Neighbourhood‐level social deprivation and the risk of recurrent heart failure hospitalizations in type 2 diabetes
Authors' conclusion
Social deprivation is associated with increased HFH in T2D with a disproportionate influence in Black patients. Strategies to reduce social disparity and equalize racial differences may help to bridge this gap.
Study context
- Population
- US Veterans with stable T2D without prevalent HF; mean age 67.5 years, 75.7% White
- Participants
- 1,012,351 veterans
- Exposure
- Social deprivation index groups I–V
- Outcome
- Total (first and recurrent) HF hospitalizations, age-adjusted rate per 1000 patient-years
- Follow-up
- 10-year follow-up
Methodological detailsracially diverse cohort, 10-year follow-up, adjusted analyses
- Racially diverse cohort
- 10-year follow-up
- Adjusted analyses
Main finding
As reported in the abstract
Total HFH rate (per 1000 PY) · 10 years
- Total heart failure hospitalizations (HFH) rate, overall cohort
- 54.8 (95% CI: 54.5, 55.2)/1000 patient-years (PY)
- Group V vs group I: higher relative risk of HFH
- 53%
Observational data: associations, not effects.
Further findings
Cumulative incidence of first HFH
Social deprivation index (SDI)–HFH association by race
- Association between SDI and HFH stronger in Black patients
- SDI × Race pinteraction < .001
