OBJECTIVE: The aim of this study was to determine the long-term effects of chronic placental insufficiency on the metabolic state and organ structure in the fetal and adolescent guinea pig. STUDY DESIGN: The maternal uterine artery was ligated at day 28-30 to reduce placental function and restrict fetal growth. Whole body and tissue weights and plasma metabolites were determined at 60 days of gestation and 8 weeks of age; tissue structure was determined at the latter age in restricted and control offspring. RESULTS: Fetal growth restriction increased fibrosis in the heart and kidneys (P < .05), increased aortic wall thickening (P < .01), reduced the number of glomeruli in the kidneys (P < .05), and increased the plasma urea and chloride in adolescent offspring. CONCLUSION: This study demonstrates that diseases in the heart, aorta, and kidneys that result from an adverse prenatal environment are evident at adolescence and may contribute to subsequent adult disease.
