Mean (±SD) a systolic and b diastolic blood pressure measurements across a 4-year period for boys and girls. Both systolic (SBP) and diastolic blood pressure (DBP) increased during the 4-year observational period in boys and girls. In boys, SBP increased from 114.5 ± 8.5 mm mercury (mmHg) at Grade 7 to 123.3 ± 7.9 mmHg at Grade 11 and DBP from 66.1 ± 6.4 mmHg at Grade 7 to 69.9 ± 5.4 mmHg at Grade 11. In girls, SBP increased from 114.6 ± 9.4 mmHg at Grade 7 to 122.3 ± 7.6 mmHg at Grade 11 and DBP from 67.4 ± 6.4 mmHg at Grade 7 to 70.0 ± 5.0 mmHg at Grade 11.
