Background: It is an undeniable fact that exposure to tobacco smoke from the ambiance poses harmful effects to human health. Although many countries including Malaysia have imposed smoking bans and restrictions in indoor and outdoor public places, yet, to achieve a zero exposure to tobacco smoke from one’s surroundings remains a challenge.
Objective: The objectives of this study were to determine the second-hand smoke (SHS) knowledge and percentage of exposure among adults of rural Pedas, Negeri Sembilan and assess the association between socio-demographics and knowledge of SHS among these adults.
Methods: A cross sectional study with convenient sampling was carried out on 485 adults in Pedas, Negeri Sembilan. The instrument used was a validated questionnaire which was adapted with permission to suit the sample under study. The data collected were analysed with SPSS Statistics for Windows, Version 24.0.
Results: The percentage of SHS exposure among the non-smoking adults in rural Pedas, Negeri Sembilan was high (95.5%). More than 30% of the non-smoking respondents reported a daily exposure to SHS. The adults from this study however have good knowledge of SHS effects on health. A Mann-Whitney U test result revealed that knowledge on SHS scores was significantly higher for the non-smokers than that of smokers (U=17645, p < .001, r=.18). The top three locations identified as the most common places for SHS exposure were restaurants (38.9%), followed by workplace (26.2%) and home (19.4%).
Conclusions: The percentage of SHS exposure among the non-smoking adults of rural Pedas, Negeri Sembilan is high. Although the adults in this study have good knowledge of SHS health consequences, yet they are unavoidably exposed to SHS because smoking still occurs within their home, workplaces and public places. Our findings suggest the need for more comprehensive, assertive and strongly enforced policies to ban smoking in public areas, not only in this community but all across Malaysia.
