Dr. Yeh acknowledged certain limitations of the study, including its modest sample size, the potential for selection bias, and the fact that participants were not blinded to the intervention group. “We were also unable to isolate benefits to either physical activity or meditative components, or to a combination of both,” she said.
The study was funded by the National Center for Complementary and Alternative Medicine. Dr. Yeh said that she had no relevant financial disclosures to report.
