This study is designed to furnish basic data for development of health-care program to promote health of the middle-aged adult by making the middle-aged adult an object who have radically increasing death rate because of chronic degenerative diaease, finding out the executive degree of health-promoting behaviors, and verifying the relation between self-efficacy/perceived health status and health-promoting behaviors. The results are as follows. 1) The hypothesis that 'the higher the self-efficacy, the better the health-promoting behaviors' was supported on a meaningful level(r=.30l, p=.000) 2) The hypothesis that 'The health-promoting behaviors will have differences according to the perceived health status' was supported on a meaningful level in the sections of the control of stress(p=.000), the self-achievement (p=.000), the exercise(p=.002), the control of interpersonal relation(p=.014) and the eating habit(p=.061) and was rejected in the sections of drinking' smoking(p=.787), heath-responsibility (p=.061). The fact that executive degree of health-promoting life-style have correlation with self-efficacy was found out and we need to develop health-education program to promote self-efficacy.
