Are the WHO criteria for hypertension appropriate in young insulin-dependent diabetics?

Normal adult blood pressure is arbitrarily defined as a systolic pressure equal to or below 140 mmHg together with a diastolic (5th phase) equal to or below 90 mmHg. Hypertension in adults is arbitrarily defined as a systolic pressure equal to or greater than 160 mmHg and/or diastolic (5th phase) equal to or greater than 95 mmHg. The term 'borderline hypertension' is used to denote blood pressure values between the normal and the hypertensive ranges as described above. The blood pressure levels at which hypertension can be defined for children vary with age, but precise levels are under review. Clearly values that would be regarded as hypertensive are lower in children than in adults.
