Validity and inter-observers reliability of blood pressure measurements using mercury sphygmomanometer in the PERSIAN Guilan cohort study

Objective:
Accurate measuring of blood pressure is a vital step in both clinical and para-clinical settings. The aims of the present study were to evaluate the validity and inter-observer reliability of measured blood pressures by two trained observers and one expert supervisor in the PERSIAN Guilan cohort study (PGCS).
Participants and methods:
In a quasi-experimental study, two trained observers and one expert supervisor measured systolic and diastolic blood pressures (SBP and DBP) in 85 included participants. All measurements were done using Riester mercury sphygmomanometer as duplicate for each people.
Results:
Lack of validity in the total SBP (P = 0.017), DBP in age 25 (P=0.019) of first observer and total SBP (P = 0.045), SBP of male (P = 0.019), both SBP and DBP in age>50 years (P = 0.034, P = 0.012) and DBP in BMI
