Background: Diabetes and tobacco use are well-established risk factors for stroke. However, the intersection of prediabetes, tobacco use, and stroke among young individuals remains underexplored. This study aims to investigate the association between pre-diabetes and stroke risk in young tobacco users. Methods: Using the National Inpatient Sample (2019) and relevant ICD-10 codes, we identified young patients with tobacco use disorder and pre-diabetes. Regression analysis considered risk factors (gender, demographics, income, comorbidities) to assess stroke odds. Results: Among 1,017,540 stroke hospitalizations, 1.9 % were pre-diabetic. Pre-diabetics were often older (median age 36 vs. 31), male (59.4 %), Black (33.8 %), and Hispanic (12.2 %), with higher rates of comorbidities, including drug abuse, alcohol abuse, COPD, and CKD (p < 0.001). They also exhibited higher rates of stroke events (1.9 % vs. 0.5 %, p < 0.001). Multivariable analysis after adjusting for confounders, young metabolically healthy smokers with pre-diabetes had a higher risk of stroke (aOR 3.31, 95 % CI [1.67–6.55], p < 0.001). Conclusion: Prediabetes could potentially triple stroke risk in young tobacco smokers. Prospective research is warranted to explore the causal association between pre-diabetes and stroke in the setting of tobacco use. |
