Associations between occupational physical activity and left ventricular structure and function over 25 years in CARDIA
Authors' conclusion
The paradoxically adverse association of OPA with cardiovascular health was partially supported by null or adverse associations between high OPA and echocardiogram outcomes.
Study context
- Population
- CARDIA participants aged 30.4 ± 3.4 years at baseline (Year 5 exam, 1990–91); 50.0% female, 56.4% White
- Participants
- 1,462 participants
- Exposure
- 25-year occupational physical activity (OPA) trajectories
- No OPAn = 770reference
- Medium OPAn = 410
- High OPAn = 282
- Outcome
- Left ventricular (LV) structure and function by echocardiography (LVMi, LVEDVi, LVESVi, LVEF, LVSVi, EA ratio), adjusted for baseline values, demographic/health characteristics and leisure time physical activity (LTPA)
- Follow-up
- 25 years
