Background Memory loss in older age affects women more than men and cardiovascular disease is a leading risk factor. Physical activity can improve memory in healthy older adults; however, few physical activity interventions have targeted women with cardiovascular disease, and none utilized lifestyle approaches. Purpose The purpose of this study was to examine feasibility, acceptability, and preliminary effects of a 24-week lifestyle physical activity intervention (physical activity prescription, five group meetings, and nine motivational interviewing calls). Methods A sequential mixed-methods approach was used. Participants were 18 sedentary women ≥65 years with cardiovascular disease and without cognitive impairment recruited in August 2017. Feasibility, acceptability, self-reported health, accelerometer-assessed physical activity, and neurocognitive memory tests were measured using a pre-post test design. Two post-intervention focus groups ( n = 8) were conducted in June 2018. Concept analysis was used to identify barriers/motivators of intervention participation. Results Meeting attendance was >72% and retention was 94%. Participants rated the program with high satisfaction. There were significant improvements at 24 weeks in self-rated physical health, objective daily steps, and estimated cardiorespiratory fitness ( d = .30–.64). Focus group themes generated recommendations for modifying the intervention. Conclusion Findings support adapting the intervention further for women with cardiovascular disease and testing it in an efficacy trial. |
