This study is being done to understand how a physical activity walking intervention affects metabolic parameters (i.e., blood sugar, cholesterol, certain body measurements) in people with and without HIV. This study involves a physical activity intervention where participants will progressively increase activity as tolerated over a six month period.

This study is being done to understand how a physical activity walking intervention affects metabolic parameters (i.e., blood sugar, cholesterol, certain body measurements) in people with and without HIV. This study involves a physical activity intervention where participants will progressively increase the total number of daily steps to approximately 10,000 steps/day as tolerated. We will monitor participant steps and physical activity using a physical activity monitor. The study will consist of 5 in-person study visits where participants will complete body measurements, laboratory testing (for metabolic parameters e.g. blood sugar and cholesterol), and a questionnaire.
