Influence of migration on blood-pressure of Easter Islanders

Abstract

The rate of the rise of diastolic blood-pressure with age increases significantly in the inhabitants of Easter Island when they migrate to the South American continent. Consequently, essential hypertension (which is absent in those who remained on the island) is common among them. The increase of the variance of blood-pressure is produced by the increase of the regression-coefficient of blood-pressure and age, and is directly influenced by migration, regardless of age.
