Looking Back, Visioning Forward: Preconception Health in the US 2005 to 2023.

Preconception health has always been about preventative health care, ensuring the overall wellbeing of people of reproductive age before they have children. However, just as public health and health care have shifted to prioritize equity and include ideas about how social determinants of health influence health outcomes, the field of preconception health has experienced a similar transition. The purpose of this paper is to provide an overview of the evolution of preconception health in the United States after 2005, highlighting the key tensions that have shaped the field. We provide an overview of the early history of the movement and describe how four phases of ideological tensions overtime have led to changes across seven categories of preconception health: definitions and frameworks, surveillance and measurement, messaging and education, strategic convenings and collaborations, clinical practice, and reproductive life planning. We also describe the historic and emerging challenges that affect preconception care, including limited sustained investment and ongoing threats to reproductive health. The vision of preconception health care we outline has been created by a diversity of voices calling for wellness, equity, and reproductive justice to be the foundation to all preconception health work. This requires a focus on preconception health education that prioritizes bodily autonomy, not just pregnancy intentions; national surveillance and data measures that center equity; attention to mental health and overall well-being; and the inclusion of transgender and non-binary people of reproductive age.
