The study, part of KMI’s “Health Big Data Series,” analyzed medical check-up data from about 3 million individuals screened at eight centers across South Korea and compared health outcomes by smoking type and cumulative exposure measured in pack-years, a metric defined by the National Cancer Institute.



Among men, metabolic syndrome prevalence increased from 21.5% in non-smokers to 29.9% in current smokers, reaching 31.2% among conventional cigarette users and 30.8% among dual users. Among women, overall prevalence was 10.7% among non-smokers and 12.6% among current smokers. By smoking type, the rate reached 15.8% among conventional cigarette users and 12.1% among dual users.



Risks also rose with cumulative exposure, climbing to 36% among men with more than 20 pack-years of smoking and 22% for women. Lung function impairment was recorded in 23.4% of men and 21.5% of women, rising sharply among heavy smokers. The study also found smoking patterns shifting, with the share of male lifetime non-smokers rising from 36.7% in 2022 to 39.7% in 2025, while e-cigarette-only use increased from 7.8% to 10%. Researchers noted the findings are based on anonymized screening data and may not fully represent the national population.The post KMI Study Examines Lung Risks and Smoking Habits first appeared on Tobacco Reporter.
