From the article:
Human studies in siblings show that children born to a mother who was obese during pregnancy are at greater risk of heart disease than siblings born to the same mother after bariatric surgery to reduce maternal obesity. Such studies have provided strong evidence in humans that the environment experienced during critical periods of development can directly influence long-term cardiovascular health and heart disease risk.
[New research] shows that adult offspring from pregnancies complicated by chronic hypoxia have increased indicators of cardiovascular disease, such as high blood pressure and stiffer blood vessels.
The Cambridge study, led by Professor Dino Giussani, used pregnant sheep to show that maternal treatment with the antioxidant vitamin C during a complicated pregnancy could protect the adult offspring from developing hypertension and heart disease. The work therefore not only provides evidence that a prenatal influence on later heart disease in the offspring is indeed possible, but also shows the potential to protect against it by “bringing preventative medicine back into the womb,” as Dr Kirsty Brain, first author of the study, puts it.
