Relative risk of hypertension by BMI category (adjusted for gender and family history).

Blood pressure	Relative risk*	Confidence interval
In overweight children:
Systolic pre-hypertension	1.44	0.15–13.34
Diastolic pre-hypertension	0.94	0.11–8.03
Systolic hypertension	2.23	0.22–22.86
Diastolic hypertension	1.24	0.14–11.23
In obese children:
Systolic pre-hypertension	5.65	0.92–34.85
Diastolic pre-hypertension	1.39	0.15–13.13
Systolic hypertension	14.69	2.45–88.2
Diastolic hypertension	3.61	0.58–22.52
