Key result
Standing significantly increased ambulatory blood pressure in type 1 diabetics with disease duration <5 years (ΔSBP 4±5 mmHg, P<0.01), but not in those with duration ≥10 years or microangiopathy.

Position may influence ABPM readings in early T1D; leaves open whether duration-specific norms are needed.

Does position change affect 24-h ambulatory blood pressure in patients with type 1 diabetes?

In patients with type 1 diabetes, the normal increase in blood pressure upon standing is lost with longer disease duration and the presence of microangiopathy.
Benhamou et al. (2001) conducted a cross-sectional in Type 1 diabetes (n=44). Standing position vs. Supine/sitting position was evaluated on Ambulatory systolic and diastolic blood pressure (DeltaSBP 4 mmHg, p=< 0.01). Standing significantly increased ambulatory blood pressure in type 1 diabetics with disease duration <5 years (ΔSBP 4±5 mmHg, P<0.01), but not in those with duration ≥10 years or microangiopathy.
