Gut microbiome composition in the Hispanic Community Health Study/Study of Latinos is shaped by geographic relocation, environmental factors, and obesity

Analysis of self-collected stool samples from 309 participants demonstrated that proton pump inhibitor use is significantly associated with an enrichment of Streptococcus species in the gut. This confirms the suitability of decentralised self-sampling for conducting large-scale metagenomic analyses in population studies.

The study demonstrated the feasibility of a fully decentralised design by successfully recruiting 37 participants and completing follow-up for self-collected stool samples without requiring on-site visits.

This pilot study found that mailing self-collection kits to endometrial cancer survivors was feasible and acceptable, whilst also observing that chemotherapy or radiation reduced beneficial vaginal bacteria compared to surgery alone.

Taxonomic and diversity profiles differed between unstabilised swabs and stabilised OmniGene kits, with transport time disproportionately affecting swab samples; the collection method had a greater impact on taxa and diversity than transport time, highlighting the need for standardised stool collection in decentralised microbiome studies.

In a one-week virtual home clinic with 134 participants, 86 per cent returned saliva and 84 per cent returned stool, and most components were feasible and acceptable despite device and logistical challenges. This supports decentralised, patient-centric self-collection of non-blood biospecimens for research.
