AimWe aimed to describe the age-related changes of the body composition and adipose tissue distribution in Bulgarians. Material and methodsThis cross-sectional study included 130 participants (mean age 53±9.8 years, range 35–65), divided according to their body mass index (BMI): BMI<25.0kg/m2 (18 women, 12 men); BMI 25.0–34.9kg/m2 (50 women, 50 men). Body composition was assessed by bioelectrical impedance on a Tanita TBF-215 analyzer (Tanita Corp., Tokyo, Japan). The abdominal fat was measured by computed tomography on a CT/L scanner (GE Medical Systems, USA). ResultsIncreasing age was associated with a mean decrease in body weight by 268g per year in the normal weight subjects and by 390g in the overweight ones as well as with a fat-free mass decrease of 321g and of 291g per year respectively (p<0.001). One year of increasing age was associated with a mean increase of visceral adipose tissue by 2.43cm2 in the overweight group and by 2.68cm2 in the normal weight subjects and with a decrease of the subcutaneous adipose tissue by 2.30cm2 per year in the latter group (p<0.001). The association of fat mass and fat-free mass with age in men and women was best described by quadratic equations (both increased until the age of 45–50 and decreased thereafter). ConclusionsOur data showed a significant association between age and decreasing fat-free mass, increasing fat mass and abdominal fat accumulation. ER -
