dSecondhand smoke (SHS) causes premature disease and death in nonsmokers, including heart disease and lung cancer. The Surgeon General has concluded that no risk-free level of SHS exposure exists; the only way to fully protect nonsmokers is to completely eliminate smoking in indoor spaces. Studies have determined that levels of airborne particulate matter in restaurants, bars, and other hospitality venues and levels of SHS exposure among nonsmoking hospitality employees decrease substantially and rapidly after implementation of laws that prohibit smoking in indoor workplaces and public places. To assess changes in indoor SHS exposure in a general population, the New York State Department of Health analyzed data on observations of indoor smoking by respondents to the New York Adult Tobacco Survey (NYATS) and measured levels of cotinine in saliva among nonsmoking NYATS respondents before and after implementation of the 2003 New York state ban on smoking in indoor workplaces and public places. This report describes the results of that analysis, which determined that reports of indoor smoking among restaurant and bar patrons decreased significantly after the law took effect; moreover, saliva cotinine levels in nonsmoking NYATS participants decreased by 47.4% over the same period. These findings suggest that comprehensive smoking bans can reduce SHS exposure among nonsmokers. 相似文献

The authors assessed the impacts of two different smoke-free laws on indoor air quality. They compared the indoor air quality of 10 hospitality venues in Lexington and Louisville, Kentucky, before and after the smoke-free laws went into effect. Real-time measurements of particulate matter with aerodynamic diameter of 2.5 microm or smaller (PM2.5) were made. One Lexington establishment was excluded from the analysis of results because of apparent smoking violation after the law went into effect. The average indoor PM2.5 concentrations in the nine Lexington venues decreased 91 percent, from 199 to 18 microg/m3. The average indoor PM2.5 concentrations in the 10 Louisville venues, however, increased slightly, from 304 to 338 microg/m3. PM2.5 levels in the establishments decreased as numbers of burning cigarettes decreased. While the Louisville partial smoke-free law with exemptions did not reduce indoor air pollution in the selected venues, comprehensive and properly enforced smoke-free laws can be an effective means of reducing indoor air pollution. 相似文献

Exposure to secondhand smoke results in approximately 3,000 lung cancer deaths and 35,000 heart disease deaths in the United States each year. Policies establishing smoke-free environments are the most effective method for reducing exposure to secondhand smoke. Restrictions on where smoking is allowed are also associated with decreased cigarette consumption and possibly with increased cessation rates among workers and the general public. Local laws often impose more stringent smoking restrictions than state laws. Preemptive legislation prohibits communities from enacting laws that are more stringent than or vary from the state law. One of the national health objectives for 2010 is to eliminate laws that preempt stronger tobacco-control laws (objective no. 27-19). In 1999, CDC published a list of states that, as of December 31, 1998, had laws that preempted stronger local smoking restrictions in one or more of three environments: government worksites, private-sector worksites, and restaurants. This report updates that list and summarizes changes in preemptive state smoke-free indoor air laws during 1999--2004 for these three environments. The findings indicate that almost no progress is being made toward the 2010 goal of eliminating all preemptive state smoke-free indoor air laws, resulting in the potential for lesser health protection. 相似文献

Secondhand smoke (SHS) exposure causes death and disease in both nonsmoking adults and children, including cancer, cardiovascular and respiratory diseases. SHS exposure causes an estimated 46,000 heart disease deaths and 3,400 lung cancer deaths among U.S. nonsmoking adults annually. Adopting policies that completely eliminate smoking in all indoor areas is the only effective way to eliminate involuntary SHS exposure. In 2009, an estimated 696 million aircraft passenger boardings occurred in the United States. A 2002 survey of airport smoking policies found that 42% of 31 large-hub U.S. airports had policies requiring all indoor areas to be smoke-free. To update that finding, CDC analyzed the smoking policies of airports categorized as large-hub in 2010. This report summarizes the results of that analysis, which found that, although 22 (76%) of the 29 large-hub airports surveyed were smoke-free indoors, seven airports permitted smoking in certain indoor locations, including three of the five busiest airports. Although a majority of airports reported having specifically designated smoking areas outdoors in 2010 (79%) and/or prohibiting smoking within a minimum distance of entryways (69%), no airport completely prohibited smoking on all airport property. Smoke-free policies at the state, local, or airport authority level are needed for all airports to protect air travelers and workers at airports from SHS. 相似文献

Despite the great progress made towards smoke-free environments, only 9% of countries worldwide mandate smoke-free restaurants and bars. Smoking was generally not regulated in restaurants and bars in China before 2008. This study was designed to examine the public attitudes towards banning smoking in these places in China. A convenience sample of 814 restaurants and bars was selected in five Chinese cities and all owners of these venues were interviewed in person by questionnaire in 2007. Eighty six percent of current nonsmoking subjects had at least one-day exposure to secondhand smoke (SHS) at work in the past week. Only 51% of subjects knew SHS could cause heart disease. Only 17% and 11% of subjects supported prohibiting smoking completely in restaurants and in bars, respectively, while their support for restricting smoking to designated areas was much higher. Fifty three percent of subjects were willing to prohibit or restrict smoking in their own venues. Of those unwilling to do so, 82% thought smoking bans would reduce revenue, and 63% thought indoor air quality depended on ventilation rather than smoking bans. These results showed that there was support for smoking bans among restaurant or bar owners in China despite some knowledge gaps. To facilitate smoking bans in restaurants and bars, it is important to promote health education on specific hazards of SHS, provide country-specific evidence on smoking bans and hospitality revenues, and disseminate information that restricting smoking and ventilation alone cannot eliminate SHS hazards. 相似文献

Secondhand smoke (SHS) exposure causes lung cancer and cardiovascular and respiratory diseases in nonsmoking adults and children, resulting in an estimated 46,000 heart disease deaths and 3,400 lung cancer deaths among U.S. nonsmoking adults each year. Smoke-free laws that prohibit smoking in all indoor areas of a venue fully protect nonsmokers from involuntary exposure to SHS indoors. A Healthy People 2010 objective (27-13) called for enacting laws eliminating smoking in public places and worksites in all 50 states and the District of Columbia (DC); because this objective was not met by 2010, it was retained for Healthy People 2020 (renumbered as TU-13). To assess progress toward meeting this objective, CDC reviewed state laws restricting smoking in effect as of December 31, 2010. This report summarizes the changes in state smoking restrictions for private-sector worksites, restaurants, and bars that occurred from December 31, 2000 to December 31, 2010. The number of states (including DC) with laws that prohibit smoking in indoor areas of worksites, restaurants, and bars increased from zero in 2000 to 26 in 2010. However, regional disparities remain in policy adoption, with no southern state having adopted a smoke-free law that prohibits smoking in all three venues. The Healthy People 2020 target on this topic is achievable if current activity in smoke-free policy adoption is sustained nationally and intensified in certain regions, particularly the South. 相似文献

BACKGROUND: In 1986, a report of the U.S. Surgeon General concluded that second hand smoke is a cause of disease in healthy non smokers. Subsequent many nations including Tunisia implement smoke-free worksite regulations. The aim of our study is to test air quality in indoor ambient air venues in Tunisia. METHODS: A TSI SidePak AM510 Personal Aerosol Monitor was used to sample, record the levels of respirable suspended particles (RSP) in the air and to assess the real-time concentration of particles less than 2.5 microm in micrograms per cubic meter, or PM2.5. Thirty three venues were sampled in Tunis. The venues were selected to get a broad range of size, location and type of venue. Venues included restaurants and cafés, bars, bus stations, hospitals, offices, and universities. RESULTS: The mean level of indoor air pollution was 296 microg/m3 ranged from 11 microg/m3 to 1,499 microg/m3. The level of indoor air pollution was 85% lower in venues that were smoke-free compared to venues where smoking was observed (p<0.001). Averaged across each type of venue, the lowest levels of indoor air pollution were found in hospitals, offices and universities (52 microg/m3) and the highest level was found in a bar (1,499 micro/m3). CONCLUSION: Hospitality venues allowing indoor air smoking in Tunisia are significantly more polluted than both indoor smoke-free sites and outdoor air in Tunisia. This study demonstrates that workers and patrons are exposed to harmful levels of a known carcinogen and toxin. Policies that prohibit smoking in public worksites dramatically reduce second hand smoke exposure and improve worker and patron health. 相似文献

Exposure to secondhand smoke (SHS) is a major threat to public health. Asian countries having the highest smoking prevalence are seriously affected by SHS. The objective of the study was to measure SHS levels in hospitality venues in seven Asian countries and to compare the SHS exposure to the levels in Western countries. The study was carried out in four types of related hospitality venues (restaurant, café, bar/club and entertainment) in China, India, Japan, Korea, Malaysia, Pakistan and Sri Lanka. Real-time measurement of particulate matter of <2.5 μm aerodynamic diameter (PM2.5) was made during business hour using a handheld laser operated monitor. A total of 168 venues were measured in seven countries. The average indoor PM2.5 level was 137 μg/m3, ranging from 46 μg/m3 in Malaysia to 207 μg/m3 in India. Bar/club had the highest PM2.5 level of 191 μg/m3 and restaurants had the lowest PM2.5 level of 92 μg/m3. The average indoor PM2.5 level in smoking venues was 156 μg/m3, which was 3.6 times higher than non-smoking venues (43 μg/m3). Indoor PM2.5 levels were significantly associated with country, type of venue, smoking density and air exchange rate (p < 0.05). In the seven Asian countries, PM2.5 levels were high due to SHS in public places. The current levels are comparable to the levels in Western countries before the adoption of smoke-free policy. Since Asian country has high prevalence of SHS in public places, there is an urgent need for comprehensive smoke-free regulation in Asian countries. 相似文献

Objectives. We evaluated the impact of comprehensive statewide smoke-free indoor air laws on secondhand smoke (SHS) exposure, asthma prevalence, and asthma-related doctor visits.Methods. We used the 2007–2011 Behavioral Risk Factor Surveillance System data sets. We employed a paired t test to determine whether comprehensive statewide smoke-free indoor air laws reduced SHS exposure. We performed weighted logistic and Poisson regressions to obtain likelihood of reporting asthma symptoms and incidence rate ratio (IRR) of doctor visits owing to severe asthma symptoms.Results. After such laws were enacted, people in states with comprehensive smoke-free indoor air laws had a lower level of SHS exposure (P < .01), decreased odds of reporting current asthma symptoms (adjusted odds ratio [AOR] = 0.57; 95% confidence interval [CI] = 0.51, 0.63), and a decreased frequency of doctor’s visits owing to severe asthma symptoms (IRR = 0.80; 95% CI = 0.69, 0.92) than did their counterparts in fully adjusted models.Conclusions. Comprehensive statewide smoke-free indoor air laws appear to be effective in reducing SHS exposure and improving asthma outcomes. Regulations requiring smoke-free indoor environments and public areas are beneficial, and smoke-free indoor air laws should be enforced in all states.There is an increasing body of literature indicating that secondhand smoke (SHS) exposure has an adverse effect on health. SHS appears to be associated with a high risk of heart disease,1 acute stroke,2 and lung cancer.3 As the harmful consequences of SHS exposure have become increasingly recognized, the US federal government is urging state governments to establish policies to eliminate exposure to SHS. Accordingly, many states have enacted comprehensive statewide smoke-free indoor air laws to improve Americans’ public health by eliminating SHS exposure in 3 indoor locations: worksites, restaurants, and bars. However, not all states have comprehensive smoke-free laws that require the 3 locations to be smoke-free. In 2014, it was reported that only 26 states and the District of Columbia had comprehensive smoke-free laws, whereas 5 states had smoking bans in 2 of the 3 locations, 5 other states had smoking bans in 1 of the locations, and 14 states had no smoking restrictions, designated areas, or separate ventilation laws (Regulation State Comprehensive smoke-free air laws AZ, CO, DE, DC, HI, IL, IA, KS, ME, MD, MA, MI, MN, MT, NE, NJ, NM, NY, ND, OH, OR, RI, SD, UT, VT, WA, WI Smoke-free in 2 locations FL, IN, LA, NV, NC Smoke-free in 1 location AK, ID, NH, PA, TN No smoking restrictions, designated areas, or separate ventilation law AL, AK, CA, CT, GA, KY, MS, MO, OK, SC, TX, VA, WV, WY
