Physical Activity and Glycemic Control in Adolescents

3 de julho de 2020 atualizado por: Yale University
The purpose of this pilot study is to evaluate the initial efficacy of a reinforcement intervention to enhance physical activity levels in sedentary adolescents and young adults with type 1 diabetes (T1D). The intervention will reinforce patients for meeting physical activity goals, with escalating reinforcers provided when patients achieve continuous weeks of meeting goals. A 12-week trial will be conducted in which 60 patients will be randomized to: (1) standard care or (2) standard care plus reinforcement.

Descrição detalhada

Specific aims are:

  1. To determine if the reinforcement intervention increases walking. The proportion of days on which participants meet walking goals will be assessed via Fitbit, a commercially available activity monitor, as well as continuous weeks on which goals are met. The hypothesis is that patients assigned to the reinforcement intervention will meet walking goals on a higher proportion of days and have longer durations of meeting walking goals than patients assigned to standard care.
  2. To assess if the intervention reduces A1c. Patients randomized to the reinforcement intervention are expected to have greater decreases in A1c than patients in usual care.

In addition to the primary aims, secondary outcomes will also be evaluated. The intervention is expected to enhance subjective and objective indices of fitness, increase quality of life, improve indices of diabetes management and decrease depression symptoms. Predictors of response to treatment will also be evaluated.

Results from this pilot study will be instrumental for guiding a subsequent, larger and longer term randomized study for evaluating reinforcement interventions for improving outcomes of youth and young adults with T1D.

Intervenção / Tratamento
Experimental: Reinforcement treatment
Participants in this condition will receive reinforcement for meeting targeted physical activity goals. These subjects will receive the same treatment as standard treatment group, including incentives for uploading/synching and discussions of ADA recommendations of managing diabetes in the context of physical activity. The only difference between conditions is that participants in this condition will earn tangible reinforcement for walking the target number of steps per day (6,000 per day in week 1, 8,000 per day in week 2 and 10,000 per day in weeks 3-12). At each upload, participants will earn incentives for each day on which they met the step goals. In addition, for each 7-day period in which they meet goals on at least 5 days, they will earn bonuses.

Outro: Standard of Care
Participants in the standard of care group will be told to wear Fitbit daily for 12 weeks. They will be instructed to upload or synch it >2x/week, on set days, e.g., Mon and Thurs, for the next 6 weeks and then weekly in the last 6 weeks. They will receive incentives for each upload, plus a bonus for each week in which data are registered for all 7 days in the week as scheduled. They will be encouraged to review Fitbit steps daily and on each upload/synch day. After each upload, research staff will congratulate patients via email or text for days on which they met goals, and encourage meeting goals in the upcoming week.

The HAES is filled out for both a typical weekday and weekend day. Total number of hours per day spent in each of four activity categories (inactive, somewhat inactive, somewhat active, and very active) will be calculated. Total activity (hours per day somewhat active + hours per day very active) also will be calculated. Two total activity scores are calculated - 1 for the weekday and 1 for the weekend day.
