Coffee reduces death risk in chronic kidney disease patients

About 89 per cent of the adult USA population consumes caffeine daily. The researchers hypothesized that caffeine consumption including Coffee might be associated with lower mortality among participants with chronic kidney disease.

In the study data from 4,863 American people observed from 1999 to 2010 was analysed. As compared with people who consumed a smaller amount of caffeine-containing beverages, caffeine consumers were more likely to be male, non-Hispanic white, with a higher education level and higher annual income.

The results suggest an inverse association between Coffee consumption and all-cause mortality among participants with chronic kidney disease. As compared to people that consumed less caffeine, patients that consumed higher levels of caffeine presented a nearly 25% reduction in the risk of death over a median follow-up of 60 months.

According to Miguel Bigotte Vieira, one of the study's lead authors, "Our study showed a protective effect of caffeine consumption among patients with chronic kidney disease. The reduction in mortality was present even after considering other important factors such as age, gender, race, smoking, other diseases, and diet.

These results suggest that advising patients with kidney disease to drink more Coffee may reduce their mortality. This would represent a simple, clinically beneficial, and inexpensive option, though this benefit should ideally be confirmed in a randomized clinical trial." The author emphasized that this observational study cannot prove that caffeine reduces the risk of death in patients with chronic kidney disease, but only suggests the possibility of such a protective effect.
