Objective To investigate the level of health behaviors in adult patients with epilepsy and related influencing factors.Methods Health-Promoting Lifestyle Profile II （HPLPII）， General Self-efficacy Scale （GSES）， and Social Support Rating Scale （SSRS） were used to conduct a questionnaire survey among 55 adult patients with epilepsy and 60 normal adults matched for sex， age， and educational level， and a statistical analysis of data was performed.Results Compared with the normal control group， the epilepsy group had significantly lower total score of health behaviors （110.33±16.35 vs 140.26±19.65， P<0.05）， score of self-efficacy（2.46±0.24 vs 31.26±3.89， P<0.05）， and total score of social support （36.67±6.89 vs 41.56±7.97， P<0.05）. The correlation analysis showed that the total score of health behaviors was positively correlated with monthly income， score of self-efficacy， and total score of social support （P<0.01） and was negatively correlated with the course of disease （P<0.01）.Conclusions There is a relatively low level of health behavior among adult patients with epilepsy. When developing intervention regimens， the medical staff should focus on enhancing patients’ self-efficacy and social support， so as to improve the formation of health behaviors.
