The effect of an instant message-based lifestyle and stress management intervention on the reduction of cardiovascular disease risk

Aim This study investigated the effectiveness of an instant message-based lifestyle and stress management intervention delivered by nurses on cardiovascular disease risk reduction. Methods In this nonrandomized concurrent controlled trial conducted from March 2013 to September 2013, 164 eligible employees in two companies were assigned to the intervention (n = 83) and control (n = 81) groups based on their worksites. Only participants were blinded to group assignment. All participants received two education sessions during 1 month, and the intervention group also received an instant message-based lifestyle and stress management intervention for 5 months. The primary outcome was the Framingham Risk Score, and the data were collected at the first month and the sixth month. Results The final analysis included 80 participants in the intervention group and 76 in the control group. After the intervention, significant intervention effects were found for the mean value and the changes of the Framingham Risk Score and the proportion of participants who improved their diet and exercise (P < 0.05). There were trends for improvement in the proportion of smoking and levels of stress, but statistically significant levels (P > 0.05) were not met. Conclusion An instant message-based lifestyle and stress management intervention can reduce cardiovascular disease risk in high-risk individuals.
