Generation Healthy Kids: Protocol for a cluster-randomized controlled trial of a multi-component and multi-setting intervention to promote healthy weight and wellbeing in 6-11-year-old children in Denmark.

Background: Childhood obesity can have significant negative consequences for children's wellbeing and long-term health. Prior school-based interventions to prevent child overweight and obesity have shown limited effects, highlighting the necessity for comprehensive approaches addressing complex drivers of childhood obesity. "Generation Healthy Kids" (GHK) is a multi-setting, multi-component intervention to promote healthy weight development, health and wellbeing in Danish children aged 6-11 years.

Feasibility and acceptability of school-based intervention components to promote healthy weight and well-being among 6-11-year-olds in Denmark: mixed methods findings from the Generation Healthy Kids feasibility study.

Background: Overweight and obesity among children is a serious public health challenge worldwide which may lead to a range of negative physical, mental, and social consequences in childhood and later in life. There is a strong need for developing new innovative, integrated approaches and programs which can prevent overweight in children effectively and can be embedded into everyday practices. The Generation Healthy Kids intervention is a multi-component, multi-setting intervention aiming to promote healthy weight and well-being in children aged 6-11 years in Denmark.

Generalizability and performance of methods to detect non-wear with free-living accelerometer recordings.

Wearable physical activity sensors are widely used in research and practice as they provide objective measures of human behavior at a low cost. An important challenge for accurate assessment of physical activity behavior in free-living is the detection non-wear. Traditionally, heuristic algorithms that rely on specific interval lengths have been employed to detect non-wear time; however, machine learned models are emerging.

Exploring implementation of a nationwide requirement to increase physical activity in the curriculum in Danish public schools: a mixed methods study.

Background: In 2014, the Danish Government introduced a wide-ranging school reform that applied to all public schools in Denmark. A distinctive feature of the reform was that it became mandatory to implement an average of 45 min of daily physical activity within the curriculum. Using the RE-AIM framework as an evaluation tool, the objective of the current study was to evaluate the reach, effectiveness, adoption, implementation, and maintenance of mandatory physical activity within the curriculum at ten Danish schools.

Temporal Alignment of Dual Monitor Accelerometry Recordings.

Combining accelerometry from multiple independent activity monitors worn by the same subject have gained widespread interest with the assessment of physical activity behavior. However, a difference in the real time clock accuracy of the activity monitor introduces a substantial temporal misalignment with long duration recordings which is commonly not considered. In this study, a novel method not requiring human interaction is described for the temporal alignment of triaxial acceleration measured with two independent activity monitors and evaluating the performance with the misalignment manually identified.

Protocol for evaluating the impact of a national school policy on physical activity levels in Danish children and adolescents: the PHASAR study - a natural experiment.

Background: In 2014 the Danish Government introduced a wide-ranging school reform that applies to all public schools in Denmark. The reform involves changes in several aspects of the school structure and content. In a physical activity promotion perspective, a distinctive feature of the school reform is that it has become mandatory to integrate an average of 45 min of daily physical activity in the regular school day.

The association between serum brain-derived neurotrophic factor and a cluster of cardiovascular risk factors in adolescents: The CHAMPS-study DK.

Background And Objective: Cardiovascular disease and type 2 diabetes pose a global health burden. Therefore, clarifying the pathology of these risk factors is essential. Previous studies have found positive and negative associations between one or more cardiovascular risk factors and brain-derived neurotrophic factor (BDNF) probably due to diverse methodological approaches when analysing peripheral BDNF levels.
