group in partnership with Health Canada to survey the public in the province of British Columbia (N = 1468), Newfoundland (N = 1442), Quebec (N = 1404), Ontario (N = 1443) and Saskatchewan (N = 1413). A multilevel mixed effects logistic regression model analysis was carried out in order to determine whether people's perceptions of second hand smoking as a risk factor for MS varied based on the province of residence. ResultsAge, sex, having a household member who smoked inside their home, if respondents were bothered by second hand smoke exposure and smoking status were associated with increased odds of people agreeing to second hand smoke exposure being a risk factor for MS development. The province of residence was also a factor in people's perceptions. ConclusionThe study results could guide in the development of stop second hand smoking campaigns on social media, TV and bus stop shelters and enforcement of stricter policies on smoking areas. This could help raise awareness about the risk of second hand smoking and its detrimental effect on people living with MS.
