Abstract

We examined the effects of active learning education on arterial stiffness and physical activity of community-dwelling older adults with low health literacy. This study is a secondary analysis of randomized controlled trial of 60 participants aged 65 and older with low health literacy. The intervention group (n=30) participated in a weekly 90-minute active learning program session for 24 weeks, which addressed health promotion in older age. The control group (n=30) attended a 90-minute health education class in a didactic manner. The outcomes were measured at baseline and in week 24. The degree of arterial stiffness was assessed based on the cardio-ankle vascular index (CAVI) using the VS-1500 device (Fukuda Denshi Co., Ltd., Tokyo, Japan). The shortened version of the self-reported International Physical Activity Questionnaire was used to assess the amount of total physical activity determined by the metabolic equivalent hours per week. We used analysis by intention-to-treat, with multiple imputation for missing data. Seven participants (11.7%) dropped out prior to the post-intervention assessment. The multiple imputation analysis revealed that the intervention group showed significant improvement in CAVI [between-groups difference (95% confidence interval)=-0.78 (-1.25 to -0.31), Cohen's d=0.82] and physical activity [32.5 (0.3 to 64.7), Cohen's d=0.57] as compared with the control group. The sensitivity analysis for the complete cases showed similar results. Active learning health education may be effective in improving arterial stiffness and physical activity in older adults with low health literacy.
