Abstract

The frequency of X chromosome loss in women increases with ageing. Numerous cases have linked the numerical reduction of sex chromosomes to the development of malignant tumours, recurrent miscarriages and Alzheimer’s disease. The main aim of the study was to investigate the age pattern and secular trend of the cytological ageing (X chromosome loss), as well as to analyse the relationship between the level of chromosome loss and body and bone structural parameters in adult women. Twenty-one women aged between 20–40 years were enrolled to the present study. Body mass components were estimated by body impedance analysis, bone structure was estimated by quantitative ultrasound technique. Cellular ageing was assessed by X chromosome loss estimation (using FISH probe). The results revealed an increased level of X chromosome loss in women aged between 21–30 compared to their age-peers lived decades before, and women aged between 31–40 and studied in 2021. By considering the body and bone structural profile (another indicator of their biological status) of women in the younger age-group, an increased fat component and a decreased skeletomuscular component could be described in this age-group. The results are rather preliminary, that aimed to explore explanatory components in the changes in the rate of X chromosome loss. In order to establish the findings, further investigations, as well as the increase of the sample size is required.
