From the records of the Health Examination Survey of adults, 1960–62, the blood pressure of each of 6672 subjects was tabulated against his response to several questions on a self-administered medical history form. The responses to questions regarding headache, epistaxis, and tinnitus showed no relation to either systolic or diastolic blood pressure. The occurrence of dizziness was increased only in persons with very high diastolic pressure. The occurrence of fainting was inversely related to blood pressure. Headache, tinnitus, and dizziness were each reported slightly but significantly more often in subjects with than without retinopathy; this relation held true in both normotensive and hypertensive groups.
