	Children		Adolescents
	Boys	Girls	Boys	Girls
Mean (SD) trips at T1	6.0 (3.7)**, ****	5.2 (4.5)*, ****	12.6 (7.8)	9.8 (7.4)
Mean (SD) trips at T2	7.8 (5.5)****	6.3 (5.1)****	11.3 (7.6)	9.7 (7.0)
Mean (SD) change in trips	1.8 (5.0)***	1.1 (4.4)	−1.3 (7.6)	−0.1 (6.6)

*p < 0.05, **p < 0.01: paired samples t test—significant differences between trips at T1 and T2 by sex within age group; ***p < 0.01, ****p < 0.001: independent samples t test—significant differences between age groups within sex
