Hypothesis
Is habitual betel quid chewing a risk factor for biochemical dysfunction and cirrhosis of the liver?
Conclusion
Betel quid chewing, along with other factors like alcohol consumption and viral infections, is associated with liver dysfunction in the Atayal Aboriginal community.
Supporting Evidence
- Overall prevalence rates for hepatitis B surface antigen (HBsAg) and hepatitis C virus (HCV) were 21.2% and 2.9%, respectively.
- Aboriginal participants showed higher proportions of smoking, alcohol drinking, and betel quid chewing compared to non-Aboriginal.
- 41 cases of liver cirrhosis were detected among 1,382 subjects who underwent abdominal ultrasonography.
Takeaway
This study found that chewing betel nut and drinking alcohol can hurt your liver, especially for the Atayal Aboriginal people.
Methodology
The study involved 3,010 adults from the Atayal Aboriginal community, using abdominal ultrasonography to diagnose liver cirrhosis and blood tests for hepatitis markers.
Potential Biases
Potential misclassification of alcohol consumption, smoking, and betel quid chewing due to reliance on self-reported data.
Limitations
The study's cross-sectional design limits causal inferences, and self-reported behaviors may lead to misclassification.
Participant Demographics
Participants included 2,063 Atayal Aboriginal and 947 non-Aboriginal adults, with an average age of 49.8 years and 48% male.
