Activity space neighborhoods, drug use and HIV among black MSM in the Jackson, MS MSA
Funded by: National Institute of drug abuse

This project 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 men who have sex with men (MSM) in the Jackson, Mississippi metropolitan statistical area (MSA).

 

Neighborhoods, Mobility and HIV among young MSM
Funded by: The National Institute of Mental Health

This project seeks to investigate spatial mobility across neighborhoods as well as relationships between Global Positioning System (GPS)-defined activity space neighborhoods and HIV risk among young men who have sex with men (MSM) in the New York City metropolitan area, through the use of innovative methodological approaches including real-time geospatial methods and geo-located Twitter posts

 

Impact of Neighborhoods and Networks on HIV Prevention and Care Behaviors Among Black MSM in the Deep South
Funded by: The National Center for HIV/AIDS, Viral Hepatitis, STD, and TB Prevention

This project seeks to use real-time geospatial methods to investigate relationships between Global Positioning System (GPS)-defined activity space neighborhoods, social and sexual networks, and HIV prevention and care behaviors cross-sectionally and longitudinally among Black men who have sex with men (MSM) in the Jackson, Mississippi metropolitan statistical area (MSA) followed over a year.

 

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.

Status: Data Analysis

 

Community-Level Norms and Sexual Beliefs, Behaviors and STIs in HIV-Infected Men

Funded By: HIV Prevention Trials Network (HPTN)

The purpose of this study is to better understand cross-sectional and longitudinal associations between community-level norms and sexual beliefs, behaviors and STIs among a sample of HIV-infected men in care in global settings (HPTN 063). The proposed study aims to fill existing gaps in research regarding neighborhood environments and HIV outcomes in men, including among MSM.

Status: Data Analysis

 

Completed Projects

Neighborhood Activity Space, Drugs and HIV Risk Among Black MSM in the Deep South: A Pilot Study
Funded By: NYU Center for Drug Use and HIV Research

The specific aims for the novel research include: 1) To determine the feasibility of obtaining GPS spatial behavior data to define activity space neighborhoods, using an innovative 2-week GPS protocol, among a sample of 25 Black MSM in Jackson, MS. 2) To qualitatively evaluate the meaning of activity space environments and reasons for spatial mobility among a sample of 25 Black MSM in Jackson, MS.

 

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.

 

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.

 

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.
