The third measurement of blood pressure is given in the IR file by s1056a and s1056b.

Both women and men had their blood pressure measured three times. Each time they were asked for permission for taking another BP measurement. If consent was not given for the second or third measurement, we had a code to record that. The second and third measurements then had to be averaged and reported back to the respondent. If there were only two measurements, the second one was used in place of an average. The BP distribution and high BP prevalence are based on the averaged BP ( plus information on taking meds for those with the normal BP).
