摘要:We examined geographic and social factors associated with participation in the Chronic Disease Self-Management Program (CDSMP) and the Diabetes Self-Management Program (DSMP) implemented at 144 sites in Illinois. Programs were delivered by trained facilitators, once per week, during 6 weeks to 1,638 participants aged 50 or older. Of the 1,638 participants, we included in our analysis 1,295 participants with complete geographic information and baseline data on demographic characteristics, health history, and health behaviors. We assessed the following program data: program type (CDSMP or DSMP), workshop location, class size, and number of sessions attended by participants. We geocoded each participant's home address, classified the home address as rural or urban, and calculated the distance traveled from the home address to a workshop. We used linear and logistic regression analyses to examine the associations between participant and program factors with number of sessions attended and odds of program completion by whether participants lived in an urban or rural county. Average program attendance was 4.2 sessions; 71.1% (1,106 of 1,556) completed 4 or more sessions. Most participants enrolled in CDSMP (59.6% [954 of 1,600]), but DSMP had greater completion rates. Less than 7% (85 of 1,295) of our sample lived in a rural county; these participants had better completion rates than those living in urban counties (89.4% [76 of 85] vs 75.6% [890 of 1,178]). Traveling shorter distances to attend a workshop was significantly associated with better attendance and program completion rates among urban but not rural participants. The number of sessions attended was significantly higher when class size exceeded 16 participants. Not having a high school diploma was significantly associated with lower levels of attendance and program completion. Participation in CDSMP and DSMP was associated with distance traveled, program type, class size, and education. Increasing participation in self-management programs is critical to ensure participants' goals are met.
