Abstract
Importance Smoking causes considerable noncommunicable diseases, perinatal morbidity, and mortality. Objective To investigate the associations of population-level tobacco-control policies with health outcomes. Data Sources PubMed, EMBASE, Web of Science, Cumulated Index to Nursing and Allied Health Literature, and EconLit were searched from inception to March 2021 (updated on 1 March 2022). References were manually searched. Study Selection Studies reporting on associations of population-level tobacco control policies with health-related outcomes were included. Data were analyzed from May to July 2022. Data Extraction and Synthesis Data were extracted by 1 investigator and cross-checked by a second investigator. Analyses were conducted using the Preferred Reporting Items for Systematic Reviews and Meta-analyses reporting guideline. Main Outcomes and Measures The primary outcomes were respiratory system disease (RSD), cardiovascular disease (CVD), cancer, mortality, hospitalization, and health care utilization. The secondary outcomes were adverse birth outcomes, such as low birth weight and preterm birth. Random-effects meta-analysis was used to estimate pooled odds ratios (ORs) and 95% CIs. Results Of 4952 records identified, 144 population-level studies were included in the final analysis; 126 studies (87.5%) were of high or moderate quality. The most frequently reported policies were smoke-free legislation (126 studies), followed by tax or price increases (14 studies), multicomponent tobacco control programs (12 studies), and a minimum cigarette purchase age law (1 study). Smoke-free legislation was associated with decreased risk of all CVD events (OR, 0.90; 95% CI, 0.86-0.94), RSD events (OR, 0.83; 95% CI, 0.72-0.96), hospitalization due to CVD or RSD (OR, 0.91; 95% CI, 0.87-0.95), and adverse birth outcomes (OR, 0.94; 95% CI, 0.92-0.96). These associations persisted in all sensitivity and subgroup analyses, except for the country income category, for which a significant reduction was only observed in high-income countries. In meta-analysis, there was no clear association of tax or price increases with adverse health outcomes. However, for the narrative synthesis, all 8 studies reported statistically significant associations between tax increases and decreases in adverse health events. Conclusions and Relevance In this systematic review and meta-analysis, smoke-free legislation was associated with significant reductions in morbidity and mortality related to CVD, RSD, and perinatal outcomes. These findings support the need to accelerate the implementation of smoke-free laws to protect populations against smoking-related harm.

Gambaryan M, Kontsevaya A, Drapkina O. Impact of National Tobacco Control Policy on Rates of Hospital Admission for Pneumonia: When Compliance Matters. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2023; 20:ijerph20105893. [PMID: 37239619 DOI: 10.3390/ijerph20105893] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/03/2023] [Revised: 05/10/2023] [Accepted: 05/12/2023] [Indexed: 05/28/2023]
Abstract
A number of studies claim that tobacco control (TC) regulations are associated with reductions in smoking-related hospitalisation rates, but very few have estimated the impact of TC laws (TCL) at both countrywide and regional levels, and none of them have studied the impact of TCL in relation to compliance with TC regulations. This study evaluates the effects of Russian TCL on hospital admission (HA) rates for pneumonia countrywide and in 10 Russian regions and the extent of these effects in connection with the compliance with TCL. Methods: HA rates for pneumonia from 2005-2019 were analysed to compare the periods before and after the adoption of TCL in 2013. An interrupted time series design and a Poisson regression model were used to estimate the immediate and long-term effects of TCL on pneumonia annual hospitalisation rates after the TCL adoption, compared with the pre-law period. The 10 Russian regions were compared using the TCL implementation scale (TCIS) developed on the basis of the results of the Russian TC policy evaluation survey; Spearman's rank correlation and linear regression models were employed. Results showed a 14.3% reduction in HA rates for pneumonia (RR 0.88; p = 0.01) after the adoption of TCL in Russia with significant long-term effect after 2013 (RR 0.86; p = 0.006). Regions with better enforcement of TCL exhibited greater reductions in pneumonia HA rates (rsp = -0.55; p = 0.04); (β = -4.21; p = 0.02). Conclusions: TCL resulted in a sustained reduction in pneumonia hospitalisation rates, but these effects, varying by region, may depend on the scale of the TCL enforcement.

Trends in Hospital Admissions for Chronic Obstructive Pulmonary Diseases After Comprehensive Tobacco Control Policies in Beijing, China. Nicotine Tob Res 2022; 24:1978-1984. [PMID: 35808957 DOI: 10.1093/ntr/ntac137] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/01/2021] [Revised: 04/12/2022] [Accepted: 05/30/2022] [Indexed: 01/03/2023]
Abstract
INTRODUCTION Only a few studies have examined the effectiveness of tobacco control policies on respiratory conditions, and the results were less consistent. The 2015 Beijing tobacco control policy package incorporating all six components of MPOWER has been implemented since Jun 2015. The present study aimed to evaluate the impact of a comprehensive tobacco control policy package on hospital admissions for chronic obstructive pulmonary disease (COPD) in Beijing, China. AIMS AND METHODS An interrupted time-series study was conducted based on the hospital admission information for about 18 million residents, who were covered by the Beijing Medical Claim Data for Employees from January 2013 to June 2017. The average percentage change of COPD hospital admission rates and reductions in hospital admission numbers were estimated by segmented Poisson regression models. RESULTS There were 54 040 COPD hospital admissions with a crude rate of 67.2 per 100 000 residents during the observational period. After the implementation of the policy package, the hospital admission rates of COPD were reduced by -14.7% (95%CI: -17.8%, -11.5%) immediately. The secular trend was slowed down by -3.0% (95% CI: -5.6%, -0.4%) annually. A total of 5 581 reductions in COPD hospital admissions were estimated during the 25 months post-law period, accounting for 17.5% (95% CI: 12.5%, 22.5%) of overall COPD hospital admissions. More reductions were shown in males and those aged over 65 years old. CONCLUSIONS The results indicated significant protections against hospitalization of COPD after the 2015 Beijing comprehensive tobacco control policy package. The results provide support for public health benefits for respiratory conditions from WHO-recommended tobacco control measures. IMPLICATIONS Only a few studies have examined the effectiveness of tobacco control policies on respiratory conditions, and the results were less consistent. Based on medical records for about 18 million residents, this study showed an association between comprehensive tobacco control policies and significant reductions of hospital admissions for chronic obstructive pulmonary disease. The results provide support for public health benefits for respiratory conditions from WHO-recommended tobacco control measures.

Abstract
OBJECTIVES Given the growing interest worldwide in applying public policies to improve human health, we undertook a systematic review of studies investigating whether public policies targeting unhealthy products could reduce cardiovascular diseases. STUDY DESIGN This study was a systematic review of the literature. METHODS We searched research studies published in 2000-2020 from major databases, including MEDLINE and Embase. We followed Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and narratively synthesized the studies based on vote counting and direction of the intervention effect. RESULTS Ninety-eight studies, mostly from high-income countries, met the inclusion criteria. Most studies were on public policies targeting sugar-sweetened beverages and tobacco, followed by alcohol, sugar, salt, and junk foods. Overall, many reported that several fiscal, regulatory, and educational policies generated beneficial effects of reducing the diseases. Those studies that reported no or limited effects highlighted several sociodemographic and health risk characteristics and design and implementation aspects of the policy interventions as factors limiting the policy effects; most of these are modifiable with appropriate policy interventions. For instance, low magnitude of tax, substitution with other unhealthy products, firms' competitive response strategies, pre-existence of smoking bans, incremental enactment of smoking regulations, degree of enforcement, and various sociocultural factors minimized the effects of the policies. CONCLUSION The literature supports a growing consensus on the beneficial effects of public policy for improving human health. The design and implementation of public policies must address various impeding factors and incorporate appropriate remedial measures. Further research is needed from low- and middle-income countries and on whether and how multiple policy instruments work in tandem.

Impact of Qingdao's smoke-free legislation on hospitalizations and mortality from acute myocardial infarction and stroke: an interrupted time-series analysis. Addiction 2020; 115:1561-1570. [PMID: 31961014 DOI: 10.1111/add.14970] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/01/2019] [Revised: 05/31/2019] [Accepted: 01/14/2020] [Indexed: 11/28/2022]
Abstract
BACKGROUND AND AIMS More than 20 cities in China have enacted local smoke-free laws that prohibit smoking in public places. Only two of these cities have examined the health impact of the law. Enacted in 2013, Qingdao's smoke free-law was stricter than most other municipal smoke-free laws because it did not allow designated smoking rooms. This study aimed to estimate the impact of Qingdao's smoke-free legislation on acute myocardial infarction (AMI) and stroke. DESIGN, SETTING AND PARTICIPANTS We used an interrupted time-series design adjusting for underlying secular trends, seasonal patterns and meteorological factors to estimate the impact of the smoke-free law on AMI and stroke events among permanent residents aged 35 years or older in Qingdao, China. The study period was from 1 January 2010 to 31 December 2015, with a post-ban follow-up of approximately 2.5 years. MEASUREMENT Outcome measures were weekly numbers of hospitalizations and deaths due to AMI/stroke. FINDINGS A total of 10 371 and 56 101 patients were hospitalized, with a principal discharge diagnosis of AMI and stroke, respectively; 32 196 AMI and 49 711 stroke deaths occurred during the study period. Following the smoke-free legislation, an incremental 20% [95% confidence interval (CI) = 14-26%] and 8% (95% CI = 3-13%) decrease per year was observed in AMI and stroke hospitalization rates, respectively. Neither the immediate nor gradual change in AMI nor stroke mortality rates associated with the law was statistically significant (P > 0.05). Post-hoc subgroup analyses indicated that statistically significant reductions in AMI hospitalizations were evident among both the 35-64 (18% per year, 95% CI = 12-27%) and 65-84 (20% per year, 95% CI = 12-27%) age groups. Statistically significant reductions in stroke hospitalization were only in the older subgroup (13% per year, 95% CI = 8-18%). CONCLUSIONS The 2013 smoke-free legislation in Qingdao, China was associated with reduction in hospitalization from acute myocardial infarction and stroke among permanent residents aged 35 years or older. There was no statistically significant reduction in mortality from acute myocardial infarctions or stroke.

Association between a comprehensive smoking ban and hospitalization for acute myocardial infarction: An observational study in the Autonomous Community of Valencia, Spain. Rev Port Cardiol 2020; 39:77-84. [PMID: 32291119 DOI: 10.1016/j.repc.2019.04.009] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/20/2018] [Revised: 03/27/2019] [Accepted: 04/19/2019] [Indexed: 12/31/2022] Open
Abstract
OBJECTIVE To assess the association between a comprehensive smoking ban and hospitalization rates for acute myocardial infarction (AMI). METHODS An observational study was conducted to assess changes in hospital admission rates for AMI in the Autonomous Community of Valencia, Spain (population 5 million), during the period 1995-2013. Law 28/2005 prohibited smoking in all enclosed spaces (public and private), and Law 42/2010 extended the ban to bars and restaurants as well as children's playgrounds and access areas of schools and hospitals. Data on hospital admissions were obtained from the Hospital Discharge Database (CMBD) of the Autonomous Community. Annual hospital admission rates per 100000 population for AMI (ICD-9-CM code 410) for men and women were calculated. RESULTS Adjusted hospital admission rates per 100000 population for AMI decreased markedly from 141.1 in 2005 to 119.2 in 2007, with a further reduction to 102.9 in 2013. Reductions in hospital admission were recorded in both men and women, but the downward trends were stronger in women. CONCLUSION The Spanish comprehensive smoking ban was associated with a marked reduction in the adjusted rate of hospital admissions due to AMI in the Autonomous Community of Valencia. This decrease in the number of persons requiring in-patient care due to AMI is important from both a health care and a societal perspective.

The limits of single-group interrupted time series analysis in assessing the impact of smoke-free laws on short-term mortality. THE INTERNATIONAL JOURNAL OF DRUG POLICY 2019; 73:112-120.

Abstract
BACKGROUND Decreases in circulatory/respiratory morbimortality after the January-2006 Spanish partial smoke-free law have been found using designs without control groups, such as single-group interrupted time series (ITS), which are prone to biases. The aim was to reassess the law's impact on mortality using ITS designs with robustness checks. METHODS A comprehensive cohort of people aged ≥25 in each calendar-year of 2002-2007, living in 13 of 18 Spanish regions, was followed up between 01/2002 and 12/2007. The law included a smoking ban in indoor public and workplaces, allowing exceptions in catering, hospitality and leisure venues, and other interventions. Post-law changes in monthly coronary/respiratory mortality were estimated using segmented regression, adjusting for relevant covariates, including seasonality, extreme temperatures, influenza incidence and air pollution. The validity of results was assessed using control outcomes, hypothetical law dates, and non-equivalent control groups, analysing their results as difference-in-differences (DID) designs. RESULTS Significant immediate post-law decreases in coronary, respiratory and non-tobacco-related mortality were observed among people aged ≥70. A significant immediate post-law decrease in respiratory mortality (-12.7%) was also observed among people age 25-69, although this was neutralized by a subsequent upward trend before 1.5 years. More favourable post-law changes in coronary/respiratory mortality among the target (people aged 25-69) than control groups (people aged ≥70 or women aged ≥80) were not identified in DID designs. Establishing hypothetical law dates, immediate decreases began in February/March 2005 with maxima between April and July 2005. CONCLUSIONS After robustness checks, the results do not support a clear positive impact of the 2006 Spanish smoke-free law on short-term coronary/respiratory mortality. The favourable immediate changes observed pre- and post-law could derive mainly from the harvesting effect of the January-2005 cold wave. This highlights the risks of assessing the impact of health interventions using both morbimortality outcomes and designs without a control group and adequate robustness checks.

Abstract
Background To examine the impact of comprehensive smoke-free legislation (SFL) (Law 42/2010) on the incidence and prevalence of adult asthma and coronary disease in primary health care (PHC) patients from three Spanish regions, overall and stratified by sex. Methods Longitudinal observational study conducted between 2007 and 2013 in the population over 15 years of age assigned to 66 PHC teams in Catalonia, Navarre and the Balearic Islands. Crude rates and age-standardized (truncated: asthma ≥ 16 years and coronary disease ≥ 35 years) incidence and prevalence rates using the direct method based on the European Standard Population were estimated based on data from PHC electronic health records. Joinpoint analysis was used to analyse the trends of age-standardized incidence and prevalence rates. Trends were expressed as annual percentage change and average annual percent change (AAPC). Results The standardized asthma incidence rate showed a non-significant downward trend and the standardized prevalence rates rose significantly in the three regions. Standardized coronary disease incidence and prevalence rates were considerably higher for men than for women in all regions. The standardized coronary disease incidence rates in Catalonia (AAPC: -8.00%, 95% CI: -10.46; -5.47) and Navarre (AAPC: -3.66%, 95% CI: -4.95;-2.35) showed a significant downward trend from 2007 to 2013, overall and by sex. The standardized coronary disease prevalence trend rate increased significantly in the whole period in Catalonia and the Balearic Islands, although a non-significant downward trend was observed from 2010 in Catalonia. Conclusion No changes in the trends of adult asthma and coronary disease in PHC Spanish patients were detected after the introduction of comprehensive SFL.

Abstract
In our latest update of the evidence on smoking bans and heart disease we summarize 59 studies. We take account of the underlying trends in incidence rates as far as possible by using control data in eight studies, and by adjustment based on observed trends in cases pre- and post-ban in 40 studies, being unable to make an adjustment in the remaining 11 studies. Overall, based on 62 independent estimates from the 59 studies, we estimate that bans reduce incidence by 5.0% (95% CI 3.2-6.8%), though this estimate reduces to 2.9% (0.01-5.6%) when we exclude regional estimates where national estimates are available, and studies where trend adjustment is not possible. For 25 of the studies, quadratic rather than linear adjustment is possible, but this hardly affects the overall estimates. Ban effects are somewhat greater when the pre-ban period studied is relatively short, and in smaller studies. We compare our findings with those in other recent reviews, one of which totally ignored underlying trends and results from control populations. We discuss reasons why we believe there is likely to be a true small effect of smoking bans, and weaknesses in the data which preclude reaching any very confident conclusion.

Abstract
INTRODUCTION AND OBJECTIVES To evaluate the impact of 2 smoking bans enacted in 2006 (partial ban) and 2011 (comprehensive ban) on hospitalizations for cardiovascular disease in the Spanish adult population. METHODS The study was performed in 14 provinces in Spain. Hospital admission records were collected for acute myocardial infarction (AMI), ischemic heart disease (IHD), and cerebrovascular disease (CVD) in patients aged ≥ 18 years from 2003 through 2012. We estimated immediate and 1-year effects with segmented-linear models. The coefficients for each province were combined using random-effects multivariate meta-analysis models. RESULTS Overall, changes in admission rates immediately following the implementation of the partial ban and 1 year later were -1.8% and +1.2% for AMI, +0.1 and +0.4% for IHD, and +1.0% and +2.8% for CVD (P>.05). After the comprehensive ban, immediate changes were -2.3% for AMI, -2.6% for IHD, and -0.8% for CVD (P>.05), only to return to precomprehensive ban values 1 year later. For patients aged ≥ 65 years of age, immediate changes associated with the comprehensive ban were -5.0%, -3.9%, and -2.3% for AMI, IHD, and CVD, respectively (P<.05). Again, the 1-year changes were not statistically significant. CONCLUSIONS In Spain, smoking bans failed to significantly reduce hospitalizations for AMI, IHD, or CVD among patients ≥ 18 years of age. In the population aged ≥ 65 years, hospital admissions due to these diseases showed significant decreases immediately after the implementation of the comprehensive ban, but these reductions disappeared at the 1-year evaluation.

Abstract
BACKGROUND Smoke-free legislation has been associated with lower rates of cardiovascular disease hospital admissions in ecological studies. However, prior studies lacked detailed information on individual-level factors (eg, sociodemographic and clinical characteristics) that could potentially confound associations. Our objective was to estimate associations of smoke-free policies with incident cardiovascular disease in a longitudinal cohort after controlling for sociodemographics, cardiovascular disease risk factors, and policy covariates. METHODS Longitudinal data from 3783 black and white adults in the CARDIA study (Coronary Artery Risk Development in Young Adults; 1995-2015) were linked to state, county, and local 100% smoke-free policies in bars, restaurants, and nonhospitality workplaces by Census tract. Extended Cox regression estimated hazard ratios (HRs) of incident cardiovascular disease associated with time-dependent smoke-free policy exposures. Models were adjusted for sociodemographic characteristics, cardiovascular disease risk factors, state cigarette tax, participant-reported presence of a smoking ban at their workplace, field center, and metropolitan statistical area poverty. RESULTS During a median follow-up of 20 years (68 332 total person-years), 172 participants had an incident cardiovascular disease event (2.5 per 1000 person-years). Over the follow-up period, 80% of participants lived in areas with smoke-free policies in restaurants, 67% in bars, and 65% in nonhospitality workplaces. In fully adjusted models, participants living in an area with a restaurant, bar, or workplace smoke-free policy had a lower risk of incident cardiovascular disease compared with those in areas without smoke-free policies (HR, 0.75, 95% confidence interval, 0.49-1.15; HR, 0.76, 95% confidence interval, 0.47-1.24; HR, 0.54, 95% confidence interval, 0.34-0.86, respectively; HR, 0.58, 95% confidence interval, 0.33-1.00 for living in an area with all 3 types of policies compared with none). The estimated preventive fraction was 25% for restaurant policies, 24% for bar policies, and 46% for workplace policies. CONCLUSIONS Consistent with prior ecological studies, these individual-based data add to the evidence that 100% smoke-free policies are associated with lower risk of cardiovascular disease among middle-aged adults.

Abstract
Objective To evaluate the impact of a complete smoking ban in enclosed spaces on the incidence of acute myocardial infarction in Chile. Methods The population-based study involved residents of urban areas, where 80% of the Chilean population live, aged 20 years or older who had a myocardial infarction. Monthly myocardial infarction incidence and mortality rates at health-care facilities between January 2011 and December 2014 were derived from admission and mortality databases. Regression discontinuity methods were used to estimate the near-immediate impact on disease incidence of enforcing smoke-free legislation in March 2013. The same analysis was performed for ischaemic stroke, degenerative disc disease and colon cancer. Data on the concentration of fine respirable particulates were included in an additional analysis of myocardial infarction incidence in the Santiago metropolitan area. Results The enforcement of smoke-free legislation was associated with an abrupt, near-immediate decline of 0.639 cases of myocardial infarction per 100 000 adults per month (95% confidence interval, CI: 0.242 to 1.036; relative decline: 7.8%). Similar declines were observed in men and women and in people aged over and under 70 years. However, enforcement of the legislation was not associated with a significant change in the rate of ischaemic stroke, degenerative disc disease or colon cancer. The abrupt decline in myocardial infarction incidence was also observed when data on fine respirable particulates were included in an analysis for Santiago. Conclusion The enforcement of extensive smoke-free legislation in Chile was associated with an abrupt, near-immediate decline in the incidence of myocardial infarction.

Changes in hospitalizations for chronic respiratory diseases after two successive smoking bans in Spain. PLoS One 2017; 12:e0177979. [PMID: 28542337 PMCID: PMC5443522 DOI: 10.1371/journal.pone.0177979] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/16/2016] [Accepted: 05/05/2017] [Indexed: 11/21/2022] Open
Abstract
Background Existing evidence on the effects of smoke-free policies on respiratory diseases is scarce and inconclusive. Spain enacted two consecutive smoke-free regulations: a partial ban in 2006 and a comprehensive ban in 2011. We estimated their impact on hospital admissions via emergency departments for chronic obstructive pulmonary disease (COPD) and asthma. Methods Data for COPD (ICD-9 490–492, 494–496) came from 2003–2012 hospital admission records from the fourteen largest provinces of Spain and from five provinces for asthma (ICD-9 493). We estimated changes in hospital admission rates within provinces using Poisson additive models adjusted for long-term linear trends and seasonality, day of the week, temperature, influenza, acute respiratory infections, and pollen counts (asthma models). We estimated immediate and gradual effects through segmented-linear models. The coefficients within each province were combined through random-effects multivariate meta-analytic models. Results The partial ban was associated with a strong significant pooled immediate decline in COPD-related admission rates (14.7%, 95%CI: 5.0, 23.4), sustained over time with a one-year decrease of 13.6% (95%CI: 2.9, 23.1). The association was consistent across age and sex groups but stronger in less economically developed Spanish provinces. Asthma-related admission rates decreased by 7.4% (95%CI: 0.2, 14.2) immediately after the comprehensive ban was implemented, although the one-year decrease was sustained only among men (9.9%, 95%CI: 3.9, 15.6). Conclusions The partial ban was associated with an immediate and sustained strong decline in COPD-related admissions, especially in less economically developed provinces. The comprehensive ban was related to an immediate decrease in asthma, sustained for the medium-term only among men.
