The effects of a web-based educational intervention on total exercise amount, and self- efficacy for exercise in soon-to-be-aged adults with coronary heart disease (Preprint)
BACKGROUND Coronary heart disease (CHD) is the leading cause of death globally, and e-health educational programmes have proven to be an effective support for patients. Considering the advantages of such programmes, as well as the growing number of soon-to-be aged patients with CHD, a study was conducted. OBJECTIVE It aims to investigate the effectiveness of a home-based interactive e-health educational intervention (eHEI) for patients with CHD in terms of improvements in their total amount of physical exercise, self-efficacy for exercise, and CHD risk factor profile. METHODS A prospective randomized controlled trial (RCT). The study was conducted in two government cardiac clinics in Hong Kong. Using a block randomization method, 441 eligible CHD clients were randomly assigned to either the control or intervention group. All of the participants received standard care, which consisted of regular follow-ups with a doctor and medical prescriptions related to their CHD, while the intervention group received in addition the e-HEI, which consisted of a 20-minute individual educational session on the use of the web link. The web link contains general health information related to CHD and an individual member area with records of health measures and physical exercise data for six months. Data were collected at baseline, and at three-month and six-month intervals at the cardiac clinic. The primary outcome was the total amount of physical exercise, measured by the Godin–Shephard Leisure-Time Physical Activity Questionnaire. The secondary outcomes were total exercise time, self-efficacy for exercise, and CHD risk profile (body weight, blood pressure, lipids profile). The data were analyzed using a generalized estimating equations model. RESULTS Patients in the intervention group who received the e-HEI intervention reported a statistically higher amount of physical exercise (P=0.02) over a three-month period. There were no statistical differences between the groups in their self-efficacy for exercise and CHD risk factor profile. The results indicated that the e-HEI intervention was feasible and safe to use by the participants in terms of supporting their exercise maintenance, and improving their exercise and health records. CONCLUSIONS The study demonstrated the effectiveness of the e-HEI intervention in meeting the challenge of boosting the amount of physical exercise that CHD patients engaged in over three months. The evidence may benefit healthcare professionals involved in efforts to devise strategic plans on how to apply e-health education and provide continual support to promote exercise initiation and maintenance among Chinese CHD patients in the community.
