The Bloom Study - a Safe and Healthy Start in Life

The Bloom Study is a large Danish trial testing whether an enhanced support program delivered through community health nurses — starting during pregnancy and continuing until a child is 30 months old — can help children maintain a healthy weight during infancy and early childhood. The program covers feeding, physical activity, screen time, sleep, and emotional wellbeing, with a strong emphasis on reaching all families regardless of background and involving fathers and partners. All first-time mothers in participating Danish municipalities who are at 20 weeks of pregnancy between November 2024 and October 2025 are invited to participate, with the only exclusion being inability to receive digital correspondence. Families in the intervention group will receive extra home visits, phone check-ins, parent group sessions, and access to an educational video library, with the child's BMI measured at 36 months as the main outcome. This summary was prepared to help patients understand the study in plain language.
