Telomere reprogramming during fetal life in low socioeconomic mothers

Background Relative telomere length (RTL), the biological chronometer, varies considerably among individuals under the influence of multiple risk factors such as socioeconomic status (SES). It is anticipated that during fetal life, telomeres undergo reprogramming. The purpose of this study is to find the association between SES and telomere length of mother-newborn and genetic remodeling that occurs during fetal life. Results The mean telomere/single gene copy (T/S) ratio and RTL (base pairs) among 250 mother-newborn dyads were higher in cord blood of newborns (1.18 ± 0.23) (6765 ± 1350 bp) (95% confidence level) compared to maternal blood (1.13 ± 0.18) (6432 ± 1350 bp) of all SES of the Pakistani population. A positive association ( r = 0.396, p
