Examination of Several Physiological and Psychosocial Factors Potentially Associated with Masked Hypertension Among Low-Risk Adults

摘要

We examined the association of factors in addition to prehypertensive office blood pressure (BP) level that might improve detection of masked hypertension (MH, defined as non-elevated office BP with elevated out-of-office BP average) among those otherwise at low-risk. This sample of 340 untreated adults 30 years and older with office BP average <140/90 mmHg all had two sets of paired office BP measurements and 24-hour ambulatory BP monitoring (ABPM) sessions one week apart. Other than BP levels, the only factors that were associated (at P<0.10) with MH at both sets were male sex (75% vs 66%) and working outside the home (72% vs 59% first set; 71% vs 45% second set). Adding these variables to BP level in the model did not appreciably improve detection of MH. We found no demographic, clinical, or psychosocial measures that improved upon prehypertension as a potential predictor of MH in this sample.
