The FibreGum Study

Is a chewing gum rich in dietary fibre a simple and complementary approach to treat overweight and obese children and adolescents?

According to a study by the Health Promotion Switzerland from 2021/22, about one in six children in Switzerland is affected by overweight or obesity. Obesity is not only a chronic disease in itself, but also a major risk factor for the development of the world's leading causes of cardiovascular disease, various types of cancer, diabetes and osteoarthritis.

Studies have shown that prebiotic dietary fibers are a promising approach to change the composition and function of the microbiota in the gut and mouth. Moreover, they could also enhance weight loss in obesity therapy.

Therefore, we want to investigate this in a study with children and adolescents aged 10-16 years. We are studying whether daily chewing of a food fiber-enriched chewing gum could promote the diversity of the microbiota, at reduce snacking, and thus improve weight control.

Interested children and adolescents (10-16 years, >97th percentile) are welcome to be referred by their family doctor to the obesity consultation at the Bern Children's Hospital. All participants must attend the obesity consultation.
