Size of study:
1,260 adults ages 60-77
Researchers randomly assigned 1,260 people ages 60-74 into two groups – intervention and control. They then subjected the intervention group to 2 years of a lifestyle modification plan. The people in the intervention group that showed the most benefit to cognition, especially executive function, from the lifestyle intervention statistically had shorter telomere lengths at baseline. Researchers conclude that since short average telomere length is a risk factor for dementia, that lifestyle interventions can be a mitigating factor in a high risk population.
