简要总结
The COcoa Supplement and Multivitamin Outcomes Study (COSMOS; NCT02422745) is a randomized clinical trial of cocoa extract supplement (containing a total of 500 mg/d flavanols, including 80 mg. (-)-epicatechins), and a standard multivitamin supplement to reduce the risk of cardiovascular disease and cancer among men aged 60 years and older and women aged 65 years and older. This ancillary study is being conducted among participants in COSMOS and will examine whether the cocoa extract supplement or the multivitamin supplement has an anti-aging effect (epigenetic aging and inflammaging) and examining these findings in the context of CVD risk factors and outcomes.

结局指标
主要结局
Inflammaging
时间窗: 2 years
An index constructed using several inflammation markers reflecting inflammaging.
Epigenetic age acceleration
时间窗: 2 years
A cumulative epigenetic aging index (DNAm age) that predicts DNAm age will be calculated. The residual from regressing DNAm age on chronological age provides a measure of epigenetic age acceleration.
次要结局
- Pulse wave velocity(2 years)
- Body mass index(2 years)
- Blood pressure(2 years)
