Hypothesis
Is there an association between moderate coffee consumption and the prevalence of type-2 diabetes among urban Brazilians?
Conclusion
Moderate coffee intake is associated with a lower prevalence of self-reported type-2 diabetes in the studied population.
Supporting Evidence
- Moderate coffee drinkers (100 to 400 mL/day) had a 2.7% higher prevalence of not having diabetes compared to those drinking less than 100 mL/day.
- High coffee consumers (>400 mL/day) showed no significant difference in diabetes prevalence compared to low consumers.
- The study is the first to show a relationship between coffee drinking and diabetes in a Brazilian population.
Takeaway
Drinking a moderate amount of coffee might help people not get diabetes, but drinking too much coffee doesn't seem to help.
Methodology
A cross-sectional study using telephone interviews to collect data on coffee intake and diabetes status from 1,440 adults.
Potential Biases
The sample was skewed towards women, which may affect the generalizability of the results.
Limitations
The study's cross-sectional design limits the ability to determine causality, and it may not represent the entire population due to telephone access issues.
Participant Demographics
Participants ranged in age from 18 to 89 years, with 67% being women.
