title: [Two compartment model of body composition and abdominal fat area in postmenopausal women - pilot study].
abstract: BACKGROUND
  Both menopausal period and aging have influence on body composition, increase of total body fat and visceral fat in particular. We should be aware that changes in body composition, mainly fat translocation to abdominal region, can occur without significant changes in body weight. Therefore quantitative abdominal fat assessment should be our aim.
  
  
  OBJECTIVE
  Body composition analysis based on two compartment model and abdominal fat area assessment in cross section.
  
  
  METHODS
  Subjects in postmenopausal period (41 women) were recruited for this study and divided into 2 groups: group 1 - women aged 45-56 years and group 2 - women aged 57-79 years. Body composition analysis and abdominal fat area assessment were conducted by using bioelectrical impedance method with BioScan 920 (Maltron int.) accordingly with standardized procedure.
  
  
  RESULTS
  Women in early postmenopausal stage (Group 1) had statistically significant lower total body fat percentage in comparison with women in late postmenopausal period (Group 2) (41.09 ± 7.72% vs. 50.7 ± 9.88%, p=0.0021). Also women in group 1 were characterized by significant lower visceral fat area (VAT) as well as subcutaneous fat area (SAT) in comparison with group 2 (respectively VAT 119.25 ± 30.09 cm2 vs. 199.36 ± 87.38 cm2, p=0.0011; SAT 175.19 ±57.67 cm2 vs. 223.4±74.29 cm2, p=0.0336). According to VAT criteria (>120 cm2), 44% of women in group 1 and 80% in group 2 had excess of visceral fat.
  
  
  CONCLUSIONS
  Both total body fat and intra-abdominal fat increased with age, independently of weight changes.
