Supporting schools during the implementation of the health-promoting school approach: The roles of a healthy school advisor.

Introduction: The health-promoting school (HPS) approach was developed by the World Health Organization to create health promotion changes in the whole school system. Implementing the approach can be challenging for schools because schools are dynamic organizations with each a unique context. Many countries worldwide have a health promotion system in place in which healthy school (HS) advisors support schools in the process of implementing the HPS approach. Even though these HS advisors can take on various roles to provide support in an adaptive and context-oriented manner, these roles have not yet been described. The current study aims to identify and describe the key roles of the HS advisor when supporting schools during the dynamic process of implementing the HPS approach. Methods: The study was part of a project in which a capacity-building module was developed for and with HS advisors in the Netherlands. In the current study, a co-creation process enabled by participatory research was used in which researchers, HS advisors, national representatives, and coordinators of the Dutch HS program participated. Co-creation processes took place between October 2020 and November 2021 and consisted of four phases: (1) a narrative review of the literature, (2) interviews, (3) focus groups, and (4) a final check. Results: Five roles were identified. The role of "navigator" as a more central one and four other roles: "linking pin," "expert in the field," "critical friend," and "ambassador of the HPS approach." The (final) description of the five roles was recognizable for the HS advisors that participated in the study, and they indicated that it provided a comprehensive overview of the work of an HS advisor in the Netherlands. Discussion: The roles can provide guidance to all Dutch HS advisors and the regional public health organizations that employ them on what is needed to provide sufficient and context-oriented support to schools. These roles can inspire and guide people from other countries to adapt the roles to their own national context.

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. In designing and/or re-designing school-based interventions, it is important to enhance optimal context-oriented implementation adaptation by involving the complex adaptive school system. This paper elaborates on the way of dealing with the dynamic implementation context of the educational programme "Krachtvoer" (ENG: "Power food") for prevocational schools, how the programme can be adapted to each unique implementation context, and how the programme can be progressively kept up to date. Following a co-creation-guided approach with various intersectoral stakeholders within and outside the school setting, action-oriented mixed research methods (i.e., observations, semi-structured interviews, focus group interviews, programme usage monitoring, and questionnaires) constantly provide input to develop the programme and its implementation strategy via continuous micro-process cycles. Successful co-creation of school-based health promotion seems to be dependent on proper intersectoral cooperation between research and practice communities, a national partner network that can provide project-relevant insights and establish capacity building aimed at improving contextual fit, and a time-investment balance in and between sectors.

[Effects and costs of The Healthy Primary School of the Future]. / De effecten en kosten van de Gezonde Basisschool van de Toekomst.

OBJECTIVE: To study school lifestyle interventions for elementary school children (The Healthy Primary School of the Future). RESEARCH QUESTION: What are the effects of the introduction of increased physical activity with or without healthy nutrition on health behaviour and BMI of young children and what are the costs of this program? DESIGN: Prospective controlled non-randomized study with nearly 1700 children in Parkstad (South-East Netherlands). RESULTS: Preliminary results after two years show that the combination of increased physical activity and healthy nutrition result in a decreased BMIz-score (-0.036), increased physical activity alone in hardly any change (-0.10) while in the control group the BMIz-score increased (0.052). The net societal costs of the combination of physical activity and health nutrition costs were 1 euro per child per day. CONCLUSION: The study contributes to the increasing amount of evidence proving that lifestyle interventions are effective in reducing the obesity epidemic. Future studies will show whether a weight reduction in children will result in the prevention of chronic disease later on in life and what the cost reduction related to this result will be.

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

Background: This study examines the social return on investment (SROI) of the "Healthy Primary School of the Future" initiative after 2 years. Methods: 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 (N = 1,676 children) of both school environments (four schools) compared to control schools (four schools). Investments and outcomes were grouped within the healthcare, education, household & leisure, and labor & social security sector. Outcomes that could be expressed in monetary terms were used for the calculation of social return on investment. Results: HPSF and PAS created outcomes for the healthcare sector by favorable changes in health behaviors, body mass index [both significant], and medical resource use [not significant]. Outcomes for the education sector included a favorable impact on perceived social behaviors and school satisfaction, and absenteeism from school [latter not significant], and more engagement with the community was experienced. The per child investments, €859 (HPSF) and €1017 (PAS), generated a benefit of €8 (HPSF) and €49 (PAS) due to reduced school absenteeism and medical resource use. Conclusions: Within 2 years of intervention implementation, the HPSF initiative created outcomes in several sectors, but the benefits did not outweigh the investments. Follow-up assessments as well as modeling long-term outcomes are needed to assess the total value of the interventions. Until then, the SROI framework can inform strategies for obtaining stakeholder support and intervention implementation. Trial registration: The study was registered in the ClinicalTrials.gov database on 14 June 2016 (NCT02800616).

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. DESIGN: A longitudinal quasi-experimental design. SETTING: Four intervention and four control schools participated; located in a low socioeconomic status region in the Netherlands. PARTICIPANTS: 1676 children (aged 4-12 years). INTERVENTIONS: HPSF uses a contextual systems approach and includes health-promoting changes in the school. Central to HPSF is the provision of a daily healthy lunch and structured physical activity sessions each day. Two intervention schools implemented both changes (full HPSF), two intervention schools implemented only the physical activity change (partial HPSF). MAIN OUTCOME MEASURES: BMI z-score, determined by measurements of children's height and weight at baseline, after 1 and 2 years follow-up. RESULTS: The intervention effect was significant after 1-year follow-up in the partial HPSF (standardised effect size (ES)=-0.05), not significant in the full HPSF (ES=-0.04). After 2 years follow-up, BMI z-score had significantly decreased in children of both the full HPSF (ES=-0.08) and the partial HPSF (ES=-0.07) compared with children of the control schools, whose mean BMI z-score increased from baseline to 2 years. None of the potential effect modifiers (gender, baseline study year, socioeconomic status and baseline weight status) were significant. CONCLUSIONS: HPSF was effective after 1 and 2 years follow-up in lowering children's BMI z-scores. No specific subgroups of children could be identified who benefitted more from the intervention. TRIAL REGISTRATION NUMBER: NCT02800616.

Unravelling the Effects of the Healthy Primary School of the Future: For Whom and Where Is It Effective?

The 'Healthy Primary School of the Future' (HPSF) aims to integrate health and well-being within the whole school system. This study examined the two-year effects of HPSF on children's dietary and physical activity (PA) behaviours at school and at home and investigated whether child characteristics or the home context moderated these effects. This study (n = 1676 children) has a quasi-experimental design with four intervention schools, i.e., two full HPSF (focus: nutrition and PA), two partial HPSF (focus: PA), and four control schools. Measurements consisted of accelerometry (Actigraph GT3X+) and questionnaires. Favourable effects on children's dietary and PA behaviours at school were found in the full HPSF; in the partial HPSF, only on PA behaviours. Children in the full HPSF did not compensate at home for the improved health behaviours at school, while in the partial HPSF, the children became less active at home. In both the full and partial HPSF, less favourable effects at school were found for younger children. At home, less favourable effects were found for children with a lower socioeconomic status. Overall, the effect of the full HPSF on children's dietary and PA behaviours was larger and more equally beneficial for all children than that of the partial HPSF.

The Moderating Role of the School Context on the Effects of the Healthy Primary School of the Future.

Background: The current study investigated the moderating role of the school context on the effects of a Dutch health promoting school initiative on children's health and health behaviors. Methods: The study used a mixed-methods design. The school context (n = 4) was assessed by the characteristics of the school population, teacher's health-promoting (HP) practices, implementers' perceived barriers, school's HP elements, and dominating organizational issues. Outcomes included objectively assessed BMI z-scores and physical activity (PA), and parent and child-reported dietary intake. Analyses included linear mixed models (four intervention schools versus four control schools), and qualitative comparisons between intervention schools with similar HP changes. Results: Effects on outcomes varied considerably across schools (e.g., range in effect size on light PA of 0.01-0.26). Potentially moderating contextual aspects were the child's socioeconomic background and baseline health behaviors; practices and perceived barriers of employees; and organizational issues at a school level. Conclusions: Similar HP changes lead to different outcomes across schools due to differences in the school context. The adoption of a complex adaptive systems perspective contributes to a better understanding of the variation in effects and it can provide insight on which contextual aspects to focus on or intervene in to optimize the effects of HP initiatives.

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). SES was measured by maternal and paternal education and household income (adjusted for family size). Health outcomes were body mass index (BMI) z-score, health resource use, school absenteeism, health-related quality of life and psychosocial health, measured over 2 years of follow-up (2015-2017). Health behaviours included physical activity, and consumption of fruits, vegetables and sweetened beverages. Associations between SES and baseline health behaviours were examined, and mixed models for repeated measures were used to assess associations between SES and health outcomes over 2 years of follow-up. RESULTS: A high socioeconomic background was significantly associated with better health outcomes (all outcomes). For example, children with a low SES had higher BMI z-scores (beta coefficient: 0.42, 95% CI 0.22 to 0.62) and higher consumption healthcare costs (ratio of mean costs: 2.21, 95% CI 1.57 to 3.10). Effects of SES changed very little after controlling for health behaviours. DISCUSSION: Our findings strongly suggest that socioeconomic background has a pervasive impact on disparities in child health, but gives little support to the idea that social inequalities in child health can be tackled by means of lifestyle interventions.

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 study (n = 1676 children) has a quasi-experimental design with four intervention schools, i.e., two full HPSF (focus: nutrition and PA) and two partial HPSF (focus: PA), and four control schools. Accelerometers and child- and parent-reported questionnaires were used at baseline, after 1 (T1) and 2 (T2) years. Mixed-model analyses showed significant favourable effects for the full HPSF versus control schools for, among others, school water consumption (effect size (ES) = 1.03 (T1), 1.14 (T2)), lunch intake of vegetables (odds ratio (OR) = 3.17 (T1), 4.39 (T2)) and dairy products (OR = 4.43 (T1), 4.52 (T2)), sedentary time (ES = -0.23 (T2)) and light PA (ES = 0.22 (T2)). Almost no significant favourable effects were found for partial HPSF compared to control schools. We conclude that the full HPSF is effective in promoting children's health behaviours at T1 and T2 compared with control schools. Focusing on both nutrition and PA components seems to be more effective in promoting healthy behaviours than focusing exclusively on PA.

Socioeconomic multi-domain health inequalities in Dutch primary school children.

Background: This study assesses socio-economic health inequalities (SEHI) over primary school-age (4- to 12-years old) across 13 outcomes (i.e. body-mass index [BMI], handgrip strength, cardiovascular fitness, current physical conditions, moderate to vigorous physical activity, sleep duration, daily fruit and vegetable consumption, daily breakfast, exposure to smoking, mental strengths and difficulties, self-efficacy, school absenteeism and learning disabilities), covering four health domains (i.e. physical health, health behaviour, mental health and academic health). Methods: Multilevel mixed effect (linear and logistic) regression analyses were applied to cross-sectional data of a Dutch quasi-experimental study that included 1403 pupils from nine primary schools. Socioeconomic background (high-middle-low) was indicated by maternal education (n = 976) and parental material deprivation (n = 784). Results: Pupils with higher educated mothers had lower BMIs, higher handgrip strength and higher cardiovascular fitness; their parents reported more daily fruit and vegetable consumption, daily breakfast and less exposure to smoking. Furthermore these pupils showed less mental difficulties and less school absenteeism compared with pupils whose mothers had a lower education level. When using parental material deprivation as socio-economic indicator, similar results were found for BMI, cardiovascular fitness, sleep duration, exposure to smoking and mental strengths and difficulties. Socio-economic differences in handgrip strength, cardiovascular fitness and sleep duration were larger in older than in younger pupils. Conclusions: Childhood SEHI are clearly found across multiple domains, and some are larger in older than in younger pupils. Interventions aiming to tackle SEHI may therefore need a comprehensive and perhaps more fundamental approach.

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

Background: 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. Properties of CARA are its focus on contextual differences and the use of monitoring and feedback to support and evaluate the process of change. The aim of this article is to describe the use of the approach. Methods: Four schools (each with 200⁻300 children, aged 4⁻12 years) were included; all located in low socio-economic status areas in the south of the Netherlands. Data collection methods include interviews, observations, questionnaires, and health and behavioural measurements. Research contributions include giving feedback and providing schools with a range of possibilities for additional changes. The contextual data we examine include schools' health promoting elements, practices of teachers and parents, dominating organisational issues, and characteristics of the student population; process data include the presence of potential barriers to changes. Discussion: CARA is an adaptive research approach that generates knowledge and experiences on how to deal with health promotion in complex systems. We think this approach can set an example for research efforts in comparable initiatives.

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. Height, weight, waist circumference, aerobic fitness, and self-reported dietary and PA behavior were assessed at baseline (T(0)), immediately after the 13-week RealFit intervention (T(1)), after 5 months (T(2)), and 1 year (T(3)) of follow-up. A total of 86 adolescents participated in the intervention group. The control group (n=32) comprised overweight adolescents who did not receive any treatment. RESULTS: One year after the RealFit intervention, significant decreases in BMI z-score (mean difference [MD]: -0.39) and waist circumference (MD, -3.24) were found. The comparison between the intervention and control groups, controlling for confounders, resulted in a significant difference (BMI z-score: -0.41; 95% confidence interval [CI]: -0.67 to -0.15; waist circumference: -8.07; 95% CI: -11.58 to -4.56). The results for dietary and PA behavior consistently showed favorable changes in the intervention group. CONCLUSIONS: The RealFit intervention appears to have significant favorable long-term effects on BMI z-score and waist circumference. These changes in body composition obviously represent changes in adolescents' energy balance-related behavior. Taking all results and limitations into account, it may cautiously be concluded that RealFit is an effective weight loss intervention.
