Abstract
OBJECTIVES: To evaluate the effects of two digital health interventions on anxiety symptoms, depressive symptoms, and health-related quality of life (HRQOL) in older adults at cardiovascular risk. METHODS: In this randomized pilot trial, older adults (n = 54; mean age 65.6 ± 5.8 years; 60% women; 66% Hispanic) with intermediate or high cardiovascular risk were assigned to Get FIT (n = 24) or Get FIT+ (n = 30). Get FIT included one counseling session, an activity tracker, and a nutrition app. Get FIT+ included these components, plus weekly personalized motivational text messages. Outcomes were assessed at baseline, three months, and six months. RESULTS: At 3 months, both groups showed small reductions in anxiety and slight improvements in HRQOL, with no significant differences between the groups. Depressive symptoms remained stable. By six months, anxiety trajectories differed: reductions were maintained in Get FIT+ but returned to baseline in Get FIT (p < .001). Both groups increased physical activity and reduced caloric intake. Weight loss occurred in both groups but was greater in Get FIT+ (all p < .001). CONCLUSIONS: The improved intervention in this initial study was associated with sustained reductions in anxiety and with greater weight loss. CLINICAL IMPLICATIONS: Customized digital programs support older adults at risk of heart issues by encouraging healthier habits and enhancing mental health.
