| Abstract: | Des donnees comparatives sur la pression sanguine systolique et diastolique des Navahos de sexe masculin furent recueillies avant et apres leur emigration d'un milieu rural a un centre urbain. Les deux mesures furent significativement plus elevees apres l'emigration. Quelques facteurs causaux tels que le changement d'altitude, l'ingestion de gras satures et l'age furent elimines. D'un maniere pro-visoire, on conclut que des facteurs associes a l'emigration, tels qu'un changement dans les habitudes de repos, la pollution de l'air ainsi que la separation de la parente sont a l'origine de ces changements physiologiques.
Comparative data on systolic and diastolic blood pressures were obtained on male Navahos before and after migration from a rural to an urban environment. Both measures were significantly higher after migration. Various possible causes - such as change in altitude, saturated fat intake, and age - are eliminated. It is tentatively concluded that altered rest patterns, urban pollution, and separation from kin, i.e., things specific to the act of migration, are causally implicated. |
