In a new study from the University of Turku, researchers found gut microbial signatures which predicted the onset of type 2 diabetes.
They used machine learning techniques to discover if specific signals in the gut microbiome composition were linked to an increased risk of type 2 diabetes.
They identified six bacterial groups from the family Lachnospiraceae and its close relatives which were linked to an increased risk of developing type 2 diabetes.
These bacterial species have been also previously linked with prevalent type 2 diabetes and several other metabolic diseases, such as fatty liver disease.
They also seem to be at least partly linked with the quality of diet.
The results of this study support previous notions on links between adult-onset diabetes, dietary habits, and metabolic diseases, likely modulated by the gut microbiome.
The prevalence of type 2 diabetes is still increasing around the world. The disease has major impacts on quality of life, and it is recognized as a serious and costly public health concern.
Prevention and treatment of adult-onset diabetes are thus highly important research topics.
Previous research has identified several risk factors for type 2 diabetes, such as genetics, lifestyle, and environmental factors.
In the study, the team examined fecal samples collected from a large Finnish population cohort, FINRISK 2002.
Extensive health data from over 5,000 participants were collected during sampling, and the incidence of disease was tracked for nearly 16 years through electronic health records.
The team says the results of this study help us better understand the risk factors of type 2 diabetes and could aid in the development of more effective treatments in the future.
