Abstract/OtherAbstract:
INTRODUCTION: Epidemiological studies suggest skeletal growth is programmed during intrauterine and early postnatal life. We have investigated this in a rat model of maternal protein insufficiency.
METHODS: Dams received either 18% w/w (control) or 9% w/w (low protein) diet during pregnancy, and the offspring were studied at selected time points (4, 8, 12, 16, 20, 47 weeks).
RESULTS: Alkaline phosphatase activity in controls reached peak levels from 8 to 20 weeks of age. In contrast, restricted diet offspring were at peak levels from 4 weeks of age. Peak levels were similar in both groups. Serum IGF-1 levels were lower in female restricted diet offspring at 4 weeks of age, and serum osteocalcin was significantly higher at 4 weeks of age in male and female offspring from mothers fed the restricted diet, whereas serum 25-OH vitamin D was significantly lower in restricted diet males at 8, 12, and 20 weeks of age.
CONCLUSIONS: These data indicate that a low protein diet in utero affected the osteogenic environment in the offspring with effects that persist into late adulthood. These results indicate the key role of the nutritional environment in early development on programming of skeletal development with implicit consequences in later life.
