Weight, body composition and fat distribution of Czech women in relation with reproductive phase: a cross-sectional...

A sample of 213 healthy Czech women was classified into four groups according to their reproductive phase: fully reproductive, premenopausal, menopausal and postmenopausal women. Changes in body weight, body composition and fat distribution were studied in those four groups using the classical anthropometric method. Body weight rises till the menopause with no further increase. A decrease in relative contribution of muscle and bone mass was observed. The progressive increase in fat mass with age was clearly demonstrated, both the fat mass weight (r = 0.38, p < 0.001) and its percentage contribution (Matiegka r = 0.40, p < 0.001, Parízkovi r = 0.42, p < 0.001). There is a stronger correlation of central fat indices as WHR (r = 0.57, p < 0.001), abdominal (r=0.56, p < 0.001) and waist circumference (r = 0.50, p < 0.001) than for hip circumference (r = 0.27, p < 0.001) to the age. WHR and waist increase most when fully reproductive and premenopausal women were compared (p < 0.001); less when premenopausal to menopausal women are compared (NS) and the least when menopausal to postmenopausal women were compared (NS). The mean values of 14 skinfolds thickness are shown, the skinfold at the abdomen shows the strongest correlation to the age (r = 0.49, p < 0.001). The results are consistent with the hypothesis of progressive fat centralisation.
