Hypothesis
Sugary soda consumption is associated with albuminuria, a sensitive marker for kidney disease.
Conclusion
Sugary soda consumption may be linked to kidney damage, especially in women and those with lower body weight.
Supporting Evidence
- 11% of participants had albuminuria, and 17% consumed 2 or more sugary soft drinks per day.
- The odds ratio for albuminuria associated with sugary soda consumption was 1.40 after adjusting for confounders.
- Women showed a stronger association with an odds ratio of 1.86 compared to men.
- Participants with a BMI under 25 kg/m2 had an odds ratio of 2.15 for albuminuria with high sugary soda consumption.
Takeaway
Drinking a lot of sugary sodas might hurt your kidneys, but having just one or none seems okay.
