Noncomprehensive and Intermittent Obesity-Related School Programs and Policies May Not Work: Evidence from the COMPASS Study

Evaluation of Problem-Based Learning Experiences Addressing Health Promotion in the Fourth Grade of Primary School

BACKGROUND

The global issues of overweight and sedentary lifestyles require comprehensive responses from health systems. Despite this, health education remains fragmented and sporadic. This study aims to target primary school children to instil healthy habits using active learning strategies, with a specific focus on promoting a healthy diet and physical activity.

METHODS

This study employed problem-based learning (PBL) projects with fourth-grade primary students to encourage the acquisition of healthy habits. Conducted over four consecutive years at a two-line school, the study utilised an opportunity sample, evaluating intervention and control groups by comparing their corresponding scores. The control groups consisted of 54 students, while the intervention group included 159 students. Data collection involved pre-test and post-test questionnaires to measure outcomes.

RESULTS

Differential evaluation scores revealed significantly higher results in the intervention groups compared to the control groups, with an average score increase of 3.62 points in control groups and 6.94 points in intervention groups, particularly in attitudinal competencies. The strategies employed facilitated the development of crucial skills such as information search, synthesis, representation, analysis, decision making, teamwork, and intrapersonal awareness. Additionally, they significantly broadened the knowledge acquired regarding healthy habits.

CONCLUSIONS

The problem-based learning approach proved effective in helping children understand the importance of making healthy choices and encouraged the integration of such habits into their daily lives. These findings suggest that active learning strategies can significantly enhance health education and promote long-term healthy behaviours among primary school children.

Understanding children's perceptions of, and priorities for, healthy neighbourhoods in Aotearoa New Zealand: study protocol for a cross-sectional study

INTRODUCTION

Neighbourhood environments can have significant and enduring impacts on children's physical, psychological and social health. Environments can impact health through promoting or hindering physical activity, active travel, and healthy eating in addition to opportunities for social interaction, cognitive development, rest and relaxation. There is a paucity of research that has examined neighbourhood and health priorities, strengths and needs from the perspectives of the community, and even less that has focused on the perspectives of children within communities. The aim of this article is to describe the research protocol for a project to gather child-identified needs and strengths-based solutions for promoting child health and well-being in urban neighbourhood environments.

METHODS AND ANALYSIS

This participatory research project is designed to partner with children in school settings in Tāmaki Makaurau Auckland and Ōtepoti Dunedin, Aotearoa New Zealand. An abundant communities approach will be used with children to identify needs and strengths related to neighbourhoods and health. Specific methods including collaborative, creative, play-based methods such as concept-mapping activities and co-creation of final dissemination material on the key messages are described. Plans for researcher reflections, data analysis and dissemination are also detailed.

ETHICS AND DISSEMINATION

This research has been approved by the University of Auckland Human Participants Ethics Committee. Results will be disseminated through child and researcher co-created output, a technical report and academic journal articles. By using evidence-based child-centred approaches to knowledge generation, we anticipate the research will generate new localised insights about children's preferences and needs for healthy neighbourhoods which will be shared with stakeholders in planning and practice. The detailed session protocol including critical researcher reflections is shared in this manuscript for application, development and refinement in future research.

The User-Program Interaction: How Teacher Experience Shapes the Relationship Between Intervention Packaging and Fidelity to a State-Adopted Health Curriculum

Intervention effects observed in efficacy trials are rarely seen when programs are broadly disseminated, underscoring the need to better understand factors influencing fidelity. The Michigan Model for Health™ (MMH) is an evidence-based health curriculum disseminated in schools throughout Michigan that is widely adopted but delivered with limited fidelity. Understanding implementation determinants and how they influence fidelity is essential to achieving desired implementation and behavioral outcomes. The study surveyed health teachers throughout Michigan (n = 171) on MMH implementation, guided by the Consolidated Framework for Implementation Research. We investigated relationships between context, intervention and provider factors and dose delivered (i.e., the proportion of curriculum delivered by teachers), a fidelity dimension. We also examined whether intervention factors were moderated by provider factors to influence fidelity. Our results indicated that program packaging ratings were associated with dose delivered (fidelity). We also found that this relationship was moderated by teacher experience. The strength of this relationship diminished with increasing levels of experience, with no relationship among the most experienced teachers. Intervention adaptability was also associated with dose delivered. We found no association between health education policies (context), provider beliefs, and dose delivered. Intervention factors are important determinants of fidelity. Our results suggest that providers with more experience may need materials tailored to their knowledge and skill level to support materials' continued usefulness and fidelity long-term. Our results also suggest that promoting adaptability may help enhance fidelity. Implementation strategies that focus on systematically adapting evidence-based health programs may be well suited to enhancing the fidelity of the MMH curriculum across levels of teacher experience.
