title: Is Intelligence in Early Adulthood Associated With Midlife Physical Performance Among Danish Males?
abstract: OBJECTIVE
  Insights into the causes of variances in physical performance are important to prevent mobility limitations in old age. We examined associations between intelligence in early adulthood and midlife physical performance.
  
  
  METHODS
  Data from the Copenhagen Aging and Midlife Biobank were analyzed using linear regression. In total, 2,848 male cohort members had intelligence scores from conscription and physical performance measures from midlife.
  
  
  RESULTS
  In adjusted models, a 1 SD increase in intelligence resulted in 1.10 more chair-rises (p < .001), a 1.03 cm higher jump (p < .001), a 3.69% smaller balance area (p < .001), a 0.71 kg increase in handgrip strength (p < .001), and a 5.03 N increase in back force (p < .001). Results for flexibility and abdominal force were not significant.
  
  
  CONCLUSIONS
  Public health interventions should focus on addressing people with different cognitive abilities and bear in mind that prevention of mobility limitations might need to start early in life.
