Built environment neighborhood characteristics are difficult to measure and assess on a large scale. Consequently, there is a lack of sufficient data that can help us investigate neighborhood characteristics as structural determinants of health on a national level. The objective of this study is to utilize publicly available Google Street View images as a data source for characterizing built environments and to examine the influence of built environments on chronic diseases and health behaviors in the United States. Data were collected by processing 164 million Google Street View images from November 2019 across the United States. Convolutional Neural Networks, a class of multi-layer deep neural networks, were used to extract features of the built environment. Validation analyses found accuracies of 82% or higher across neighborhood characteristics. In regression analyses controlling for census tract sociodemographics, we find that single-lane roads (an indicator of lower urban development) were linked with chronic conditions and worse mental health. Walkability and urbanicity indicators such as crosswalks, sidewalks, and two or more cars were associated with better health, including reduction in depression, obesity, high blood pressure, and high cholesterol. Street signs and streetlights were also found to be associated with decreased chronic conditions. Chain link fence (physical disorder indicator) was generally associated with poorer mental health. Living in neighborhoods with a built environment that supports social interaction and physical activity can lead to positive health outcomes. Computer vision models using manually annotated Google Street View images as a training dataset were able to accurately identify neighborhood built environment characteristics. These methods increases the feasibility, scale, and efficiency of neighborhood studies on health.
This roundtable grew out of conversations between filmmaker Rea Tajiri, programmer Abby Sun, and scholar Vince Schleitwiler about a misunderstood chapter in the history of Asian American film and media: New York City in the eighties, a vibrant capital of Asian American filmmaking with a distinctively experimental edge. To tell this story, Rea Tajiri contacted her artist contemporaries Shu Lea Cheang and Roddy Bogawa as well as writer and critic Daryl Chin. Daryl had been a fixture in New York City art circles since the sixties, his presence central to Asian American film from the beginning. The scope of this discussion extends loosely from the mid-seventies through the late nineties, with Tajiri, Abby Sun, and Vince Schleitwiler initiating topics, compiling responses, and finalizing its form as a collage-style conversation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
