RT Journal Article SR Electronic T1 Diet, alcohol, body mass, and social factors in relation to blood pressure: the Caerphilly Heart Study.

These included age, smoking, exercise, and social class. For men not on antihypertensive treatment (n = 356) regression analysis showed that age (p less than 0.001), BMI (p less than 0.05), and alcohol intake (p less than 0.01) were significantly related to systolic blood pressure, and BMI (p less than 0.001) and alcohol intake (p less than 0.01) to diastolic blood pressure. In addition, protein intake (p less than 0.05) was significantly and inversely related to the risk of being hypertensive, but other dietary variables were not related to blood pressure. For men on antihypertensive treatment (n = 31) significant inverse correlations were observed between diastolic blood pressure and the intakes of potassium (p less than 0.01), fibre (p less than 0.001), polyunsaturated fat (p less than 0.01), and a number of other dietary variables. Reasons for these differences are discussed.
