“…Almost a quarter of Malaysian adults are smokers 14,15 , thus exposure of Malaysian adolescents to SHS is suspected to be substantial. Thus far, there have only been two studies conducted among adolescents in Malaysia.…”

“…Thus far, there have only been two studies conducted among adolescents in Malaysia. One of the studies that was conducted in Peninsular Malaysia involving 2599 students found 56.4% prevalence of SHS exposure 15 . The other study was localized in Kuala Lumpur and Negeri Sembilan and found 66.9% self-reported SHS exposure among 695 primary school students aged 12 years or younger 16 .…”

INTRODUCTIONExposure to secondhand smoke (SHS) has been proven to be detrimental to health. However, there is little information on SHS exposure among Malaysian adolescents. This study aims to assess the magnitude of and factors associated with SHS exposure among school-going adolescents in Malaysia.METHODSWe performed secondary analysis on data from 25461 respondents of the Global School Health Survey in Malaysia. Descriptive analyses and multivariable logistic regression were performed to determine factors associated with SHS exposure.RESULTSRespondents were adolescents of mean age 14.84 (SD=1.45) years, 50.2% of which were male and 49.8% female. Approximately four in ten respondents were exposed to SHS in the past week (41.5%). SHS exposure was significantly higher among respondents who smoked than among non-smokers (85.8% vs 35.7%, p<0.001). The likelihood of exposure to SHS was higher among smoking adolescents (Adjusted OR=1.66, 95% CI: 1.07–2.56) and non-smoking adolescents (AOR=3.15, 95% CI: 1.48–4.71) who had at least one smoking parent/guardian regardless of their own smoking status. Male adolescents had higher risk of SHS exposure compared to their female counterparts (current smoker AOR=1.66, 95% CI: 1.07–2.56; non-smoker AOR=1.50, 95% CI: 1.12–2.00) and increased with age, regardless of their smoking status.CONCLUSIONSOur findings suggest that prevalence of exposure to SHS among school-going adolescents in Malaysia is high. Parents should be advised to stop smoking or abstain from smoking in the presence of their children. Education programmes are recommended to increase awareness on avoidance of SHS as well as smoking cessation interventions for both adolescents and their parents.

“…Exposure to SHS was significantly higher among smokers. We postulated that SHS exposure in the parents'/guardians' car mostly originates from parents/guardians, family members or respondents who smoke, who may be more lenient towards smoking in their car and are unlikely to prohibit guests or household members, or their children, from smoking inside the vehicle 17,18,27 . No positive relationship was observed between age and exposure to SHS in parents'/guardians' cars, after adjusting for the confounding effect of other independent variables.…”

“…Studies on SHS exposure among youth and school-going adolescents have been carried out in Malaysia 17,18 . Ghazali et al 18 reported that more than half of the secondary school-going adolescents were exposed to SHS, and the odds of exposure were higher among male, current smokers and if one of their parents/guardians smoked.…”

INTRODUCTION We investigated the prevalence of children's exposure to secondhand smoke (SHS) in the car of their parents/guardians and the associated factors. METHODS A self-administered validated questionnaire was used to obtain data from the nationally representative samples of school-going adolescents aged 11-19 years in Malaysia. Prevalence rates were computed and chisquared tests and multiple logistic regression were conducted. RESULTS Of the participants, 23.3% reported exposure to SHS at least once in the car of their parents/guardians during the last 7 days before the survey. The prevalence and likelihood of SHS exposure were significantly higher in Malays, descendants of natives of Sabah and Sarawak, schools in rural areas, females, and current smokers. However, age group and knowledge on the harmful effects of SHS were not significant after adjusting for confounding effects. CONCLUSIONS A substantial proportion of school-going adolescents were exposed to secondhand smoke in the car of their parents/guardians. This highlights the need for effective tobacco control measures to include health promotion and smoke-free car regulations to be introduced to prevent severe health hazards and to reduce smoking initiation among non-smoking adolescents.

“…Furthermore, health promotion and smoking cessation programmes that target parents/guardians who smoke can be another strategy to reduce the SHS exposure at home. The studies have shown that SHS exposure was high among youth if their parents/guardians smoke 38,39 . With knowledge, the smoking parent/guardian might be more motivated to smoke outside the house 40 ; in addition, community intervention recruiting the adults should be intensified to promote smoke-free homes and increase the smoking cessation rate, which will ultimately reduce the SHS exposure at home 41 .…”

disease having been a major contributor to mortality since 1980 3 , with a third of diseases due to smoking 4. Several nationwide studies have reported that more than 70% of smokers started to smoke before the age of 18 years; this is in line with other studies conducted ABSTRACT INTRODUCTION Periodic surveys on tobacco use patterns and other aspects of tobacco use among school-going adolescents in Malaysia provide information on the effectiveness of anti-smoking measures implemented. However, such information is limited in Malaysia. We investigated the prevalence of smoking and other related aspects among middle-secondary school students in Malaysia from the years 2003-2016 to fill this gap. METHODS We analyzed data from the Global Youth Tobacco Survey (GYTS) 2003, GYTS 2009, and the Tobacco and Electronic Cigarette Survey among Malaysia Adolescents (TECMA) 2016. The surveys employed multistage sampling to select representative samples of adolescents attending secondary school in Malaysia. Data were collected using a pre-validated self-administered anonymous questionnaire adopted from the GYTS. RESULTS Between 2003 and 2016, major changes occurred in which there were reductions in the prevalence of ever smoking, current smoking, and susceptibility to smoking. Reductions were also observed in exposure to SHS in public places and in the home. The proportion of school-going adolescents who support a ban on smoking in public places increased between 2013 to 2016, and there was a significant reduction in the proportion of respondents that were offered 'free' cigarettes by tobacco company representatives. However, there was no difference in the proportion of adolescents who initiated smoking before the age of 10 years and current smokers seeking advice to quit smoking across the time period. CONCLUSIONS Our study indicates that the smoking policies and measures have been effective in reducing smoking prevalence, secondhand smoke exposure, and access to cigarettes, among school-going adolescents in Malaysia. However, measures to reduce smoking initiation and increase smoking cessation need to be strengthened to reduce the burden of smoking-related diseases in Malaysia in the long-term.
