Definition
For women who agreed to have blood pressure measured during the survey, BP2DIA reports the woman's second diastolic pressure measurement.
The related variable BP2SYS reports the woman's second 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 BP3DIA report the first and third diastolic measurements taken during the survey, while BPAVGDIA reports the average of the woman's diastolic measurements taken throughout the survey.
