A framework that organizes research from various fields into a theoretical approach to explain how individual and population health develops is referred to as life course health development (LCHD). It is also useful in understanding how the dynamic course of their health and illness is determined by the interactions between environmental and biological factors during the lifetime. It provides a base to interpret how people's experiences in the early stages of life affect later functional status and health conditions. LCHD supports health care purchasing strategies for improving health outcomes by suggesting new strategies for research, health measurement and service delivery to develop health throughout life and human health capital. This book unravels the recent studies in the field of life course health development. It is an upcoming field of science that has undergone rapid development over the past few decades. Scientists and students actively engaged in this field will find this book full of crucial and unexplored concepts.
