Co-Creation Approach with Action-Oriented Research Methods to Strengthen "Krachtvoer"; A School-Based Programme to Enhance Healthy Nutrition in Adolescents.

In recent years, the nutritional pattern of the Dutch adolescent has cautiously improved. However, progress can be gained if more Dutch adolescents adhere to the nutritional guidelines. School-based initiatives offer opportunities to deal with the unhealthy eating behaviours of adolescents via nutrition educational interventions.

The Short-Term Value of the "Healthy Primary School of the Future" Initiative: A Social Return on Investment Analysis.

This study examines the social return on investment (SROI) of the "Healthy Primary School of the Future" initiative after 2 years. Healthy Primary Schools of the Future (HPSF) provide a healthy lunch and daily structured physical activity sessions, whereas Physical Activity Schools (PAS) focus on physical activity only. We evaluated the 2-years investments and effects ( = 1,676 children) of both school environments (four schools) compared to control schools (four schools).

Can the Healthy Primary School of the Future offer perspective in the ongoing obesity epidemic in young children? A Dutch quasi-experimental study.

Objectives: Schools play an important role in promoting healthy behaviours in children and can offer perspective in the ongoing obesity epidemic. The 'Healthy Primary School of the Future' (HPSF) aims to improve children's health and well-being by enhancing school health promotion. The current study aims to assess the effect of HPSF on children's body mass index (BMI) z-score after 1 and 2 years follow-up and to investigate whether HPSF has different effects within specific subgroups of children.

Longitudinal analysis of health disparities in childhood.

Objective: Combatting disparities in health outcomes among children is a major public health concern. This study focuses on two questions: (1) To what extent does socioeconomic status (SES) contribute to disparities in health outcomes? and (2) To what extent can social inequalities in health outcomes be explained by differences in children's health behaviours?

Design: This study included 2-year follow-up data of 1259 children (4-12 years of age) who participated in the 'Healthy Primary School of the Future' project (ClinicalTrials.gov NCT02800616).

One- and Two-Year Effects of the Healthy Primary School of the Future on Children's Dietary and Physical Activity Behaviours: A Quasi-Experimental Study.

Schools can help to improve children's health. The 'Healthy Primary School of the Future' (HPSF) aims to sustainably integrate health and well-being into the school system. This study examined the effects of HPSF on children's dietary and physical activity (PA) behaviours after 1 and 2 years' follow-up.

The Healthy Primary School of the Future: A Contextual Action-Oriented Research Approach.

Schools can play an important role in promoting children's health behaviours. A Dutch initiative, 'The Healthy Primary School of the Future', aims to integrate health and well-being into the school system. We use a contextual action-oriented research approach (CARA) to study the implementation process.

Long-term effects of the RealFit intervention on body composition, aerobic fitness, and behavior.

Background: RealFit is a 13-week weight reduction program for youth that focuses on nutrition, physical activity (PA), psychology, and parental participation. The short-term effectiveness of the RealFit intervention, in terms of body composition, aerobic fitness, and dietary and PA behavior, having been proven, the present study evaluated the long-term effects of the intervention.

Methods: The study had a quasi-experimental design.
