The group has a large focus on digital health and has many years’ experience in developing tools for both maternity and child healthcare. The group consists of 20 individuals (PhD students, post-docs, as well as junior and senior researchers).

The doctoral student project and the duties of the doctoral student

This PhD project focuses on the promotion of healthy lifestyle behaviours in the first 2000 days of life to prevent overweight and obesity using mobile health (mHealth) interventions in primary child healthcare. The first part of this project aims to study the novel implementation of an evidence-based program for obesity prevention and the promotion of healthy lifestyle behaviours in young children within primary child healthcare using a cluster randomized controlled trial. The second part of the project will evaluate the feasibility of a parent-focused mHealth intervention to promote healthy lifestyle behaviours from infancy in a pilot randomized controlled trial. The PhD candidate’s responsibilities will include coordinating data collection, processing data, conducting statistical analysis, developing intervention content, as well as writing scientific articles for the thesis. This project includes both quantitative and qualitative components.
