Definition
For women who agreed to have her blood pressure measured for a second time during the survey, BP3SYS reports the woman's third systolic pressure measurement.
The related variable BP3DIA reports the woman's third diastolic pressure measurement.
In the surveys that measured a woman's blood pressure, the interviewer measured the 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 BP1SYS and BP2SYS report the first and second systolic measurements taken during the survey, while BPAVGSYS reports the average of the woman's systolic measurements taken throughout the survey.
