Engaging Families in Life Course Intervention Research: An Essential Step in Advancing Equity

What Makes an Intervention a Life Course Intervention?

OBJECTIVES

To develop an initial list of characteristics of life course interventions to inform the emerging discipline of life course intervention research.

METHODS

The Life Course Intervention Research Network, a collaborative national network of >75 researchers, service providers, community representatives, and thought leaders, considered the principles, characteristics, and utility of life course interventions. After an in-person launch meeting in 2019, the steering committee collaboratively and iteratively developed a list of life course intervention characteristics, incorporating a modified Delphi review process.

RESULTS

The Life Course Intervention Research Network identified 12 characteristics of life course interventions. These interventions (1) are aimed at optimizing health trajectories; (2) are developmentally focused, (3) longitudinally focused, and (4) strategically timed; and are (5) designed to address multiple levels of the ecosystem where children are born, live, learn, and grow and (6) vertically, horizontally, and longitudinally integrated to produce a seamless, forward-leaning, health optimizing system. Interventions are designed to (7) support emerging health development capabilities; are (8) collaboratively codesigned by transdisciplinary research teams, including stakeholders; and incorporate (9) family-centered, (10) strengths-based, and (11) antiracist approaches with (12) a focus on health equity.

CONCLUSIONS

The intention for this list of characteristics of life course interventions is to provide a starting point for wider discussion and to guide research development. Incorporation of these characteristics into intervention designs may improve emerging health trajectories and move critical developmental processes and pathways back on track, even optimizing them to prevent or reduce adverse outcomes.

Building a Life Course Intervention Research Framework

OBJECTIVES

To report on first steps toward building a Life Course Intervention Research Framework (LCIRF) to guide researchers studying interventions to improve lifelong health.

METHODS

The Life Course Intervention Research Network, a collaborative national network of >75 researchers, service providers, community representatives and thought leaders, participated in an iterative review process. Building on the revised Medical Research Council Guidance for Developing and Evaluating Complex Interventions, they identified 12 additional key models with features for inclusion in the LCIRF, then incorporated the 12 characteristics identified by the Life Course Intervention Research Network as actionable features of Life Course Interventions to produce the new LCIRF.

RESULTS

The LCIRF sets out a detailed step-wise approach to intervention development: (1) conceptualization and planning, (2) design, (3) implementation, (4) evaluation, and (5) spreading and scaling of interventions. Each step is infused with life course intervention characteristics including a focus on (1) collaborative codesign (2) health optimization, (3) supporting emerging health development capabilities (4) strategic timing, (5) multilevel approaches, and (6) health equity. Key features include a detailed transdisciplinary knowledge synthesis to inform intervention development; formation of strong partnerships with family, community, and youth representatives in intervention codesign; a means of testing the impact of each intervention on biobehavioral processes underlying emerging health trajectories; and close attention to intervention context.

CONCLUSIONS

This first iteration of the LCIRF has been largely expert driven. Next steps will involve widespread partner engagement in framework refinement and further development. Implementation will require changes to the way intervention studies are organized and funded.

The Emergence of Life Course Intervention Research: Optimizing Health Development and Child Well-Being

Advances in life course health science, systems biology, and epigenetics suggest that health development can be represented as a trajectory affected by multiple risk and protective factors arrayed in a relational developmental ecosystem across child, family, community, and systems levels. Despite tremendous potential for early life interventions at multiple levels of this ecosystem to improve children's life course health trajectories, this potential has not been fully explored. In fact, Life Course Health Development is a low priority for both health care and research funding. Representing the work of the Life Course Intervention Research Network, this supplement to Pediatrics reports on the first steps taken to define the emerging discipline of life course intervention research. Articles cover the characteristics of life course interventions together with a research framework and core competencies for this work. Topics include family, community, and youth engagement as vital components of grounding this work in health equity, family health development and its measurement, supporting children after prematurity, and new approaches to early childhood mental health. Schools and telehealth are considered innovative platforms for life course interventions, whereas cross-sector partnerships are recognized as key components of interventions to address childhood adversity. Researchers apply a Life Course Health Development lens to juvenile justice issues, including the minimum age law, and consider potential trade-offs whereby "striving" (education and income mobility) can limit "thriving" (health mobility) for people of color and those raised in low-income families. Finally, we present the Australian experience of embedding life course interventions in longitudinal studies.
