Abstract
ABSTRACT Objective: Loss of bone mineral density follows as a consequence of hormonal changes, as women transit from perimenopause to menopause. This study investigated the effect of such a transition on bone demineralisation among Black South African women.Methods: Two groups of women stratified by their menstrual history into perimenopause (n = 28) and postmenopause (n = 32), were enrolled for the study. Each of the study participants had her Body Mass Index (BMI) determined and a sample of blood was taken and analysed for follicle stimulating hormone (FSH). Bone mineral density was assessed for the hip bone using the Dual-Energy X-ray Absorptiometry machine (DEXA; Hologic 4500). Results: The mean age (± SD) of perimenopausal women was 44.6 years (± 3.6) compared with 63.4 years (± 7.2) for postmenopausal women. There was no statistical significant difference in the BMI of women in the two groups (p = 0.4671) and the serum FSH concentration of 46 to 100 mIu/mL (mean = 78 mIu/Ml; ± 0.69) confirmed the status of postmenopause. The negative slope of the change in hip BMD amongst perimenopausal women (-0.0006) translates to BMD loss of 0.06% per annum. This compares with hip BMD loss of -0.0025 (i.e. BMD loss of 0.25%/annum) amongst the postmenopausal women. This represents a 4-fold loss of BMD in postmenopausal compared with perimenopausal women.Conclusions: This study provides evidence that black South African women would begin to experience loss of bone mineral density of the hip in their transition from perimenopause to postmenopausal state.
