Stop smoking strategies are associated with slower lung function decline. We used the BOLD data to describe the use of stop smoking prevention across 20 sites.Methods: Reported use of stop smoking advice and medicines was assessed among population based samples of smokers aged 40+ with and without Chronic Airways Obstruction (CAO) (FEV1/FVC<Lower Limits of Normal).Results: Smoking prevalence ranged from 8.5% in Mumbai, India to 69.5% in Cape Town, S. Africa. The rate of stop smoking prevention use ranged from 0% in Mumbai and Pune, India to 24.7% in Lexington, USA. It was higher in current smokers than in ex-smokers (13.3% vs 6.3%, p<0.0001), in those with CAO than in those without CAO (15.3% vs 7.7%, p<0.0001) and in high income countries (HIC) than in low and middle income countries (LMIC) (11.6% vs 1.9%, p<0.0001).The use of stop smoking prevention was more likely in women, younger, more educated people (OR=1.36; 95%CI 1.18-1.56), those with low lung function (OR=3.93; 95%CI 1.58–9.75), comorbidities (OR=1.41; 95%CI 1.04-1.91), symptoms (OR= 1.71; 95%CI 1.21-2.42) and increased with each 10pack-years smoked (OR=3.47; 95%CI2.61- 4.61). Overall positive effects did vary across sites except for the effect of gender and education but these differences do not explain the difference in use between LMIC and HICs.Ecological analyses suggest little positive effect of high usage of stop smoking prevention.Conclusion: Use of stop smoking prevention is associated with chronic respiratory disease and pack-years smoked, is higher in current smokers than in ex-smokers and in HICs than in LMICs. Understanding factors influencing use and optimising use in current-smokers and LMICs are important. ER -
