Increased consumption of caffeine may help reduce the risk of premature death in people with chronic kidney disease (CKD), according to a new study published in Nephrology Dialysis Transplantation.
There is an inverse relationship between coffee consumption and mortality in the General population. Researchers were interested in the question whether the consumption of caffeine and mortality in people suffering from chronic kidney disease.
The possible protective effect of caffeine allegedly linked with action at the level of the vessels. Caffeine is known to promotes the release of nitric oxide, which occurs due to the expansion of blood vessels and improves their functioning.
Increase the risk of premature death due to chronic kidney disease is very actual problem, because it is expected to increase its prevalence throughout the world. Today approximately 14% of the adult population of the United States have CKD.
The researchers suggested that caffeine consumption may be associated with lower mortality among participants with chronic kidney disease. They examined data 4863 American adults observed in the period from 1999 to 2010.
Scientists have identified the main characteristics of the consumers of beverages containing caffeine (compared to people who consumed fewer of such drinks). It is, as a rule, men, non-Hispanic white, with a higher annual income and education level, current or former smokers, consuming more alcohol and with a history of fewer migrated strokes.
According to the results of the analysis, there was an inverse relationship between caffeine consumption and mortality from all causes among the participants with CKD. At higher levels of caffeine consumption by nearly 25% decreased risk of death (average for 60 months).
Our study showed a protective effect from caffeine consumption among patients with chronic kidney disease. Reduction of mortality was observed even after considering other important factors such as age, gender, race, Smoking, other diseases and diet. These results indicate that recommendations to patients with kidney disease drinking more caffeine can reduce their mortality. It seems simple, clinically effective and inexpensive option, although this benefit should ideally be confirmed by a randomized clinical trial, told Bigote Miguel Vieira (Vieira Miguel Bigote), one of the lead authors of the study.
The research was observational in nature, so the aim was not to prove that caffeine reduces the risk of death in patients with chronic kidney disease, the possibility of such protective effect is only perceived.
