Smoking cessation improves health status of patients with chronic diseases: evidence from a longitudinal study of older adults in China

This research provides evidence highlighting the favorable health ramifications associated with smoking cessation in elderly individuals with chronic illnesses. Noteworthy improvements in both subjective health assessments and blood-based markers were observed post-smoking cessation, with benefits becoming more prominent with prolonged abstinence. These results underscore the vital importance of smoking cessation in the holistic care of chronic conditions and broader health enhancement endeavors. Further validation of these findings through an extended follow-up period is anticipated to bolster these conclusions with increased confidence.
