Abstract
Despite the lifecourse focus of nursing clinical care, nursing research largely remains cross-sectional or process-oriented within silos determined by patient characteristics such as age, acuity, or disease process. Incorporating interdisciplinary lifecourse theory into pediatric nursing research provides the opportunity to expand nursing theories and research beyond practice, age, and disease silos. One such theory is the Lifecourse Health Development (LCHD) framework. LCHD takes a more expansive view of health development from preconception through old age based on the premise that health is a consequence of transactions between genetic, biological, behavioral, social, and economic contexts that change as a child develops over time (Halfon & Hochstein, 2002). LCHD also explains how intergenerational influences and prevention during early life help predict health development and disease over the lifespan. The preventive and lifecourse focus of LCHD is well-aligned with the lifespan wellness foci of pediatric nurses. The purpose of this article is to introduce pediatric nurse researchers to LCHD and discuss proposed augmentations and implications related to expanding LCHD into pediatric nursing research.
