Heart attack, stroke, diabetes, and hypertension in West Indians, Asians, and whites in Birmingham, EnglandHypertension is more common in black Americans than whites and is also common in Jamaica.1 2 In Jamaica heart attacks are infrequent, and mortality in blacks in Britain may also be lower.3 The prevalence and complications of hypertension among West Indians in Britain have not yet been systematically examined. After observing that heart attacks seemed unduly uncommon in this group we examined admissions to Dudley Road Hospital over five years and compared rates for heart attack, stroke, hypertension, and diabetes among the three main ethnic groups.Number ( %) of admissions for all causes (excluding obstetrics and gynaecology) compared with heart attack, stroke, diabetes, and hypertension among ethnic groups aged 30 to 59 years during 1974 to 1978 inclusive
SummaryA screening survey was conducted among factory workers, aged 15-64 years, in Birmingham, England to investigate ethnic differences in blood pressure. One-thousand and forty-nine subjects (784 men, 265 women) were screened, representing 79%Xv of the eligible population.Mean systolic and diastolic blood pressures generally did not differ between men of black West Indian (n= 173), local white (n= 439) or Asian (n= 172) origin, when matched by 10-year age groups. Analysis of covariance using age as the covariate revealed that, overall, Asian men had significantly lower systolic but higher diastolic pressures than the other ethnic groups. The proportion of men arbitrarily defined as hypertensive (3 160 mmHg systolic or 395 diastolic or blood pressures below this figure whilst receiving antihypertensive therapy) was 26% of West Indians, 22% of whites and 17% of Asians, but these were not significantly different when age was accounted for.Black West Indian women (n= 101) did have higher diastolic pressure than white women (n= 164), but this difference was dependent on body mass index. Overall, systolic pressures in women were not significantly different.These findings differ from those consistently reported from the United States.
SummaryFour-hundred and twenty-eight school leavers of 3 ethnic groups (white, black and Asian) were screened for blood pressure, resting pulse rate and general anthropometric characteristics. Asian pupils were both shorter and lighter than the other two groups whilst black males were heavier and taller. There was no significant difference in the mean systolic or diastolic blood pressure between the 3 groups, although the black pupils had a stronger family history of hypertension, particularly on the mother's side. These observations differ in some respects from other ethnic blood pressure studies and establish values for the local population.
