Prospective study of exposure to smoking imagery in films and changes in susceptibility to smoking in a cohort of school students in Southern India.

INTRODUCTION: India has unique tobacco-free film and TV rules designed to prevent tobacco uptake. In this study, we examined the potential influence of exposure to smoking imagery in regionally famous films, on susceptibility to smoke in teenagers enrolled in schools in a district in Southern India. METHODS: A longitudinal survey of students, in grades 6 to 8 at baseline in 2017 and grades 7 to 9 one year later in 2018, ascertained prospective incident susceptibility to smoking during the study period in relation to baseline exposure to 27 locally popular films with actual or implied smoking imagery. RESULTS: We analyzed linked data from 33676 participants, and 3973 (11.8%) of the adolescents reported incident susceptibility. There was a significant increase in susceptibility to smoking with increasing exposure at baseline to smoking imagery in films on univariable analysis, highest tertile of exposure relative to no exposure (OR=1.4; 95% CI: 1.0 -2.1, ptrend<0.001), and this trend remained significant (p=0.022) after mutual adjustment for recognized confounders, highest vs no exposure (AOR=1.3; 95% CI: 0.9-1.8). We found no statistically significant association between exposure to tobacco-free film rules and change in susceptibility. CONCLUSIONS: Prospectively, watching films featuring smoking imagery increases adolescents' vulnerability to smoking. Further research revealed no difference in susceptibility change between youth who saw partially compliant films and those who watched non-compliant films. Our findings, thus, underscore the need to incorporate comprehensive approaches to prevent the inclusion of smoking imagery in films.

Uptake and 4-week quit rates from an opt-out co-located smoking cessation service delivered alongside community-based low-dose computed tomography screening within the Yorkshire Lung Screening Trial.

BACKGROUND: Up to 50% of those attending for low-dose computed tomography screening for lung cancer continue to smoke and co-delivery of smoking cessation services alongside screening may maximise clinical benefit. Here we present data from an opt-out co-located smoking cessation service delivered alongside the Yorkshire Lung Screening Trial (YLST). METHODS: Eligible YLST participants were offered an immediate consultation with a smoking cessation practitioner (SCP) at their screening visit with ongoing smoking cessation support over subsequent weeks. RESULTS: Of 2150 eligible participants, 1905 (89%) accepted the offer of an SCP consultation during their initial visit, with 1609 (75%) receiving ongoing smoking cessation support over subsequent weeks. Uptake of ongoing support was not associated with age, ethnicity, deprivation or educational level in multivariable analyses, although men were less likely to engage (adjusted OR (ORadj) 0.71, 95% CI 0.56-0.89). Uptake was higher in those with higher nicotine dependency, motivation to stop smoking and self-efficacy for quitting. Overall, 323 participants self-reported quitting at 4 weeks (15.0% of the eligible population); 266 were validated by exhaled carbon monoxide (12.4%). Multivariable analyses of eligible smokers suggested 4-week quitting was more likely in men (ORadj 1.43, 95% CI 1.11-1.84), those with higher motivation to quit and previous quit attempts, while those with a stronger smoking habit in terms of cigarettes per day were less likely to quit. CONCLUSIONS: There was high uptake for co-located opt-out smoking cessation support across a wide range of participant demographics. Protected funding for integrated smoking cessation services should be considered to maximise programme equity and benefit.

Factores asociados a la sibilancia recurrente en lactantes de La Habana, Cuba / Factors associated to the recurrent wheezing in nurslings of Havana, Cuba

Introducción: en Cuba la prevalencia de sibilancia recurrente a nivel poblacional a edades tempranas es desconocida. Objetivo: identificar la magnitud y factores asociados en el lactante con sibilancia recurrente. Método: diseño epidemiológico transversal. Una muestra de 1956 niños entre las edades de 12 a 15 meses que viven en 4 municipios de La Habana fue seleccionada para su inclusión en el estudio. A los que se les aplicó por los investigadores un cuestionario validad internacionalmente y aplicado en el territorio nacional (ISAAC), con vista a obtener datos del primer año de vida. La sibilancia recurrente fue definida por la presencia de 3 ó más episodios. Resultados: la prevalencia de sibilancia recurrente fue de 20 por ciento. Los factores de riesgo de mayor importancia fueron: historia familiar de asma OR 1,89 (IC 95%:1,09-3,27), sospecha de alergia a picadura de insectos OR 1,75 (IC 95 por ciento: 1,09-2,80), antecedente de distress respiratorio al nacimiento OR 1,74 (IC 95 por ciento: 1,36-2,22) y el uso del paracetamol incluido el kogrip OR 1,40 (IC 95 por ciento: 1,14-1,73). Presencia de diferencias significativas del riesgo de sibilancia recurrente entre los 4 municipios luego del ajuste de factores de confusión. Conclusiones: la sibilancia recurrente fue identificada como un problema de salud en La Habana. Factores de riesgo modificables para la sibilancia recurrente fueron detectados en el grupo estudio, al igual que diferencias del riesgo entre los municipios. Hechos que debe tenerse en cuenta para la elaboración de futuras intervenciones(AU)

Introduction: prevalence of recurrent wheezing among Cuban infants is not known. Objective: Identify the magnitude and factors associated to recurrent wheezing in infants. Method: across-sectional epidemiological study was conducted of a sample of 1 956 children aged 12-15 months from four Havana municipalities randomly selected for inclusion in the research. A questionnaire validated internationally and used in the national territory (ISAAC) was applied to collect data about the first year of life. Recurrent wheezing was defined by the presence of three or more episodes. Results: prevalence of recurrent wheezing was 20 percent. The most important risk factors were a family history of asthma OR 1.89 (CI 95 percent:1.09-3.27), suspected allergy to insect bites OR 1.75 (CI 95 percent: 1.09-2.80), a history of respiratory distress at birth OR 1.74 (CI 95 percent: 1.36-2.22) and the use of paracetamol including Kogrip OR 1.40 (CI 95 percent: 1.14-1.73). Risk for recurrent wheezing showed significant differences between the four municipalities after adjustment for confounding factors. Conclusions: recurrent wheezing was identified as a health problem in Havana. Modifiable risk factors for recurrent wheezing were detected in the study sample. Risk differences were found between the municipalities. These facts should be considered when planning future interventions(AU)
