Effect of Dietary Fiber Supplement on the Intestinal Microbiota Among Schizophrenia Patients
The Effect of Dietary Fiber Supplement on the Intestinal Microbiota Among Schizophrenia Patients With Central Obesity: a Pilot Study
Background There has been much interest in the relationship between the types of gut microbiota and the development of obesity in recent years. It has been reported that the proportions of Firmicutes and Bacteroidetes differ between obese and normal weight human subjects. Human intestinal microbiota compositions have been found to be associated with long-term dietary habits and lifestyle. However, an increasing number of researches show that intestinal microbiota composition may be affected after short-term diet intervention. Importantly, obesity and metabolic problems play important roles in morbidity and mortality of schizophrenia patients. Human intestinal microbiota compositions related with obesity may impact the heath of this population. Therefore, we searched current advances about the connection of obesity, intestinal microbiota compositions, and diet in schizophrenia to conduct a clinical research focus on the effect of high fiber diet on the intestinal microbiota of schizophrenia patients with central obesity.
Method We will investigate in a 4-week intervention whether consumption of dietary fiber supplement(Inulin) affect the microbiota composition in schizophrenia inpatients with central obesity. Fecal samples from participants before and after the intervention will be processed for the microbiota analysis.
