Social and Neighborhood Predictors of Obesity in Belo Horizonte

描述（由申请人提供）：肥胖已成为拉丁美洲，特别是巴西的一个主要和日益严重的公共卫生问题。社会和物理环境被认为是肥胖的主要决定因素，但在发展中国家，它们对肥胖的影响很少被研究。本项目将在米纳斯吉拉斯的联邦大学和密歇根大学的社会流行病学和人口健康中心之间建立合作关系，以调查巴西大城市贝洛奥里藏特的社会经济和邻里因素在形成肥胖分布以及饮食和体育活动相关行为中的作用。使用贝洛奥里藏特的一项大型人口调查的数据，我们将（1）检查肥胖，饮食和身体活动的社会经济预测因素（2）测试和检查仪器的测量特性，以测量在大型拉丁美洲背景下可能与心血管风险相关的社区物理和社会环境;（3）使用这些工具来检查邻里环境和肥胖之间的联系，饮食和体力活动（4）调查这些社区因素对贝洛奥里藏特心血管危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。公共卫生相关性：肥胖已成为拉丁美洲的主要健康问题。虽然社会和物理环境（包括人们居住的社区特征）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，研究巴西一个大城市肥胖的社会和邻里决定因素。

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.
