About

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.

Full description

This non-randomized pre-experimental study was conducted in the province of Cádiz, Spain. A total of 14 older adults participated, all of whom had previously taken part in the intervention group of the randomized experimental project called Fragsalud, which aimed to improve frailty through educational sessions. During that project, frailty was assessed using the Fried criteria, and physical condition, physical activity, and sleep were evaluated through accelerometry, as well as questionnaires on nutritional habits, depressive symptoms, social support, instrumental and basic activities of daily living, quality of life, cognition, and sleep, at the beginning of the study, at 6 months, and at the end of the study at 12 months. For the Fragbiota project, once Fragsalud was completed, participants were analyzed based on whether or not they responded to the educational intervention. That is, the gut microbiota of those subjects who, after 12 months, had reduced the Fried frailty criteria was compared with those who, despite receiving the educational intervention, had maintained the same Fried levels or had worsened. Furthermore, this gut microbiota was related to the secondary variables previously assessed in the Fragsalud project. This study complied with biomedical ethical guidelines, including Good Clinical Practice (CPMP/ICH/135/95), the Oviedo Convention, the Universal Declaration of Human Rights, CIOMS/WHO ethical guidelines, and the Declaration of Helsinki, ensuring the dignity, rights, and safety of participants. Additionally, participants provided informed consent after receiving detailed explanations, both in writing and verbally, regarding the objectives, procedures, and risks of the study.

Trial design

14 participants in 1 patient group

Older adults who participated in an educational intervention program called FRAGSALUD

Description:

Participants who, after taking part in an educational intervention of a project called FRAGSALUD, either were considered as responders or non-responders to the intervention, measured if they could reduced their levels of Fried's frailty criteria.

Treatment:

Other: Fecal sample collection
