The results of a population-based study of blood pressure and related variables of 203 female migrants and their female progeny from the Punjab State, India, now living in Southall, London, were compared with data from a similar survey made in 1976 of females then living in the Punjab. This comparison yielded the following information: The age-adjusted prevalence of hypertension by WHO criteria (160/95 mmHg.) was 23% in the migrants to Southall compared with 1.4% in the Punjab natives. There were significant increases in blood pressure levels with increasing age in both migrants and natives, but the migrants' pressure were higher at almost all ages than the natives'. The migrants were on average 10 kg. heavier than their native counterparts, and measures of obesity (Quetelet Index) were strongly related to blood pressure elevation after age was controlled. After age was considered, diastolic blood pressure was significantly correlated with time in England and educational attainment of the migrants.
