Marked ethnic differences in hypertension prevalence have been described in Jewish immigrants to Israel. The extent to which this phenomenon has persisted after a long period of living in the same country, and whether native-born descendants exhibit similar patterns, is not clear. The aim of this study was to determine the prevalence of hypertension in immigrants to Israel and native-born Israelis by region of origin and age at immigration. Complete data were available for 5, 146 subjects (3, 607 men and 1, 539 women) aged 20-64 years who were employed in Israeli industries and were examined during 1985-1987. In both sexes, Jews originating in the West (Europe and the Americas) had higher blood pressures and a significantly higher prevalence of hypertension than those from northern Africa or Asia, particularly in the age group 20-44 years (17% vs. 9% and 8% in men, respectively, and 9% vs. 3% and 5% in women). There was a significant positive association between the prevalence of hypertension and age at immigration (p < 0.001) in both sexes, and this finding was present in all ethnic groups. In multiple logistic regression analysis, the associations of hypertension with ethnic origin and age at immigration were only partly explained by variations in body mass index, after controlling for other potentially confounding variables. These findings suggest that despite these subjects' having shared a relatively similar physical environment for many years, ethnic differences in the prevalence of hypertension persist. Immigration at an older age was associated with a higher prevalence of hypertension for both subjects originating in industrialized countries and those originating in nonindustrialized countries, suggesting that the process of immigration itself may adversely affect blood pressure.
