| Description: |
Introduction The health implications of electronic cigarette (e-cigarette) use remain uncertain despite their increasing global prevalence. This study evaluates the health hazards of e-cigarettes on railway workers by comparing the differences in clinical and biochemical health indicators resulting from exposure to different smoking methods. Methods Using a retrospective cohort design, this study analyzed 7719 routine physical examinations and clinical health records from male railway workers in Shanghai (March 2022). Participants were stratified into four smoking subgroups: non-users, e-cigarette users, cigarette smokers, and dual users (concurrent e-cigarette and cigarette use). A multinomial logistic regression analysis evaluated the potential health impacts associated with each type of cigarette use, while a linear regression analyzed the impact of accumulated smoking years on these health indicators. Results E-cigarette use was associated with increased odds of elevated systolic blood pressure (AOR=1.12; 95% CI: 1.01–1.24; AOR=1.18; 95% CI: 1.06–1.31) and heart rate (AOR=1.18; 95% CI: 1.06–1.33) per 10-unit increase, as well as reduced urine pH (AOR=0.64; 95% CI: 0.52–0.80; AOR=0.70; 95% CI: 0.56– 0.88) compared to non-users and cigarette smokers. Compared to cigarette use, e-cigarette use was associated with higher hemoglobin levels (AOR=1.22; 95% CI: 1.05–1.42) and increased aspartate aminotransferase levels for every 10-unit increment (AOR=1.23; 95% CI: 1.01–1.51). Furthermore, relative to non-users, e-cigarette users showed higher levels of white blood cells and carcinoembryonic antigen, with the largest effect sizes observed among e-cigarette users compared to other subgroups. In addition, the number of accumulated smoking years significantly impacted clinical and biochemical health indicators in both cigarette and e-cigarette users. Conclusions E-cigarette use was associated with adverse alterations in several clinical and biochemical health indicators, some of which were comparable to or more ... |
