Severe obesity in children: prevalence, persistence and relation to hypertension

Table 3 Blood pressure in obese children and adolescents classified based on percentage of the 95 ^th percentile for body mass index (BMI)

BMI > 95^thpercentile	Normal blood pressure (BP)	Prehypertension	BP ≥95^thpercentile^*	Confirmed hypertension	Adjusted odds of hypertension
BMI > 95^thpercentile	N = 12802	N = 5308	N = 2796	N = 166	OR (95% CI)^†
100-109% × 95^th percentile	5976 (67.2%)	2012 (22.6%)	903 (10.2%)	40 (0.5%)	-

row percentages.
^*For those with an index BP ≥95^th percentile, up to 3 consecutive measurements were used to assign final BP status. Hypertension was defined by 3 consecutive BP ≥95^th 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 <95^th 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.
