Disparities and Trends in Indoor Exposure to Secondhand Smoke among U.S. Adolescents: 2000-2009
Introduction: Secondhand smoke (SHS) exposure causes disease and death among nonsmokers. With a plethora of smoke-free legislation implemented and a steady decrease in cigarette consumption noted over the past decade in the U.S., this study assessed trends in indoor SHS exposure among U.S. adolescents in grades 6â12 during 2000â2009. Methods: Data were obtained from the 2000â2009 National Youth Tobacco Survey â a national survey of U.S. middle and high school students. SHS exposure within an indoor area within the past seven days was self-reported. Trends in indoor SHS exposure during 2000â2009 were assessed overall and by socio-demographic characteristics, using the Wald's test in a binary logistic regression. Within-group comparisons were performed using chi-squared statistics (p<0.05). Results: The proportion of U.S. middle and high school students who were exposed to indoor SHS declined from 65.5% in 2000 to 40.5% in 2009 (p<0.05 for linear trend). Significant declines were also observed across all population subgroups. Between 2000 and 2009, prevalence of indoor SHS exposure declined significantly among both middle (58.5% to 34.3%) and high school (71.5% to 45.4%) students. Prevalence of indoor SHS exposure was significantly higher among girls (44.0% in 2009) compared to boys (37.2% in 2009) during each survey year. Similarly, prevalence of indoor SHS exposure during 2000â2009 was highest among non-Hispanic whites (44.2% in 2009) and lowest among non-Hispanic Asians (30.2% in 2009). During each survey year, prevalence was highest among the oldest age group (â„18 years) and lowest among the youngest (9â11 years). Also, prevalence was significantly higher among current cigarette smokers (83.8% in 2009) compared to nonsmokers (34.0% in 2009). Conclusion: Significant declines in indoor SHS exposure among U.S. middle and high school students occurred during 2000â2009. While the results are encouraging, additional efforts are needed to further reduce youth indoor SHS exposure
Prevalence and determinants of cigarette smoking relapse among US adult smokers: a longitudinal study
Objectives This research project aims at estimating the prevalence of cigarette smoking relapse and determining its predictors among adult former smokers in the USA. Setting This research analysed secondary data retrieved from the Tobacco Use Supplement-Current Population Survey 2010â2011 cohort in the USA. Participants Out of 18 499 participants who responded to the survey in 2010 and 2011, the analysis included a total sample size of 3258 ever smokers, who were living in the USA and reported quitting smoking in 2010. The surveyâs respondents who never smoked or reported current smoking in 2010 were excluded from the study sample. Primary and secondary outcome measures Smoking relapse was defined as picking up smoking in 2011 after reporting smoking abstinence in 2010. The prevalence of relapse over the 12-month follow-up period was estimated among different subgroups. Multivariable logistic regression models were applied to determine factors associated with relapse. Results A total of 184 former smokers reported smoking relapse by 2011 (weighted prevalence 6.8%; 95% CI 5.7% to 8.1%). Prevalence and odds of relapse were higher among young people compared with elders. Former smokers living in smoke-free homes (SFHs) had 60% lower odds of relapse compared with those living in homes that allowed smoking inside (adjusted OR 0.40; 95% CI 0.25 to 0.64). Regarding race/ethnicity, only Hispanics showed significantly higher odds of relapse compared with Whites (non-Hispanics). Odds of relapse were higher among never married, widowed, divorced and separated individuals, compared with the married group. Continuous smoking cessation for 6 months or more significantly decreased odds of relapse. Conclusions Wider health determinants, such as race and age, but also living in SFHs showed significant associations with smoking relapse, which could inform the development of more targeted programmes to support those smokers who successfully quit, although further longitudinal studies are required to confirm our findings
Association between unmet dental needs and school absenteeism because of illness or injury among U.S. school children and adolescents aged 6-17 years, 2011-2012
BACKGROUND : We assessed the prevalence of dental disease among U.S. children and adolescents aged 6â17
years, as well as the impact of unmet dental needs on school absenteeism because of illness/injury within the
past 12 months.
METHODS : Data were from the 2011/2012 National Survey of Children's Health (n = 65,680). Unmet dental
need was defined as lack of access to appropriate and timely preventive or therapeutic dental healthcare when
needed within the past 12 months. The impact of unmet dental needs on school absenteeism was measured
using a multivariate generalized linear model with Poisson probability distribution (p b 0.05).
RESULTS : Within the past 12 months, 21.8% (10.8 million) of all U.S. children and adolescents aged 6â17 years
had âa toothache, decayed teeth, or unfilled cavities.â Of all U.S. children and adolescents aged 6â17 years, 15.8%
(7.8 million) reported any unmet dental need (i.e., preventive and/or therapeutic dental need)within the past 12
months. The mean number of days of school absence because of illness/injury was higher among students with
an unmet therapeutic dental need in the presence of a dental condition compared to those reporting no unmet
dental need (ÎČ=0.25; p b 0.001).
CONCLUSIONS : Enhanced and sustained efforts are needed to increase access to dental services among underserved
U.S. children and adolescents.http://www.elsevier.com/locate/ypmed2016-03-31hb201
Tobacco taxation: the importance of earmarking the revenue to health care and tobacco control
Systematic review of outbreaks of COVID-19 within households in the European region when the child is the index case
ObjectivesThis systematic review aims to identify the secondary attack rates (SAR) to adults and other children when children are the index cases within household settings.MethodsThis literature review assessed European-based studies published in Medline and Embase between January 2020 and January 2022 that assessed the secondary transmission of SARS-CoV-2 within household settings. The inclusion criteria were based on the Population, Exposure, Outcome framework for systematic reviews. Thus, the study population was restricted to humans within the household setting in Europe (population), in contact with paediatric index cases 1-17 years old (exposure) that led to the transmission of SARS-CoV-2 reported as either an SAR or the probability of onward infection (outcome).ResultsOf 1819 studies originally identified, 19 met the inclusion criteria. Overall, the SAR ranged from 13% to 75% in 15 studies, while there was no evidence of secondary transmission from children to other household members in one study. Evidence indicated that asymptomatic SARS-CoV-2 index cases also have a lower SAR than those with symptoms and that younger children may have a lower SAR than adolescents (>12 years old) within household settings.ConclusionsSARS-CoV-2 secondary transmission from paediatric index cases ranged from 0% to 75%, within household settings between January 2020 and January 2022, with differences noted by age and by symptomatic/asymptomatic status of the index case. Given the anticipated endemic circulation of SARS-CoV-2, continued monitoring and assessment of household transmission is necessary

Ashtrays and Signage as Determinants of a Smoke-Free Legislationâs Success
Introduction: Successful smoke-free legislation is dependent on political will, enforcement and societal support. We report the success and pitfalls of a non-enforced nationwide smoke-free legislation in Greece, as well as ways in which compliance and enforcement-related factors, including ashtrays and signage, may impact indoor secondhand smoke (SHS) concentrations. Methods: A follow-up study of venues (n = 150, at baseline, n = 75 at 2-year follow-up) in Greece assessed indoor particulate matter with a diameter less than 2.5 micrometers (PM2.5) concentrations attributable to SHS smoke every six months for two years (n = 455 venue/measurements). Results: Following the implementation of the 2010 smoke-free legislation, mean PM2.5 concentrations attributable to SHS fell from 175.3 ”g/m3 pre-ban to 84.52 ”g/m3 immediately post-ban, increasing over subsequent waves (103.8 ”g/m3 and 158.2 ”g/m3 respectively). Controlling for potential influential factors such as ventilation, time of day, day of week, city and venue type, all post-ban measurements were still lower than during the pre-ban period (Wave 2 beta: â118.7, Wave 3 beta: â87.6, and Wave 4 beta: â69.9). Outdoor or indoor signage banning smoking was not found to affect SHS concentrations (beta: â10.9, p = 0.667 and beta: â18.1, p = 0.464 respectively). However, ashtray or ashtray equivalents were strong determinants of the existence of indoor SHS (beta: +67 ”g/m3, p = 0.017). Conclusions: While the public may be supportive of smoke-free legislation, adherence may decline rapidly if enforcement is limited or nonexistent. Moreover, enforcement agencies should also focus on the comprehensive removal of ashtray equivalents that could act as cues for smoking within a venue
A systematic review on outbreaks of COVID-19 among children within households in the European region

Unaddressed privacy risks in accredited health and wellness apps: a cross-sectional systematic assessment
Understanding how perceptions of tobacco constituents and the FDA relate to effective and credible tobacco risk messaging: A national phone survey of U.S. adults, 2014â2015
As reported in the original paper [1], the Center for Regulatory
Research on Tobacco Communication conducted a
telephone survey in 2014â2015 with a national sample of
adults ages 18 and older living in the United States
(N = 5014). Poverty level was determined using the household
size and income reported by the respondents and
applying the federal poverty numbers available from the
U.S. Department of Health and Human Services in 2014.
A coding error was made during the data recoding process
such that 2.7% of respondents (n = 129) were incorrectly
classified as living above the poverty line. Below are
updated Tables 1, 2 and 4 presenting both the original and
corrected estimates. No substantive conclusions reported
in the paper were affected by this correction
Adherence to treatment to help quit smoking: effects of task performance and coping with withdrawal symptoms
Background:
Currently the combined cognitive-behavioral and pharmacological treatment is the best option to quit smoking, although success rates remain moderate. This study aimed to identify predictors of continuous abstinence in an assisted smoking cessation program using combined treatment. In particular, we analyzed the effects of socio-demographic, smoking-, and treatment-related variables. In addition, we analyzed the effect of several risk factors on abstinence, and estimated a model of risk for smoking relapse.Methods:
Participants were 125 workers at the University of Granada (50 males), with an average age of 46.91 years (SDâ=â8.15). They were recruited between 2009 and 2013 at an occupational health clinic providing smoking cessation treatment. Baseline measures included socio-demographic data, preferred brand of cigarettes, number of years smoking, use of alcohol and/or tranquilizers, past attempts to quit, Fargerström Test for Nicotine Dependence, Smoking Processes of Change Scale, and Coping with Withdrawal Symptoms Interview. Participants were invited to a face-to-face assessment of smoking abstinence using self-report and cooximetry hemoglobin measures at 3, 6, and 12 months follow-up. The main outcome was smoking status coded as ârelapseâ versus âabstinenceâ at each follow-up. Kaplan-Meier survival analysis was performed to estimate the probability of continued abstinence during 12 months and log-rank tests were used to analyze differences in continued abstinence as a function of socio-demographic, smoking-, and treatment-related variables. Cox regression was used to analyze the simultaneous effect of several risk factors on abstinence.Results:
Using alcohol and/or tranquilizers was related to shorter abstinence. Physical exercise, the number of treatment sessions, performance of treatment tasks, and coping with withdrawal symptoms were related to prolonged abstinence. In particular, failure to perform the treatment tasks tripled the risk of relapse, while lack of coping doubled it.Conclusions:
Our results show that physical exercise, performance of treatment-related tasks, and effective coping with withdrawal symptoms can prolong abstinence from smoking. Programs designed to help quit smoking can benefit from the inclusion of these factors.This research was supported by the Occupational Medicine Area (Prevention Service) of the University of Granada
