Summary

We are conducting a research study to learn about how individuals living in Washington, DC perceive and experience temperature. Participation in this study will include: 2 remote visits over the phone and/or computer (these will each last about1.5 to 2 hours) * During the remote visits, you will be asked to respond to a series of surveys, so that we can learn about your life, behaviors, and health 2 weeks of data collection where you will be asked to: * Wear monitoring devices * These will collect information on your location and physical activity * We will ask you to wear the monitors on a belt around your waist all day every day during these 2 weeks of data collection. * All of the monitors will be sent to you in the mail. * Leave a temperature tracker near where you sleep to measure the temperature of your environment. * Use a phone app * We will also send you questions through the phone app that will ask about your stress level, sleep duration, sleep quality, and how you feel about the current temperature. Risks of participating in this study are minimal. They include the inconvenience of wearing the monitors and the possibility of a breach of your confidentiality. We are collecting personal information about you and the location monitor will collect information about where you spend your time. We will take every precaution in order to safeguard the data that you provide, including limiting who has access to it, storing it safely, and removing the capacity to identify you individually, as much as possible. You will receive no immediate benefits from participating in this study. We hope what we learn will help us to develop policies and programs to help keep urban populations safe during increasingly warm summer temperatures. You are eligible for this study if you are 18 years of age or older, live in Washington, DC, can read and write in English, and have access to a smartphone that you can use for the 2 week data collection period....

Detailed description

Study Description: This pilot study will test measures for cardiometabolic behaviors and outcomes (e.g., physical activity, sedentary behavior, stress, sleep quality, sleep quantity) and individually experienced temperature with intensive longitudinal data collected via wearable devices and smart phone-based ecological momentary assessment. The primary hypothesis is that there are associations between individually experienced temperature and the identified behaviors and outcomes. Objectives: Primary: To explore within and between-person associations between individually experienced temperature and cardiometabolic risk behaviors and outcomes. Secondary: Aim 1: Explore disparities in individually experienced temperature based on race, ethnicity, socioeconomic factors, sex, and age. Aim 2: Explore multilevel determinants of individually experienced temperature: neighborhood environment (residential and activity space), home, workplace, and preferences Endpoints: Primary: * Physical Activity * Sedentary behavior * Stress/mental well-being * Sleep quantity * Sleep quality Secondary: * Daily mean individually experienced temperature * Daily maximum individually experienced temperature * Daily degree minutes above threshold * Longest daily exposure period
