Key result
Cigarette smoking in young healthy male adults was associated with a significant reduction in psychomotor speed (P<0.001) and sustained attention (P<0.001) compared to non-smokers.
Why the study?
Smoking in older adults is associated with cognitive impairment and decline, but there is a paucity of studies evaluating the effect of cigarette smoke on cognitive functions in younger people.
Does cigarette smoking reduce cognitive performance in young healthy adult males?
Observational (n=60)
Does cigarette smoking reduce cognitive performance in young healthy adult males?
p-value: p=<0.001
Cigarette smoking in young healthy adults is associated with early cognitive decline, specifically in psychomotor speed and sustained attention.
May signal early cognitive effects in young male smokers; hypothesis-generating and should not yet change practice.
Background: Cigarette smoking represents a considerable public health burden globally. Smoking in older adults is associated with cognitive impairment and more rapid age-associated cognitive decline, but there is a paucity of studies in younger people. Hence, the study was undertaken to know the effect of cigarette smoke on cognitive functions in young healthy adults. Aims and Objectives: The aim of the study was to assess and to compare the cognitive performance in young adult smokers and non-smokers. Materials and Methods: Study was conducted between 30 male smokers (study group) and age, body mass index and education level matched (1830 years) 30 male non-smokers (control group) based on inclusion and exclusion criteria. Subjects of both groups answered a self-reported questionnaire about smoking and personal history. Cognitive tests were done for both the groups, scores tabulated and analyzed. Results: Study group showed a significant reduction in psychomotor speed (P < 0.001) and sustained attention (P < 0.001) but no significant changes in executive functions as compared to subjects in the control group. Conclusion: Prevention of early cognitive decline in smokers has to be the top priority so as to reduce the public health burden. Awareness has to be created among smokers about the neurotoxic effects of cigarette smoke and increased risk of cognitive impairment. [Natl J Physiol Pharm Pharmacol 2019; 9(6.000): 562-565]

Pushpa et al. (2019) conducted an observational in Healthy adults (n=60). Cigarette smoking vs. Non-smokers was evaluated on Cognitive performance (psychomotor speed, sustained attention, and executive functions) (p=<0.001). Cigarette smoking in young healthy male adults was associated with a significant reduction in psychomotor speed (P<0.001) and sustained attention (P<0.001) compared to non-smokers.
