BP1SYS (BP1SYS)
First blood pressure measurement: Systolic

BP1SYS is a 3-digit numeric variable.

Codes

995 = Refused
996 = Technical problems
997 = Other
998 = Missing
999 = NIU (not in universe)

Description

For women who agreed to have blood pressure measured during the survey, BP1SYS reports the woman's first systolic pressure measurement.

The related variable BP1DIA reports the woman's first diastolic 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 BP2SYS and BP3SYS report the second and third systolic measurements taken during the survey, while BPAVGSYS reports the average of the woman's systolic measurements taken throughout the survey.

Comparability

Apart from universe differences, BP1SYS has no comparability problems.

Comparability - Standard DHS

BP1SYS is a country-specific variable, and it is not included in any phase of the standard DHS questionnaire.
