The importance of the issue of secondhand smoking

Census Bureau Messer et al. Thus, in interpreting the results of studies that looked at a possible relationship between smoking bans and acute coronary events, caution must be taken not to attribute a decrease in adverse events solely to a reduction in secondhand smoke or to attribute a decrease in secondhand smoke solely to bans; other factors rather, contribute to the decreases.

Population Based Smoking Cessation: Those factors, therefore, need to be considered in examining epidemiologic evidence. Methods for evaluating tobacco control policies. In contrast, many bans have allowed smoking outside public buildings or more than some stated distance from entrances.

The absence of an established and consistent relationship between active smoking and breast cancer in epidemiologic studies weakens the biologic plausibility of a possible causal association of involuntary smoking with breast cancer. The update of the pooled analyses that follows was prepared by reviewing published studies already included in the meta-analyses conducted by Hackshaw and colleagues and Zhong and colleaguesas well as the new studies discussed in the Appendix at the end of this chapter.

The study found that when the population was exposed about four times per month to antismoking advertising campaigns, smoking prevalence decreased by 0. At the present time, the evidence is considered suggestive but not sufficient to infer a causal association between cigarette smoking and the risk of developing asthma in adolescents or adults or between smoking and the risk of asthma exacerbations in adolescents HHS, American Journal of Public Health 97 American Journal of Public Health 92 6: Not surprisingly, associations did not reach statistical significance in all studies because of variations in the sample sizes; some had modest sample sizes with low statistical power.

Reductions in tobacco smoke pollution and increases in support for smoke-free public places following the implementation of comprehensive smoke-free workplace legislation in the Republic of Ireland: Impact of tobacco control policies and mass media campaigns on monthly adult smoking prevalence.

Therefore, smoking behaviors often change before and beyond the restrictions put into place by legislation for example, quitting or voluntary smoke-free workplace policies in anticipation of a ban, reduction in smoking in homesand such changes would contribute to the magnitude of changes in health outcomes seen after the implementation of a smoking ban.

Tobacco Control 15 Suppl 3: For example, some studies showed that increasing cigarette prices reduces demand for cigarettes IOM, Cigarette smoking is an established cause of abdominal aortic aneurysm HHS, Accessed March 31,from http: Previous Regulations and Characteristics and Enforcement of Smoking Bans Other factors that could affect the results of studies of smoking bans and acute coronary events are the extent of smoking restrictions in place before the bans, the characteristics of the smoking bans themselves, and how well the bans are enforced.

American Journal of Public Health 92 6: Hackshaw and colleagues demonstrated that the risk estimate obtained directly from a meta-analysis of epidemiologic studies was compatible with the risk estimate calculated indirectly from a linear extrapolation of risk among active current smokers.

Therefore, smoking behaviors often change before and beyond the restrictions put into place by legislation for example, quitting or voluntary smoke-free workplace policies in anticipation of a ban, reduction in smoking in homesand such changes would contribute to the magnitude of changes in health outcomes seen after the implementation of a smoking ban.

A Report of the Surgeon General: How Tobacco Smoke Causes Disease: Based on this evidence, cigarette smoking was judged to be causally associated with periodontitis.

Vandenbroucke conducted a formal statistical analysis and found no evidence of a selective publication bias. Secondhand smoke is responsible for betweenandlower respiratory tract infections in infants and children under 18 months of age, resulting in between 7, and 15, hospitalizations each year.

They estimated that allowing for a publication bias could reduce a pooled RR of 1. Significantly increased risks were observed regardless of the sample size: Tobacco Control 17 4: Ine-cigarettes became the most commonly used tobacco product among U. Potential confounders were considered in both studies and their results were very similar to those reported by Hirayama A portion of the overall decline in smoking prevalence and intensity over the past 25 years can be attributed to general tobacco-control interventions price increases and stronger antismoking culture.

The body of epidemiologic research now includes a number of large studies that were designed specifically to limit misclassification and confounding. A report of the surgeon general. In addition, if a ban is not complied with or enforced, changes in health effects would not be expected.

Emerging Issues in Tobacco Use Major advances have been made in recent years to address the tobacco epidemic: Although some of these studies were small and the quality of the methods uncertain, three studies are large and well-designed.

Comprehensive programs and voluntary actions could lead to larger decreases in smoking prevalence and a subsequent decrease in adverse health effects.GoalReduce illness, disability, and death related to tobacco use and secondhand smoke agronumericus.comewScientific knowledge about the health effects of tobacco use has increased greatly since the first Surgeon General’s report on tobacco was released in ,2,3,4 Since the publication of that report, more than 20 million Americans have died because of smoking Secondhand smoking is a leading cause of preventable death, and the US Surgeon General’s report was entirely devoted to it.

8 The report concluded that the evidence was sufficient to support immediate adverse effects on the cardiovascular system and, importantly, to allow deduction of a causal relationship between secondhand smoke and.
