Overview

Cross-sectional survey explores links between physical activity, sedentary behavior, and mild cognitive impairment in older adults, indicating important health implications.

Key Points

  • The study investigates the relationships between physical activity levels, sedentary time, and mild cognitive impairment in older adults.
  • Conducted a cross-sectional survey in community settings involving 1,465 older adults.
  • Cognitive function assessed using the Montreal Cognitive Assessment (MoCA).
  • Physical activity levels measured using the International Physical Activity Questionnaire-Short Form (IPAQ-SF).
  • Logistic regression models analyzed associations between physical activity, sedentary time, and mild cognitive impairment.
  • Restricted cubic spline analysis explored dose-response relationships.
  • Higher physical activity levels in the second and fourth quartiles were linked to significantly lower MCI risk (OR = 0.544 and OR = 0.345, respectively).
  • Lower sedentary time in the second quartile also correlated with reduced MCI risk (OR = 0.561).
  • The cognitive benefits peaked at about 1,485 MET-min/wk. of physical activity.
  • MCI risk began to rise when physical activity surpassed 4,000 MET-min/wk., and sedentary time over 200 min/day increased the risk.
