Hypothesis
The study investigates the relationship between dietary and serum carotenoids and vitamins and the risk of cervical dysplasia.
Conclusion
Higher serum levels of α-carotene are associated with a decreased risk of cervical dysplasia.
Supporting Evidence
- Higher serum level of α-carotene was significantly associated with decreased risk of cervical dysplasia.
- The odds ratio for the highest tertile of α-carotene compared to the lowest was 0.16.
- Decreased risk for the highest tertile of serum lycopene was marginally significant with an odds ratio of 0.28.
- Decreased risks for the highest tertiles of β-carotene and zeaxanthin/lutein were not statistically significant.
Takeaway
Eating foods with more α-carotene might help lower the chances of getting cervical dysplasia.
Methodology
A case-control study was conducted with 156 women diagnosed with cervical dysplasia and matched controls, measuring serum carotenoids and vitamins.
