Effect of a mHealth programme on coronary heart disease prevention among working population in Singapore: A single group pretest-post-test design.

AIM: The aim of this study was to develop and examine the effectiveness of a 4-week Mobile Health (mHealth) programme using the smartphone app Care4Heart on awareness, knowledge, perceived stress, and a heart-related lifestyle among working population in Singapore. DESIGN: A quasi-experimental single group pretest and repeated post-test design. METHODS: A total of 160 nonhealth-related working adults were recruited from February 2016-April 2016. The Care4Heart app was installed on the participants' phones. Outcome measures, including the Heart Disease Fact Questionnaire-2, the Behavioral Risk Factor Surveillance System, and the Perceived Stress Scale were collected online at baseline, 4th week, and 6th month from baseline. RESULTS: Compared with the baseline, the participants had significantly higher total mean scores for awareness and knowledge of coronary heart disease (CHD) after study intervention at 4 weeks and 6 months from baseline. However, there were no significant differences in perceived stress levels and heart-related lifestyle behaviours before and after the intervention. CONCLUSIONS: The study contributed some evidence that the mHealth app helped to improve awareness and knowledge of CHD. IMPACT: Coronary heart disease remains one of the major causes of death and disability. It imposes a heavy financial burden on working adults. However, working adults were less able to identify the risk factors and adopt healthy lifestyles due to gaps in knowledge and awareness. This study demonstrated some effects of a mHealth programme in improving awareness and knowledge of CHD among the working population. mHealth provides a potential avenue for primary prevention of CHD.

Improving awareness, knowledge and heart-related lifestyle of coronary heart disease among working population through a mHealth programme: study protocol.

AIM: To develop a mHealth programme, entitled 'Care4Heart' for the working population in Singapore and thereafter examine its feasibility and effectiveness in increasing the awareness and knowledge of coronary heart disease and improving their heart-related lifestyle. BACKGROUND: Teaching and encouraging the working population to adopt a healthier lifestyle could result in preventing and/or decreasing the incidence of coronary heart disease among this population. The use of mobile application (app) is the next logical wave of healthcare support tools to prevent and manage chronic diseases like coronary heart disease. DESIGN: A quasi-experimental longitudinal study design. METHODS: The study will be conducted in a tertiary university in Singapore. A non-probability, quota sampling of 200 participants will be recruited including 100 academic and research staff, 50 administrative staff and 50 support staff and business owners. Once consent is obtained, the newly developed mobile app will be installed onto the participants' smartphones and a well-trained research assistant will brief the participant on the use of the app. The main outcomes will be measured using the survey questionnaires: Awareness of coronary heart disease, Heart Disease Fact Questionnaire-2, Behavioural Risk Factor Surveillance System and Perceived Stress Scale. Data will be collected at baseline and at the 4th week and 6th month thereafter. DISCUSSION: If this project is successful, Care4Heart - a mHealth and novel prevention educational programme for the working population in Singapore - can be used to promote knowledge and positive heart-related lifestyle changes to prevent coronary heart disease.
