The objective of WeF2 is to characterize the long-term stability and dynamics of the gut and oral microbiota in the same cohort across multiple timescales, and to determine whether the day-to-day variability patterns observed at baseline persist over months and years. Participants who completed the WeF baseline protocol will be invited to attend periodic follow-up visits for low-frequency biospecimen collection and to repeat the original 15-day high-frequency sampling protocol at planned intervals, beginning approximately six months after the WeF baseline and continuing at extended intervals thereafter. By combining sparse routine sampling with recurring high-density sampling windows, the study aims to distinguish the stable core microbiome from transient and seasonal fluctuations, to track gradual community shifts under free-living conditions, and to further explore relationships among microbiome dynamics, dietary intake, and host glycemic regulation over an extended observation period.",[26,27],"Health Adults","Stability of Microbiome",[29],"Microbiome","RECRUITING","2026-05-19",{"date":33,"type":34},"2026-05-26","ACTUAL",{"date":36,"type":22},"2026-05-08",{"date":38,"type":22},"2030-12-31",{"name":40,"class":41},"Westlake University","OTHER",1,{"id":44,"slug":45,"hasResults":11,"nctId":46,"briefTitle":47,"officialTitle":47,"acronym":48,"eligibilityCriteria":15,"healthyVolunteers":16,"sex":17,"minAge":18,"maxAge":19,"enrollmentInfo":49,"targetDuration":4,"studyType":23,"phases":4,"briefSummary":50,"conditions":51,"keywords":52,"overallStatus":30,"whyStopped":4,"lastUpdateSubmitDate":53,"lastUpdatePostDateStruct":54,"startDateStruct":56,"completionDateStruct":58,"leadSponsor":60,"locationsCount":42},"100628365","westlake-frequent-sampling-cohort-100628365","NCT07460687","Westlake Frequent-sampling Cohort","WeF",{"count":21,"type":22},"This intensive longitudinal study investigates the day-to-day stability and natural fluctuations of the gut microbiome in healthy adults over a 15-day period.
