The objective of this study is to compare the effect of two strategies to increase MVPA in adolescents with intellectual and developmental disabilities (IDD): a single level intervention delivered to the adolescent only, and a multi-level intervention delivered to both the adolescent and a parent .
We will study adolescents with mild to moderate IDD. Each participant will have 1 designated parent who supports the participant during the physical activity (PA) intervention and in the adolescent and parent arm does the physical activity with the participant. Approximately 29 participants/yr. over 4 yrs. will be randomized in a 1:1 allocation to a remote group-based program of MVPA delivered to the adolescent (AO) or a multi-level intervention delivered to both the adolescent and a parent (A+P). Both interventions will be 12 mos. (6 mos. active intervention, 6 mos. maintenance intervention) with a 6 mos. no-contact follow-up targeted to increase MVPA to the recommended 60 min/d. Both intervention will include real-time MVPA sessions delivered to groups of 5-7 adolescents in their homes using video conferencing software (ZoomTM) with homework assignments designed to increase MVPA on the non-group session days. Parents of adolescents in the A+P group will be asked to participate in the group video MVPA sessions and homework activity, and to attend sessions (0-6 mos. 2 session/mo.; 7-12 mos. 1 session/mo.) with their adolescent and the health coach designed to educate/support parents regarding the role of MVPA in health and function and strategies for increasing MVPA and decreasing sedentary time in both their adolescent and themselves. All participants will monitor their daily PA using a Fitbit wireless activity tracker.

Change in Adolescent Physical Activity From Baseline to 6 Months
Moderate to vigorous physical activity was assessed using an ActiGraph accelerometer worn during waking hours for 7 consecutive days, with the exception of bathing, and swimming. Data were considered valid if they wore the accelerometer for at least 8 hours on 3 days, including 1 weekend day.
Time frame: Change from baseline to 6 months
Change in Adolescent Moderate to Vigorous Physical Activity From Baseline to 18 Months
Moderate to vigorous physical activity was assessed using an ActiGraph accelerometer worn during waking hours for 7 consecutive days, with the exception of bathing, and swimming. Data were considered valid if they wore the accelerometer for at least 8 hours on 3 days, including 1 weekend day.
Time frame: Change from baseline to 18 months
Change in Parent Physical Activity
Moderate to Vigorous Physical Activity in parents of participants will be assessed at baseline, 3, 6, 12, and 18 months using an ActiGraph accelerometer over 7 days
Time frame: Change from baseline to 18 months
Change in Sedentary Time
Sedentary Time in adolescents with IDD will be assessed at baseline, 3, 6, 12, and 18 months, using an ActiGraph accelerometer over 7 days.
Time frame: Change from baseline to 18 months
Change in Parent Sedentary Time
Sedentary Time in parents of participants will be assessed at baseline, 3, 6, 12, and 18 months, using an ActiGraph accelerometer over 7 days.
Time frame: Change from baseline to 18 months
Change in Cardiovascular Fitness
Cardiovascular fitness will be assessed by treadmill at baseline, 3, 6, 12, and 18 months
