Physical activity is associated with better global cognition and frontal function in overweight/obese older adults with metabolic syndrome

Table 2 ANCOVA results of cognitive domain scores (Z scores) by group (regular physical activity vs. no/low physical activity)

Cognitive Domains	No or low physical activity N = 59	Regular physical activity N = 23	Adjusted Difference	P value^*
Global cognition	−0.054 ± 0.53	0·224 ± 0·61	0.254 (0.032 to0.477)	0.026
Frontal function	− 0·075 ± 0·62	0·327 ± 0·70	0.375 (0.110 to 0.639)	0·006
Memory	−0·061 ± 0·78	0·15 ± 0·79	0.192 (−0.174 to 0.558)	0·300
Language	2.884 ± 0·25	2.979 ± 0.25	0.103 (−0.13 to 0.218)	0·080

Data are means ± SD or adjusted means (95% CI)
