Abstract
Background The aim of the study was to estimate the relationship
between anthropometric indices, blood pressure
and peripheral blood flow in subjectively healthy subjects.
Material and methods The study group consisted of 72 healthy men, aged 41 years (16-58), BMI 25.8 kg/m2 (16.9-34.6). Body composition was analyzed using bioelectrical impedance method. The value of fat free mass (FFM) were 66.6 kg (48.2-88.1), which means 80% (68.6-96.3). Fat mass (FM) was 16.5 kg (3-32.8) which means 20% (5.5-31.4). Mean values of systolic (SBP) and diastolic (DBP) blood pressure measurements for 24-hour period (SBP24, DBP24), as well as for daytime and nighttime periods were conducted using Spacelabs 90207 devices. SBP24 and DBP24 were 119 mm Hg (95-151) and 73 (55-97) mm Hg, respectively. Peripheral blood flow was assessed using forearm strain-gauge plethysmography and described by following indices: arterial inflow (AI), forearm blood flow (FBF), venous capacitance (VC), partial venous outflow 0.5-2 s (VO0.5-2.0), venous outflow (VO).
Results Arterial inflow was mainly determined by SBP24 and by both FFM and body mass. Partial venous outflow was determined by SBP24 and BMI. Fast blood flow was determined by SBP24 only.
Conclusions The parameters describing body mass (total body mass, BMI) and SBP24 are important determinants of V0,5-2,0 and arterial inflow. Our results suggest that arterial blood pressure should be taken into consideration when relationship between antropomethric indices and parameters of peripheral blood flow is examined.
