    Second-hand tobacco smoke (SHS) is a major indoor pollutant that causes serious health problems for all exposed, especially children. Children are often exposed to SHS at home, due to parental or other households' or guests' smoking. This study describes Portuguese children's exposure to SHS at home (total and by Portuguese main regions). In 2010/2011, a questionnaire was applied to a sample of Portuguese children in the 4th grade (N=3187, mean age 9.05±0.7 years, 51.1% male). Descriptive analysis, chi-square tests and crude odds ratios were performed. Of the participants, 62.9% of those with smoking parents and 19.2% of those with non-smoking parents were exposed to SHS at their home. Parental smoking varied significantly among regions and was significantly associated with children's exposure to SHS at home. Children's exposure to SHS at home was high, especially if their parents smoke. Children living in Lisbon Region presented the highest SHS exposure rate. The association of SHS exposure with geographic regions suggests the influence of social and contextual factors on smoking behaviour and on tobacco control effectiveness. Our findings highlight the need to effectively prevent children's SHS exposure at their home and to develop tailored tobacco control measures by region.

  • Prevalence of Portuguese Children Exposed to Secondhand Smoke at Home and in the Car
    Publication . Precioso, J; Rocha, V; Sousa, I; Araújo, AC; Machado, JC; Antunes, H
    Introduction: Children’s exposure to secondhand smoke is a cause of serious health problems and infant morbidity. This is the first nationally representative study conducted in Portugal to describe the prevalence of children exposed to secondhand smoke at home and in the car. Material and Methods: This is a descriptive cross-sectional study with a representative sample of 2396 Portuguese children aged 0 to 9 years old, stratified by age and administrative region NUTS II. Questionnaires were administered between January and September 2016. Results: Results showed that 6.1% of mothers and 11.2% of fathers reported smoking at home. It was found that 4.5% of mothers and 8.3% of fathers reported smoking in the car. Results also showed that 5.4% of children were double exposed to secondhand smoke at home and in the car. Children whose parents were smokers and had a lower level of education were more exposed to secondhand smoke at home. Discussion: Children’s exposure to secondhand smoke has been decreasing in Portugal. Parental smoking and a low educational level were risk factors for children’s exposure to secondhand smoke at home. Conclusion: The main source of children’s exposure to secondhand smoke is parental smoking. As such, it is crucial to implement effective measures to control parental smoking. It is necessary to promote smoking cessation among parents and to ban smoking inside the car.

  • Prevalence of secondhand smoke exposure in asthmatic children at home and in the car: A cross-sectional study
    Publication . Antunes, H; Precioso, J; Araújo, AC; Machado, JC; Samorinha, C; Rocha, V; Gaspar, A; Becoña, E; Belo-Ravara, S; Vitória, P; Rosas, M; Fernandez, E
    Objective: To compare secondhand smoke exposure (SHSe) prevalence at home and inside the car between asthmatic and non-asthmatic Portuguese children. Materials and methods: This is a cross-sectional study that assessed children’s SHSe in a representative sample of nine Portuguese cities. A validated self-reported questionnaire was administered to a random sample of 4th grade students during the school year of 2010/2011. The asthma prevalence was defined by the answers to three questions regarding asthma symptoms, medication and inhaler use. We performed chi-square tests and analysed frequencies, contingency tables, confidence intervals, and odd-ratios. Results: The self-reported questionnaire was administered to 3187 students. Asthma prevalence was 14.8% (472 students). Results showed that 32.3% of non-asthmatic children and 32.4% of asthmatic children were exposed to secondhand smoke as at least one of their household members smoked at home. The prevalence of parental smoking, smoking among fathers and smoking among mothers at home was also similar in both groups (asthmatic and non-asthmatic children). SHSe inside the car was 18.6% among non-asthmatic children and 17.9% among asthmatic children.Conclusions: Asthmatic and non-asthmatic children were equally exposed to secondhand smoke, because no significant differences were found between the two groups concerning the prevalence of SHSe at home and inside the car. These findings highlight the need to include SHSe brief advice in paediatric asthma management.
