Awareness of blood pressure: interoception or contextual judgement?

Most patients with mild to moderate hypertension are asymptomatic but some patients report symptoms and seem to be aware of their blood pressure. The research question is whether the estimation of blood pressure is primarily derived from interoception or is inferred by contextual judgement. A psychophysiological ambulatory assessment was conducted with 51 male hypertensive patients and 30 either normotensive or hypotensive student subjects employing (1) a multichannel recording system for blood pressure, heart rate and physical activity; and (2) a pocket computer for assessing estimated BP, setting variables and self-ratings of subjective state. Within-subject correlations revealed that there was no significant relationship between estimated BP and concurrently recorded systolic BP. Estimated BP is, however, related to self-ratings of feeling physically tense and self-ratings of physical activity. Blood pressure awareness appears to be a rather inconsistent and subjective phenomenon, based on contextual judgements and inferences instead of "perception", but it is a relevant methodological issue (and possible bias) in hypertension research.
