Figure 2. Relationship between daily walking activity and brain volume.
A. Greater total daily walking activity was associated with larger hippocampal volume (adjusted for intracranial volume; ICV) in women. Associations remained significant for low-intensity daily walking activity, and after adding covariates exercise, moderate- to vigorous-intensity daily walking activity, age, years of education, body mass index (BMI), cardiovascular disease burden, and Mini Mental State Exam (MMSE).
B. Total daily walking activity was not significantly associated with thalamus volume in women.
