The purpose of this study was to investigate the effects of health promotion class on participation rate, scales of profile of mood state (POMS scales) and physical characteristics. Fifty six subjects, whose age ranged from 40 to 69 years, participated. They were divided into 2 groups: 30 participants who already had exercise habits (EH group) at the time of participation, and 26 other participants who had been sedentary (S group). The health promotion classes were held 90 min per class, once a month, and for 6 months. The primary intervention of the class was based on supportive personal interview which is based on psychiatric therapy. In addition, simple weight training and stretching were instructed for 30 min. The participation rates for EH group and S group were 78.3±21.1% and 84.0±18.5%, respectively. Body weight, body mass index, percentage of body fat, and waist in both group significantly decreased at the end of the class. The number of steps on average in S group significantly increased at the end of the class. In EH group, the fatigue score of POMS significantly decreased. On the other hand in group S, the scores of depression, anger and fatigue significantly decreased, while vigor increased. In conclusion, the health promotion class based on supportive personal interview was effective on changing physical characteristics and POMS scores.
