row percentages.
*For those with an index BP ≥95th percentile, up to 3 consecutive measurements were used to assign final BP status. Hypertension was defined by 3 consecutive BP ≥95th percentile (or SBP ≥140 mmHg and/or DBP ≥90 mmHg for subsequent BP at age ≥18 years of age). Within this subgroup, there were 1900 (67.9%) children and adolescents with repeat BP <95th percentile and 730 (26.1%) with no subsequent BP available for final assignment.
†Odds ratio (OR) and 95% confidence intervals (CI), adjusted for differences in age, sex and race/ethnicity.
