Schools are key settings for childhood obesity prevention, and the location for many intervention studies. This qualitative study aims to explore parent and child experiences of the WAVES study obesity prevention intervention, in order to gain understanding of the mechanisms by which the intervention results in behaviour change, and provide context to support interpretation of the main trial results.
Focus groups were held with 30 parents and 62 children (aged 6-7 years) from primary schools in the West Midlands, UK. Data analysis (conducted using NVivo 10) was guided by the Framework Approach.
Three over-arching themes were identified: 'Impact', 'Sustainability' and 'Responsibilities', under which sub-themes were determined. Participants were supportive of the school-based intervention. Parental involvement and the influential role of the teacher were seen as key ingredients for success in promoting consistent messages and empowering some parents to make positive behavioural changes at home. Parents recognised that whilst they held the primary responsibility for obesity prevention in their children, they faced a number of barriers to healthier lifestyles, and agreed that schools have an important role to play.
This study enabled us to better understand aspects of the WAVES study intervention programme that have the potential to initiate positive behaviour changes in families, and indicated that a combination of pathways influenced such changes. Pathways included: increasing capability through improving knowledge and skills of children and parents; increasing motivation through parental empowerment and role modelling; and the direct provision of opportunities to lead healthier lifestyles. Strategies to sustain behaviour changes, and the school role in supporting these, are important considerations.
学校是预防儿童肥胖的关键场所，也是许多干预研究的开展地点。这项定性研究旨在探索家长和儿童在WAVES研究肥胖预防干预中的经历，以便了解干预导致行为改变的机制，并为解释主要试验结果提供背景信息。
对来自英国西米德兰兹郡小学的30名家长和62名儿童（6 - 7岁）进行了焦点小组访谈。数据分析（使用NVivo 10进行）以框架法为指导。
确定了三个总体主题：“影响”、“可持续性”和“责任”，并在其下确定了子主题。参与者对基于学校的干预表示支持。家长的参与和教师的影响力被视为成功推广一致信息以及促使一些家长在家中做出积极行为改变的关键因素。家长认识到，虽然他们对预防孩子肥胖负有主要责任，但他们在追求更健康生活方式方面面临一些障碍，并认同学校可发挥重要作用。
本研究使我们能够更好地理解WAVES研究干预计划中有可能在家庭中引发积极行为改变的方面，并表明多种途径共同影响了这些改变。这些途径包括：通过提高儿童和家长的知识与技能来增强能力；通过赋予家长权力和树立榜样来增强动力；以及直接提供引领更健康生活方式的机会。维持行为改变的策略以及学校在支持这些策略方面的作用是重要的考虑因素。
