This comprehensive work explores maternal and child health through a life-course perspective, emphasizing the interconnectedness of health stages rather than viewing them in isolation. It discusses early programming, racial and ethnic disparities in birth outcomes, prenatal stress, and the impact of maternal diabetes on childhood obesity. By integrating insights from epidemiology, public health, and maternal care, the study advocates for innovative strategies that address the underlying conditions affecting health across generations, ultimately aiming to improve outcomes for children and families.

  33. Rethinking Preterm Birth Vulnerability to preterm delivery may be traced to not only exposure to stress & infection during pregnancy, but host response to stress & infection (e.g. stress reactivity & inflammatory dysregulation) patterned over the life course (early programming & cumulative allostatic load)

  43. How Can This Be?

  44. How Can This Be? First, the pathways to better health do not generally depend on better health care, and second, even in those instances in which health care is important, too many Americans do not receive it, receive it too late, or receive poor-quality care. Schroeder SA. NEJM 2007;357:1221-8

  45. How Can We Do Better? Transform maternal and child healthcare Assure the conditions in which all mothers and children can be healthy
