Body weight and fat cell size in young men with mild blood pressure elevation.
The aim of the study was to assess the relationship between body fat distribution and blood pressure. Forty-four men, aged 19-22 years, with mild blood pressure elevation (MBPE) and 29 normotensive controls (NC) were investigated. Body fat distribution was assessed by calculating fat cell size in biopsy samples of adipose tissue from different subcutaneous depots. The subjects in MBPE group were heavier than those in NC group (79.7 +/- 2.7 and 71.5 +/- 1.6 kg, p < 0.05). Total body fat was also significantly higher in the MBPE group (12.5 +/- 1.6 and 8.1 +/- 1.3 kg, p < 0.05) but not the lean body cell mass (36.8 +/- 1.1 and 34.7 +/- 0.9 kg, n.s.). Fat cell size (microgram/cell) in the lower abdominal area were significantly bigger in MBPE than in NC (respectively 40.9 +/- 4.4 and 28.0 +/- 3.1, p < 0.05). The same differences applied for fat cell size in the upper abdominal (respectively 43.1 +/- 3.0 and 26.8 +/- 3.0, p < 0.001) and averaged abdominal areas (respectively 40.1 +/- 3.4 and 26.8 +/- 2.8; p < 0.05). Fat cell size in gluteal, femoral and averaged gluteofemoral areas did not differ between MBPE and NC. Therefore, the abdominal/gluteofemoral ratio was significantly higher in MBPE than in NC (respectively 1.1 +/- 0.1 and 0.7 +/- 0.1; p < 0.005).(ABSTRACT TRUNCATED AT 250 WORDS)
