Objective To explore the effects of a health intervention based on the Fogg Behavioral Model on lifestyle, medication adherence, and behavioral intention of prehospital delayed among people at high risk for major adverse cardiac events in the community.Methods The individuals at high risk of adverse cardiac events were divided into 2 groups with 66 cases each according to the communities locations.The control group received conventional health management, while the intervention group received health intervention for 6 months based on the control group, following the Fogg Behavioral Model with three key elements:motivation, ability, and prompt, and followed up for 3month.Health-promoting lifestyle, prehospital delayed behavioral intention, and medication adherence were evaluated in the two groups before intervention, after intervention, and after the follow-up.Results A total of 60 individuals in the control group and 57 in the intervention group completed the intervention and follow-up.After the intervention and follow-up, the scores of health-promoting lifestyle and medication adherence in the intervention group were significantly higher than those in the control group, and the scores of behavioral intention of prehospital delay were significantly lower than those in the control group (all P＜0.05).Conclusion The health intervention based on Fogg Behavioral Model is conducive to improving health-promoting lifestyle and medication adherence, and reducing behavioral intention of prehospital delay among people at high risk of adverse cardiac events in the community.
