The study aims to determine if use of physical activity trackers coupled with provider feedback will increase awareness of young adults of their physical fitness and improve blood pressure levels. The goal of this pilot study is feasibility, with a secondary goal of examining potential effect sizes for planning purposes for a larger randomized controlled trial.
Increasing physical activity levels may improve cardiovascular health and BP levels in young individuals, especially if such strategies promote healthy lifestyles. Physical activity is currently recommended for adults CV health, but physical activity levels are known to be low in populations with diabetes or chronic kidney disease. One prior study of the use of pedometers (not associated with wireless technology or provider feedback) in children with CKD did not significantly improve physical activity levels. Supervised walking appeared to provide some benefit in individuals with type II diabetes, but overall compliance was poor. Interview of adolescents and young adults with chronic illnesses has shown preference for the use of electronic devices and online tools for disease management.Thus, use of sophisticated electronic devices such as FitBits© (wireless pedometers worn on the wrist that sync with cell phones) may improve disease control by engaging young patients in self-monitoring of their own health and lifestyle behaviors. This pilot study aims to determine if use of FitBits© coupled with provider feedback will increase awareness of young adults of their physical fitness and improve blood pressure levels.

Change in Mean Office Systolic BP
Change in mean systolic BP is modeled using all blood pressure data points collected between baseline and month 12 to provide an average change over time, accounting for repeated values from patients using a mixed linear regression approach.
Time frame: Between baseline and month 12
Change in Mean Office Systolic BP
Change in mean systolic BP using blood pressure data points collected between baseline and month 6 to provide an average change over time
Time frame: Between baseline and month 6
Number of Participants Retained
Rate of study participant retention
Time frame: Months 0-12
Change in Weight (Z-score)
Weights were measured in clinic using a standardized scale. Z score of 0 represents the population mean. A z-score of +1.96 represents the 95th percentile of weight and -1.96 represents the 5th percentile of weight. Change in weight (z-score) is modeled using all weight data points collected between baseline and month 12 to provide an average change over time accounting for repeated values from patients using a mixed linear regression approach.
Time frame: Months 0-12
