Lifestyle interventions promote increased physical activity (PA) and weight loss; however, relapse to sedentary behavior and weight regain are common.
We analyzed baseline and 24-month data from participants in the Slow the Adverse Vascular Effects (SAVE) study. SAVE included an 18-month behavioral intervention. At 24 months, participants completed a survey about lifestyle strategies used in past 6 months. PA levels were assessed with the Modifiable Activity Questionnaire. We compared change in weight, BMI, and PA from baseline to 24 months by use of strategies vs. no use.
214 participants (61%) completed 24-month visit. 74% were female and 86% were white. At 24 months, 65% used self-monitoring, 67% group/commercial support, 94% other behavioral skills, and 27% used professional support within past 6 months. At 24 months, participants who used self-monitoring (5.2 vs. –0.8 MET-hr/wk; P = .001) and group/commercial support (4.3 vs. 0 MET-hrs/wk; P = .01) had greater PA increases compared with those who did not use strategies. Participants who used other behavioral strategies had a significantly greater percent decrease in weight than those who did not.
Of the lifestyle strategies used following intervention, self-monitoring and group/commercial support may be particularly important in longer-term PA levels.
