The finding further suggests the odds of lower cognitive scores among older adults who were smokers (OR \u22120.53; 95%CI \u22120.87 to \u22120.19) and smokeless tobacco users (OR \u22120.22; 95%CI \u22120.43 to \u22120.01) as compared to never tobacco users.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Interventions designed to prevent the incidence of cognitive impairment should focus on limiting the use of tobacco.

Though tobacco is a risk factor for various diseases including cancer, the extent of its impact on cognitive health among the older population is limited. This study contributes to the existing literature by highlighting poor cognitive outcomes among older adults who smoke tobacco and\/or consume smokeless tobacco as compared to never-tobacco users. Our findings emphasize the need to accelerate programmes related to tobacco-free generation in LMICs to reach a higher quality of life and healthy aging in pursuit of achieving the sustainable development goal of \u201cgood health and well-being.\u201d<\/jats:p><\/jats:sec>","DOI":"10.1093\/ntr\/ntad117","type":"journal-article","created":{"date-parts":[[2023,7,9]],"date-time":"2023-07-09T20:49:06Z","timestamp":1688935746000},"page":"342-352","source":"Crossref","is-referenced-by-count":4,"title":["How Does Tobacco Use Affect the Cognition of Older Adults?
