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

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

Understanding the relationships between obesity and socioeconomic status (SES) among school children and the spatial variation of such relationship is essential for developing appropriate intervention strategies. In this study, we employed Local Entropy Map (LEM) to explore the spatial patterns of the relationship at school district level in Texas. Children's obesity was measured by Body Mass Index (BMI). The BMI data for this study were obtained from Physical Fitness Assessment Initiative (PFAI) program that has been coordinated by Texas Education Agency (TEA). SES was described by six variables, which were further reduced into two factors, namely Household SES and Neighborhood SES. The study period was 2012–2013 academic year. LEM analyses revealed clear spatial variation of the relationship between obesity and SES at school-district level. In particular, the prevalence of obesity among school children was found to be significantly related to Household SES and Neighborhood SES in four regions in Texas. These four regions are centered in major metropolitan areas in Texas, including San Antonio, Dallas-Fort Worth, Houston, and Lubbock. Further regression analyses showed variation of the relationship across these four regions. Obesity among school children in Texas was found to be more related to Household SES than Neighborhood SES; the relationship was strongest in San Antonio region. These findings may suggest the presence of obesogenic environment in the low SES school districts in these regions. Further studies to examine the particular nature of the obesogenic environment in these school districts are needed in order to support the development of regionalized policy and practice that can be more effective in addressing locale specifics. 相似文献

基于2019年广州18个社区1 470份问卷数据,通过构建结构方程模型探究不同尺度步行环境（包括步行适宜性和其他与步行相关的建成环境要素）对居民肥胖的影响机理。研究发现：居民出行态度与偏好会影响通勤行为,但对居民肥胖没有显著的直接影响。在考虑了居民社会经济属性和出行态度偏好后,居住地步行环境对居民身体质量指数（body mass index, BMI）具有显著的负向总体效应。步行环境对居民BMI的影响具有尺度效应,社区尺度的步行适宜性影响最为显著。不同尺度的绿度、路网密度、地铁站密度和与城市中心的距离等其他与步行相关的建成环境均对居民BMI有不同程度的影响。 相似文献

目的:探讨男性无症状脑梗死(SBI)与腹型肥胖及血生化指标间的相关性。方法:选取开滦集团高管健康查体男性职工645例,采用病例对照研究方法,以腰围≥90cm作为腹型肥胖诊断标准,将其分为腹型肥胖组474例和腰围正常组171例。依据头颅CT诊断为SBI170例,并测定血糖、血脂等血生化指标,收集临床资料。分析男性SBI与腹型肥胖者及血生化指标间的关系。结果:与非SBI组比较,SBI组年龄、高血压病史、糖尿病史、腹型肥胖例数、收缩压、腰围、血糖、低密度脂蛋白胆固醇均高于非SBI组;腹型肥胖组饮酒例数、高血压病史、SBI、体质量指数、血糖、甘油三酯高于腰围正常组(P<0.01,P<0.05),腹型肥胖组年龄、高密度脂蛋白胆固醇低于腰围正常组(P<0.01)。以SBI为因变量的多元逐步回归分析显示,依次筛选出腹型肥胖、收缩压(P<0.01,P<0.05)与其相关。结论:腹型肥胖、收缩压增高可能是SBI患者的独立危险因素。 相似文献
