| description | Introduction: Cigarette smoking is an addictive behaviour which
continues to rise among young adults. It has been associated with
various health hazards. Effect of smoking on cognitive function
has been contradicting. Thus our aim was to compare cognitive
performances between smokers and non smokers and also to
observe the effect of varying intensity of smoking on cognition.
Materials and Methods: This is a cross-sectional study. Thirty
non smokers, 30 mild smokers, 30 moderate smokers, 30 heavy
smokers within the age group of 25-35 years were involved in the
study. Their cognitive performance were assessed by digit symbol
substitution test (DSST), digit vigilance test (DVT), visual reaction
time (VRT), letter cancellation test (LCT), word recall (WR), and
object recall (OR).
Result: The cognitive data were analysed using unpaired students
t-test and ANOVA in SPSS 19. Smokers showed significant decline
in their cognitive performances when compared to smokers (p ≤
0.05). Mild smokers showed significantly better performance in the
DSST, DVT and VRT tests than the non smokers. This indicates the
attention and alertness were better in mild smokers than the non
smokers. With the increase in the intensity of smoking cognitive
performances were also significantly declined.
Conclusion: Thus the study indicates decreased cognitive
performances in young adult smokers. |
