METHODS: BP was measured among 20 716 adults from a general population. SBP was classified using the first reading (normal SBP or hypertension) and compared with the average SBP using different guideline protocols (reclassification).
RESULTS: Reclassification from normal SBP to hypertension was greatest with Canadian Hypertension Education Program guidelines (3% younger, 12% older individuals) and reclassification from hypertension to normal SBP was greatest with National Institute for Health and Care Excellence guidelines (70% younger, 44% older individuals). SBP increased between the first two measures in 37%, decreased in 56% and did not change in 7% of the population. Age had a strong interaction with SBP level (P < 0.0001) so that younger individuals exhibited greater SBP differences over repeated measures.
CONCLUSION: This study highlights the need for an improvement in the evidence-base regarding the best way to assess office BP for correct hypertension diagnosis.
