Thus, population aging in the United States may have catastrophic results if interventions are not found and implemented. This study examines possible associations between cognitive impairment and exercise, cognitive activities, and socialization. Cognitive activities, socialization, and exercise were assessed at baseline, and cognitive function was measured at baseline, 5-year, and 10-year follow-up. Controlling for baseline cognitive function, age, sex, education, diabetes, and hypertension, linear regression was performed. Engagement in cognitive activities was inversely associated with the onset of cognitive impairment at 5-year follow-up but was no longer significant at 10-year follow-up. Exercise was associated with a lower risk of cognitive impairment at 10-year follow-up but was not significant at 5-year follow-up. Associations with socialization were not statistically significant at either follow-up.<\/jats:p>","DOI":"10.1177\/1533317513518646","type":"journal-article","created":{"date-parts":[[2014,1,9]],"date-time":"2014-01-09T20:55:35Z","timestamp":1389300935000},"page":"372-378","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":46,"title":["The Impact of Exercise, Cognitive Activities, and Socialization on Cognitive Function"],"prefix":"10.1177","volume":"29","author":[{"given":"M.
