Overweight Childhood

Investigators propose to study youth across the spectrum of body mass index (BMI) and dysglycemia. This approach will allow investigators to disentangle the relationship of key features of type 2 diabetes (T2D) risk (e.g. obesity) with intermediary physiologic changes (e.g. insulin resistance, inflammation, β-cell dysfunction and dysglycemia) that pose a risk for the brain. Investigators will determine which of these factors are most associated with differences in brain structure and function among groups, over time, and how these effects differ from normal neurodevelopment.

The aim of the Bloom Study is to promote healthy weight development among infants through a home-based health promoting intervention implemented in the Danish setting of community health nurses. The intervention begins during pregnancy and runs until the child reaches the age of 30 months. The Bloom Intervention was developed over a six-year period from 2017 to 2023 according to the Intervention Mapping approach and based on a co-creation process. The Bloom Intervention is evaluated in a cluster-randomized trial involving 22 Danish municipalities (11 intervention and 11 control). All children born from first-time mothers over a period of 12 months are invited to participate.

The goal of this study is to evaluate the effectiveness of CHAMPION ("Comparative-effectiveness of a Healthy lifestyle and Asthma Management Program, In-person vs ONline"), a primary care-based intervention to address childhood obesity and asthma, and test the effectiveness of a telehealth-only version of the program. Intensive Health Behavior and Lifestyle Treatment (IHBLT), when delivered via telehealth vs. in-person among children with overweight or obesity and persistent asthma.
