Compliance with the smoking ban in enclosed, semiopen and open areas of workplaces and public places in Chile

A Comprehensive Review on the Impacts of Smoking on the Health of an Individual

Long-term smoking for several years has been known to cause severe ailments in humans from the beginning. Even after knowing that this dangerous addiction is a life-threatening deal, still, ironically, the prevalence of smoking is more or less not getting reduced to a desirable extent. Those who smoke are becoming miserable because of their habit of smoking. Still, on the other hand, due to passive smoking, many more innocent lives are also adversely affected for no fault. This aspect of smoking, i.e., passive or second-hand smoking, is a fearful complication of smoking which is seldom seen with other modes of addiction. Time and again, numerous researches have highlighted the adverse effects of smoking on the human body and the interference it does bring in one's life. Smoking contributes to the deterioration of many preexisting ailments and depletes many valuable aspects of the human body. Smoking thus has a devastating effect on almost all of the tissues of our body and thus exerts its effect on nearly all the major organs. This review article is made by analysing various findings from many researches conducted across the globe by having a thorough search of Pubmed database, which in turn is the main methodology of the article. This review article aims to provide a simple and subtle understanding of the ill effects of smoking on the human body by serving the readers with a readymade platter of comprehensive knowledge about smoking coupled with efforts to eliminate the associated myths.

Exposure of 4-year to 24-year olds to tobacco imagery on prime-time Chilean television

INTRODUCTION

The extent of the population's exposure to tobacco imagery across all genres of regular TV programming and the contribution of each of these genres is unknown, except for UK broadcast channels. The objective of this study is to estimate the exposure of young people to tobacco imagery on Chilean prime-time television and the programme source contributing to such exposure.

METHODS

Programmes aired during 3 weeks in 2019 from the 15 highest audience channels in Chile were content-analysed for the occurrence of tobacco categorised as actual use, implied use, tobacco paraphernalia, tobacco brand appearances and whether they violated Chilean smoke-free law for each 1 min interval (92 639). The exposure of young people to tobacco content was estimated using media viewership figures.

RESULTS

Young people received 29, 11 and 4 million tobacco impressions of any type, explicit use and smoke-free violation, respectively, at a rate of 21.8, 8.0 and 2.1 thousand impressions per hour of TV viewing. The main sources of exposure to tobacco impressions were feature films and animated productions, which were almost entirely non-Chilean. Finally, young people were exposed to tobacco brand impressions primarily through films, effectively circumventing the advertising ban in Chile.

DISCUSSION

Television programming is a source of significant youth exposure to tobacco imagery, including branding impressions. To conform to the WHO FCTC, Chile should prohibit tobacco branding in any TV programme and require strong anti-tobacco advertisements prior to any TV programme portraying tobacco.

Compliance with the smoke-free policy in hospitals in Spain: the patients' perspective

OBJECTIVE

To explore compliance with the smoke-free policy in hospitals in Catalonia, Spain, by exploring inpatients' perceptions.

METHODS

We conducted a cross-sectional study of a random sample of 1047 inpatients from 13 public hospitals. We collected data about: (a) type of information about the smoke-free policy provided by the hospital, (b) patients' knowledge about the policy, (c) general appreciation of the compliance with the policy, and (d) specific appreciation of such compliance by noticing any sign of tobacco consumption. We described the data by several patients' and hospitals' characteristics and assessed their association with the perceived noncompliance using prevalence ratios (PR) and their 95% confidence intervals (CIs).

RESULTS

Few patients were informed about the smoke-free policy (4.8% orally, 6.1% in writing, and 55.6% through sign postings). About 64% were aware of the regulation and 73.5% believed that it was properly obeyed. While 0.7% had never or rarely observed smoking indoors, 36.2% had seen someone smoking outdoors sometimes or many times. Signs of tobacco consumption were observed indoors and outdoors. Factors associated with the perception of noncompliance were: being less than 45 years old versus being more than 64 years old (adjusted PR, 2.33; 95% CI, 1.09-4.98) and currently smoking versus have never smoked (adjusted PR, 1.84; 95% CI, 1.02-3.34).

CONCLUSION

Compliance with the smoke-free policy in hospitals according to the patients' view is notable, although several infringements were reported, mainly outdoors. The smoke-free policy in hospitals should be reinforced by prompting continuous awareness campaigns and the exemplary role of hospital workers.

Smoking Ban Law in Chile: Impact in Newborns' Birth Weight by Women's Age Groups and by City Population Density

Objectives: We examined the short-term impact of the Smoking Ban Law (SBL) enacted in Chile in 2013 on low birth weight (LBW) rates in cities and its differential effects by different maternal age groups and city density. Methods: We included 885,880 live births from 21 Chilean cities of ≥100,000 inhabitants. We examined the smoking and LBW prevalence distribution before and after the SBL. Through Poisson mixed effect models, we determined whether a meaningful change in LBW rate occurred after SBL implementation in the whole sample and stratified by city population density and maternal age group. Results: LBW prevalence remained stable before and after the SBL implementation (6.1% and 6.3%, respectively), while women's smoking prevalence had a relative reduction of 25.9% (p < 0.00001). No significant changes in LBW rate occurred after the implementation of SBL in the total sample or stratified by city density tertiles or maternal age groups. Conclusion: SBL implementation did not show short-term impact on LBW rate in Chile. Further studies need to examine long-term impact of SBL on low birthweight.

Smoke-free spaces: a decade of progress, a need for more?

Adoption of smoke-free measures has been one of the central elements of tobacco control activity over the past 30 years. The past decade has seen an increasing number of countries and proportion of the global population covered by smoke-free policies to some extent. Despite reductions in global smoking prevalence, population growth means that the number of non-smokers exposed to the harms caused by secondhand smoke remains high. Smoke-free policy measures have been shown to be useful in protecting non-smokers from secondhand smoke, and can additionally increase cessation and reduce smoking initiation. Policies tend to be aimed primarily at enclosed public or workplace settings with very few countries attempting to control exposure in private or semiprivate spaces such as homes and cars, and, as a result, children may be benefiting less from smoke-free measures than adults. Compliance with legislation also varies by country and there is a need for education and empowerment together with guidance and changing social norms to help deliver the full benefits that smoke-free spaces can bring. Restrictions and policies on use of electronic cigarettes (e-cigarettes) in smoke-free settings require more research to determine the benefits and implications of bystanders' exposure to secondhand e-cigarette aerosol, dual use and smoking cessation.

Association between Lifetime Tobacco Use and Alcohol Consumption Trajectories and Cardiovascular and Chronic Respiratory Diseases among Older People

Background: We identify representative types of simultaneous tobacco use and alcohol consumption trajectories across the life course and estimate their association with cardiovascular and chronic respiratory diseases (CVDs and CRDs) among older people in Chile. Methods: We used data from a population-representative, face-to-face and longitudinal-retrospective survey focused on people aged 65–75 (N = 802). To reconstruct trajectory types, we employed weighted multichannel sequence analysis. Then, we estimated their associations with CVDs and CRDs through weighted logistic regression models. Results: Long-term exposure to tobacco use and alcohol consumption across life are associated with the highest CVD and CRD risks. Long-term nonsmokers and nondrinkers do not necessarily show the lowest CVDs and CRDs risks if these patterns are accompanied by health risk factors such as obesity or social disadvantages such as lower educational levels. Additionally, trajectories showing regular consumption in one domain but only in specific periods of life, whether early or late, while maintaining little or no consumption across life in the other domain, lead to lower CVDs or CRDs risks than trajectories indicating permanent consumption in both domains. Conclusions: A policy approach that considers CVDs and CRDs as conditions that strongly depend on previous individual experiences in diverse life domains can contribute to the improved design and evaluation of preventive strategies of tobacco use and alcohol consumption across the life course.

Secondhand smoke exposure assessment in outdoor hospitality venues across 11 European countries

OBJECTIVE

Due to partial or poorly enforced restrictions secondhand tobacco smoke (SHS) is still present in outdoor hospitality venues in many European countries. This study aimed to assess SHS concentrations in outdoor hospitality venues across Europe and identify contextual exposure determinants.

METHODS

Cross-sectional study. We measured airborne nicotine and evidence of tobacco use in terraces of bars, cafeterias, and pubs from 11 European countries in 2017-2018. Sites were selected considering area-level socioeconomic indicators and half were visited during nighttime. We noted the smell of smoke, presence of smokers, cigarette butts, ashtrays, and number of physical covers. Contextual determinants included national smoke-free policies for the hospitality sector, the Tobacco Control Scale score (2016), and the national smoking prevalence (2017-2018). We computed medians and interquartile ranges (IQR) of nicotine concentrations and used multivariate analyses to characterize the exposure determinants.

RESULTS

Nicotine was present in 93.6% of the 220 sites explored. Overall concentrations were 0.85 (IQR:0.30-3.74) μg/m³ and increased during nighttime (1.45 IQR:0.65-4.79 μg/m³), in enclosed venues (2.97 IQR:0.80-5.80 μg/m³), in venues with more than two smokers (2.79 IQR:1.03-6.30 μg/m³), in venues in countries with total indoor smoking bans (1.20 IQR:0.47-4.85 μg/m³), and in venues in countries with higher smoking prevalence (1.32 IQR:0.49-5.34 μg/m³). In multivariate analyses, nicotine concentrations were also positively associated with the observed number of cigarette butts. In venues with more than two smokers, SHS levels did not significantly vary with the venues' degree of enclosure.

CONCLUSIONS

Our results suggest that current restrictions in outdoor hospitality venues across Europe have a limited protective effect and justify the adoption of total smoking bans in outdoor areas of hospitality venues.
