Background: This study was designed to investigate whether there was ally difference in blood pressure (BP) readings between sitting and supine positions in diabetic and non-diabetic subjects.
Material/Methods: BP in sitting and supine position was measured in 356 patients with type 2 diabetes (study group) and in 356 age- and sex-matched non-diabetic subjects (control group).
Results: The systolic and diastolic BP in the supine position was significantly higher than in the sitting position in both groups (P<0.001). The BP increment in the supine position was similar in the study and control groups (P>0.05). Multivariate logistic regression analysis of the study group showed that age was all independent predictor for the Systolic pressure increment (P=0.001), whereas body mass index was all independent predictor for the increment in diastolic BP (P=0.04). The levels of sitting BP were inversely correlated with the pressure increments in the supine position in the diabetic patients (P<0.001). In diabetic and non-diabetic subjects, BP in a supine position is higher than in the sitting position.
Conclusions: In diabetic patients, age, body mass index and the levels Of Sitting BP seem to have significant, impact Oil the pressure increment, from a sitting to the supine position.
