Brief description The Metabolic Syndrome is a shorthand term for a collection of disorders in the same individual; including Diabetes, high cholesterol levels, hypertension, atherosclerosis and obesity. These conditions have previously been assumed to occur because of genetic influences, acting in combination with the individual's lifestyle. However, another factor may also be important in causing the metabolic syndrome. A recent theory suggests that adverse events occurring during fetal development may result in low birth weight and lead to metabolic changes which cause the metabolic syndrome in adulthood. This theory, if true, would have profound implications for the prevention of these common problems; which are the leading cause of death in developed countries. The validity of the Fetal Origins Hypothesis is curently uncertain. Confounding genetic and environmental factors make it difficult to separate the role of genetic, fetal and environmental influences. Studies of twins have the potential to sort out this important question. We will study the association between birthweight and the metabolic syndrome in sets of identical twins who have identical genes and similar environmental backgrounds. We will use a set of metabolic and hormone tests to define the characteristics of each twin. We will also employ a novel non-invasive method of measuring cell metabolism using magnetic resonance spectroscopy. If we find that the twin with lower birthweight usually has more adverse features of the metabolic syndrome, this will point to an important cause of cardiovascular disease. This study will provide very important insights into the influence of early life on subsequent health and may lead to a dramatic changes in our approach to the prevention of common diseases. Improving the health and well-being of pregnant mothers and their babies may turn out to be one of the most important public health issues that we can address.
