Origins

The field of epigenetics is revolutionizing our understanding of how environment shapes our genes. Dr. Susan Prescott is a leading childhood immunologist who shows how the application of epigenetics through Developmental Origins of Health and Disease (DOHaD) is changing scientific research and public health. A poor start to life is associated with an increased risk of disorders throughout life, including cardiovascular disease, obesity, type 2 diabetes and metabolic disturbances, osteoporosis, chronic obstructive lung disease, some forms of cancer, and some mental illnesses. The environment in which early life develops - at conception, and/or during fetal life, infancy, and early childhood - induces changes in development that have a long term impact on later health and disease risk. Parental lifestyle, diet, smoking, obesity, as well as exposure to endocrine disruptor chemicals and toxins, have all been shown to modulate disease risk. The effects of such exposures are often graded and subtle - they do not simply disrupt development or induce disease themselves - but can affect how rapidly disease develops in an individual. However, timely interventions may reduce such risk in individuals and also limit its transmission to the next generation. DOHaD has significant implications for many societies and for global health policy. Therefore, in this book, Dr. Prescott explains the research and shows how a focus on early life - in health promotion, the exchange of knowledge between policymakers, clinical and basic scientists and the wider public, and education and training - will build capacity to assist a healthy start to life across populations.
