Cross-sectional evaluation of the association between greenness and cognitive performance in Mexican pre-pubertal boys.

BACKGROUND: Evidence shows that greenspace exposure benefits children's health and cognitive development. However, evidence assessing this association in young children in low- and middle-income economies is scarce. OBJECTIVE: To assess the association between exposure to greenness and cognitive performance in pre-pubertal boys living in Mexico City. METHODS: Cross-sectional study using data from 144 boys aged 6-11 years living in Mexico City in 2017 and enrolled in the "MetCog" study. Cognitive performance was evaluated through selected Wechsler Scale for Intelligence in Children Fourth Edition (WISC-IV) and Neuropsychological Assessment of Children (Evaluación Neuropsicológica Infantil, ENI) tests. Exposure to greenness was assessed through Normalised Difference Vegetation Index (NDVI) at 300, 500, 1500, 2000, and 3000 m buffer zones from children's residences. Multiple linear regression analysis was undertaken to assess associations between cognitive performance and greenness (aß) with 95% confidence intervals (CI) and adjusted for potential confounding variables. Significance was set at q < 0.05 after False Discovery Rate (FDR) correction. RESULTS: A positive association was found between the NDVI Interquartile Range (IQR) at 2000 m and the WISC-IV block design test score (aß 2000 = 1.18, 95% CI = 0.31, 2.06; q < 0.05), which assesses perceptual reasoning. Positive associations were found with NDVI IQR at 1500 m and WISC-IV block design (aß1500 = 1.00, 95% CI = 0.14, 1.86) and matrix reasoning (aß1500 = 0.83, 95% CI = 0.06, 1.61) scores, but neither survived FDR correction. No significant associations were found between NDVI IQR at any buffer size with other WISC-IV and ENI task scores. CONCLUSIONS: Greater exposure to greenness was associated with higher perceptual reasoning skills in 144 pre-pubertal boys living in Mexico City. Thus, urban planning should consider increasing vegetation in megacities, especially in neighbourhoods with high percentages of young children.

Association between Leisure Screen Time and Emotional and Behavioral Problems in Spanish Children.

OBJECTIVE: To assess the relation between leisure screen time and emotional and behavioral problems in Spanish children aged 4-14 years. STUDY DESIGN: This cross-sectional study used a representative sample of children aged 4-14 years included in the 2017 Spanish National Health Survey (n = 4073). Emotional and behavioral problems of children were assessed through the parent-report Strengths and Difficulties Questionnaire. Daily leisure screen time in minutes was categorized as 0-59, 60-119, 120-179, and ≥180. We calculated adjusted prevalence ratios (aPR) and their 95% CIs of being at risk of developing emotional and behavioral problems. Associations were adjusted for potential confounding variables. RESULTS: Children spending 180 minutes or more of daily leisure screen time compared with children spending less than 1 hour were more likely to be at risk of developing emotional and behavioral problems: aPR≥180: 2.19 (95% CI 1.53-3.14), emotional symptomology: aPR≥180: 2.09 (95% CI 1.37-3.18), conduct problems aPR≥180: 1.85 (95% CI 1.34-2.54), peer problems aPR≥180: 1.78 (95% CI 1.15-2.75), and to behave less prosocially: aPR≥180: 2.20 (95% CI 1.43-3.37). CONCLUSIONS: We have found significant associations between daily leisure screen time and emotional and behavioral problems in Spanish children between 6 and 14 years of age. However, these findings should be confirmed in cohort studies, so institutions might consider including screen time as a new risk factor for children.

Association of screen time and sleep duration among Spanish 1-14 years old children.

BACKGROUND: Due to the change in screen time usage in the last decade, there is needed to add more evidence about the relationship of screen time and sleep duration. OBJECTIVE: To assess the association between screen time and sleep duration among Spanish children between 1 and 14 years old. METHODS: We used data from the 2017 Spanish National Health survey, conducted on a representative sample of the Spanish population. We categorised daily leisure screen time as 0-59, 60-119, 120-179, and ≥180 minutes. We classified sleep duration, depending on the age, as proper sleep duration and short sleep duration. We calculated unadjusted, and adjusted prevalence ratio (PR) and 95% confidence interval (CI) of short sleep duration according to daily leisure screen time after adjusting for potential confounders. PR's were derived from fitting generalised linear models with Poisson distribution and robust variance. RESULTS: Of the 5517 Spanish children aged 1-14 years, 44.3% spent 120 minutes or more of daily leisure screen time and 23.6% had short sleep duration. 24.5% and 28.2% of children spending between 120 and 179 minutes and exceeding 180 minutes of daily leisure screen time suffered short sleep duration, respectively. In the adjusted model, higher patterns of daily leisure screen time were associated with short sleep duration: adjusted PR120-179  = 1.34 (95% CI 1.18, 1.54) and adjusted PR≥180  = 1.48 (95% CI 1.27, 1.73). CONCLUSIONS: Around one out of four Spanish children between 1 and 14 years old, exceeding 120 minutes of daily leisure screen time, had short sleep duration. More scientific research is needed for institutions to work on providing novel healthcare programmes that consider these new determinants of child health.

How do infants and toddlers sleep in Spain? A cross-sectional study.

There is limited information on sleep patterns among infants and toddlers in Spain. The aim of this study was to assess sleep patterns in children three to 36 months of age in Spain. A cross-sectional study was conducted between February 2017 and February 2018. Sociodemographic data and sleep variables were collected using an expanded version of the validated Spanish version of the brief infant sleep questionnaire. A total of 1,404 parental reports on children (725 males; 679 females) with a mean age of 18.8 ± 9.5 months were collected. Parents who perceived their child's sleep as problematic (39% of our sample) reported fewer sleep hours (median 9 versus 10 h), more night awakenings (median 2 versus 1), and longer periods of nocturnal awakenings (median 0.5 versus 0.08 min) (p < 0.001). Parental presence at the time of sleep onset and later and irregular bedtime routines were significantly associated with a reduction in total sleep time, longer sleep latency, and disruptive night awakenings (p < 0.001). These findings highlight the need for further studies to assess how to improve sleep patterns as a relevant modifiable lifestyle factor.Conclusion: A substantial percentage of the population perceived that their children slept poorly, which was evident in a variety of sleep patterns, including sleep duration and sleep quality. What is known: • Previous research has established that sleep difficulties among pediatric population affect up to 30% of all children and up to 20-30% of infants and toddlers. • A positive relationship between less parental bedtime involvement and sleep consolidation in infants and toddlers has been established. What is new: • More than a third of Spanish parents perceived their infants and toddlers sleep as problematic and their children reportedly have shorter night sleep hours, more night awakenings, and longer periods of nocturnal awakenings. • Later and irregular parental bedtime routines were associated with worst infants and toddlers sleep.

Prevalence and determinants of metabolic syndrome in Spanish salaried workers: evidence from 15 614 men and women.

OBJECTIVE: To describe the prevalence of Spanish workers with Metabolic Syndrome (MetS) and those at risk of developing MetS in 2015. METHODS: Cross-sectional study of workers (n = 15 614). We used a modified definition of the NCEP:ATPIII criteria for MetS (we used body mass index (BMI) above 28.8 kg/m2 instead of the waist circumference criterion). We calculated the prevalence of MetS (having at least three components) and of being at risk of MetS (having one or two components). We calculated adjusted odds ratios (aOR) of MetS according to socio-economic and workplace characteristics. RESULTS: The proportions of workers with and at risk of MetS were 7.1 and 31.9%, respectively. The most prevalent criterion was having a BMI > 28.8 kg/m2 (24.1%) in men and cHDL < 40 mg/dl in women (12.9%). There were significant associations between MetS and men (aOR compared to women = 3.73, CI 95%: 3.19; 4.36); age (higher among oldest, aOR = 5.75, CI 95%: 4.37;7.56); and social class (higher among lower social class, aOR = 2.03, CI 95%: 1.65;2.48). CONCLUSION: Reducing any of the five MetS components, while taking into account the differences found by socio-economic and workplace characteristics, should be one priority for reducing MetS prevalence.

Relation between tobacco control policies and population at high risk of lung cancer in the European Union.

INTRODUCTION: Lung cancer accounts for nearly 2 million deaths per year worldwide, the majority of cases due to smoking as the main risk factor associated. The aim of this study was to assess the relation between the level of implementation of tobacco control policies and the population at high risk of lung cancer in the European Union (EU). METHODS: The Special Eurobarometer 458 "Attitudes of Europeans towards tobacco and electronic cigarettes", conducted in 2017, and the Tobacco Control Scale (TCS) 2010, 2013, and 2016 were the sources of our data. High risk of lung cancer was defined by the inclusion criteria in the National Lung Screening Trial (NLST) and the Dutch-Belgian Lung Cancer Screening Trial (NELSON), the largest lung cancer screening trials carried out in the US and the EU. We calculated Spearman's rank correlation coefficients (rsp) and fitted multilevel generalized linear mixed models using the quasi-Poisson family to assess the correlation at the national level and analyze the association at the individual level, respectively, between the scores in the TCS (higher scores means better implementation of tobacco control policies) and the proportion of individuals at high risk of lung cancer in member states of the EU. RESULTS: The scores in the TCS 2010 were statistically negatively correlated with the current proportion of ever and former smokers at high risk according to NELSON criteria (-0.41; 95%CI -0.68, -0.04 and -0.49; 95%CI -0.73, -0.13, respectively). We observed statistically significant inverse associations between the scores in the TCS 2010 for the highest quartiles and the proportion of individuals at high risk of lung cancer according to both criteria. Non-statistically significant negative correlations and inverse associations were observed with other TCS. CONCLUSION: There is a lag between the implementation of tobacco control policies and the reduction of the rates of high risk of lung cancer. Member states should reinforce comprehensive tobacco control policies to reduce the population at high risk of lung cancer in the EU.

Comparison of TSNAs concentration in saliva according to type of tobacco smoked.

OBJECTIVE: To compare tobacco-specific nitrosamines (TSNAs) measured in saliva according to different types of tobacco smoked in a sample of smokers of the city of Barcelona (Spain). METHODS: We used data from a cross-sectional study of a sample of the adult smoking population of Barcelona, Spain in 2013-2014 (n = 165). We classified smokers in five groups according to the type of tobacco smoked: a) manufactured cigarettes only, b) roll-your-own (RYO) cigarettes only, c) dual smokers (both manufactured and RYO cigarettes), d) manufactured plus other types of tobacco products different from RYO and e) other types of tobacco products different from manufactured and RYO cigarettes. We calculated the geometric mean (GM) and geometric standard deviation (GSD) of TSNAs concentration in saliva (pg/mL), including N'-nitroaonornicotine (NNN), 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK) and 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol (NNAL) according to the five tobacco groups. We also described all TSNAs concentration in each tobacco group stratified by the number of cigarettes smoked per day. RESULTS: Smokers from the RYO cigarette group had higher TSNAs concentration than smokers from the manufactured cigarette group: 13 pg/mL vs 4.9 pg/mL of NNN, 1.9 pg/mL vs 1.7 pg/mL in NNK and 1.1 pg/mL vs 0.9 pg/mL of NNAL. There were significant differences in NNN concentrations between smokers of RYO vs manufactured cigarettes. The higher the number of cigarettes smoked, the higher the TSNAs concentrations. After adjusted by number of cigarettes smoked, there were not statistically significant differences in TSNAs between RYO and manufactured cigarettes. CONCLUSIONS: Our data shows that RYO cigarette is at least as hazardous as manufactured cigarettes. Regulating RYO tobacco prices could be an effective strategy to control tobacco use.

Specific biomarker comparison in current smokers, e-cigarette users, and non-smokers.

INTRODUCTION: This study aims to address the existing gap in the literature, while adding evidence, by comparing tobacco-specific biomarkers (cotinine and nitrosamines: NNK, NNAL, NNN), and other biomarkers of e-cigarette use (humectants: glycerol, 1,2-PD, 1,3-PD) according to five study groups. METHODS: A pooling analysis including two different studies was conducted. In both analyses, we took saliva samples from smokers (n = 409) and non-smokers (n = 154), dual tobacco and e-cig users (n = 92), exclusive e-cig user with nicotine (n = 158), and exclusive e-cig users without nicotine (n = 38). We analyzed and compared the geometric means (GM) and geometric standard deviations (GSD) of the concentration of tobacco-specific biomarkers, and e-cigarette biomarkers among groups. We used log-linear models adjusted for sex and age to model the change percentage and their 95% confidence intervals. RESULTS: Cotinine was significantly higher in nicotine consumers and in e-cigarette users without nicotine when compared to non-smokers. TSNAs were generally significantly lower in non-smokers and higher in nicotine consumers. NNN and NNAL were lower in e-cigarette users with nicotine comparted to smokers, and NNN was higher in e-cigarette users without nicotine when compared to non-smokers. No differences were found in humectant biomarkers between e-cigarette groups. CONCLUSIONS: Although there was a reduction in TSNAs in e-cigarette exclusive users compared to smokers, and a reduction of cotinine concentrations in e-cigarette exclusive users without nicotine compared to smokers, there are still high levels of these biomarkers when compared to non-smokers, which may be a clue towards the harmful effect of e-cigarettes.

Relationship between double COVID-19 vaccine uptake and trust in effectiveness and safety of vaccination in general in 23 Member states of the European Union: an ecological study.

INTRODUCTION: The aim of this study was to assess the relationship between double COVID-19 vaccine uptake and trust in effectiveness and safety of vaccination in general in 23 European Union (EU) countries. METHODS: Ecological study. Data was retrieved from the Flash Eurobarometer 494 and Our World in Data. We estimated Pearson's correlation coefficients and fitted multiple linear regression models. RESULTS: There is a negative linear correlation between the percentage of people doubly vaccinated and the percentage of low trust in vaccine effectiveness (r = -0.48, p-value = 0.021), and the percentage of low trust in vaccine safety (r = -0.43, p-value = 0.041). There is a negative adjusted relation between the percentage of low trust in vaccine safety and the percentage of people doubly vaccinated (aß% low trust in vaccinesafety:-0.25; 95% CI: -0.49,-0.01, p-value = 0.045). CONCLUSION: An increase in health literacy of people living in certain countries in the EU may be needed to boost COVID-19 vaccine uptake.

Compliance Surveillance of the Tobacco Control Legislation in a Spanish Region and Characterization of Passive Exposure to Tobacco Smoke and E-Cig in Children in Outdoor Spaces.

(1) Background: Exposure to environmental tobacco smoke has decreased in recent years in Spain, due to the implementation of tobacco control policies. However, there is no regulation that protects against second-hand smoke (SHS) in outdoor environments. Our goal is to describe the smoking prohibition signage in public spaces and to characterize tobacco consumption in outdoor environments describing the SHS exposure in children. (2) Methods: A cross-sectional study using direct observation was carried out with a convenience sample (n = 179) that included hospitality venues with terraces, schools and healthcare facilities in the municipality of Sant Cugat del Vallès (Barcelona, Spain). The observations were made without notifying the owners by one single field researcher between April and June 2018. The variables were evaluated by signage and signs of tobacco consumption (ashtrays, cigarette butts and presence of smokers). (3) Results: Smoke-free zone signage outside public spaces was present in 30.7% of all venues, with only 50.9% correctness. When analysing terraces of hospitality venues, in 35.8% of them there were children present with 66.7% of tobacco consumption. (4) Conclusions: Our results show a low prevalence of antismoking signage, without an impact on tobacco consumption regardless of the presence of children.

Association between recreational screen time and excess weight and obesity assessed with three sets of criteria in Spanish residents aged 2-14 years.

INTRODUCTION AND OBJECTIVE: Studies that assess the association between excess weight and screen time in childhood and adolescence are methodologically heterogeneous, and few studies have analysed the exposure to smartphones and tablets. Our study aimed to assess the association between daily recreational screen time and excess weight (overweight+obesity) and obesity in children aged 2-14 years residing in Spain using different sets of standards. METHODS: We conducted a cross-sectional study using data from the 2017 Spanish National Health Survey (N=4528). We assessed the prevalence of overweight and obesity applying the criteria of the World Health Organization (WHO), International Obesity Task Force (IOTF), and Orbegozo 2011 study. We categorised daily recreational screen time in minutes as 0-59, 60-119, 120-179, and ≥180. We calculated crude and adjusted prevalence ratios (aPR) of excess weight and obesity based on the daily minutes of recreational screen time with the corresponding 95% confidence intervals (95%CI). Moreover, we calculated crude and adjusted change (aΔ) in the expected number of fulfilled excess weight/obesity criteria based on the minutes of daily recreational screen time with the corresponding 95% CI. We adjusted the association analyses for potential confounders. RESULTS: We found that spending 180min or more a day of recreational screen time was associated with an increase in the adjusted prevalence of excess weight (e.g. Orbegozo 2011 aPR≥180, 1.20; 95% CI, 1.02-1.42) and of obesity (e.g. IOTF aPR≥180, 1.41; 95% CI, 1.06-1.86) as well as an increase in the adjusted number of fulfilled criteria for excess weight (aΔ≥180, 1.18; 95% CI, 1.06-1.31). CONCLUSIONS: Longer periods of recreational screen time were associated with excess weight and obesity in children aged 2-14 years. Cohort studies are required to confirm these findings, as this may be a determinant of health in children.

Association between biomarkers of tobacco consumption and lung cancer risk among daily smokers.

BACKGROUND: Biomarkers of tobacco consumption may play a role in the lung cancer risk assessment. However, the role of salivary biomarkers has not been well studied. The aim of this study is to assess the use of salivary biomarkers of tobacco consumption as lung cancer screening criterion. RESEARCH DESIGN AND METHODS: Data came from the Determinants of cotinine phase 3 project (Barcelona, 2013-2014). We compared the concentrations of TSNAs, including NNAL, NNN and NNK, and cotinine, in saliva samples of 142 daily smokers from the general population according to their risk of lung cancer. High risk of lung cancer was defined as per the inclusion criteria in the US National Lung Screening Trial (NLST) and in the Dutch-Belgian lung cancer screening trial (NELSON). RESULTS: Among daily smokers accomplishing the age criterion for lung cancer screening, salivary concentrations of cotinine, NNAL and NNK adjusted for sex were significantly higher (p-value < 0.05) in daily smokers at high risk of lung cancer compared to smokers not at high risk according to both NELSON and NLST criteria. CONCLUSIONS: Saliva concentrations of cotinine, NNAL and NNK may be used as additional criteria for lung cancer screening. Further research on this topic is guaranteed.

Knowledge and Opinions of Healthcare Professionals about Thirdhand Smoke: A Multi-National, Cross-Sectional Study.

There is scarce evidence on the knowledge and opinions about third-hand smoke (THS) of health care professionals. The main aim of this study was to explore the knowledge and opinions of health care professionals about THS and, secondarily, to explore the factors that are associated with this knowledge. Cross-sectional study using a snowball sample of multi-national health care professionals (n = 233). Data were obtained from an exploratory, online questionnaire. The health care professionals' knowledge and opinions on THS were described with absolute frequency and percentage. Chi-square and Fisher-Freeman-Halton exact tests, and simple logistic regression models, were used to explore the bivariate association between the knowledge of the concept THS and sex, continent of birth, educational level, occupation, years of experience, and attitude towards smoking. Finally, a multivariable logistic regression model incorporating all the above variables was fitted. A total of 65.2% of the participants were unaware of the term THS before the study began. In the bivariate analysis, an association was found between prior knowledge of the term THS and continent of birth (p-value = 0.030) and occupation (p-value = 0.014). In the multivariable logistic regression model, a significant association was observed between prior knowledge of the concept THS and sex (p-value = 0.005), continent of birth (p-value = 0.012), and occupation (p-value = 0.001). Almost two out of three health care professionals who participated in our study did not know what THS was. Educational activities on this topic should be implemented.

Differences in sleep duration in a territory with the same time zone according to the geographic longitude: the Spanish case.

OBJECTIVE/BACKGROUND: In some territories, such as Spain, daytime starts with around 1 h of difference between the easternmost and westernmost areas, but the time zone is the same in these areas. This difference might have an effect on children's sleep. The aim of this study is to assess if there are differences in the prevalence of short sleep duration between children under 15 years from easternmost (Catalonia) and westernmost (Galicia) continental territory areas in Spain. METHODS: Cross-sectional study using data from the 2017 Spanish National Health Survey (n = 6106). The final sample includes 1004 children under 15 years living in Catalonia and Galicia. We categorized sleep duration according to the National Sleep Foundation recommendations with respect to age in (1) not short sleep duration and (2) short sleep duration. We calculated overall percentages of short sleep duration, and unadjusted and adjusted Prevalence Ratios (PR) with 95% Confidence Intervals (95% CI), according to area and stratified by confounders and covariates. Unadjusted and adjusted PR were obtained through generalized linear models with Poisson family and robust variance. We adjusted the associations for confounders. RESULTS: Children from Galicia were less likely to have short sleep duration than children from Catalonia, aPRGalicia = 0.61 (95% CI: 0.45,0.83). CONCLUSIONS: Children living in the same country, potentially with a similar timetable, could be having shorter sleep durations according to their longitude position. Further studies are needed in order to consider promoting policies to apply timetables based on the sun position instead of on the national time zone.

Association between Leisure Screen Time and Junk Food Intake in a Nationwide Representative Sample of Spanish Children (1-14 Years): A Cross-Sectional Study.

Evidence on the association between new patterns of leisure screen time and junk food consumption in Spanish children at the national level is scarce. The aim of this study is to assess the relation between daily leisure screen time and the frequency of sweet, soft drink, fast food, and snack intake in a representative sample of Spanish children and adolescents aged from 1 to 14 years. We conducted a cross-sectional study using a representative sample of the Spanish population under 15 years recruited for the 2017 Spanish National Health Survey (n = 5480). We dichotomized sweet, soft drink, fast food, and snack intake (high/low) and categorized daily leisure screen time (0-59, 60-119, 120-179, and ≥180 min). We calculated crude prevalence ratios and adjusted prevalence ratios, and their 95% confidence intervals (95% CI), of high frequency of sweet, soft drink, fast food, and snack intake. Children spending at least one hour of daily leisure screen time had higher prevalence of high frequency of sweet and snack intake than children being exposed less than one hour. For soft drinks and fast food, prevalence of high frequency intake was significantly higher from two and three hours of exposure, respectively. Longer periods of screen exposure in Spanish children during their leisure time may be associated with poorer dietary behaviors. The negative effects of excessive screen time in pediatrics population should be further studied.

Smartphone and Tablet Usage during COVID-19 Pandemic Confinement in Children under 48 Months in Barcelona (Spain).

BACKGROUND: Total lockdown due to COVID-19 pandemic might have potentially increased screen time in children. This study aims to describe the smartphone and tablets usage in children under 48 months living in Barcelona during the COVID-19 confinement. METHODS: Cross-sectional study using a non-probabilistic sample of parents with children under 48 months living in Barcelona (Spain) during COVID-19 confinement (n = 313). We calculated percentages of exposure to smartphones and tablets. Moreover, for those children were exposed, we calculated unadjusted and adjusted Geometric Mean Ratios (GMR) of daily smartphones and tablets usage and their 95% confidence intervals (95% CI) trough Generalized Linear Models with Gamma family and link log. Associations were adjusted for potential confounders. RESULTS: During COVID-19 confinement, 67.5% of children under 48 months were daily exposed to smartphones and tablets. Further, those children who were exposed during meals, as well as before going to bed, spend longer durations using them, aGMR = 2.38 (95% CI 1.73, 3.34) and aGMR = 1.95 (95% CI 1.34, 2.91) respectively. CONCLUSION: Two out of three children under 48 months living in Barcelona were daily exposed to smartphones and tablets during total lockdown due to COVID-19. Taking this findings into account cohort studies are needed to assess any change in the screen time patterns due to total confinement in order to allow the Government help families, particularly those more vulnerable, in a possible pandemic resurgence.

Estimation of the Risk of Lung Cancer in Women Participating in a Population-Based Breast Cancer Screening Program. / Estimación del riesgo de cáncer de pulmón en mujeres que participan en un programa de cribado poblacional de cáncer de mama.

INTRODUCTION: Lung cancer mortality is increasing in women. In Spain, estimates suggest that lung cancer mortality may soon surpass breast cancer mortality, the main cause of cancer mortality among women. The aim of this study was to estimate the proportion of women at high risk of developing lung cancer in a group of participants in a population-based breast cancer screening program. METHODS: Cross-sectional study in a sample of women who participated in a population-based breast cancer screening program in 2016 in Hospitalet de Llobregat (n=1,601). High risk of lung cancer was defined according to the criteria of the National Lung Screening Trial (NLST) and the Dutch-Belgian randomized lung cancer screening trial (NELSON). RESULTS: Around 20% of smokers according to NLST criteria and 40% of smokers according to NELSON criteria, and around 20% of former smokers according to both criteria, are at high risk of developing lung cancer. A positive and statistically significant trend is observed between the proportion of women at high risk and nicotine dependence measured with the brief Fagerström test. CONCLUSIONS: A high proportion of participants in this breast cancer screening program have a high risk of developing lung cancer and would be eligible to participate in a lung cancer screening program. Population-based breast cancer screening programs may be useful to implement lung cancer primary prevention activities.

[Support to smoking regulation in private vehicles and public outdoor spaces]. / Apoyo a la regulación de fumar en el interior de vehículos privados y espacios públicos al aire libre.

OBJECTIVE: To know the support of tobacco regulation is a very important issue to advance in the tobacco control policies and reduce the passive exposure to tobacco. The aim of this study was to describe the attitudes towards forbidding smoking in private vehicles and public outdoor spaces. METHODS: This is a cross-sectional study of a representative sample (n=736) of the adult population (24+ years old) from Barcelona, Spain in 2013-2014. We calculated the percentages of individuals who had a favourable attitude towards smoking regulation in private vehicles and public outdoor spaces, their adjusted Odds ratios (aOR) and their 95% confidence intervals (95%CI) according to sex, age, educational level and smoking status through logistic regression. We used weighted data for all analyses in order to keep the representativeness of the population of Barcelona in 2013-2014. RESULTS: 61.7% of participants supported forbidding smoking in private vehicles and 89.5% supported forbidding it only in the presence of minors. The support to smoking regulation in public outdoor spaces varied from 42.5% to 84.7% in different settings. Smokers showed a less favourable attitude towards an extension of the smoking regulation to other settings: outdoor areas of university centres, outdoor areas of shopping centres and beaches and outdoor pools. CONCLUSIONS: A wide support exists to extend the smoking regulation to private vehicles, especially in the presence of children, and public outdoor spaces. This wide support could favour the extension of smoking regulation to these places to improve the population's health and to contribute to denormalise tobacco use among the population.

OBJETIVO: Conocer el apoyo a la regulación del consumo de tabaco es una pieza clave para avanzar en las políticas de control del tabaquismo y reducir la exposición pasiva al tabaco. El objetivo de este trabajo fue describir las actitudes hacia la prohibición de fumar en los vehículos privados y espacios públicos al aire libre. METODOS: studio transversal de una muestra representativa (n=736) de la población adulta (mayor de 24 años) de la ciudad de Barcelona, España, realizado en 2013-2014. Se calcularon el porcentaje de individuos que tenían una actitud favorable a la regulación del consumo de tabaco en el interior de vehículos privados y espacios públicos al aire libre, las Odds Ratio ajustadas (ORa) y sus intervalos de confianza al 95% (IC95%) según sexo, edad, nivel de estudios y estatus de consumo de tabaco mediante un modelo de regresión logística. Se utilizaron pesos de probabilidad inversa para mantener la representatividad de la población de Barcelona en 2013-2014. RESULTADOS: El 61,7% de los participantes estuvo a favor de la prohibición de fumar dentro de los vehículos privados y el 89,5% de prohibirlo sólo en presencia de menores. El apoyo a la regulación del consumo de tabaco en espacios exteriores varió entre 42,5% hasta 84,7% dependiendo del ambiente. Los fumadores mostraron una actitud menos favorable a la ampliación de la regulación a otros espacios: zonas exteriores de los centros universitarios, zonas exteriores de los centros comerciales y playas y piscinas descubiertas. CONCLUSIONES: Existe un amplio apoyo a la extensión de la regulación del consumo del tabaco en el interior de vehículos privados, especialmente en presencia de menores, y espacios públicos al aire libre. Este amplio apoyo podría favorecer la ampliación de la regulación del consumo de tabaco a estos espacios a fin de mejorar la salud de la población y al mismo tiempo contribuir a la desnormalización del consumo de tabaco entre la población.

[Prevalence of smoke-free homes and passive exposure to tobacco in pediatric population (children from 3 to 36 months)]. / Prevalencia de hogares libres de humo y exposición pasiva al tabaco en población pediátrica (niños de 3 a 36 meses).

OBJECTIVE: Pediatric population is the most vulnerable to secondhand smoke (SHS), exposure being households the main source of exposure in children. The objective of this study is to describe smoke-free households and the prevalence of SHS in the pediatric population (from 3 to 36 months) in Spain. METHODS: Cross-sectional study with 1,368 parents, mothers or guardians with children from 3 to 36 months carried out in Spain from March to November of 2017 through an online questionnaire as part of the EPISON study. Information was collected on the voluntary adoption of tobacco use regulations at home and SHS exposure at home and other environments. We calculated prevalences and Odds Ratio adjusted (ORa) for sex, age, level of education, and smoking status. RESULTS: 87.6% of respondents claimed to have a smoke-free home. 12.4% of respondents had partial regulation or did not have regulation at home, increasing up to 26.0% when the parent was a smoker or to 21.8% when the parent had primary or lower education. 5.4% of parents reported SHS exposure in their children at their homes, rising to 14.5% when it occurs in other environments, increasing with statistically significant differences between smoking parents and parents with lower educational level. CONCLUSIONS: The smoke-free homes are the majority; but SHS exposure to tobacco at home persists in children under 3 years of age, especially in families with a lower educational level. Therefore, awareness-raising campaigns on the effects of passive exposure on minors among families with.

OBJETIVO: La población pediátrica es la más vulnerable a la exposición pasiva al humo ambiental del tabaco (HAT), siendo los hogares la fuente principal de exposición en niños. El objetivo de este estudio fue describir los hogares libres de humo y la prevalencia de exposición pasiva al HAT en la población pediátrica (de 3 a 36 meses) en España. METODOS: Estudio transversal con 1.368 padres, madres o tutores con hijos de 3 a 36 meses realizado en España de marzo a noviembre de 2017 mediante cuestionario online como parte del estudio EPISON. Se recogió información sobre la adopción voluntaria de normas de consumo de tabaco en el hogar y exposición al HAT en casa y otros ambientes. Se calcularon las prevalencias y las Odds Ratio ajustadas (ORa) por sexo, edad, nivel educativo y consumo de tabaco. RESULTADOS: El 87,6% de los encuestados afirmó tener un hogar libre de humo. El 12,4% de los encuestados tenían regulación parcial o no tenían ninguna regulación en el hogar, incrementándose hasta el 26% cuando el progenitor era fumador o al 21,8% cuando tenía estudios primarios o inferiores. El 5,4% de los padres refirió exposición pasiva al tabaco en niños en sus hogares, elevándose hasta el 14,5% cuando la exposición se produjo en otros ambientes, incrementándose de forma estadísticamente significativa la diferencia entre los padres fumadores y con menor nivel educativo. CONCLUSIONES: Los hogares libres de humo son mayoritarios, pero persiste la exposición pasiva al tabaco en el hogar con niños menores de 3 años, especialmente en familias con menor nivel educativo. Por ello, se deberían incentivar campañas de sensibilización sobre los efectos de la exposición pasiva en menores, especialmente en familias con menos recursos.

Estimation of the adult population at high risk of developing lung cancer in the European Union.

Background Lung cancer mortality accounts for over 266,000 deaths in the European Union (EU) every year, most of them attributed to smoking. The aim of this study was to estimate the prevalence of the adult population at high risk of developing lung cancer in the EU in 2014. Methods This is a cross-sectional study. We used data from the Special Eurobarometer 429 (n = 27,801). The fieldwork was conducted between November-December 2014. High risk of lung cancer was defined using the criteria of the National Lung Screening Trial (NLST) and the Dutch-Belgian Lung Cancer Screening Trial (NELSON). Results One out of ten smokers (11.6% of men and 9.6% of women) according to NLST criteria and one out of four smokers (24.6% of men and 22.4% of women) according to NELSON criteria are currently at high risk of lung cancer in the EU. According to both criteria, the prevalence of former smokers at high risk of lung cancer is under 10%. Conclusion Around 17 million citizens in the EU according to NLST criteria and 34 million according to NELSON criteria (around 4% and 8% of the adult population, respectively) are at high risk of developing lung cancer. Since the implementation of lung cancer screening programs still remains controversial, primary prevention activities should be encouraged.
