The life-course analysis on childhood (age 4–11) and adolescent (age 11–18) park availability and cognitive change in later life.

Life-course Park Availability a	Change in Cognitive Function from Age 70 to Age 76 b
	All c	Males d	Females d	Low Traffic Accident Density c	High Traffic Accident Density c
Childhood Activity Space * Adulthood Residence	0.22 (−0.07 to 0.51) [0.1475]	0.13 (−0.32 to 0.57) [0.5764]	0.33 (−0.07 to 0.73) [0.1016]	0.52 (−0.08 to 1.13) [0.0877]	0.14 (−0.27 to 0.54) [0.5054]
Adolescent Activity Space * Adulthood Residence	0.27 (0.00 to 0.55) [0.0496]	0.21 (−0.20 to 0.62) [0.3100]	0.33 (−0.07 to 0.72) [0.1022]	0.98 (0.36 to 1.60) [0.0022]	0.08 (−0.29 to 0.45) [0.6677]

^a The park availability is determined using the % of the area within a 1000 m buffer surrounding the home and school and a 200 m buffer surrounding the route to school. ^b Odds Ratio (95% CI) [p-value]. ^c Adjusted for the sex, father’s occupational social class, people per room in the childhood home, childhood smoking, adulthood OSC, alcohol consumption, and smoking status. ^d Adjusted for the father’s occupational social class, people per room in the childhood home, childhood smoking, adulthood OSC, alcohol consumption, and smoking status. * Interaction term.
