Association between dietary index for gut microbiota and diarrhea among US adults: a cross-sectional analysis of NHANES 2005-2010.

ABSTRACT:

Objectives

Growing attention has been paid to the relationship between the gut microbiota and diarrhea. A recently proposed Dietary Index for Gut Microbiota (DI-GM) reflects the overall dietary quality as it pertains to gut microbiota diversity. However, evidence regarding the association between DI-GM and diarrhea is still lacking. This study aims to investigate the association between DI-GM and the risk of diarrhea.

Methods

A total of 15,590 adults (≥20 years old) from National Health and Nutrition Examination Survey (NHANES) 2005-2010 were included in this analysis. Diarrhea was defined by self-reported common Bristol Stool Form Scale (BSFS) type 6 or 7, or more than three bowel movements per day. DI-GM comprises 14 food/nutrient components known to be associated with gut
