Walking Exercise on Memory, Subjective Cognitive Complaint, and Brain-derived Neurotrophic Factor for Hypertension

National Taiwan University Hospital66 enrolled

Overview

The purpose of this study is to determine the effect of 6-month aerobic walking program on memory, subjective cognitive complaints, and brain-derived neurotrophic factor for older hypertensive women. Participants will be randomly assigned to the experimental group and the control group. The intervention group will last for 24 weeks. The outcome measurements included memory, subjective cognitive complaints, and brain-derived neurotrophic factor.

The purpose of this study is to explore an aerobic walking program on memory, subjective cognitive complaints, and brain-derived neurotrophic factor. In quantitative study with experimental design, qualified subjects will be randomly assigned to experimental or control group. Experimental subjects will perform six-month aerobic walking program and control group receive routine care. The outcome measurements included memory, subjective cognitive complaints, and brain-derived neurotrophic factor. Data will be collected at baseline, the end of the six-month intervention. Data will be analyzed using Generalized Estimation Equation evaluate the effect of the intervention program.

Interventions

Aerobic exerciseBEHAVIORAL

The intervention was 24 weeks walking exercise program. Participants exercised frequency at 5 sessions a week for 30 minutes per section with moderate-intensity and wearable device assisted. Each session consisted of a 5 minutes warm-up, moderate-intensity walking exercises and 5 minutes cool-down. The program included individualized education, telephone and social media counselling, and booklet guidance

control groupBEHAVIORAL

control group received routine care and a manual on healthy living

Outcomes

Primary Outcomes

Memory Function

The Hopkins Verbal Learning Test was administered to measure verbal learning and memory. The score is a sum of correct responses in each of three learning trial (encoding) (possible score 0 to 36 for summed recall of trials) and a delayed recall trial (possible score 0 to 12). Higher scores mean a better memory.

Time frame: outcome measure at 24th week

Secondary Outcomes

Brain-derived Neurotrophic Factor

Blood sample will be collected. Plasma concentrate of Brain-derived neurotrophic factor will be analyzed by enzyme-linked immunosorbent assay

Time frame: outcome measure at 24th week

Subjective Cognitive Complaints

Cognitive Failures Questionnaire will be used to assess subjective cognitive impairment. Each item is rated from 0 to 4 with the total score calculated as the sum of all items ranging from 0 to 100 with higher scores indicating higher levels of cognitive failures.

Time frame: outcome measure at 24th week
