Social and Neighborhood Predictors of Obesity in Belo Horizonte

描述(申请人提供)：在拉丁美洲，特别是在巴西，肥胖已经成为一个主要的、日益严重的公共卫生问题。社会和自然环境一直被认为是肥胖症的主要决定因素，但它们对发展中国家肥胖症的影响却很少被研究。该项目将建立米纳斯吉拉斯联邦大学和密歇根大学社会流行病学和人口健康中心之间的合作，以调查社会经济和邻里因素在影响巴西大城市贝洛奥里藏特肥胖分布和饮食和体育活动相关行为方面的作用。利用Belo Horizonte一项大规模人口调查的数据，我们将(1)检验肥胖、饮食和体力活动的社会经济预测因素；(2)测试和检查测量工具的测量特性，以测量可能与心血管风险相关的社区物理和社会环境；(3)使用这些工具检查社区环境与肥胖、饮食和体育活动之间的关联；(4)调查这些社区因素对Belo Horizonte心血管风险因素的社会经济模式的贡献。这项研究将主要在巴西贝洛奥里藏特的米纳斯吉拉斯联邦大学医学院与Fernando Proietti和Waleska Caiaffa合作进行，作为NIH的延伸。与公共卫生相关：肥胖已成为拉丁美洲的主要健康问题。尽管社会和自然环境(包括人们居住的社区的特征)被假设为导致肥胖的因素，但这些因素仍然没有得到充分的研究，特别是在拉丁美洲国家。该项目将利用一项大型调查的数据来研究巴西一个大城市肥胖的社会和社区决定因素。

DESCRIPTION (provided by applicant): Obesity has emerged as a major and growing public health problem in Latin America, and specifically in Brazil. Social and physical environments have been hypothesized to be major determinants of obesity but their contribution to obesity in developing countries has been infrequently examined. This project will establish a collaboration between the Federal University of Minas Gerais and the Center for Social Epidemiology and Population Health of the University of Michigan to investigate the role of socioeconomic and neighborhood factors in shaping the distribution of obesity and the related behaviors of diet and physical activity in Belo Horizonte, a large city in Brazil. Using data from a large population-based survey of Belo Horizonte we will (1) examine socioeconomic predictors of obesity, diet, and physical activity (2) test and examine the measurement properties of instruments to measure neighborhood physical and social environments potentially related to cardiovascular risk in the context of a large Latin American; (3) use these instruments to examine associations between neighborhood environments and obesity, diet and physical activity (4) investigate the contribution of these neighborhood factors to the socioeconomic patterning of cardiovascular risk factors in Belo Horizonte. This research will be done primarily at the School of Medicine of the Federal University of Minas Gerais in Belo Horizonte, Brazil in collaboration with Fernando Proietti and Waleska Caiaffa as an extension of NIH. PUBLIC HEALTH RELEVANCE: Obesity has emerged as major health problem in Latin America. Although social and physical environments (including features of the neighborhoods where people live) have been hypothesized to contribute to obesity these factors remain understudied especially in countries of Latin America. This project will utilize data from a large survey to study the social and neighborhood determinants of obesity in a large city of Brazil.
