Use of Track Health Function of the MyHealthevet Personal Health Record

The study intervention involved the provision to study participants of targeted instruction and practice on use of two features of the Track Health (TH) function of the VA's patient health record (PHR) known as My HealthyVet (MHV) -- Journals and Vitals + Readings -- as a basis for promoting positive physical activity (PA) and dietary lifestyles. Seven interactive multimedia instructional modules were developed by the study team. These modules demonstrated on a computer screen how to enter PA and diet information into the Journals feature; how to add weight data into the Vitals + Readings feature; how to view these and other measures in tabular and graphical formats over different time frames; and the concept of possible cause-effect links between behavioral lifestyle and physiological outcome data. Participants were directed to enter food intake, PA, and weight information a specified number of times per week over the 3-month study period.
