Subjects were submitted to assessment of lung function, smoking habits, functional exercise capacity, health related quality of life (HRQL), anxiety and depression, as well as PADL using a step counter. The groups were divided in active or inactive subgroups according to the number of steps/day (< or > 10000 steps/day).Results: Average steps/day was 8645±4204 in GS and 9480±3550 in GNS (p>0.05). In GS, there was significant difference between active and inactive subgroups in steps/day, distance walked and%pred of the 6-minute walk test (6MWT) (13209±2939 steps/day; 569±70 m; 84±8%pred versus 5985±2529 steps/day; 514±53 m; 78±8%pred, respectively; p=0.02 for all). Active smokers showed no difference in comparison to active nonsmokers concerning steps/day, lung function and HRQL (p>0.05 for all), despite a significant difference in the 6MWT (p<0.05). PADL level in GS correlated modestly with the 6MWT both in meters and%pred (r=0.34 and 0.31; p<0.002 for both). A linear regression model showed that 6MWT explained 10% of GS steps/day variation (adjusted R2=0.104).Conclusions: In general, smokers walk as much as nonsmokers in daily life, especially when comparing the physically active subjects from both groups. Active smokers showed PADL, lung function and HRQL similar to active nonsmokers, although with reduced exercise capacity. ER -
