The intervention targeted schoolchildren in Terrassa (Catalonia, Spain). We assessed SHS exposure in different settings and tobacco consumption by means of a questionnaire before and one year after the intervention.nnRESULTS: We analyzed data from 1734 students with both baseline and follow-up data. The crude analysis showed that SHS exposure among students in the intervention group significantly decreased at school (-14.0%), at home (-19.9%), and on transportation (-21.8%). In the comparison group, SHS exposure significantly decreased only at home (-16.9%). After adjustment for potential confounders, the good accomplishment of the activities showed a possible trend towards a non-significant reduction in exposure at home, transportation, and leisure time.nnCONCLUSION: While this school-based multi-level intervention had no overall effect in SHS exposure, the improvement of the activities focused on preventing SHS would be needed in order to achieve a significant decrease in the proportion of children exposed to SHS.},

abstract = {AIM: To analyse the association between tobacco smoking, exposure to second-hand smoke (SHS) and reports of wheezing and asthma in a sample of schoolchildren.nnMETHODS: A structured questionnaire was administered to 1766 students (7th grade, aged 12-13 years) at 25 schools in Terrassa, Spain (2006). We determined the prevalence of active smoking, exposure to SHS and reports of wheezing and asthma, and their association by means of prevalence odds ratios (OR) and 95% confidence intervals (CI).nnRESULTS: 97.5% of children were nonsmokers, 1.5% were experimental smokers and 1% were regular smokers. 41.1% of children reported exposure to SHS at home, 40.0% at school, 53.9% in their leisure time and 33.2% while using private or public transportation. Wheezing was reported by 9.2% of children, and 9.2% reported asthma. A significant association was found between smoking tobacco and wheezing: OR in experimental smokers = 3.0 (95% CI 1.2-7.7), and OR in active smokers = 4.2 (95% CI 1.4-12.5). Exposure to SHS while using transportation was associated with wheezing (OR = 1.4; 95% CI 1.0-2.0). Tobacco smoking and exposure to SHS were not associated with asthma.nnCONCLUSION: Active and experimental smokers, and those who reported exposure to SHS while using public or private transportation, had higher likelihood of reporting wheezing. No association between active or passive smoking and asthma was observed.},

The rise of multivariate methods, clinical epidemiology, or nutritional epidemiology was reflected in the citation trends.
