“…The definition of national blood pressure references for children and young adults, aged 4-23 years, living in Great Britain provides important, complementary information to the updated US guidelines on the management of high blood pressure in children and adolescents aged 1-17 years, 2 as well as to earlier attempts to define normative blood pressure values from other countries. [3][4][5][6][7] In addition, these centiles will integrate existing charts in the UK regarding other important parameters (eg, body mass index), thereby allowing a more comprehensive characterisation of the health of children. Some distinctive aspects of the study by Jackson et al 1 should be highlighted: the representative and large sample size of the seven surveys from which blood pressure data were drawn; the consistent method applied for blood pressure measurements; the use of a statistical technique such as the LMS method to construct blood pressure centiles, which accounts for the skewness (L), median (M), and coefficient of variation (S) of the blood pressure distribution.…”
