Since the '80s, global prevalence of Childhood Overweight and Obesity (COO) increased sharply. Due to its epidemic proportions and long-termimpacts on health and wellbeing of children, the WHO considers tackling obesity to be one of the most serious public health challenges of our century.Despite the plethora of multilevel COO research, its relation with characteristics of the built environment inciting energy expenditure is still insufficientlyunderstood. With an innovative approach - a sequential explanatory mixed methods design - I want to research this complex interplay between placeand COO in a PhD project. In a first, quantitative sequence, piloted during my MPhil, a spatial epidemiological study will be carried out. Relying on GISand statistical methods, general trends in the relation between COO in London schoolchildren and the characteristics of their (school) neighbourhoodsand commuting routes that foster/hinder physical activity will be searched. This is followed by a qualitative research, producing contextual andcomplementary information on these trends. Go-along interviews, NVivo, accelerometers and Qualitative GIS will be applied to hear and analyse thechildren's narratives and to explore their physical movements as they unfold in real time and space. In the final, integrative phase, the quantitativefindings will be expanded with the qualitative ones, aiming to produce knowledge that can serve public health policies and interventions to tackle COO.

自80年代以来，全球儿童超重和肥胖(COO)患病率急剧上升。由于肥胖的流行比例和对儿童健康和福祉的长期影响，世卫组织认为解决肥胖问题是本世纪最严重的公共卫生挑战之一。尽管有太多多层次的COO研究，但它与引发能源消耗的建筑环境特征之间的关系仍然没有得到足够的了解。通过一种创新的方法--顺序解释性混合方法设计--我想在一个博士项目中研究Place和COO之间的这种复杂的相互作用。在我担任MPHIL期间试行的第一个定量序列中，将进行空间流行病学研究。依靠地理信息系统和统计方法，将探索伦敦学童的首席营运官与他们(学校)社区的特征以及促进/阻碍身体活动的通勤路线之间的关系的一般趋势。随后进行了定性研究，提供有关这些趋势的背景信息和补充信息。后续访谈、NVivo、加速计和定性地理信息系统将用于听取和分析儿童的叙述，并探索他们在实时和空间展开时的身体动作。在最后的综合阶段，将用定性结果扩展定量结果，目的是产生能够服务于公共卫生政策和干预措施的知识，以解决COO问题。
