Final answer:
The Developmental Origins of Health and Disease (DOHaD) concept and approach both focus on the influences of early life experiences on future health, but differ in their emphasis. The approach focuses more on prenatal influences, while the concept additionally considers effects of experiences in postnatal life and adulthood.
Step-by-step explanation:
The Developmental Origins of Health and Disease (DOHaD) concept posits that environmental factors, particularly nutrition, during early development have long-term effects on health and disease outcomes. This approach focusses on the prenatal and early postnatal period as crucial windows of developmental plasticity. Similarities between the DOHaD approach and concept include an emphasis on early life experiences and their lasting impact on health. Furthermore, both posit that interventions to optimize early development can have significant public health benefits.
However, there are also differences. The DOHaD approach generally puts more emphasis on prenatal influences while the broader concept of DOHaD also encompasses postnatal life and even adulthood. The concept of DOHaD also includes the idea that these early influences can be modified or 'programmed' by later life experiences, an aspect less emphasized in the initial DOHaD approach.
