A dogma of cardiology is that blood pressure (BP) increases with age.1,2 Yet studies of non-Westernized adults from isolated hunter-gatherer peoples have found little evidence of an age-associated rise in BP.3 To date, no studies have recorded BP in children of isolated communities and examined the age-BP association over the entire lifespan, and no studies have compared age-BP association in geographically colocated communities with different levels of Westernization.
