What this Trial Is About

Background: Heart disease is a leading cause of death in the United States. Healthy diet and exercise improve heart health. Some features of where a person lives can lead to stress and decrease chances for exercise. Researchers want to see how these factors may increase the risk of heart disease in women. Objective: To see if there are differences in stress levels between women who live in different parts of Washington, DC. Also, to see how these women use their neighborhoods for exercise. Eligibility: Healthy white or black females ages 19-45 who live in Washington, DC, who have access to a smartphone Design: Participants may stay at the NIH Clinical Center overnight for a 2-day visit. Visit 1 will include: Physical exam Blood tests Electrocardiogram: Electrodes on the participant s skin will measure heart activity. PET/CT scan: Participants will get an injection. They will lie in a machine that takes pictures of the body. Surveys Body size measurements Nutrition consultation Blood vessel tests: This is measured with blood pressure cuffs, a device placed on the participant s fingertip, and a probe placed on the participant s neck. Resting Energy Expenditure: Participants will breathe under a clear hood for 45 minutes. Participants will be followed for about 2 weeks. They will wear a device on the wrist and carry a GPS device. Through a mobile app, they will answer short daily surveys on stress and exercise. Visit 2- Device return Nutritional consultation
