Westlake Longevity Cohort

Aging is a major risk factor for most fatal diseases, such as Alzheimer's disease, type 2 diabetes, cardiovascular disease, and cancer. Global population aging is becoming increasingly serious, and this trend is mainly driving the annual increase in the prevalence of aging-related diseases. Healthy longevity is influenced by a variety of factors, such as diet structure, lifestyle, ecological environment, gut microbiome, and genetics. At present, research on healthy longevity is mainly focused on Drosophila, nematodes, and mouse models, but few studies have targeted longevity populations. Centenarians and nonagenarians are the best populations to study healthy longevity. However, the multi-omics molecular characteristics and regulatory mechanisms of healthy longevity in humans are still unclear. Therefore, the We-Longevity design includes centenarians, nonagenarians, and senior citizens. We will determine the fecal/serum metabolome, culturable gut microbiome characteristics, gut microbiome, serum proteome, and genome, together with diet, lifestyle, and disease information.
