INFANT HEALTH- Promoting Mental Health and Healthy Weight in Infancy Through Sensitive Parenting

Plain-language summary

Mental health problems and overweight often co-occur, they have their origin in early childhood and new research evidence suggest a key role of cognitive, emotional and behavioral regulation in the early developmental trajectories and points to the benefits of intervention in infancy that builds on strategies of sensitive parenting. The research group behind this project has developed the PUF program (PUF: In Danish: 'Psykisk Udvikling og Funktion') to target infants' mental health and development within the settings of community health nurses. Still, measures are lacking that address the infants most vulnerable regarding the development and progression of mental health problems and overweight. In this project, we develop and test a new intensified intervention to address major cognitive and regulatory vulnerabilities identified at child age 9-10 months and adapted to the settings of community health nurses. The intervention is created as an add-on to the PUF-program, using an evidence-based method to promote sensitive parenting, the Video-based Intervention to Promote Positive Parenting (VIPP). The new intervention VIPP-PUF comprises six therapeutic sessions delivered by the community health nurse during home visits over a three months period. The intervention builds on teaching the health nurses to promote parents' sensitivity to meet the infants' cognitive and regulatory vulnerabilities, and it takes in account the needs of psycho-socially disadvantaged families. The Infant Health project is conducted in sixteen municipalities across Denmark. We use the Intervention Mapping approach as the study frame and integrate the best practice of community health nurses. The efficacy of the VIPP-PUF intervention is examined in a randomized controlled step-wedge design, in which approximately 1.000 children are followed up to the age of 24 months. The VIPP-PUF intervention is hypothesized to reduce mental health problems at ages 24 months among infants with high levels of cognitive and regulatory problems at age 9-10 months, (primary outcome). Also, it is hypothesized that among children with high levels of cognitive and regulatory vulnerabilities at age 9-10 months, adding the VIPP-PUF intervention to treatment as usual at age 9-10 months, will reduce infants' cognitive and regulatory problems; promote healthy weight development; reduce parents' experiences of stress; promote sensitive parenting and promote parents' feeling of competence and relatedness.
