Smoking, Alcohol, and Betel Quid and Oral Cancer : A Prospective Cohort Study

Abstract EN

We aimed to investigate the association between smoking, alcoholic consumption, and betel quid chewing with oral cancer in a prospective manner.

All male patients age ≥18 years who visited our clinic received an oral mucosa inspection.

Basic data including personal habits were also obtained.

A multivariate logistic regression model was utilized to determine relevant risk factors for developing oral cavity cancer.

A total of 10,657 participants were enrolled in this study.

Abnormal findings were found in 514 participants (4.8%).

Three hundred forty-four participants received biopsy, and 230 patients were proven to have oral cancer.

The results of multivariate logistic regression found that those who smoked, consumed alcohol, and chewed betel quid on a regular basis were most likely to develop cancer (odds ratio: 46.87, 95% confidence interval: 31.84–69.00).

Therefore, habitual cigarette smokers, alcohol consumers, and betel quid chewers have a higher risk of contracting oral cancer and should receive oral screening regularly so potential oral cancer can be detected as early as possible.
