The cecond part of the review discusses some inportant issues associated with fall prevention and future perspectives on fall related research. Currently, many kinds of interventions ore availavle for the treatment of patients suffering from osteoporosis, i.e. nutritional supports, medications acting on bone metabolism and exercise. However, a series of meta-analyses showed that only alendronate and risedronate have been proven to prevent non-vertebral tractures in persons with osteoporosis. Anaerobic and weight bearing exercises are known to have a positive effect on the bone mineral density of the spine. There is, however, no reliable data for fracture prevention with exercise alone. Also, the synergistic effect of a combination of these interventions has noto been clearly proven. Although there is evidence that the use of hip protectors in institutional settings reduces the rate of hip fractures, this approach faces the problem of patient acceptance and compliance. Psychosocial problems related to falls such as fear of falling, post-fall syndrone and cost-effectiveness of the prevention programs are becoming increasingly important in elderly health care, but little evidence of such has been reported in the literature. In future perspectives on fall relared research, a theory-based approach for fall prevention needs to be included to explore more effective interventions. We must also consider the double-edged effects of interventions that may increase certain fall risk factors while reducing another. Especially, the relation between activities and incidence of falls is important to consider, because increased activity itself may increase the change of falls. When applying exercise or rehabilitative approaches, the interaction between falls, activity levels, frailty, and injury must be studied much more carefully. In addition, one has to always think about what is the true aim of a program, because the aim of fall prevention goes beyond preventing falls. Although some research has so far been conducted in Europe and the U.S.A. by researchers and practitioners in various fields, the quantity and quality of fall prevention research are still lacking and the available data is therefore insufficient to suggest appropriate decision-making in clinical practice. Especially in Japan, there have been only a few RCTs to determine the effectiveness of fall prevention programs. Because there are many differences in the characteristics of our native population and health care systems vs those of Europe and the U.S.A., it is a critical issue for us to establishi fall prevention programs suited to Japanese population and health care system.
