Overview
The Westlake Longevity Cohort (We-Longevity) is a prospective cohort study among centenarians, nonagenarians, senior citizens and their family members up to three generations living in Lishui, China. The primary aim of this cohort is to characterize the multi-omics molecular characteristics of healthy longevity and their dynamic trajectories. Another aim of We-Longevity is to investigate the association of dietary and lifestyle with the multi-omics molecular characteristics of healthy longevity, and to facilitate the development of personalized nutritional/lifestyle recommendation for the public.
Description
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 are influenced by a variety of factors, such as diet structure, lifestyle, ecological environment, gut microbiome and genetics. At present, the researches on healthy longevity are mainly focused on Drosophila, nematodes and mouse models, and few studies on longevity population. Centenarians and nonagenarians are the best objects to study healthy longevity. However, the multi-omics molecular characteristics and regulatory mechanism of healthy longevity in human are still unclear. There, the present We-Longevity design includes 200 centenarians, 600 nonagenarians, 400 senior citizens. We will determine the fecal/serum metabolome, gut microbiome serum proteome and genome, together with diet, lifestyle and disease information.
