Environmental Factors and Diabetes Development in Latinos (SOLAir)

The purpose of SOLAir is to understand how environmental factors, including air pollution and the built and natural environment, are related to the risk of diabetes  

Para información en Español

• The SOLAir study involves a device belt worn around your waist for 8 days. These devices measure your physical activity patterns. 
• One of the devices uses GPS. The purpose of the GPS is simply to allow us to see how much physical activity participants engage in in various types of settings (such as parks). We are not interested in the specific places you visit, and we will keep the data confidential.
• None of the devices transmit data, they only store data. We will access those data when you return the devices at the end of the 8 days.
• You will be responsible for returning all devices, the log, and the charging cord and adapter at the end of the 8 days. 
• There are no direct benefits to you for participating in this study except that you will receive an incentive. You will be helping contribute to research that aims to support disease prevention efforts in Hispanics/Latinos. 
• Participation in this study is completely voluntary and you can stop participating at any time. 
• Your enrollment in this study will not impact your standing with the HCHS/SOL study. 

Instructions 

Overview 

• You are being asked to wear one device belt that contains 2 devices over the next 8 days. 
• Each of the devices you will be wearing measures your physical activity throughout the day but in a slightly different way. We are studying these different devices to see what aspects of daily activity relate to health.
• The devices should be worn at the same time (together, not one at a time).
• To get the best scientific data, we ask that you please engage in your usual activities and do not alter your daily routine because of this study. 

Device belt

• The belt should be worn during all waking hours for 8 days (not overnight). 
• The black device in the pouch should be charged every night. 
• Do not wear the belt in the shower or get it wet. 

How to wear the devices:

• Belt devices:
  • The belt should be snug but not too tight. You may adjust the straps if needed.
  • The belt can be worn as seen in image or it can be worn under clothing. 
  • The red box on the belt should sit on your right hip (red on right). 
  • Take belt off when you go to bed, charge black device in the pouch using the provided charger, and put the belt back on in morning when you get out of bed.
