Abstract
BACKGROUND It is generally accepted that living in families where there are smokers, children are stressed not only by the harmful physical exposure to second-hand and third-hand tobacco smoke, but also by the negative models of the adult relatives' behaviour, as relatives who smoke can inspire children to imitate this behaviour, influencing attitudes towards, and early experiments with smoking. In this paper, some of the most important results about influence of family smoking on the effects of the anti-smoking educational programme "Non-smoking Is Normal" are described. METHODS The school-based programme was created by medical and educational specialists and targets children at the first level of primary schools (aged from 6 to 11 years). The data about interesting outcomes of the programme (knowledge, attitudes, behaviour) were collected by anonymous questionnaire, administered twice in each school year: one month before the complex of 5 lectures (pre-tests) and 4-5 months after the last lecture (post-tests). The sample of participants (860-910) was divided into four groups, according to the intervention and family backrounds: (1) programme children from smoking families "P-S"; (2) control children from smoking families "C-S"; (3) programme children from non-smoking families "P-NS"; (4) control children from non-smoking families "C-NS". The differences in the frequency of children's answers were analysed using the tests in statistic Epi Info software, version 6.04a (chi-square, Mantel Haenszel, Yates, Fisher). RESULTS In the programme group, the number of children with smoking relatives was significantly higher than in the control group (80.1% vs. 73.0%, p < 0.01) as well as of those who reported frequent/daily exposure to secondhand smoke at homes and/or in cars (49.5% vs. 40.0%, p < 0.01). Smoking families significantly influenced the children's seeking of smoking friends (40% vs. 17%, p < 0.01). The programme has significantly increased the amount of knowledge about health risks of smoking. Both in the programme and control groups of children from non-smoking families, the frequency of critics of adults smoking was significantly higher all the time of the study (p < 0.05 and 0.01 resp.); however, the programme influenced children's opinions about smoking (criticism) only partially. Children's actual intentions about their smoking in the future was fully influenced by their smoking household environment: the number of "future no-smokers" has decreased in time and was significantly less frequent among children from smoking families (p < 0.01). The frequency of those willing to smoke significantly increased within the period between 3rd and 5th grades, both in the programme and the control groups (p < 0.01). An almost linear increase of active experimentations with cigarette smoking in follow-up monitoring was seen, trends of smoking children were steeper in groups from smoking families. The number of experiments with smoking was significantly lower in programme children of non-smoking parents only at the end of the study (p < 0.05). CONCLUSIONS Despite of the effort to initiate parental participation on the primary prevention of smoking, we have confirmed that smoking in families decreased the efficacy of anti-smoking intervention targeted on young children at school age.

Abstract
Tobacco use started several centuries ago and increased markedly after the invention of the cigarette making machine. Once people start smoking they find it difficult to quit the habit. This is due to the addictive effect of nicotine in tobacco smoke. Various epidemiologic and laboratory studies clearly showed that smoking is associated with various diseases such as heart diseases, asthma and emphysema and the associated increase in morbidity and mortality of smokers. Several studies implicate nicotine as the causative factor in tobacco smoke. Apart from nicotine, various carcinogens also occur in tobacco smoke resulting in an increase in the incidence of cancer in smokers. While the smoking habit is decreasing in developed countries, tobacco use increases in the developing countries. Smoking prevalence is also highest in poor communities and amongst those with low education levels. It is important to note that, although ther is a decline in the number of smokers in the developed countries, there is a three to four decades lag between the peak in smoking prevalence and the subsequent peak in smoking related mortality. It has been shown that maternal smoking induces respiratory diseases in the offspring. There is also evidence that parental smoking may program the offspring to develop certain diseases later in life. Various studies showed that maternal nicotine exposure during pregnancy and lactation via tobacco smoke of nicotine replacement therapy (NRT), program the offspring to develop compromised lung structure later in life with the consequent compromised lung function. This implies that NRT is not an option to assist pregnant or lactating smokers to quit the habit. Even paternal smoking may have an adverse effect on the health of the offspring since it has been shown that 2nd and 3rd hand smoking have adverse health consequences for those exposed to it.

Abstract
Environmental tobacco smoke is a major contributor to indoor air pollution. Dust and surfaces may remain contaminated long after active smoking has ceased (called 'thirdhand' smoke). Polycyclic aromatic hydrocarbons (PAHs) are known carcinogenic components of tobacco smoke found in settled house dust (SHD). We investigated whether tobacco smoke is a source of PAHs in SHD. House dust was collected from 132 homes in urban areas of Southern California. Total PAHs were significantly higher in smoker homes than nonsmoker homes (by concentration: 990 ng/g vs 756 ng/g, p = 0.025; by loading: 1650 ng/m(2) vs 796 ng/m(2), p = 0.012). We also found significant linear correlations between nicotine and total PAH levels in SHD (concentration, R(2) = 0.105; loading, R(2) = 0.385). Dust collected per square meter (g/m(2)) was significantly greater in smoker homes and might dilute PAH concentration in SHD inconsistently. Therefore, dust PAH loading (ng PAH/m(2)) is a better indicator of PAH content in SHD. House dust PAH loadings in the bedroom and living room in the same home were significantly correlated (R(2) = 0.468, p < 0.001) suggesting PAHs are distributed by tobacco smoke throughout a home. In conclusion, tobacco smoke is a source of PAHs in SHD, and tobacco smoke generated PAHs are a component of thirdhand smoke.

Abstract
OBJECTIVES To assess the impact of different home-smoking rules and smoking habits of cohabitant on environmental tobacco smoke (ETS) exposure of children. METHODS Information about 396 Italian children (5-11 years old) and cohabitants' smoking habits was collected by a questionnaire. Exposure assessment was performed by determination of urinary cotinine (u-cotinine). RESULTS Median u-cotinine concentrations in children significantly increased in a similar fashion as theoretical ETS exposure increase: cohabitants do not smoke (1.79 μg/g creatinine), cohabitant(s) smoker(s) never smoke at home (2.84), smoke at home only when children are out (3.90), and smoke at home even if children are in (6.02). Median u-cotinine levels of exposed children were associated to the strength of cohabitant's smoking behaviours when smoker(s) consume daily a high number of cigarettes (≥ 20) respect to light consumption (1-9) (4.52 and 3.24 μg/g creatinine). CONCLUSIONS The magnitude of ETS exposure in children is correlated with smoking habits and home-smoking precautions adopted by their cohabitants. Educational interventions on parents are essential to increase their awareness about ETS exposure and to teach correct behaviours to protect health of kids, especially in household environment.

Abstract
INTRODUCTION The health effects on young children of exposure to secondhand smoke (SHS) are well described. Recent work suggests that over one quarter of school-aged children in Scotland are regularly exposed to SHS in the home. The study was designed to describe SHS exposure in preschool children whose mothers smoked and identify factors that influence exposure. METHODS Smoking mothers with at least one child aged 1-5 years were recruited to the Reducing Families' Exposure to Secondhand Smoke in the Home study. Concentrations of airborne particulate matter less than 2.5 μm in size (PM(2.5)) in the home were measured together with child's salivary cotinine. Demographics including age, accommodation type, socioeconomic status, and number of cigarettes smoked at home were recorded. RESULTS Data were collected from 54 homes. In 89% of the homes, concentrations of PM(2.5) exceeded health-based guidance values at some point of the day. Household PM(2.5) concentrations were highest during the evening hours of 6 p.m. to midnight. Younger children had higher salivary cotinine concentrations than older children, and the geometric mean of salivary cotinine was 2.36 ng/ml. Household smoking restrictions and maternal confidence in enforcing smoking restrictions in their own home were strongly associated with child's SHS exposure. CONCLUSIONS Preschool children's exposure to SHS in homes where the mother smokes is considerable. Interventions and policy development to increase parental awareness of the health effects of SHS and provide parents with the confidence to implement smoke-free households are required to reduce the SHS exposure of preschool age children.

Abstract
OBJECTIVE To describe lessons learned in developing the CEASE tobacco control intervention. METHODS Descriptive report. RESULTS Tobacco use and tobacco smoke exposure harm families in a multitude of ways. The child health care setting is the ideal location to address parental smoking and tobacco smoke exposure in children. Few interventions have been developed specifically for families in the child health care setting. One such intervention, the CEASE program, was developed with assistance from tobacco control experts, pediatric researchers, policy makers, and child health care clinicians to address parental smoking. CONCLUSION An effective tobacco cessation intervention can be developed in a systematic way that may not require extensive resources and expertise.

Abstract
BACKGROUND Young children can be protected from much of the harm from tobacco smoke exposure if their parents quit smoking. Some researchers encourage parents to quit for their children's benefit, but the evidence for effectiveness of such approaches is mixed. OBJECTIVE To perform a systematic review and meta-analysis to quantify the effects of interventions that encourage parental cessation. METHODS We searched PubMed, the Cochrane Library, Web of Science, and PsycINFO. Controlled trials published before April 2011 that targeted smoking parents of infants or young children, encouraged parents to quit smoking for their children's benefit, and measured parental quit rates were included. Study quality was assessed. Relative risks and risk differences were calculated by using the DerSimonian and Laird random-effects model. RESULTS Eighteen trials were included. Interventions took place in hospitals, pediatric clinical settings, well-baby clinics, and family homes. Quit rates averaged 23.1% in the intervention group and 18.4% in the control group. The interventions successfully increased the parental quit rate. Subgroups with significant intervention benefits were children aged 4 to 17 years, interventions whose primary goal was cessation, interventions that offered medications, and interventions with high follow-up rates (>80%). CONCLUSIONS Interventions to achieve cessation among parents, for the sake of the children, provide a worthwhile addition to the arsenal of cessation approaches, and can help protect vulnerable children from harm due to tobacco smoke exposure. However, most parents do not quit, and additional strategies to protect children are needed.

Abstract
INTRODUCTION A significant proportion of children in the United States remain exposed to secondhand smoke (SHS). We are reporting on relationships observed between parental report of their child's SHS exposure in two groups of children (ages 2-5 years and 9-14 years) with a biological marker of long-term SHS exposure, hair nicotine. METHODS Participants were healthy children recruited via convenience sampling for two age groups: 2-5 years and 9-14 years. The presence and amount of SHS exposure were assessed by both questionnaire and hair sampling for nicotine determination. RESULTS A total of 115 participants were recruited (54 toddlers and 61 youth). The groups were similar in terms of demographics and reported SHS exposure. Hair nicotine levels were significantly different by age group, with toddlers having higher levels than youth. The most important independent determinants of hair nicotine were toddler age group, receiving Medicaid for health insurance, and number of smokers the subject was exposed to in 24 hr. CONCLUSIONS Our findings suggest that young children who are insured by Medicaid have higher levels of hair nicotine, a biomarker of SHS exposure, when compared with an older age group. Further efforts to protect this vulnerable population and mitigate their lifetime risks of SHS exposure-related morbidities are warranted.

Abstract
A novel, highly selective method for the determination of nicotine, N-nitrosamines and tobacco-specific nitrosamines (TSNAs) in indoor dust samples is presented in this study. Samples were extracted by in-cell clean-up pressurized liquid extraction (PLE) that allows high extraction efficiency with moderate consumption of organic solvents. The extracts were analyzed by comprehensive gas chromatography and detected with a nitrogen chemiluminiscence detector (GC×GC-NCD) that provided enhanced selectivity and sensitivity for organic nitrogen containing compounds. Method validation showed good linearity, repeatability and reproducibility (%RSD<8%). Recovery was higher than 80% for most target compounds and limits of detection lower than 16 ng g(-1). The method was used for the determination of the nitrosamine target compounds in house dust samples from both smoking and non-smoking households. All the analytes were found in the samples, nicotine being the most abundant compound in smokers' dust and one of the most abundant in non-smokers' dust. To our knowledge this is the first time that volatile N-nitrosamines and TSNAs have been determined in indoor dust samples. The results demonstrate the presence of these highly carcinogenic compounds in house dust, with inherent human exposure through inhalation and/or involuntary ingestion of house dust.

Abstract
Despite a major decrease in the incidence of sudden infant death syndrome (SIDS) since the American Academy of Pediatrics (AAP) released its recommendation in 1992 that infants be placed for sleep in a nonprone position, this decline has plateaued in recent years. Concurrently, other causes of sudden unexpected infant death occurring during sleep (sleep-related deaths), including suffocation, asphyxia, and entrapment, and ill-defined or unspecified causes of death have increased in incidence, particularly since the AAP published its last statement on SIDS in 2005. It has become increasingly important to address these other causes of sleep-related infant death. Many of the modifiable and nonmodifiable risk factors for SIDS and suffocation are strikingly similar. The AAP, therefore, is expanding its recommendations from being only SIDS-focused to focusing on a safe sleep environment that can reduce the risk of all sleep-related infant deaths including SIDS. The recommendations described in this report include supine positioning, use of a firm sleep surface, breastfeeding, room-sharing without bed-sharing, routine immunization, consideration of a pacifier, and avoidance of soft bedding, overheating, and exposure to tobacco smoke, alcohol, and illicit drugs. The rationale for these recommendations is discussed in detail in this technical report. The recommendations are published in the accompanying "Policy Statement--Sudden Infant Death Syndrome and Other Sleep-Related Infant Deaths: Expansion of Recommendations for a Safe Infant Sleeping Environment," which is included in this issue (www.pediatrics.org/cgi/doi/10.1542/peds.2011-2220).

Abstract
This work evaluates the characteristics of short-term release of volatile and semi-volatile organic chemicals from clothing fabrics that are exposed to environmental tobacco smoke (ETS). Various fabrics were concurrently exposed to ETS in a controlled facility, and the chemicals off-gassed were sampled using solid phase micro-extraction coupled with GC/MS analysis. Toluene-reference concentration (TRC) was calculated for nine selected chemicals and compared. The number of chemicals identified from ETS-exposed fabrics ranged from 13 (polyester and acetate) to 32 (linen). All fabrics off-gassed formaldehyde, tetradecanoic acid and n-hexadecanoic acid, while seven out of eight fabrics emitted furfural, benzonitrile, naphthalene and decanal. Natural fibers of plant origin (cotton and linen) off-gassed higher concentrations (TRC>100 μg/l) of chemicals that have low molecular weight (~100 or less) than did natural fibers of animal origin (wool and silk) and synthetic fibers. Conversely, wool and silk off-gassed more chemicals that are of high molecular weight (>200), such as TDA (TRC>100 μg/l) and n-HDA (TRC>500 μg/l), than did other fabrics. Fabric structure (for a particular material) significantly affects chemical off-gassing. Cotton typically used for polo shirt (knitted) off-gassed significantly (p<0.05) higher TRC for chemicals with molecular weight of ~100 (such as furfural) than did other cottons of woven style. The dyeing of fabric (white vs. black) had a limited effect on emission, while increasing contact time with ETS increased the intensity of chemical emissions. The mean TRC for cotton exposed for 12 min was nearly doubled than those exposed for 8min, but no difference existed for polyester.

Abstract
BACKGROUND There is broad consensus regarding the health impact of tobacco use and secondhand smoke exposure, yet considerable ambiguity exists about the nature and consequences of thirdhand smoke (THS). OBJECTIVES We introduce definitions of THS and THS exposure and review recent findings about constituents, indoor sorption-desorption dynamics, and transformations of THS; distribution and persistence of THS in residential settings; implications for pathways of exposure; potential clinical significance and health effects; and behavioral and policy issues that affect and are affected by THS. DISCUSSION Physical and chemical transformations of tobacco smoke pollutants take place over time scales ranging from seconds to months and include the creation of secondary pollutants that in some cases are more toxic (e.g., tobacco-specific nitrosamines). THS persists in real-world residential settings in the air, dust, and surfaces and is associated with elevated levels of nicotine on hands and cotinine in urine of nonsmokers residing in homes previously occupied by smokers. Much still needs to be learned about the chemistry, exposure, toxicology, health risks, and policy implications of THS. CONCLUSION The existing evidence on THS provides strong support for pursuing a programmatic research agenda to close gaps in our current understanding of the chemistry, exposure, toxicology, and health effects of THS, as well as its behavioral, economic, and sociocultural considerations and consequences. Such a research agenda is necessary to illuminate the role of THS in existing and future tobacco control efforts to decrease smoking initiation and smoking levels, to increase cessation attempts and sustained cessation, and to reduce the cumulative effects of tobacco use on morbidity and mortality.

Abstract
Worldwide, the burden of suffering to children caused by tobacco does not just originate from exposure to tobacco smoke or smoking, but includes exposure to tobacco-friendly media, poverty associated with money spent on tobacco, increased incidence of tobacco-related fires, and the harms related to child labor in tobacco cultivation. Despite global efforts through human rights acts, the Framework Convention on Tobacco Control, and the MPOWER report, tobacco use continues to accelerate in most countries. While the efforts that have been taken, such as smoking bans in public, are worthy actions, not enough is being done to protect children and teens. More can be done at the policy level, by individuals, and by health care providers.

Abstract
OBJECTIVES Secondhand smoke (SHS) exposure is an important cause of morbidity in children. We assessed the impact of family rules about smoking in the home and car on SHS exposure prevalence in students in grades six to 12. METHODS We studied never-smoking young people (n = 1,698) in the random sample cross-sectional South Carolina Youth Tobacco Survey, a 2006 survey of middle and high school students in South Carolina. RESULTS Overall, 40% of the students reported SHS exposure in either the home or car in the past week; among these, 85% reported exposure in cars. Subsequent analyses focused on students who lived with a smoker (n = 602). Compared with those whose families prohibited smoking in the home or car, SHS exposure prevalence was 30% (p < 0.0001) higher for households with smoke-free rules for only one place (home or car) and 36% (p < 0.0001) higher for households with no rules. Compared with students from households with strict rules, SHS exposure prevalence was 48% greater (p < 0.0001) among those with only partial rules against smoking in the home or car, and 55% (p < 0.0001) greater among those from households with no rules. Similarly, compared with students with strict family rules for home and car that were adhered to, SHS exposure prevalence was significantly higher (p < 0.0001) among students when only one or no rules were followed. CONCLUSIONS Young people from families that made and enforced strong rules against smoking in homes and cars were much less likely to report SHS exposure. Parents would be wise to endorse and enforce strong smoke-free policies for both homes and cars.

Abstract
BACKGROUND Home smoking bans significantly reduce the likelihood of secondhand smoke exposure among children and non-smoking adults. The purpose of this study was to examine national trends in (1) the adoption of home smoking bans, (2) discrepancies in parental smoking ban reports and (3) household and parental correlates of home smoking bans among households with underage children from 1995 to 2007. METHODS The authors used data from the 1995-1996, 1998-1999, 2001-2002, 2003 and 2006-2007 Tobacco Use Supplement of the US Current Population Survey to estimate prevalence rates and logistic regression models of parental smoking ban reports by survey period. RESULTS Overall, the prevalence of a complete home smoking bans increased from 58.1% to 83.8% (p<0.01), while discrepancies in parental reports decreased from 12.5% to 4.6% (p<0.01) from 1995 to 2007. Households with single parent, low income, one or two current smokers, parents with less than a college education or without infants were consistently less likely to report a home smoking ban over this period (p<0.05). CONCLUSIONS Despite general improvements in the adoption of home smoking bans and a reduction on parental discrepancies, disparities in the level of protection from secondhand smoke have persisted over time. Children living in households with single parents, low income, current smoker parents, less educated parents or without infants are less likely to be protected by a home smoking ban. These groups are in need of interventions promoting the adoption of home smoking bans to reduce disparities in tobacco-related diseases.

Abstract
OBJECTIVE To examine selected social determinants of a home smoking policy among US households with children and whether these associations vary by the presence of a smoker and children's ages. METHODS In the 2006/2007 US Tobacco Use Supplement to the Current Population Survey there were 30,874 parents with 0-17-year-olds. RESULTS 83.9% of parents reported that no one was allowed to smoke inside the home. However, a no smoking policy varied by the presence of a smoker (93.6% of non-smoking households; 55.8% of smoking households) and children's ages (87.1% of parents with any 0-5-year-olds; 82.1% with 6-17-year-olds only; 79.2% with 14-17-year-olds only). In smoking and non-smoking households, parents of 6-17-year-olds were 25%-46% less likely to have a no smoking policy than parents of younger children. Among smoking households, Hispanic and Asian parents were over twice as likely to not allow smoking inside the home as white parents, while Black parents were half as likely. Parents from more disadvantaged circumstances were less likely to have a no smoking policy. CONCLUSIONS Parents of 6-17-year-olds are less likely to have a no smoking policy than parents of younger children. Parents with children of all ages should enact a smoking policy that promotes a smoke-free home.

Abstract
The underlying mechanisms and effector molecules involved in mediating in utero smoke exposure-induced effects on the developing lung are only beginning to be understood. However, the effects of a newly discovered category of smoke, i.e., thirdhand smoke (THS), on the developing lung are completely unknown. We hypothesized that, in addition to nicotine, other components of THS would also affect lung development adversely. Fetal rat lung explants were exposed to nicotine, 1-(N-methyl-N-nitrosamino)-1-(3-pyridinyl)-4-butanal (NNA), or 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK), the two main tobacco-specific N-nitrosamine constituents of THS, for 24 h. We then determined key markers for alveolar paracrine signaling [epithelial differentiation markers surfactant phospholipid and protein synthesis; mesenchymal differentiation markers peroxisome proliferator-activated receptor γ (PPAR-γ), fibronectin and calponin], the BCL-2-to-Bax ratio (BCL-2/Bax), a marker of apoptosis and the involvement of nicotinic acetylcholine receptors (nAChR)-α3 and -α7 in mediating NNA's and NNK's effects on the developing lung. Similar to the effects of nicotine, exposure of the developing lung to either NNK or NNA resulted in disrupted homeostatic signaling, indicated by the downregulation of PPAR-γ, upregulation of fibronectin and calponin protein levels, decreased BCL-2/Bax, and the accompanying compensatory stimulation of surfactant phospholipid and protein synthesis. Furthermore, nAChR-α3 and -α7 had differential complex roles in mediating these effects. NNK and NNA exposure resulted in breakdown of alveolar epithelial-mesenchymal cross-talk, reflecting lipofibroblast-to-myofibroblast transdifferentiation, suggesting THS constituents as possible novel contributors to in utero smoke exposure-induced pulmonary damage. These data are particularly relevant for designing specific therapeutic strategies, and for formulating public health policies to minimize THS exposure.

Abstract
BACKGROUND Tobacco smoke exposure (TSE) is a serious threat to child health. Roughly 40% of children worldwide are exposed to tobacco smoke, and the very young are often "captive smokers" in homes in which others smoke.The goal of this research project is to develop and evaluate an intervention to reduce young child tobacco smoke exposure. The objective of this paper is to document our approach to building the intervention, to describe the planned intervention, and to explore the conceptual issues regarding the intervention and its evaluation. METHODS/DESIGN This project is being developed using an iterative approach. We are currently in the middle of Stage 1. In this first stage, Intervention Development, we have already conducted a comprehensive search of the professional literature and internet resources, consulted with experts in the field, and conducted several Design Workshops. The planned intervention consists of parental group support therapy, a website to allow use of an "online/offline" approach, involvement of pediatricians, use of a video simulation game ("Dr. Cruz") to teach parents about child TSE, and personalized biochemical feedback on exposure levels. As part of this stage we will draw on a social marketing approach. We plan to use in-depth interviews and focus groups in order to identify barriers for behavior change, and to test the acceptability of program components.In Stage II, we plan to pilot the planned intervention with 5-10 groups of 10 parents each.In Stage III, we plan to implement and evaluate the intervention using a cluster randomized controlled trial with an estimated 540 participants. DISCUSSION The major challenges in this research are twofold: building an effective intervention and measuring the effects of the intervention. Creation of an effective intervention to protect children from TSE is a challenging but sorely needed public health endeavor. We hope that our approach will contribute to building a stronger evidence base for control of child exposure to tobacco smoke.

Abstract
Background Children's exposure to secondhand smoke is associated with increased morbidity. We estimated Medicaid expenditures for children living with smokers compared to those living with no smokers in the United States. Methods Data were overall and service-specific (i.e., inpatient, ambulatory, emergency department, prescription drug, and dental) annual Medicaid expenditures for children 0-11 years old from the 2000-2007 Medical Expenditures Panel Surveys. Smokers' presence in households was determined by adult respondents' self reports. There were 25,835 person-years of observation. We used multivariate analyses to adjust for child, parent, and geographic characteristics. Results Children with Medicaid expenditures were nearly twice as likely to live with a smoker as other children in the U.S. population. Adjusted analyses revealed no detectable differences in children's overall Medicaid expenditures by presence of smokers in the household. Medicaid children who lived with smokers on average had $10 (95% CI $3, $18) higher emergency department expenditures per year than those living with no smokers. Conclusions Living with at least one smoker (a proxy for secondhand smoke exposure) is unrelated to children's overall short-term Medicaid expenditures, but has a modest impact on emergency department expenditures. Additional research is necessary to understand the relationship between secondhand smoke exposure and long-term health and economic outcomes.

Abstract
BACKGROUND The environment is suspected to play an important role in the development of childhood asthma. Cohort studies are a powerful observational design for studying exposure-response relationships, but their power depends in part upon the accuracy of the exposure assessment. OBJECTIVE The purpose of this paper is to summarize and discuss issues that make accurate exposure assessment a challenge and to suggest strategies for improving exposure assessment in longitudinal cohort studies of childhood asthma and allergies. DATA SYNTHESIS Exposures of interest need to be prioritized, because a single study cannot measure all potentially relevant exposures. Hypotheses need to be based on proposed mechanisms, critical time windows for effects, prior knowledge of physical, physiologic, and immunologic development, as well as genetic pathways potentially influenced by the exposures. Modifiable exposures are most important from the public health perspective. Given the interest in evaluating gene-environment interactions, large cohort sizes are required, and planning for data pooling across independent studies is critical. Collection of additional samples, possibly through subject participation, will permit secondary analyses. Models combining air quality, environmental, and dose data provide exposure estimates across large cohorts but can still be improved. CONCLUSIONS Exposure is best characterized through a combination of information sources. Improving exposure assessment is critical for reducing measurement error and increasing power, which increase confidence in characterization of children at risk, leading to improved health outcomes.

Abstract
BACKGROUND People exposed to secondhand tobacco smoke (SHS) inhale the lung carcinogen 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK) which is metabolized to NNAL and its glucuroniders. These urinary metabolites, termed total NNAL, can be quantified. A related compound, iso-NNAL, has been proposed as a biomarker for exposure to smoke constituent residues on surfaces (thirdhand tobacco smoke). There is limited information in the literature on levels of total NNAL in children exposed to SHS. METHODS We recruited 79 parent--child dyads from homes where the enrolled parent was a cigarette smoker and visited their homes. Parents were asked questions, home ambient air quality was evaluated, and children provided urine samples. Urine was analyzed for total NNAL, total cotinine, total nicotine, and iso-NNAL. RESULTS Ninety percent of the children had detectable total NNAL in urine; total nicotine and total cotinine were also detected in most samples. There were significant positive relationships between biomarker levels and exposure of children in the home. Levels were highest in homes with no smoking restrictions. African American children had significantly higher levels than other children. iso-NNAL was not detected in any urine sample. CONCLUSIONS There was nearly universal exposure of children to the lung carcinogen NNK, due mainly to exposure to SHS from adult smokers in their homes. IMPACT Homes with adult smokers should adopt restrictions to protect their children from exposure to a potent lung carcinogen.

Abstract
BACKGROUND Tests are available to measure children's exposure to tobacco smoke. One potential barrier to testing children for tobacco-smoke exposure is the belief that parents who smoke would not want their child tested. No previous surveys have assessed whether testing children for exposure to tobacco smoke in the context of their child's primary care visit is acceptable to parents. OBJECTIVE To assess whether testing children for tobacco-smoke exposure is acceptable to parents. DESIGN AND METHODS We conducted a national random-digit-dial telephone survey of households from September to November 2006. The sample was weighted by race and gender, based on the 2005 US Census, to be representative of the US population. RESULTS Of 2070 eligible respondents contacted, 1803 (87.1%) completed the surveys. Among 477 parents in the sample, 60.1% thought that children should be tested for tobacco-smoke exposure at their child's doctor visit. Among the parental smokers sampled, 62.0% thought that children should be tested for tobacco-smoke exposure at the child's doctor visit. In bivariate analysis, lower parental education level, allowing smoking in the home, nonwhite race, and female gender were each associated (P < .05) with wanting the child tested for tobacco-smoke exposure. CONCLUSIONS The majority of nonsmoking and smoking parents want their children tested for tobacco-smoke exposure during the child's health care visit.

Abstract
PRIMARY CARE PROVIDERS SHOULD BE AWARE OF TWO NEW DEVELOPMENTS IN NICOTINE ADDICTION AND SMOKING CESSATION: 1) the emergence of a novel nicotine delivery system known as the electronic (e-) cigarette; and 2) new reports of residual environmental nicotine and other biopersistent toxicants found in cigarette smoke, recently described as "thirdhand smoke". The purpose of this article is to provide a clinician-friendly introduction to these two emerging issues so that clinicians are well prepared to counsel smokers about newly recognized health concerns relevant to tobacco use. E-cigarettes are battery powered devices that convert nicotine into a vapor that can be inhaled. The World Health Organization has termed these devices electronic nicotine delivery systems (ENDS). The vapors from ENDS are complex mixtures of chemicals, not pure nicotine. It is unknown whether inhalation of the complex mixture of chemicals found in ENDS vapors is safe. There is no evidence that e-cigarettes are effective treatment for nicotine addiction. ENDS are not approved as smoking cessation devices. Primary care givers should anticipate being questioned by patients about the advisability of using e-cigarettes as a smoking cessation device. The term thirdhand smoke first appeared in the medical literature in 2009 when investigators introduced the term to describe residual tobacco smoke contamination that remains after the cigarette is extinguished. Thirdhand smoke is a hazardous exposure resulting from cigarette smoke residue that accumulates in cars, homes, and other indoor spaces. Tobacco-derived toxicants can react to form potent cancer causing compounds. Exposure to thirdhand smoke can occur through the skin, by breathing, and by ingestion long after smoke has cleared from a room. Counseling patients about the hazards of thirdhand smoke may provide additional motivation to quit smoking.

Abstract
BACKGROUND Second hand smoke (SHS) exposure has long been correlated with many adverse disease processes, particularly in children. For children growing up with socioeconomic disadvantages and increased exposure to SHS, exposure can have far-reaching consequences. OBJECTIVE The purpose of this review was to examine the literature assessing the effects of SHS exposure in children, as well as the perspectives of both parents and providers regarding current practices in cessation counseling. The review also sought out recommendations on ways to increase the influence of pediatricians on parental smoking. STUDY GROUP Children under the age of 18 years. METHODS PubMed and MEDLINE were searched systematically. A narrative approach was used because the studies differed in methods and data. RESULTS The studies showed correlations between SHS exposure and sudden infant death syndrome (SIDS), asthma, altered respiratory function, infection, cardiovascular effects, behavior problems, sleep difficulties, increased cancer risk, and a higher likelihood of smoking initiation. Questionnaires of both parents and pediatricians showed that pediatricians are not consistently carrying out the recommended smoking cessation interventions, with lack of training as a primary barrier. Nevertheless, interventions targeting improved cessation training for both residents and practicing pediatricians have been studied and show promising results. CONCLUSIONS SHS exposure has many detrimental effects on children's health, particularly for those in low socioeconomic circumstances, for which factors in the built environment accentuated a higher baseline risk. By counseling parents, expanding residency education, and continuing advocacy work, pediatricians can have a significant positive impact on children's health as related to SHS exposure.

Abstract
OBJECTIVE There is no safe level of secondhand tobacco-smoke exposure, and no previous studies have explored multiunit housing as a potential contributor to secondhand tobacco-smoke exposure in children. We hypothesized that children who live in apartments have higher cotinine levels than those who live in detached homes, when controlling for demographics. METHODS We analyzed data from the 2001-2006 National Health and Nutrition Examination Survey. The housing types we included in our study were detached houses (including mobile homes), attached houses, and apartments. Our study subjects were children between the ages of 6 and 18 years. Cotinine levels were used to assess secondhand tobacco-smoke exposure, and those living with someone who smoked inside the home were excluded. χ(2) tests, t tests, and Tobit regression models were used in Stata. Sample weights accounted for the complex survey design. RESULTS Of 5002 children in our study, 73% were exposed to secondhand tobacco smoke. Children living in apartments had an increase in cotinine of 45% over those living in detached houses. This increase was 212% (P < .01) for white residents and 46% (P < .03) for black residents, but there was no significant increase for those of other races/ethnicities. At every cutoff level of cotinine, children in apartments had higher rates of exposure. The exposure effect of housing type was most pronounced at lower levels of cotinine. CONCLUSIONS Most children without known secondhand tobacco-smoke exposure inside the home still showed evidence of tobacco-smoke exposure. Children in apartments had higher mean cotinine levels than children in detached houses. Potential causes for this result could be seepage through walls or shared ventilation systems. Smoking bans in multiunit housing may reduce children's exposure to tobacco smoke.

Abstract
Tobacco smoking is well-known as a significant source of primary indoor air pollutants. However, only recently has thirdhand smoke (THS) been recognized as a contributor to indoor pollution due to the role of indoor surfaces. Here, the effects of relative humidity (<10% RH and ∼ 45% RH) and substrate (cellulose, cotton, and paper) on secondary organic aerosol (SOA) formation from nicotine-ozone-NO(x) reactions are discussed. SOA formation from the sorbed nicotine-ozone reaction ([O(3)] = 55 ppb) varied in size distribution and number, depending on RH and substrate type, indicating the role of substrate and water interactions in SOA formation. This led to SOA yields from cellulose sorbed nicotine-ozone reaction of ∼ 1 and 2% for wet and dry conditions, respectively. SOA formation from nicotine-NO(x) reactions was not distinguishable from background levels. Simultaneously, cellulose sorbed nicotine-ozone reaction kinetics ([O(3)] = 55 ppb) were obtained and revealed pseudofirst-order surface rate constants of k(1) = (1 ± 0. 5) × 10(-3) and k(1) < 10(-4) min(-1) under <10% and ∼ 45% RH, respectively. Given the toxicity of some of the identified products and that small particles may contribute to adverse health effects, the present study indicates that exposure to THS ozonation products may pose additional health risks.

Abstract
DNA adducts play a central role in chemical carcinogenesis. The analysis of formation and repair of smoking-related DNA adducts remains particularly challenging as both smokers and nonsmokers exposed to smoke are repetitively under attack from complex mixtures of carcinogens such as polycyclic aromatic hydrocarbons and N-nitrosamines. The bulky DNA adducts, which usually have complex structure, are particularly important because of their biological relevance. Several known cellular DNA repair pathways have been known to operate in human cells on specific types of bulky DNA adducts, for example, nucleotide excision repair, base excision repair, and direct reversal involving O6-alkylguanine DNA alkyltransferase or AlkB homologs. Understanding the mechanisms of adduct formation and repair processes is critical for the assessment of cancer risk resulting from exposure to cigarette smoke, and ultimately for developing strategies of cancer prevention. This paper highlights the recent progress made in the areas concerning formation and repair of bulky DNA adducts in the context of tobacco carcinogen-associated genotoxic and carcinogenic effects.

Abstract
BACKGROUND Exposure to secondhand smoke (SHS) is a contributor to the increased morbidity and mortality experienced by inner-city African-American children. Limited evidence-based programming exists regarding how to address the negative effects of SHS in this community. PURPOSE A collaboration with an early child care center provided an opportunity to explore factors related to young children's SHS exposure as the first step in developing strategies to reduce exposure. METHODS Survey data were obtained between 2008 and 2009 from 63 African-American parents of infants and children aged ≤ 5 years at two early child care centers located in an urban Minneapolis neighborhood. Forty-three of these children had salivary cotinine levels assessed. RESULTS Parents living below the poverty level were more likely to report that their children were regularly exposed to SHS by family/friends (p = 0.01). Sixty-eight percent of participants reported complete home smoking restrictions, which was significantly correlated with advice from the child's health provider (p = 0.001). Nonsmokers and older parents were less likely to receive advice (p = 0.03). Of the 43 children in whom cotinine levels were assessed, 39.5% had levels > 0.64 ng/ml, which suggests high SHS exposure. Lower cotinine levels were significantly correlated with living in detached houses. CONCLUSIONS Exposure to SHS was common for children in this study. These findings, if supported by additional research, can be used to develop and disseminate targeted health messages about childhood SHS sources/negative effects and strategies to reduce exposure.

Abstract
OBJECTIVE Genes and environment are the main determinants of cardiovascular disease (CVD) risk factor clustering in families. Since individual risk factor profiles are easily predicted within families, we examined whether CVD risk factors are affected by lifestyle factors in these families. METHODS Nutrition, physical activity, and smoking habits were assessed in 2001 biological child-parent pairs from 852 families participating in the Prevention Education Program (PEP). Height, weight, body mass index, waist circumference, blood pressure, and fasting lipid levels were measured. Within-family associations were calculated using generalized estimating equations (GEE). RESULTS Fathers possessed the most adverse risk profile. Daily energy consumption above the recommended levels was higher in children (daughters +35.4%, sons +26.7%) than in parents (fathers +15.7%, mothers +10.6%). Higher energy consumption was significantly associated with hypertension in mothers (OR 2.5) and in fathers (OR 1.7). Hyper-caloric nutrition of the parents predicted the energy intake of the children in: mother-daughter (OR 7.5), mother-son (OR 3.0), and father-son (OR 2.8) pairs. Low mono-unsaturated fatty acid intake was significantly associated with a high LDL/HDL-C ratio (OR 3.4) and hypertriglyceridemia (OR 2.2) in fathers. Approximately 25% of parents and children reported at least two physical activities twice a week. The 23% of children who were passive smokers presented a far more adverse risk profile than children without exposure to second-hand smoke. CONCLUSION Intergenerational lifestyle habits affect cardiovascular risk factors within biological families. As lifestyle habits are predictable, they may be used for implementation of family-based CVD prevention strategies.

Abstract
INTRODUCTION This study, informed by ecological frameworks, compared the prevalence, predictors, and association of home smoking restrictions with secondhand smoke exposure (SHSe) between Koreans in Seoul, South Korea, and Korean Americans in California, United States. METHODS A cross-sectional survey was drawn from telephone interviews with Korean adults in Seoul (N = 500) and California (N = 2,830) during 2001-02. Multivariable regressions were used for analyses. RESULTS Koreans, compared with Korean Americans, had significantly fewer complete home smoking bans, 19% (95% CI: 16-23) versus 66% (95% CI: 64-68), and were more likely to not have a home smoking restriction, 64% (95% CI: 60-69) versus 5% (95% CI: 4-6). Home smoking restrictions were associated with lower home SHSe; however, the impact was consistently larger among Korean Americans. Households with more SHSe sources were less likely to have the strongest home smoking restrictions, where the difference in complete bans among Korean Americans versus Koreans was largely among those at low risk of SHSe, 82% (95% CI: 76-86) versus 36% (95% CI: 17-57), while high-risk Korean American and Koreans had similar low probabilities, 10% (95% CI: 7-13) versus 7% (95% CI: 3-13). CONCLUSIONS Consistent with ecological frameworks, exposure to California's antismoking policy and culture was associated with stronger home smoking restrictions and improved effectiveness. Interventions tailored to Korean and Korean American SHSe profiles are needed. Behavioral interventions specifically for high-risk Korean Americans and stronger policy controls for Koreans may be effective at rapidly expanding home smoking restrictions.

Abstract
INTRODUCTION Smoking cigarettes in the enclosed environment of a car leads to the contamination of a car's microenvironment with residual tobacco smoke pollution (TSP). METHODS Surface wipe, air, and dust samples were collected in used cars sold by nonsmokers (n = 40) and smokers (n = 87) and analyzed for nicotine. Primary drivers were interviewed about smoking behavior and restrictions, and car interiors were inspected to investigate (a) differences in car dustiness, signs of past smoking, ventilation use, mileage, and passenger cabin volume among nonsmokers and smokers with and without in-car smoking bans and (b) factors that contribute to the contamination of cars with residual TSP, such as ventilation use, cleaning behaviors, signs of past smoking, and holding the cigarette near/outside the car window while smoking. RESULTS Smokers reported using air conditioning less (p < .05) and driving with windows down more often than nonsmokers (p = .05); their cars were also dustier (p < .01) and exhibited more ash and burn marks than nonsmokers' cars (p < .001). Number of cigarettes smoked by the primary driver was the strongest predictor of residual TSP indicators (R(2) = .10 - .16, p = .001). This relationship was neither mediated by ash or burn marks nor moderated by efforts to remove residual TSP from the vehicle (i.e., cleaning, ventilation) or attempts to prevent tobacco smoke pollutants from adsorbing while smoking (e.g., holding the cigarette near/outside window). DISCUSSION Findings suggest that smokers can prevent their cars from becoming contaminated with residual TSP by reducing or ceasing smoking; however, commonly used cleaning and ventilation methods did not successfully decrease contamination levels. Disclosure requirements and smoke-free certifications could help protect buyers of used cars and empower them to request nonsmoking environments or a discount on cars that have been smoked in previously.

Abstract
Impoverished children suffer disproportionately from asthma and are more likely than other children to be exposed to secondhand smoke (SHS). We conducted a case-control study to describe and compare knowledge, attitudes, and household practices regarding SHS exposure among parents of young urban children with and without asthma (response rate, 76%). Overall, 39% of children lived with > or =1 smoker (cases, 36%; controls, 43%). The majority of parents (78%) felt that cigarette smoking is very dangerous and agreed that smoke harms the health of children (97%). Cases were more likely than controls to report that smoking in a car affects children's health (54% vs 42%) and that smoking in front of children is never allowed in their home (88% vs 79%). Additionally, more cases reported a home smoking ban (81% vs 70%). Our findings suggest that parents of children with asthma have somewhat better knowledge, attitudes, and practices regarding SHS; however, gaps remain, and many urban children continue to be exposed.

Abstract
This study shows that residual nicotine from tobacco smoke sorbed to indoor surfaces reacts with ambient nitrous acid (HONO) to form carcinogenic tobacco-specific nitrosamines (TSNAs). Substantial levels of TSNAs were measured on surfaces inside a smoker's vehicle. Laboratory experiments using cellulose as a model indoor material yielded a > 10-fold increase of surface-bound TSNAs when sorbed secondhand smoke was exposed to 60 ppbv HONO for 3 hours. In both cases we identified 1-(N-methyl-N-nitrosamino)-1-(3-pyridinyl)-4-butanal, a TSNA absent in freshly emitted tobacco smoke, as the major product. The potent carcinogens 4-(methylnitrosamino)-1-(3-pyridinyl)-1-butanone and N-nitroso nornicotine were also detected. Time-course measurements revealed fast TSNA formation, with up to 0.4% conversion of nicotine. Given the rapid sorption and persistence of high levels of nicotine on indoor surfaces-including clothing and human skin-this recently identified process represents an unappreciated health hazard through dermal exposure, dust inhalation, and ingestion. These findings raise concerns about exposures to the tobacco smoke residue that has been recently dubbed "thirdhand smoke." Our work highlights the importance of reactions at indoor interfaces, particularly those involving amines and NO(x)/HONO cycling, with potential health impacts.

Abstract
OBJECTIVE An analysis of airborne nicotine measurements collected in 49 low-income, multi-unit residences across the Greater Boston Area. METHODS Nicotine concentrations were determined using passive monitors placed in homes over a one-week sampling period and air exchange rates (AER) were sampled using the perfluorocarbon tracer technique. Residents were surveyed through a questionnaire about smoking behaviour and a visual inspection was conducted to collect information on housing characteristics contributing to secondhand smoke (SHS) exposure. Using a mass balance model to account for the air exchange rate, volume of the home and sorption and re-emission of nicotine on indoor surfaces, the effective smoking rate (SR(eff)) was determined for each residence. RESULTS Nicotine levels ranged from the limit of detection to 26.92 microg/m(3), with a mean of 2.20 microg/m(3) and median of 0.13 microg/m(3). Nicotine measurements were significantly associated with the number of smokers in the household and the number of cigarettes smoked in the home. The results of this study suggest that questionnaire reports can provide a valid estimate of residential exposure to tobacco smoke. In addition, this study found evidence that tobacco smoke contamination in low-income housing developments is not limited to homes with smokers (either residing in the home or visiting). The frequent report of tobacco smoke odour coming from other apartments or hallways resulted in increased levels of nicotine concentrations and SR(eff) in non-smoking homes, suggestive of SHS infiltration from neighbouring units. CONCLUSION These findings have important implications for smoking regulations in multi-unit homes and highlight the need to reduce involuntary exposure to tobacco smoke among low-income housing residents.

Abstract
INTRODUCTION This article outlines a theoretical framework for research concerning secondhand smoke exposure (SHSe) prevention as a means to curtail the tobacco industry. METHODS The Behavioral Ecological Model (BEM) assumes interlocking social contingencies of reinforcement (i.e., rewards or punishments) from the highest level of society (e.g., taxing cigarette sales) to physiological reactions to nicotine that influence smoking and SHSe. We review selected research concerning both policy and clinical efforts to restrict smoking and/or SHSe. RESULTS Research to date has focused on smoking cessation with modest to weak effects. The BEM and empirical evidence suggest that cultural contingencies of reinforcement should be emphasized to protect people from SHSe, especially vulnerable children, pregnant women, the ill, the elderly, and low-income adults who have not "elected" to smoke. Doing so will protect vulnerable populations from industry-produced SHSe and may yield more and longer-lasting cessation. CONCLUSIONS Interventions that reduce SHSe may serve as a Trojan horse to counter the tobacco industry. Future studies should: (a) guide policies to restrict SHSe; (b) develop powerful community and clinical interventions to reduce SHSe; (c) test the degree to which policies and other contexts enhance the effects of clinical interventions (e.g., media programs disclosing the disingenuous marketing by the industry); and (d) investigate the effects of all health care providers' ability to reduce SHSe and generate an antitobacco culture, by advising all clients to avoid starting to smoke, to protect their children from SHSe, and to quit smoking.

Abstract
OBJECTIVE: To discuss strategies for integrating evidence-based tobacco use screening, cessation assistance, and referral to outside services into visits with families in outpatient child health care settings. METHODS: Presentation of counseling scenarios used in the Clinical Effort Against Secondhand Smoke Exposure (CEASE) training video and commentary. RESULTS: Demonstrated strategies include: eliciting information about interest and readiness to quit smoking, respectfully setting an agenda to discuss smoking, tailoring advice and education to the specific circumstances, keeping the dialogue open, prescribing cessation medication, helping the smoker set an action plan for cessation, enrolling the smoker in free telephone counseling through the state quitline, and working with family members to establish a completely smoke-free home and car. Video demonstrations of these techniques are available at www.ceasetobacco.org. CONCLUSION: Child health care clinicians have a unique opportunity to address family smoking and can be most effective by adapting evidence-based tobacco cessation counseling strategies for visits in the pediatric setting.

Abstract
The atherogenic effect of cigarette smoking is already recognizable in coronary arteries of fetuses in the last gestational weeks. In this study we analyzed the atherogenic effect of mother's and father's smoking habit on coronary arteries and even on adnexa of 30 human fresh fetuses died from 32 to 41 gestational weeks. In 12 cases only the mothers of the victims were cigarette smokers, in 7 cases only the fathers were smokers, whereas in 11 cases nobody smoked.We observed pre-atherosclerotic and initial atherosclerotic lesions of the adnexa in 21 cases, of which 11 cases had only mother smokers and 6 cases only father smokers. The atherogenic effect is statistically significant in both smoker groups, but stronger in maternal one. The atherosclerotic lesions found in umbilical and placental arteries are similar to those described in fetal coronary arteries: thickening of the arterial walls caused by proliferation and migration of the smooth muscle cells of the tunica media with loss of polarity and infiltration of the subendothelial connective tissue.

Abstract
Hookah (narghile, shisha, "water-pipe") smoking is now seen by public health officials as a global tobacco epidemic. Cigarette Environmental Tobacco Smoke (ETS) is classically understood as a combination of Side-Stream Smoke (SSS) and Exhaled Main-Stream Smoke (EMSS), both diluted and aged. Some of the corresponding cigarette studies have served as the scientific basis for stringent legislation on indoor smoking across the world. Interestingly, one of the distinctive traits of the hookah device is that it generates almost no SSS. Indeed, its ETS is made up almost exclusively by the smoke exhaled by the smoker (EMSS), i.e. which has been filtered by the hookah at the level of the bowl, inside the water, along the hose and then by the smoker's respiratory tract itself. The present paper reviews the sparse and scattered scientific evidence available about hookah EMSS and the corresponding inferences that can be drawn from the composition of cigarette EMSS. The reviewed literature shows that most of hookah ETS is made up of EMSS and that the latter qualitatively differs from MSS. Keeping in mind that the first victim of passive smoking is the active smoker her/himself, the toxicity of hookah ETS for non-smokers should not be overestimated and hyped in an unscientific way.
