Abstract

Background: The presence of risk factors for type 2 diabetes and cardiovascular disease, or the conditions themselves, contributes to lower health-related quality of life (HRQoL) among adults. Although community-based lifestyle intervention programs have been shown to be effective for improving risk factors for these diseases, the impact of these interventions on HRQoL has rarely been described. Purpose: To examine changes in HRQoL following participation in the Group Lifestyle Balance program, a community translation of the Diabetes Prevention Program lifestyle intervention for adults with prediabetes and/or the metabolic syndrome. Methods: Participants enrolled in the 12-month, 22-session intervention program (N = 223) completed the EuroQol Health Questionnaire (EQ-5D-3L) at baseline, 6, and 12 months. Linear mixed-effects regression models determined change in EQ-5D-visual analog scale (VAS) and Index scores post-intervention. Results: Mean EQ-5D-VAS was improved by +7.38 (SE = 1.03) at 6 months and by +6.73 (SE = 1.06) at 12 months post-intervention (both; p < 0.0001). Mean changes in EQ-5D index values were +0.00 (SE = 0.01; NS) and +0.01 (SE = 0.01; p < 0.05), respectively. Adjusted for age, baseline score, and achieving intervention goals, mean change in EQ-5D-VAS was +11.83 (SE = 1.61) at 6 months and +11.23 (SE = 1.54) at 12 months (both; p < 0.0001). Adjusted mean change in EQ-5D index value was +0.04 (SE = 0.01) at 6 months and +0.05 (SE = 0.01) at 12 months (both; p < 0.01). Conclusion: Participation in a community lifestyle intervention program resulted in improved HRQoL among adults with prediabetes and/or the metabolic syndrome. These benefits to HRQoL, together with improved clinical and behavioral outcomes, should increase the appeal of such programs for improving health.
