The number of patients with osteoporosis is an estimated 12,800,000 in Japan. Osteoporosis represents a risk factor for becoming bedridden, and also for increased mortality. It would thus be important to take measures to prevent non-examination and treatment interruption as their rate is high. We recruited participants at a health-supporting event for local residents at our pharmacy on April 14, 2019 and obtained consent from 40 individuals to participate in this study. At this event held by a pharmacy, we conducted bone density measurement and osteoporosis-related preventive education by pharmacists, considering the influence the event had on health-related awareness and behavior in the local residents. Knowledge of osteoporosis was higher after than before the events. Participant health and lifestyle awareness was not observed between before the event and one month after the event. However, one month after the event, several changes could be observed in the behavior of 79.4% (27/34) of the participants. Based on these results, bone density measurement and osteoporosis-related preventive education by pharmacists are suggested to increase osteoporosis-related knowledge among local residents and to promote behavior change related to healthcare and osteoporosis.
