Abstract
Background
Cardiovascular risk factors represent an important health issue in older adults. Previous findings suggest that meditation training could have a positive impact on these risk factors. The objective of this study was to investigate the effects of an 18-month meditation-based intervention on cardiovascular health.
Methods
Age-Well was a randomized, controlled superiority trial with blinded end point assessment, including community-dwelling cognitively unimpaired adults 65 years and older enrolled between November 24, 2016, and March 5, 2018, in France. One hundred and thirty-four participants were included in this secondary analysis. Participants were randomly affected to an intervention group that received an 18-month meditation-based program or to comparison groups (active control group i.e. non-native language training or passive control group i.e. no intervention). The main outcome was change in the Framingham Risk Score (FRS); other outcomes were changes in cardiovascular and metabolic risk factors.
Results
There was no difference in FRS change after 18 months between trial arms (p = .38). When assessing individual cardiovascular or metabolic risk factors, meditation training was associated with a greater reduction in diastolic blood pressure than the comparison group in participants with intermediate to high cardiovascular risk (FRS > 10%) at baseline (p = .03).
Conclusion
An 18-month meditation training was not effective to increase overall cardiovascular health in older adults, but improved diastolic blood pressure in a subgroup analysis including at-risk participants. These results suggest a potential benefit of a long-term meditation intervention in older adults at-risk of cardiovascular diseases, and highlights the need for future research in more targeted populations.
