According to recent Yale group study by team of Nicola Santoro, M.D,, intestinal bacterial composition in obese children and teenagers is different from that of normal children and adolescents. The study was published September 20, 2016 in the Journal of Clinical Endocrinology and Metabolism.

The percentage of childhood obesity has steadily increased in recent decades. Globally, over 17% of children and adolescents are suffering from obesity. Consequently, this group wanted to reveal the correlation between obesity and intestinal bacteria.

What they did in this study is that they measured body weight and collected intestinal bacteria of 84 children and teenagers. And they also examined eating habit patterns of the subjects.

The researchers found that eight groups of intestinal bacteria were involved in the body fat production and those microbiotas were more common in obese children and adolescents. Bacteria in obese people have been shown to break down carbohydrates more effectively, which has been shown to play a role in producing a lot of fat in the body. The researchers also found that short-chain fatty acids were more likely to be produced in obese children. This short-chain fatty acid affects to increase fat tissue in liver beyond childhood stage.

Nicola Santoro, M.D in Yale University indicates that our finding show children and teenagers with obesity have different categories of bacteria in their intestine and this suggests that specific therapeutic strategies to the obesity microbiotas could be help to prevent or treat obesity in youth.
