Definition
For women who agreed to have blood pressure measured during the survey, BP3DIA reports the woman's third diastolic pressure measurement.
The related variable BP3SYS reports the woman's third systolic pressure measurement.
In the surveys that measured a woman's blood pressure, the interviewer measured the person's blood pressure at three different times during the survey. Because blood pressure measurements only represent an instantaneous value, the average of multiple measurements may provide more accurate results. The related variables BP1DIA and BP2DIA report the first and second diastolic measurements taken during the survey, while BPAVGDIA reports the average of the woman's diastolic measurements taken throughout the survey.
