STUDY BACKGROUND INFORMATION AND RATIONALE
The human intestinal tract harbors a diverse and complex microbial community, known as gut microbiota, which is critical in sustaining physiology, metabolism, nutrition and immune function. Imbalance of gut microbiota (dysbiota) has been linked with obesity, hyperglycemia, hyperlipidemia, hypertension, inflammatory bowel disease and other chronic inflammatory diseases. Gut microbiota is affected by host genetic makeup, diet and lifestyle; and therefore varied by human races and geographical locations
This study aims at understanding the structure and characteristics of the gut microbiota and their epidemiological and health correlations in the general population in different geographical locations.
