The main objective of this pre-experimental study is to describe the relationship between gut microbiota and changes in the degree of frailty in older adults who participated in an educational program. More specifically, the study aims to: determine the gut microbiota profile of community-dwelling older adults, both robust and frail; analyze the effect of a 12-month educational program on gut microbiota; examine the association of gut microbiota with physical function, functional dependency, and physical activity in frail or pre-frail older adults who received the program; investigate its relationship with the risk of malnutrition; relate the gut microbiota profile to quality of life, depressive symptoms, and social support; and, finally, associate gut microbiota with cognitive frailty and sleep quality in this group of older adults who participated in the health promotion educational intervention.
