Effects of sleep restriction during pregnancy on lipids and glucose homeostasis of female offspring submitted to ovariectomy.
JOURNAL OF DEVELOPMENTAL ORIGINS OF HEALTH AND DISEASE(2019)
摘要
Sleep shortening during pregnancy may alter the mother's environment, affecting the offspring. Thus, the present study evaluated the metabolic profile of female offspring from sleep-restricted rats during the last week of pregnancy. Pregnant Wistar rats were distributed into two groups: control (C) and sleep restriction (SR). The SR was performed 20 h/day, from 14th to 20th day of pregnancy. At 2 months, half of the offspring were subjected to ovariectomy (OVX); the others, to sham surgery. Studied groups were Csham, Covx, SRsham and SRovx. Cholesterol (HDL, LDL and C-total), triglycerides (TG) and glucose and insulin tolerance tests (GTT-ITT) were evaluated at 8 months. RSsham presented higher values of TG, while SRovx presented higher TG, LDL and C-total. Basal glucose concentration was increased in SRsham and SRovx. These data suggest that SR during pregnancy may be a risk factor for the development of diseases in adult female offspring.
