Racial Variation in Serum Uric Acid Concentration in Pregnancy: a Comparison between European, New Zealand Maori and Polynesian Women

A prospective study was undertaken to measure serum uric acid levels in normal pregnant women of different races, to ascertain if there was any significant interracial variation. A total of 48 women were studied of which 13 were European, 11 New Zealand Maori, 22 Pacific Islanders and 2 Indian. In the second trimester, European, Maori and Cook Island women had similar uric acid levels and other Polynesian groups showed significantly higher levels. In the third trimester, both Maori and Cook Island women showed a marked rise so that their levels came to equal those of other Polynesian groups, all 3 having significantly higher levels than European women. The importance of these observations relates to the use of uric acid levels in the management of patients with gestational proteinuric hypertension. It is possible that in these cases unusually high results may alarm the clinician into hasty intervention.
