Effects of Integrated Cardiovascular Health Education Program on Older Adults at Risk of ASCVD

The Effects of an Integrated Exercise and Cardiovascular Health Education Programme on Community-dwelling Older Adults at Risk of Atherosclerotic Cardiovascular Diseases: A Randomised Controlled Trial

Despite older adults being exposed to an increased risk of atherosclerotic cardiovascular disease (ASCVD), they are generally underrepresented in cardiovascular prevention programmes. The aim of this study is to examine the effects of an integrated exercise and cardiovascular health education programme (HE programme) on community-dwelling older adults at risk of ASCVD.

Study Overview

• Status: Not yet recruiting
• Conditions: Cardiovascular Diseases; Health Education; Healthy Lifestyle
• Intervention / Treatment: Behavioral: HE programme; Behavioral: Usual care

Detailed Description

The study is a two-arm randomized controlled trial. (1) The control group will mainly receive a basic lifestyle modification talk, a lecture video and governmental education leaflets. (2) The experimental group will receive an integrated exercise and health education programme (HE programme) based on self-efficacy theory. Physical activity level, exercise self-efficacy and ASCVD risk profile including blood pressure, cardiac endurance, fasting blood glucose, fasting blood lipids, and anthropometric outcomes will be investigated via physiological assessments, medical history-taking or questionnaires at baseline, Week 12, Week 24 and Week 36.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Physical activity level (total score) at Week 24	The physical activity level will be measured by the Chinese Version of Physical Activity Scale for the Elderly (PASE-C). The total score (from zero to 400 or above) is quantified based on frequency values and weights for these activities. The higher the score, the higher the level of physical activity.	At Week 24
Physical activity level (classification of physical activity level) at Week 24	The physical activity level will be measured by the Chinese version of International Physical Activity Questionnaire-short form (IPAQ-C-short form). Participants are classified into "inactive", "minimally active" or "health enhancing physical activity (HEPA) active" based on their physical activity levels.	At Week 24
