On the intestinal microbiota, you can accurately predict life expectancy


Scientists from Finland took advantage of the detailed data of the Finnish population medical examination according to Finrisk, as well as new machine learning technologies in order to identify a specific connection between microbiota and senile diseases. And they found that the risk of human death can be predicted in more than ten years to analyze the composition of the intestinal microflora.

Specialists from the University of Turku studied samples of feces of 7211 adults collected in 2002, as well as data on the state of their health over the next 15 years. And applied machine learning algorithms to search for types of microbes that correlate with death in the long run. A clear connection was discovered between microbes from the family of enterobacteria and an increased risk of death from gastroenterological and respiratory reasons.

Scientists have not yet for the first time note the correlation of an increased amount of enterobacteria with intestinal cancer and inflammatory bowel disease. However, still not established whether this relationship is causal,

Niiranhen also noted that the data used in this study, «for the first time, make it possible to study the long-term effect on the health of the human intestinal microbiota.»

The authors caution from too hasty conclusions and emphasize that they are far from the development of a test predicting the proximity of death. Before Microbiota can become a tool for predicting life expectancy, it is necessary to conduct careful research, they emphasize. However, this is the first study that points to the connection of microbiota composition with a lifetime.
