Study protocol for a cluster-randomized controlled trial of a universal home-based, multi-component intervention to promote healthy weight development in children during infancy and toddlerhood in denmark: the bloom study.
Article in BMC public health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT06705400 (The Bloom Study - a Safe and Healthy Start in Life), which is not on this map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

Abstract
backgroundChild overweight and obesity are major public health challenges associated with poor physical, psychological, and social health through life. This protocol describes the study design for the Bloom Study, an evaluation of a theory- and evidence-based intervention addressing infancy and toddlerhood (age 0-3 years) to promote healthy weight development among children in Denmark.
methodsThe Bloom intervention is evaluated through an open-label, two-arm, cluster-randomized wait-list control trial, with 22 municipalities randomly allocated to 11 intervention and 11 control municipalities. All first-time families within one year are invited (approximately 3200 families). The intervention was developed using the Intervention Mapping protocol and a thorough co-creation process. It is delivered through the Danish community health nursing system and includes four main components: (1) Home visits, (2) Proactive telephone consultations, (3) Parent groups for both parents, and (4) A video library. The intervention begins during pregnancy (between weeks 22-24) and continues until the child is 30 months. The primary outcome measure is the BMI z-score at 36 months of age. Secondary outcomes relate to the key determinants of child weight development targeted by the Bloom intervention, including food and meals, sleep, movement and motor skills, screen use, and family sense of security. A comprehensive mixed methods process evaluation and a health economic evaluation will also be conducted. DISCUSSION: The protocol outlines the evaluation of a theory- and evidence-based intervention aimed at promoting healthy weight development in infants and toddlers in Denmark. Overall, the study has the potential to inform future health promotion initiatives at the municipal level, supporting healthy weight development during early childhood.
