1-6 kopjes koffie per dag verlagen suikerziekte type 2

Research Question:
Drinking coffee lowers the chances of getting diabetes type 2?

Study Design:
This overview article contained 28 prospective cohort studies with participants, of which 45335 1109272 people with diabetes type 2. The follow-up duration (the duration of the study) ranged between 10 and 20 years.

Results and conclusions:
The researchers found that drinking 1 cup of coffee a day, the chance of getting type 2 diabetes significantly with 8% [RR = 0.92, 95% CI = 0.90-0.94] reduced.

The researchers found that drinking 2 cups of coffee per day, the chances of getting type 2 diabetes significantly with 15% [RR = 0.85, 95% CI = 0.82-0.88] reduced.

The researchers found that drinking 3 cups of coffee a day, the chances of getting type 2 diabetes significantly with 21% [RR = 0.79, 95% CI = 0.75-0.83] reduced.

The researchers found that drinking 4 cups of coffee a day, the chances of getting type 2 diabetes significantly with 25% [RR = 0.75, 95% CI = 0.71-0.80] reduced.

The researchers found that drinking 5 cups a day, the chances of getting type 2 diabetes significantly with 29% [RR = 0.71, 95% CI = 0.65-0.76] reduced.

The researchers found that drinking 6 cups of coffee a day, the chances of getting type 2 diabetes significantly with 33% [RR = 0.67, 95% CI = 0.61-0.74] reduced.

The researchers found that each increase with 1 cup of caffeine-containing coffee, the chances of getting type 2 diabetes significantly with 9% [RR = 0.91, 95% CI = 0.89-0.94] reduced.
Significant is, there is a link at a 95% reliability.

The researchers found that each increase with 1 cup of decaffeinated coffee, the chances of getting type 2 diabetes significantly with 6% [RR = 0.94, 95% CI = 0.91-0.98] reduced.

The researchers concluded that drinking coffee (with or without caffeine) the chances of getting diabetes type 2 reduced. The reduced risk was dose-dependent.
