RESUMEN
INTRODUCTION: In Ethiopia, a comprehensive smoke-free law that bans smoking in all public areas has been implemented since 2019. This study aimed to evaluate compliance with these laws by measuring the air quality and conducting covert observations at 154 hospitality venues (HVs) in Addis Ababa. METHODS: Indoor air quality was measured using Dylos air quality monitors during the peak hours of the venues, with concentrations of particulate matter <2.5 microns in diameter (PM2.5) used as a marker of second-hand tobacco smoke. A standardized checklist was used to assess compliance with smoke-free laws during the same peak hours. The average PM2.5 concentrations were classified as good, moderate, unhealthy for sensitive groups, unhealthy for all, or hazardous using the World Health Organization's (WHO) standard air quality index breakpoints. RESULTS: Only 23.6% of the venues complied with all smoke-free laws indicators. Additionally, cigarette and shisha smoking were observed at the HVs. Overall, 63.9% (95% confidence interval: 56-72%) of the HVs had PM2.5 concentrations greater than 15 µg/m3. The presence of more than one cigarette smoker in the venue, observing shisha equipment in the indoor space, and the sale of tobacco products in the indoor space were significantly associated with higher median PM2.5 concentration levels (p < 0.005). Hazardous level of PM2.5 concentrations-100 times greater than the WHO standard-were recorded at HVs where several people were smoking shisha and cigarettes. CONCLUSIONS: Most HVs had PM2.5 concentrations that exceeded the WHO average air quality standard. Stricter enforcement of smoke-free laws is necessary, particularly for bars and nightclubs/lounges.

BACKGROUND: The prevalence of daily second-hand smoke (SHS) exposure among pregnant non-smoking women and children in Egypt is estimated to be about 50% and 55%, respectively. This study aimed to explore barriers to preventing SHS exposure among pregnant women/children and smoking in the home in Egypt. METHODS: Six focus group discussions with pregnant women/mothers of children residing in urban/rural areas (n=61) were conducted. Data were managed and analyzed using the Framework Method. RESULTS: Sixty one participants aged 18-49 were recruited. They reported being never smokers and SHS exposure for themselves and their children was mainly at home. Pregnant women/mothers had some general knowledge of the dangers of SHS, but their knowledge appeared incomplete. The most commonly reported barriers to preventing SHS exposure/adopting a smoke-free home or workplace were social acceptance of smoking and SHS exposure, masculinity and gender norms of accepting smoking among men as a normative behavior, fear among women of damaging a relationship with family or even divorce, women resigning themselves to SHS exposure, and doctors not being supportive of smoking cessation. The majority of interviewees' families were reported to allow smoking anywhere in the home. Others implemented some measures to prevent SHS; however, these tended to be inconsistently implemented. CONCLUSION: Changing the norm of accepting smoking among men as a normative behavior within Egyptian society and better enforcement of smoke-free policies, will help to protect pregnant women and children from SHS. IMPLICATIONS: This study suggests promising approaches to support the promotion of smoke-free homes (SFH) and prevention of SHS exposure among pregnant women and children in public places in Egypt. Better enforcement of smoke-free policies is needed. Health care professionals (HCPs) should support smoking cessation services in primary health centers (PHCs). SHS policy, practice and research should focus on husbands/fathers as they are the main source of SHS. There is a need for denormalization of SHS exposure in Egyptian society.
RESUMEN
PURPOSE: This study estimated the prevalence of and factors associated with secondhand smoke (SHS) exposure, and assessed attitudes and knowledge about SHS among pregnant women in Cairo, Egypt. METHODS: Pregnant women in the third trimester were recruited to participate in a survey assessing tobacco smoking and SHS exposure during their current pregnancy. Participants were recruited from three antenatal clinics in Cairo, Egypt, from June 2015 to May 2016. We examined differences in sociodemographic characteristics and SHS exposure, attitudes, and knowledge by smoking/SHS status. We used multivariable ordinary least squares regression to examine the association between husbands' smoking and pregnant women's mean daily hours of SHS exposure, adjusting for women's smoking status, age group, education, and urban (vs. suburban/rural) residence. RESULTS: Of two hundred pregnant women aged 16-37 years, about two-thirds (69%) had a husband who smoked tobacco. During their current pregnancy, most women reported being non-smokers (71%), and 38% of non-smokers reported being SHS-exposed. Non-smokers exposed to SHS tended to live in more rural areas and have husbands who smoked in the home. In adjusted analyses, having a husband who smoked was significantly associated with a greater mean number of hours of SHS exposure per day exposed, and this difference was driven by husbands who smoked in the home (p < 0.001). Women in the SHS-exposed group were less likely than other groups to agree that SHS exposure was harmful to their own or their future child's health; however, all groups agreed that SHS was harmful to newborn health. CONCLUSION: Among our sample of pregnant women in Cairo, Egypt, there was a high rate of SHS exposure as well as misconceptions about the safety of SHS exposure to a developing fetus. Our findings suggest a need for targeted education and gender-sensitive messaging about SHS exposure, along with improved enforcement of existing tobacco control policies.
Exposure to secondhand smoke (SHS) remains a major contributor to health problems in pregnant women and their children. Using a survey, this study sought to estimate how many pregnant women in Cairo Metropolitan Area, Egypt, were exposed to SHS and the factors contributing to that exposure, and to assess attitudes towards SHS. During their current pregnancy, 38% of non-smokers reported being exposed to SHS. Non-smokers exposed to SHS tended to live in more rural areas and have husbands who smoked in the home. Having a husband who smoked as well as a husband who smoked in the home was significantly associated with a greater average number of SHS exposure hours per day. Women in the SHS-exposed group were less likely than other groups to agree that SHS exposure was harmful to their own or their future child's health; however, all groups agreed that SHS was harmful to newborn health. Among pregnant women in Cairo, Egypt, there is a high rate of SHS exposureoften driven by SHS exposure in the homeas well as misconceptions about the safety of SHS exposure to a developing fetus. There is a need for targeted education and gender-sensitive messaging about SHS exposure along, with improved enforcement of existing tobacco control policies.

A growing body of research suggests an association between attention deficit hyperactivity disorder (ADHD) and allergic disorders, but little work has been done to explore the role of external factors such as parental smoking at home in the development of comorbid ADHD and allergic disorders. This study aimed to examine the association between allergic diseases and ADHD adjusted for exposure to parental smoking at home in early adolescents. We recruited 250 male (41.7%) and 350 female (58.3%) adolescents (mean [SD] age, 13.29 [0.52] years) via chain-referral sampling. Their ADHD symptoms were assessed by the parent proxy-report version of the Chinese Strengths and Weaknesses of Attention-Deficit/Hyperactivity-symptoms and Normal-behaviours (SWAN) rating scale. Data on the participants' history of clinician-diagnosed allergic diseases, family socio-demographics, and parental smoking habit were collected using a parent-completed questionnaire. Regression analyses were performed to examine the associations of interest. The levels of ADHD symptoms were comparable between allergic and non-allergic participants after controlling for child and family demographics and parental smoking at home. Notably, the risk of probable ADHD was particularly high in participants with food allergies (odd ratio = 4.51, p = 0.011) but not in those with allergic rhinitis after adjusting for parental smoking at home. Our findings suggest that second-hand smoke exposure at home is a potential risk factor underlying the link between ADHD and allergic diseases. Current management guidelines should emphasize the importance of early identification and cessation of tobacco smoke exposure for prevention of comorbidity of ADHD and allergic disorders. Clinical Trial Registration (if any): NA.
RESUMEN
BACKGROUND: European countries differ considerably in the scope and the extent of their policies to protect people from the harms of secondhand smoke exposure. Public opinion may have a substantial influence on several stages of policy development, implementation, and compliance. For this reason, we aimed to evaluate the population level of support for smoke-free policies and its correlates. METHODS: We used data from the TackSHS Survey (2017-2018), a cross-sectional study with representative samples of the general population aged ≥15 years from 12 European countries. We described the proportion of non-smokers' and smokers' support for the implementation of smoke-free legislation in 14 indoor and outdoor settings and the country-level characteristics associated with it. RESULTS: In the total sample (n = 11,902), support for smoke-free legislation were the lowest for restaurants/bar patios (non-smokers = 53.0%; smokers = 29.2%) and the highest for workplaces (non-smokers = 78.5%; smokers = 66.5%). In the country-level analysis, the highest support among non-smokers was for workplaces in Bulgaria (93.1%) and the lowest for restaurants/bars patios in Greece (39.4%). Among smokers, the corresponding estimates were for children's playgrounds in Latvia (88.9%) and for cars in Portugal (21%). For most settings, support for smoke-free legislation was directly related with the countries' prevalence of secondhand smoke presence and reported smoking in each setting. DISCUSSION: Our results show that the majority of European adults (including a large proportion of smokers) are supportive of implementing smoke-free legislation in indoor settings and extending it to selected outdoor settings. Such expressive support can be seen as an opportunity to advance legislation and protect the European population from secondhand smoke exposure.

Objective To investigate the relationship between second-hand smoke exposure and lung cancer death trend in Huizhou area. Methods The corresponding records of lung cancer in the tumor registration system in Huizhou area from January 2019 to December 2019 were collected to investigate the subjects' second-hand smoke exposure. Linear regression model was used to analyze the correlation between the mortality of lung cancer patients and the second-hand smoke exposure rate. Logistic regression model was used to analyze the correlation between second-hand smoke exposure and death of lung cancer patients. Results In 2019, the mortality rate of lung cancer patients in Huizhou was the highest in the third quarter, and the second-hand smoke exposure rate of lung cancer patients was also the highest in the third quarter. The mortality rate of lung cancer patients in Huizhou was significantly positively correlated with the second-hand smoke exposure rate (r2 = 0.985 9, P<0.05). The second-hand smoke exposure rate, second-hand smoke exposure concentration, and the extent of second-hand smoke environmental enclosure of dead cancer patients were significantly higher than those of lung cancer patients in the survival group, and the difference was statistically significant (P<0.05). The second-hand smoke exposure, second-hand smoke concentration and the extent of the enclosure of second-hand smoke environment were independent risk factors influencing the death of lung cancer patients (P<0.05). Conclusion The trend of lung cancer deaths in Huizhou in 2019 was consistent with the prevalence of second-hand smoke exposure. The second-hand smoke exposure is an important factor for lung cancer deaths.
RESUMEN
OBJECTIVES: Prisons in Scotland were one of the few workplaces exempt from the 2006 comprehensive smoking ban in indoor public places, excluding the prison workforce from the health benefits of smokefree workplaces. The November 2018 introduction of comprehensive restrictions on smoking in Scottish prisons aimed to protect prison staff and people in custody from the harmful impacts of second-hand smoke (SHS) exposure. This study presents SHS exposure data gathered after smokefree policy implementation and compares these with data gathered during and before policy development. METHODS: Dylos DC1700 monitors were used to measure concentrations of fine particulate matter (PM2.5) derived from SHS across Scotland's 15 prisons. Six days of fixed-site monitoring (09.00 22 May 2019 to 09.00 28 May 2019) were conducted in residential halls in each prison 6 months post-smokefree policy implementation. Prison staff task-based measurements were conducted to assess concentrations of SHS in various locations (e.g. gyms and workshops) and during specific activities (e.g. cell searches, maintenance, and meal service). Utilizing the fixed-site monitoring data, typical daily PM2.5 exposure profiles were constructed for the prison service and time-weighted average (TWA) exposure concentrations were estimated for the typical shift patterns of residential staff pre- and post-smokefree policy implementation. Staff perceptions of changes to SHS exposure were assessed using online surveys. RESULTS: Analysis of both fixed-site and mobile task-based PM2.5 measurements showed the smokefree policy implementation was successful in reducing SHS exposures across the Scottish prison estate. Measured PM2.5 in residential halls declined markedly; median fixed-site concentrations reduced by more than 91% compared with measures in 2016 before policy announcement. The changes in the TWA concentrations across shifts (over 90% decrease across all shifts) and task-based measurements (89% average decrease for high-exposure tasks) provide evidence that prison staff exposure to SHS has significantly reduced. Following smokefree policy implementation, the majority of staff reported no longer being exposed to SHS at work. CONCLUSIONS: To our knowledge, this is the first comprehensive international study to objectively measure SHS levels before, during, and after implementation of a smokefree policy across a country's prison system. The findings confirm that such a policy change can be successfully implemented to eliminate occupational exposures to SHS. The results are highly relevant for other jurisdictions considering changes to prison smoking legislation.

BACKGROUND: Pregnant women's exposure to secondhand smoking (SHS) is associated with detrimental effects on the pregnancy outcomes. OBJECTIVES: The objective of the study was to compare the effectiveness of face-to-face counseling, based on health belief model (HBM), combined with a written educational pamphlet, and health education using written pamphlet only, in improving pregnant women's perception, behavior to avoid SHS and change in exposure to SHS. METHODS: A randomized controlled trial was conducted in 2016. The intervention group received face-to-face health counseling on SHS, while the control group received only written educational pamphlets. Outcomes were the change in the perception of mother on the four constructs of the HBM and the change in mothers' behavior of avoidance of SHS exposure. RESULTS: A total of 100 women were recruited for the study, of whom 93 (47 intervention and 46 control) women completed the study. All women identified their spouse as a source of SHS exposure. Following the intervention, the intervention group had significantly higher scores in the perception of susceptibility (21 ± 4 vs. 16 ± 7, P < 0.01) and severity (15 ± 3 vs. 12 ± 4, P < 0.01) and reduced perception scores of barriers to avoid SHS exposure (11 ± 4 vs. 9 ± 5, P = 0.03), compared to the control group. However, there was an insignificant change in the exposure to SHS after the intervention in both the groups; where 25 (53.2%) women in the intervention group and 31 (67.4%) in the control group (P = 0.16), continued to being exposed to SHS. CONCLUSION: Counselling of pregnant women, based on HBM, has insignificant effect in reducing their exposure to SHS; however it is effective in improving their knowledge and perception about SHS exposure.

BACKGROUND: Dental caries in primary teeth is a serious oral health concern among children. It can lead to detrimental impacts on a child's growth, development, and quality of life. Therefore, this cross-sectional study aimed to examine the prevalence of dental caries and its associations with nutritional status, sugar and second-hand smoke exposure among pre-schoolers. METHODS: A total of 26 pre-schools in Seremban, Malaysia were randomly selected using the probability proportional to size sampling. Dental examination was performed by a dentist to record the number of decayed teeth (dt). Weight and height of the pre-schoolers were measured. The mother-administered questionnaire was used to gather information pertaining to the sociodemographic characteristics and second-hand smoke exposure. Total sugar exposure was calculated from a 3-day food record. RESULTS: Among the 396 participating pre-schoolers, 63.4% of them had at least one untreated caries, with a mean ± SD dt score of 3.56 ± 4.57. Negative binomial regression analysis revealed that being a boy (adjusted mean ratio = 1.42, 95% CI = 0.005-0.698, p = 0.047), exposed to second-hand smoke (adjusted mean ratio = 1.67, 95% CI = 0.168-0.857, p = 0.004) and those who had more than 6 times of daily total sugar exposure (adjusted mean ratio = 1.93, 95% CI = 0.138-0.857, p = 0.013) were significantly associated with dental caries among pre-schoolers. CONCLUSION: A high prevalence of dental caries was reported in this study. This study highlights the need to reduce exposure to second-hand smoke and practice healthy eating behaviours in reducing the risk of dental caries among pre-schoolers.

OBJECTIVE: To investigate the association between second-hand smoke (SHS) exposure and sleep disturbances by systematically reviewing the literature base and to quantify this association by conducting a meta-analysis. METHOD: We did a systematic search of five databases- PubMed, Embase, CINAHL Plus, Web of Science - Core Collection, and Google Scholar. The primary outcomes were short sleep duration (SSD), poor sleep quality (PSQ), and excessive daytime sleepiness (EDS). RESULT: Our systematic search yielded a total of 1623 studies. However, 12 studies qualified for qualitative synthesis and 11 studies (12 surveys) with adequate information were included in the meta-analysis involving 730,808 participants. All the studies were cross-sectional. We found an association between SHS exposure and SSD [pooled OR: 1.20 (95% CI, 1.09-1.33; p = 0.0003; I2= 68%), N = 7]; EDS [pooled OR: 1.07 (95% CI, 1.01-1.13; p = 0.02; I2 = 0%), N = 4]; and PSQ [pooled OR: 1.12 (95% CI, 1.01-1.23; p = 0.03; I2 = 79%), N = 10]. Subgroup analyses suggest significant association between SHS exposure and PSQ among adolescents. However, no such association was observed among adults. In addition, no significant association was observed between PSQ and SHS exposure when biomarker was used to identify SHS exposure. CONCLUSION: This study is the first systematic review and meta-analysis to examine the association between SHS exposure and sleep outcomes. Self-reported exposure to SHS is positively associated with SSD, EDS, and PSQ, although the effects are modest. Further studies with robust methodology to ascertain exposure information are warranted to further elucidate the relationship between SHS exposure and sleep disturbances.

BACKGROUND: Second-hand smoke exposure has been associated with poor mental health. However, among Japanese adults, little is known about the association between second-hand smoking and depressive symptoms. We examined this association in a cross-sectional study among a Japanese general adult population sample. METHODS: Japanese adults were recruited from the Japan Multi-Institutional Collaborative Cohort Study in the Okazaki area between 2012 and 2017. Second-hand smoke exposure and smoking status were assessed using a self-administered questionnaire. Based on their frequency of exposure to second-hand smoke, non-smokers and smokers were categorized as "almost never," "sometimes," and "almost every day". Depressive symptoms were defined by a Kessler 6 score ≥5 points. We performed a multivariable Poisson regression analysis to obtain adjusted prevalence ratios (PRs) and 95% confidence intervals (CIs) for depressive symptoms. RESULTS: Overall, 5,121 participants (4,547 non-smokers and 574 smokers) were included whose mean age was 63.6 (standard deviation [SD], 10.3) years for non-smokers and 59.33 (SD, 10.2) years for smokers. The association between second-hand smoking and depressive symptoms was significant among non-smokers, but not among smokers. Among non-smokers, PRs compared with "almost never" were 1.25 (95% CI, 1.09-1.42) for "sometimes" and 1.41 (95% CI, 1.09-1.84) for "almost every day" (P for trend <0.001); among smokers, PRs compared with "almost never" were 1.30 (95% CI, 0.82-2.06) for "sometimes" and 1.44 (95% CI, 0.90-2.33) for "almost every day" (P for trend = 0.144). CONCLUSIONS: Second-hand smoking and depressive symptoms were associated among non-smokers. Our findings indicate the importance of tobacco smoke control for mental health.

Childhood environmental tobacco smoke (ETS) exposure is a risk factor for adverse health outcomes and may disproportionately burden lower socioeconomic status groups, exacerbating health disparities. We explored associations of demographic factors, stressful life events, and chemical co-exposures, with cotinine levels, among girls in the CYGNET Study. Data were collected from families of girls aged 6-8 years old in Northern California, through clinic exams, questionnaires and biospecimens (n = 421). Linear regression and factor analysis were conducted to explore predictors of urinary cotinine and co-exposure body burdens, respectively. In unadjusted models, geometric mean cotinine concentrations were higher among Black (0.59 ug/g creatinine) than non-Hispanic white (0.27), Asian (0.32), or Hispanic (0.34) participants. Following adjustment, living in a rented home, lower primary caregiver education, and lack of two biologic parents in the home were associated with higher cotinine concentrations. Girls who experienced parental separation or unemployment in the family had higher unadjusted cotinine concentrations. Higher cotinine was also associated with higher polybrominated diphenyl ether and metals concentrations. Our findings have environmental justice implications as Black and socio-economically disadvantaged young girls experienced higher ETS exposure, also associated with higher exposure to other chemicals. Efforts to reduce ETS and co-exposures should account for other disparity-related factors.

BACKGROUND: The objective of this study is to evaluate the risk of exposure to second hand smoke (SHS) during working hours by job status and occupation. METHODS: Using the 4th Korean Working Conditions Survey (KWCS), 49,674 respondents who answered the question about SHS were studied. A chi-square test was carried out to determine whether there is a significant different in SHS exposure frequency by general and occupational characteristics and experience of discrimination at work and logistic regression analysis was carried out to identify the risk level of SHS exposure by variables. RESULTS: In this study, we found that male workers in their 40s and 50s, workers employed in workplaces with fewer than 50 employees, daily workers, and people working outdoors had a higher rate of exposure to SHS than the others. The top five occupations with the highest SHS exposure were construction and mining-related occupations, metal core-makers-related trade occupations, wood and furniture, musical instrument, and signboard-related trade occupations, transport and machine-related trade occupations, transport and leisure services occupations. The least five exposed occupations were public and enterprise senior officers, legal and administrative professions, education professionals, and health, social welfare, and religion-related occupations. CONCLUSION: Tobacco smoke is a significant occupational hazard. Smoking ban policy in the workplace can be a very effective way to reduce the SHS exposure rate in the workplace and can be more effective if specifically designed by the job status and various occupations.
RESUMEN
Objective: Urban children with asthma experience high rates of second hand smoke (SHS) exposure. The objective was to examine whether SHS exposure is associated with symptom frequency in children with poorly controlled asthma. Methods: Children were enrolled in a RCT to test the efficacy of an environmental control behavioral intervention versus an attention control group and followed over 12 months. SHS exposure assessed using salivary cotinine measurement. Frequency of child asthma symptoms, healthcare utilization, household smoking and caregiver daily life stress were obtained via caregiver report. Time of enrollment was recorded to assess seasonal factors. Symptom days and nights were the primary outcomes. Multivariable models and odds ratios examined factors that best predicted increased frequency of daytime/nighttime symptoms. Results: Children (n = 222) with a mean age of 6.3 (SD 2.7) years, were primarily male (65%), African American (94%), Medicaid insured (94%), and had poorly controlled asthma (54%). The final multivariable model indicated symptoms in the fall (OR 2.78; 95% CI 1.16, 6.52) and increased caregiver daily life stress (OR 1.13, 95% CI 1.02, 1.25) were significantly associated with increased symptom days when controlling for cotinine level, intervention status, child age and home and car smoking restrictions. Conclusions: There was no impact of SHS exposure on increased symptom frequency. High caregiver daily life stress and symptoms in fall season may place children with asthma at risk for increased day/nighttime symptoms. Close monitoring of symptoms and medication use during the fall season and intervening on caregiver life stress may decrease asthma morbidity in children with poorly controlled asthma.

INTRODUCTION: Health care professionals have an essential role in tobacco control through supporting tobacco control policy actions by promoting smoke-free workplaces and extending tobacco cessation programs. OBJECTIVE: To assess determinants of support for a smoke-free university policy among dental students. MATERIALS AND METHODS: A cross-sectional study of dental students was carried out. Multiple linear regression analyses assessed the determinants of support for a smoke-free policy at the university. RESULTS: A total of 313 students completed the questionnaires. The multivariate model showed a direct relationship of support for a smoke-free university policy with being a nonsmoker [P = 1.95, 95% confidence interval (CI) = 1.37-2.52, p < 0.0001] and having greater knowledge of smoking health hazards (P = 0.26, 95% CI = 0.20-0.30, p < 0.0001). We detected an inverse relationship with being a man (P = -0.49, 95% CI = -2.73 to -0.58, p = 0.03) and with increased willingness to accept second-hand smoke (SHS) exposure score (P = -0.02, 95% CI = -0.04 to -0.01, p < 0.0001). CONCLUSION: This study found that a policy banning smoking would have support from those students who have knowledge of smoking health hazards and those unwilling to accept exposure to SHS.

OBJECTIVES: Although previous studies have suggested an association between second-hand smoke (SHS) exposure and respiratory symptoms, current evidence is inconsistent. Additionally, it remains unclear whether there are frequency-risk relationships between SHS exposure and respiratory symptoms among adolescents. METHODS: A cross-sectional survey was conducted using a stratified cluster sampling method to obtain a representative sample of high school students in Guangzhou, China. The respiratory symptoms were defined as persistent cough or sputum for three consecutive months during the past 12 months. Self-reported SHS exposure was defined as non-smokers' inhalation of the smoke exhaled from smokers on ≥1 day a week in the past 7 days. The univariable and multivariable logistic regression models were fitted to explore the potential frequency-risk relationships between SHS exposure and respiratory symptoms. RESULTS: Among 3575 students, the overall prevalence of SHS exposure was 69.2%, including 49.5% for SHS in public places, 34.5% in homes, 22.7% in indoor campuses and 29.2% in outdoor campuses. There were significantly increased risks of having respiratory symptoms corresponding to SHS exposure in public places (OR=1.60, 95% CI 1.30 to 1.95), in homes (OR=1.53, 95% CI 1.25 to 1.87), in indoor campuses (OR=1.43, 95% CI 1.14 to 1.79) and in outdoor campuses (OR=1.37, 95% CI 1.10 to 1.69) using no exposure as reference. Notably, we observed monotonic frequency-risk relationships between setting-specific(eg, homes, public places and campuses) SHS exposure and respiratory symptoms. CONCLUSION: Our findings suggest that setting-specific SHS exposure is associated with a significant, dose-dependent increase in risk of respiratory symptoms.

INTRODUCTION: Rates of secondhand smoke exposure are currently significantly higher among remote indigenous communities in the top end of Australia. By implementing a 'smoke-free home' rule, secondhand smoke exposure can be reduced. Smoke-free homes encourage quit attempts and improve the health of children. The prevalence of indigenous smoking rates in remote, discrete communities in Australia is elevated compared with their non-indigenous counterparts. The primary aim of this project is to examine the feasibility of conducting a health-driven intervention to encourage community members to make their homes a smoke-free zone. METHODS AND ANALYSIS: This study uses mixed-methods exploratory evaluation design to obtain data from key informants and community householders to assess their willingness to implement a 'smoke-free' rule in their homes. Initial focus groups will provide guidance on intervention content and deliver evaluation procedures and community requirements. A rapid survey will be conducted to ascertain interest from community members in having the project team visit to discuss study objectives further and to have a particle meter (with consent) placed in the house. Focus groups recordings will be transcribed and analysed thematically. Rapid surveys will be analysed using frequency distributions and tabulations of responses. ETHICS AND DISSEMINATION: The National Health and Medical Research Council guidelines on ethical research approaches to indigenous studies will be adhered to. The James Cook University Human Research Ethics Committee has provided ethics approval.

OBJECTIVE: About one-third of the world population is exposed to second hand smoke (SHS) with estimated 600,000 annual deaths. The objective of this article is to determine the exposure of adult Pakistani population to SHS and its association with different demographic variables based on data of Global Adult Tobacco Survey (GATS) conducted in 2014 in Pakistan. METHODS: Secondary analysis of Global Adult Tobacco Survey (GATS) data was done which is a global standard used for systematically monitoring use of both smoked and smokeless tobacco products. GATS Pakistan was a nationally representative survey, conducted in all four provinces among adult males and females aged15 years and above. Using multistage stratified cluster sampling technique a total of 9,856 households were selected and finally 7,831 individuals were enrolled. RESULTS: At homes around 43.3% individuals were exposed to SHS. Univariate analysis revealed that overall males (Odds Ratio, OR: 1.17 CI: 1.04-1.30, p=0.006) and less educated (OR: 1.30, CI: 1.16-1.46, p=0.000) group were at higher odds of being exposed to SHS at homes. Over all exposure to second hand smoke at home was also significantly high among urban residents (p = 0.000). Among nonsmokers age group 15 -35 years (odds ratio, 1.24 CI:1.09-1.04, P=0.01) and less educated group (OR 1.24, CI: 1.09-1.40, p=0.001) were at higher odds of being exposed to SHS at home At indoor workplaces, overall 69.1% and among non-smokers, 65.3% individuals were exposed to SHS. Univariate analysis has shown that less educated group (OR: 1.525, CI: 1.012-2.298, p=0.043) was at higher odds of being exposed to SHS at indoor workplaces. Among various public places exposure of participants to SHS was highest (86%) at restaurants, followed by public transport (74%), marriage halls (65%), universities (46%), health care facilities (35%) and least at schools (20%).. CONCLUSIONS: Less educated males were more exposed to second-hand smoke both at work places and public places; therefore to start with interventions, work places and public places should be a priority as at home results could be confounded by self-smoking as well.
