The present study included 9,053 adults from 14 countries that participated in the European Community Respiratory Health Survey II. The mean follow-up period was 8.8 yrs. Change in the prevalence of active and passive smoking was expressed as absolute net change (95% confidence interval) standardised to a 10-yr period. Determinants of change were analysed and the results expressed as adjusted hazard risk ratio (HRR) or odds ratio (OR). The prevalence of active smoking declined by 5.9% (5.1–6.8) and exposure to passive smoking in nonsmokers declined by 18.4% (16.8–20.0). Subjects with a lower educational level (HRR: 0.73 (0.54–0.98) and subjects living with a smoker (HRR: 0.45 (0.34–0.59)) or with workplace smoking (HRR: 0.69 (0.50–0.95)) were less likely to quit. Low socio-economic groups were more likely to become exposed (OR: 2.21 (1.61–3.03)) and less likely to cease being exposed to passive smoking (OR: 0.48 (0.37–0.61)). In conclusion, the quitting rate was lower and the risk of exposure to passive smoking higher among subjects with lower socio-economic status. Exposure to other peoples smoking decreased quitting rates and increased the risk of starting to smoke. ER -
