Body composition estimated by bioimpedance analysis in Sicilian climacteric women

Minerva Ginecol. 2008 Aug;60(4):311-6.

Abstract

Aim: The aim of this study was to evaluate the effects of menopause transition on body weight, and body composition in a Sicilian climacteric population.

Methods: Two hundred and nine (60 pre- and one 149 postmenopausal) untreated, healthy women were selected. Body composition was estimated by BIA101 of AKERN SRL. Body Mass Index (BMI), waist and hip circumferences were also measured.

Results: The mean BMI of the study population was 29.4+/-0.7. There was no significative difference between pre- and postmenopausal subjects regarding BMI (chi-squared=9.25; P=0.16), its class distribution, fat mass (FM), TBW and waist-to-hip ratio (WHR). The FM was significantly more represented in pre- than in postmenopausal women (47.43+/-1.33 vs 45.02+/-0.81 kg) (P<0.01). Linear regression analysis showed a positive correlation between BMI and fat free mass (FM) percentage (chi-squares=0.7045) nevertheless among the subjects aged=or>55 years, in 57% of the normo-weight the body fat (BF) percentage was undesirably high.

Conclusion: Climacteric changes and aging process are related to changes in body weight and fat distribution; even subjects apparently ''normo-weight'' (BMI below 25) were ''over-fat'', because revealed undesirably high BF%. Further investigation in larger population is needed to define whether BMI or BF% better predicts the risk of obesity-related diseases in climacteric Sicilian women.
