Climate Vulnerability Index and Incident Type 2 Diabetes in a Large Integrated Health Care System

In this cohort study of 1 003 526 adults, higher community CVI was associated with greater risk of incident T2D independently of traditional risk factors. Linking geocoded CVI to electronic health records may support targeted prevention, risk stratification, and population health planning.
Study context
- Population
- Adults aged ≥18 years without T2D at baseline, with ≥1 outpatient encounter and ≥1 subsequent encounter, June 2016–August 2023, Houston Methodist Learning Health System Registry (Greater Houston, Texas); mean age 50.9 years, 60.4% women
- Participants
- 1,003,526 adults
- Exposure
- Highest vs lowest census tract-level Climate Vulnerability Index (CVI) quartile
- Outcome
- Incident T2D identified by diagnosis codes, antihyperglycemic prescriptions, or HbA1c 6.5% or higher
