Abstract

Recent evidence links low birthweight and poor adult bone health. We characterised bone size, mineral content, density and strength (stress strain index of bone bending strength (SSI)) in rats from weaning to 12 months. Bilateral uterine vessel ligation (Restricted) or sham surgery (Control) was performed on gestational Day 18 in rats inducing uteroplacental insufficiency. Postmortem of male and female offspring was performed at postnatal Day 35 and at 2, 4, 6 and 12 months. Femur mineral content, density and strength were measured using quantitative computed tomography (pQCT). Restricted pups were born 10%-15% lighter and remained smaller with shorter femurs than Controls (P<0.05). Male and..
