Neðst á síðunni er hægt að nálgast greinina í heild sinni með því að smella á hlekkinn View/Open Background: Today there are mainly three methods for measuring blood pressure, namely by a health worker at the clinic, by self-monitoring (often called home monitoring) and ambulatory monitoring. These methods give different mean values. All present studies concerning the relation between high blood pressure and organ damage are based on blood pressure measurements at clinics, and therefore the predictive values of home and average 24-h ambulatory measurements are not known. Comparative studies on "white coat effect" on blood pressure in Iceland are lacking. Furthermore, the Icelandic people have long working days and therefore some knowledge on blood pressure at work is of interest. The relation between blood pressure at the clinic and at work is unknown Objective: To analyse possible white coat effects of blood pressure and to compare these measurements with blood pressure values at work. Material and methods: During 1993-1994, 84 males aged 25-65 years were allocated to the study from five health centres and two hypertension clinics. Self-measurements of blood pressure were performed on UA-751 Digital Blood pressure Meter at home, at work and at the clinic. All measurements were scheduled between 3 and 5 PM. For comparison with blood pressure at the clinical setting, the pressure was also measured by the doctor using conventional mercury sphygmomanometer. Three measurements were recorded at each place but only one each day. Results: Good correlation was found between mercury sphygmomanometer and automatic meter measured at the clinic when measured by standard correlation coefficients (r=0.9; p<0.001). Agreement analysis demonstrates however, more discrepancy between these two methods. Mean blood pressure is similar at the clinic and at work, but significantly higher than mean blood pressure at home (p<0.001 for both systolic blood pressure and diastolic blood pressure). Possible white coat (15%) and work ...
