Takeaway

  • Hypertension prevalence at third visit was lower than high BP prevalence (HBP) at first and second visit.

Why this matters

  • In adolescents reported HBP ranges from 0.46% to 12%, probably a result of different methods employed for identification.
  • Results reinforce previous observation of reduced HBP with increasing number of visits/measurements, probably because of reduced anxiety.

Study design

  • This cross-sectional study evaluated 481 adolescents aged 14-19 y between June and November 2014.
  • BP measured at first visit and repeated in case of HBP.
  • BP calculations categorized as: BP at first visit (measurement 1), mean of first and second visit (measurement 2), mean of first, second and third visit (measuremen...
