^a Attendance information for each participant in the program was provided by facilitators of the CDSMP and DSMP programs. The number of attended sessions ranged from 1 to 6. The overall model explained 4.8% of the variance in the number of sessions attended (R = 0.24; Adjusted R ² = 0.048; ΔR ² = 0.004; P = .049).

^b Per US guidelines (≥150 min per week [18]).

^c Urban and rural classifications were determined by using participants’ home address and criteria from the US Census Bureau’s Office of Management and Budget (13,14).
