iSTEP - an mHealth Physical Activity and Diet Intervention for Persons With HIV

Completed · Not applicable

Conditions studied: HIV/AIDS

In brief

HIV is associated with a pattern of neurocognitive deficits, metabolic dysfunction, and an elevated risk for cardiovascular disease (CVD), phenomena that remain untreated despite the use of medications to control the disease. This proposal will examine the effect of a personalized, automated, interactive mobile phone text message intervention (iSTEP) designed to increase moderate physical activity (PA), decrease sedentary behavior (SB), and promote a healthy Mediterranean-style diet (MedDiet) in persons living with HIV (PLWH). The investigators propose that participants who receive the iSTEP intervention will increase the amount of physical activity, improve their diet, show a reduction in risk factors for CVD, and exhibit improved neurocognitive performance.
