Physical activity mediates age differences in cognition among Tsimane forager-horticulturalists.

ABSTRACT:

Background

The Tsimane and Moseten of the Bolivian Amazon are highly physically active and exhibit low rates of cognitive impairment and brain atrophy.

Methods

We use structural equation modelling to examine how their physical activity levels mediate the relationship between (1) age and cognition, and (2) age and cognition via brain volume (BV).

Results

Tsimane males (n = 305, mean ± SD age = 59.94 ± 9.68) and Tsimane females (n = 265, mean ± SD age = 59.28 ± 9.79) exhibit significantly higher levels of physical activity than Moseten males (n = 106, mean ± SD age = 58.15 ± 9.93) and Moseten females (n = 96, mean ± SD age = 56.63 ± 9.69). Physical activity significantly mediates the relationship between age and cognition in Tsimane males (indirect effect estimate ݼ = -
