A small but growing number of voices have begun to raise questions about the current direction of children's geographies as a subfield and its status within the wider discipline. This article intervenes in these emerging discussions to examine the status of debate itself within children's geographies. I argue that children's geographies over the past decade has operated primarily in a consensus-based mode, with a number of potential tensions and differences between practitioners masked as a result. I develop the example of notions of children's competent social agency, a core theoretical assumption that is rarely interrogated in much depth. In closing, I pose questions regarding several contemporary political issues concerning children's agency about which geographers have had surprisingly little to say. I suggest that explicitly addressing some of these vexing issues would contribute to a richer state of debate within children's geographies. 相似文献

This paper describes global (whole of Leeds) and local (super output area) analyses of the relationship between childhood obesity and many 'obesogenic environment' variables, such as deprivation, urbanisation, access to local amenities, and perceived local safety, as well as dietary and physical activity behaviours. The analyses identify the covariates with the strongest relationships with obesity, and highlight variation in these relationships across Leeds, thus identifying 'at-risk' populations. This paper seeks to demonstrate the importance of analysis at the micro-level in order to provide health planners with additional information with which to tailor interventions and health policies to prevent childhood obesity. 相似文献

Obesity is a growing epidemic in the United States. Walkable neighborhoods, characterized as having the three Ds of walkability (population Density, land use Diversity, and pedestrian-friendly Design), have been identified as a potentially promising factor to prevent obesity for residents. Past studies examining the relationship between obesity and walkability vary in geographic scales of neighborhood definitions and methods of measuring the three Ds. To better understand potential influences of these sometimes arbitrary choices, we test how four types of alternative measures of land use diversity measured at three geographic scales relate to body mass index for 4,960 Salt Lake County adults. Generalized estimation equation models demonstrate that optimal diversity measures differed by gender and geographic scale and that integrating walkability measures at different scales improved the overall performance of models. 相似文献

论文基于中国25个省份内635个社区的29586个成年居民2010—2016年的纵向追踪调查数据,分别利用非线性发展模型和多层Logistic回归模型,阐释中国居民超重肥胖情况的变化趋势,同时探究其在个体与环境交互作用下的影响机制。研究发现：① 以身体质量指数衡量的中国成人超重肥胖发生风险逐年增加,其中女性、年龄、有配偶人群、日均锻炼时长负向作用于成人身体质量指数增长速率;② 中国成人超重肥胖差异具有多层级性,个体层面社会经济属性、饮食习惯和行为方式,社区层面建成环境和自然环境,省域层面城市化水平,均能影响成人超重肥胖发生;③ 不同层级间超重肥胖影响因子具有交互作用关系,环境能通过影响个体心理状态及行为选择对个体健康结果的作用,间接作用于居民超重肥胖结果。研究结果旨在帮助中国成人居民达到更好的健康状态,以及为相关政府部门制定促进人口健康的政策提供理论依据。 相似文献

This paper examines the statewide relationship between built environment and obesity at the county scale by using the Geographically Weighted Regression (GWR) method. The independent variables include three built environment factors – street connectivity, walk score, fast-food/full-service restaurants ratio – and two sociodemographic variables, race heterogeneity and poverty rate. The urban influence is considered as a covariate in the analysis. Through the regression model we found that walk score and street connectivity are negatively related to obesity, poverty rate and metro are positively related, and the fast-food/full-service restaurants ratio is not significant. A regionalization method is used to group US counties to regions based on their GWR coefficients. Qualitative inferences of policies are made available to facilitate better understanding of the obesity problem associated with the built environment in these regions. 相似文献

'Gluttony or sloth': critical geographies of bodies and morality in (anti)obesity policy 总被引：1，自引：0，他引：1
Bethan Evans 《Area》2006,38(3):259-267
In many countries, obesity is high on public health policy agendas, and geographical research has begun to engage with obesity. However, obesity is a highly contested term, and recent debates about geographers' engagement with policy, and critical discussions of the presence of bodies in medical geography, bear great relevance for developing a critical perspective on dominant 'obesity discourse'. Through a critical reading of a recent UK policy document, this paper considers the presence of bodies in (anti)obesity campaigns, calling for a more critical approach to the medicalization of body size to be central to future geographical work on obesity. 相似文献
