Health of older Chinese seasonal migrants

Official title: Chinese Migrant Population Health Cohort

Run by Harbin Medical University · NCT07124949 · Data updated 2026-11-12

This project will follow older adults who move seasonally between cold Heilongjiang and tropical Hainan to see if their migration patterns affect heart, metabolic, and aging-related health.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are permanent residents of Harbin or Hainan aged 60 or older who seasonally migrate between those regions, can give informed consent, complete questionnaires and exams, and agree to long-term follow-up and biospecimen collection.

Probably not a fit

People with end-stage organ failure, recent life‑threatening acute events, moderate-to-severe cognitive impairment, or on chronic antiviral or antipsychotic therapy are excluded and likely will not benefit from the study findings.

What this trial studies

This is a prospective, multi-center cohort enrolling adults aged 60 and older who seasonally migrate between Harbin (Heilongjiang) and Hainan. Participants undergo standardized baseline questionnaires, physical exams, imaging, and collection of blood, stool, hair, and nail samples, alongside environmental exposure monitoring. The cohort uses periodic in-person reassessments, remote monitoring, and linkage with hospital records for long-term follow-up. The goal is to identify cardiovascular and metabolic risks, underlying biological and environmental mechanisms, and opportunities for prevention in this unique population.

Why it matters

Potential benefit: If successful, the work could lead to tailored prevention strategies and early detection efforts that reduce cardiovascular and metabolic illness among older seasonal migrants.

How similar studies have gone: Some cohort research links migration, climate, and cardiometabolic outcomes, but studying seasonal older migrants across cold and tropical regions is relatively novel with limited prior direct evidence.
