INTRODUCTION Physical activity may protect against overweight and obesity among preschoolers, and the policies and characteristics of group child care centers influence the physical activity levels of children who attend them. We examined whether children in New York City group child care centers that are compliant with the city's regulations on child physical activity engage in more activity t...

Cities continuously evolve and dynamically organize themselves in unbalanced ways by means of complex processes. Efforts to minimize or solve the problems resulting from spatial inequalities tend fail when relying on traditional public policies. This work is committed analyzing context for implementing policies their impacts periphery São Paulo, Brazil. Paulo a city characterized territorial so...

BACKGROUND Understanding the social environmental around obesity has been limited by available data. One promising approach used to bridge similar gaps elsewhere is to use passively generated digital data. PURPOSE This article explores the relationship between online social environment via web-based social networks and population obesity prevalence. METHODS We performed a cross-sectional st...

PURPOSE To analyze the spatial distribution of the prevalence of anti-toxoplasma gondii antibodies in pregnant women from a Brazilian Northeast city, and to correlate such prevalence with average maternal age and place of residence. METHODS A descriptive, analytical and ecological study was conducted from January 1st to December 31st 2012. Data were obtained retrospectively from the Medical S...

The purpose of this note is to state a collection of results, all related to questions of uniqueness of smooth neighborhoods of finite complexes as imbedded (nicely) in differentiable manifolds. The reported results will appear in subsequent papers, the first of which is [l ]. The approach taken is always via the theory of simple homotopy types (due to J. H. C. Whitehead), and the main theorem ...

According to several researches sustainable development is based on three different dimensions of sustainability social and economical dimensions and ecological or environmental sustainability. These dimensions are recognized as basic elements of sustainable development. This research tries to evaluate social sustainability at some neighborhoods in Karaj. Considering the fact that urban neighbo...

Understanding the role of the built environment on physical activity behavior among older adults is an important public health goal, but evaluating these relationships remains complicated due to the difficulty of measuring specific attributes of the environment. As a result, there is conflicting evidence regarding the association between perceived and objectively measured walkability and physic...
