Birth certificates and a sample of hospital obstetric records for Indochinese refugees in Santa Clara County, CA, 1979-1980, were reviewed. Among 542 live births, the overall median birthweight of 3175 gm and 5.7 per cent rate of low birthweight were favorable; it is our impression that the more recent arrivals, especially Cambodians and Laotians, present at greater risk, lacking prenatal care, and have more infants of low birth rate and more pregnancy complications.
