title: Migration and biocultural adaptation: Samoans in California.
abstract: The consequences of migration for the Samoan population of California are discussed within the context of other studies focusing on Samoan native and migrant populations in Samoa and Hawaii. The social, cultural and economic characteristics of California Samoans are described and data are presented for body morphology, blood pressure, psychosocial stress and social support, general morbidity patterns and mortality rates for 1978-1982. Although the nature of disease risks appear profound in this population, particularly patterns of extreme obesity and psychosocial stress, mortality rates for heart disease and stroke are less than might be expected among other American groups. Such unexpectedly low mortality rates may represent the relatively healthy experience of older cohorts of migrants, or be a result of proportionally few individuals having lived long enough in California to develop cardiovascular and other chronic disease that have lengthy natural histories. We postulate that at present Samoan social structure, particularly the high status that accrues with aging in traditional Samoan society, may act as a buffer for the risk factors we observed and their expected outcomes. If so, the U.S.-born Samoans who are currently passing through childhood and early adult years with progressively less awareness of Samoan values of family and social structure will exhibit the same risks we describe here, but lack the available social buffers that currently exist for their parents.
