Ecological Momentary Assessment of Neighborhood Conditions and Cardiovascular Health Behaviors in New York City Public Housing Residents
Funded By: Aetna Foundation/Academy Health

Ecological momentary assessment (EMA) methods focus on what is happening in the current moment and therefore are effective in contextualizing the moments in which health behaviors occur. The purpose of this pilot study is a) to evaluate the acceptability of collecting data via EMA methods qualitatively in a sample (n = 60) of New York City public housing residents and b) to evaluate the feasibility of collecting data on neighborhood conditions and cardiovascular health behaviors (e.g. physical activity, diet and nutrition, smoking) via text messaging among a small sample (n = 30) of New York City public housing residents.

Determining Accuracy of GPS Devices: A Multi-Device GPS Study
Funded By: NYU School of Medicine

Different global positioning system (GPS) devices are used by various researchers to collect real-time data from participants for a variety of purposes, especially in the field of spatial epidemiology. However, very little is known about the accuracy of these devices. We wish to determine the accuracy and efficiency of two commonly used devices by comparing positional differences between the devices. The overall aim of the project is to understand the reliability and validity of using real-time geospatial in a sample of NYU School of Medicine staff members (n = 15) technologies to establish protocols that will improve research outcomes and methods.

Activity Space Neighborhoods, Drug Use, and HIV Among Black Men Who Have Sex with Men (MSM) in the Jackson, Mississippi Metropolitan Statistical Area (MSA)
Funded By: NYU Center for Drug Use and HIV Research

Despite decades of behavioral research examining a broad range of individual-level risk factors, stark racial disparities in drug use and HIV prevalence and incidence persist among men who have sex with men (MSM), and these disparities are greatest in the Deep South. This study seeks to utilize real-time geospatial methods to investigate relationships between global positioning system (GPS)-defined activity space neighborhoods, drug use and HIV risk among Black MSM in the Jackson, Mississippi metropolitan statistical area (MSA).

New York City Physical Activity and Transit (PAT) Survey: GPS Sub-Study
Funded By: NYU School of Medicine

The Physical Activity and Transit (PAT) Survey aimed to assess the level and conditions of physical activity of New Yorkers. A sample (n = 3,806) of adults in New York City completed a comprehensive survey of self-reported physical activity, neighborhood characteristics, and patterns of physical activity. A sub-sample (n = 679) additionally completed a protocol including objective measures of physical activity, including accelerometers and GPS devices. We are collaborating the New York City Department of Health and Mental Hygiene to conduct spatial analyses of the GPS data collected.

Neighborhood Walkability and Cardiometabolic Outcomes in the Paris Metropolitan Area
Funded By: NYU College of Global Public Health

The goal of the proposed project is to use novel measures of neighborhood walkability to understand how neighborhood walkability outcomes (especially obesity and hypertension) among a unique population-based sample of adults in the Paris (France) metropolitan area. Data from this project come from the Residential Environment and Coronary Heart Disease (RECORD) Cohort Study, led by Dr. Basile Chaix.

Understanding Obesity Among Public Housing Residents in New York City: A Community-Based Geospatial Approach
Funded By: NYU Clinical and Translational Science Institute

The overall aim of this community-based geospatial project is to test the use of novel real-time geospatial technologies (particularly global positioning systems [GPS] tracking) for neighborhood health research in a sample (n = 120) of low-income and public housing residents to examine the link between neighborhood environmental conditions and cardio-metabolic outcomes (e.g. obesity and hypertension outcomes).

Feasibility Assessment of Using Real-Time Geospatial Methods to Explore Social and Spatial Contexts of Substance Use and HIV Risk in Young Men Who Have Sex with Men
Funded By: NYU Center for Drug Use and HIV Research

The purpose of this pilot study is to use global positioning system (GPS) technology as a means of exploring associations between multiple neighborhoods with substance use and risky sexual behaviors among a racially and ethnically diverse sample (n = 75) of young men who have sex with men (YMSM).

Health App Use Among Verizon Users in the United States
Funded By: The Verizon Foundation

The proposed study will fill this gap in knowledge about demographics of health app users and reasons for health app use by examining these factors in a sample Verizon users in the United States. More specifically, the aims of the proposed project are to survey US-based Verizon users on: demographic characteristics, reasons for health app use, frequency of health app use, perceived effectiveness of health apps used and reasons for stopping use. This innovative project has substantial implications for marketing and improving smart phone-based health apps.
