Abstract:

BACKGROUND: In previous efforts, health-related quality of life (HRQoL) improved for individuals at high risk of type 2 diabetes and cardiovascular disease after participation in community-based lifestyle interventions (LI) with a moderate-to-vigorous physical activity (MVPA) movement goal. PURPOSE: It is unknown whether HRQoL improves with LI when the primary movement goal is to reduce sedentary behavior. HRQoL changes were examined among adults with overweight and prediabetes and/or metabolic syndrome randomized to a 12-month Diabetes Prevention Program-based Group Lifestyle Balance (DPP-GLB) community LI work with goals of weight-loss and either increasing MVPA (DPP-GLB) or reducing sedentary time (GLB-SED). METHODS: Study participants (N = 269) completed the Euroqol 5 dimension 3 long (EQ5D-3L index and EuroQol Visual Analog Scale (EQVAS)-visual analog scale) at baseline, and 6 and 12 months. Paired t-tests were used to evaluate pre-to-post-intervention changes by arm. RESULTS: Mean EQVAS improvements for the GLB-SED arm at 6 and 12 months were +5.6 (SE = 1.3; P < .0001) and +4.6 (SE = 1.4; P = .0006), respectively. Similar mean EQVAS improvements were reported for the DPP-GLB arm; +5.9 (SE = 1.2; P < .0001) and +4.9 (SE = 1.2; P = .0001) at 6 and 12 months, respectively. Mean EQ5D index improvements were significant in the GLB-SED arm [6 months: +0.03 (SE = 0.01; P = .004); and 12 months: +0.04 (SE = 0.01; P = .006)], but not in the DPP-GLB arm. CONCLUSIONS: Participation in community LI with a primary movement goal to reduce sedentary behavior improved HRQoL at least as well as traditional LI focused more on MVPA improvement, supporting an alternate intervention strategy for those who can''t or won''t engage in MVPA as the primary movement goal.
