Prevention & lipidsCohort study
Dietary carbohydrate quality, fibre-rich food intake, and left ventricular structure and function: the CARDIA study
- Prospective cohort study
Authors' conclusion
Higher quality of CHO and intake of fibre-rich foods were favourably associated with LV structure and function.
Study context
- Population
- CARDIA participants; diet at exam years 0, 7 and 20, echocardiography at years 25 and 30
- Participants
- 3,171 participants
- Exposure
- Quartiles of CHO quality and of fibre-rich food score
- Outcome
- Cardiac phenotype measures (LV structure and function) by echocardiography
- Follow-up
- Exam years 25 and 30
Main finding
As reported in the abstract
Cardiac phenotypes across quartiles
- CHO quality quartiles favourably associated with left ventricular (LV) mass index
- Ptrend < .001
- CHO quality quartiles favourably associated with global longitudinal strain
- Ptrend < .001
- Fibre-rich food score quartiles favourably associated with LV mass index
- Ptrend < .001
- Fibre-rich food score quartiles favourably associated with LVEF
- Ptrend = .008
- Fibre-rich food score quartiles favourably associated with global longitudinal strain
- Ptrend < .001
- Fibre-rich food score quartiles favourably associated with E/e' ratio
- Ptrend = .02
- Fibre-rich food score quartiles favourably associated with left atrial volume index
- Ptrend = .02
- Effect sizes as % of respective SDs
- between 10% and 26%
Observational data: associations, not effects.
