The MCH Life Course Toolbox provides online resources for various MCH professionals from research, academia, practice, and policy; it also provides a venue for anyone interested in the Life Course Perspective to share information and strategies on how to engage this framework at the local, state, and national levels. The Life Course Perspective builds upon the socio-ecological model and considers the "complex interplay of biological, behavioral, psychological, social, and environmental factors contribute to health outcomes across the course of a person's life" to promote health and prevent disease. Visit the MCH Life Course Toolbox to learn more and engage your local health department in the Life Course Perspective, and strategize with your MCH colleagues on how to work across health and non-health sectors to promote healthy lives for women, children, and families at all stages of life.
