REGRESSION ANALYSIS OF CHANGES IN BLOOD PRESSURE WITH ORAL CONTRACEPTIVE USE

摘要: Hypertension Detection and Follow-up Program data on 927 women who were surveyed 3 times in 1973-78 premenopausal not pregnant taking antihypertensive medication analyzed to determine the relationship between oral contraceptive (OC) use blood pressure. Mean systolic pressures consistently higher OC users that nonusers with an average difference of 2.3 mmHg.
