title: How to reduce the risk factors of osteoporosis in Asia.
abstract: Osteoporosis can be predicted to be a new burden to public health in Asia. Currently, the incidence of osteoporosis-related fractures is lower there than in most western communities. By the year 2050, however, 50% of the 6.3 million hip fractures which occur worldwide will be in Asians as a result of an aging population, a decrease in physical activity and westernization of lifestyles. The cost of treatment and cure of these patients will be enormous, a sufficient financial burden to consume current economic gain and cripple the future advancing development of Asian countries. Individual risk factors for osteoporosis have been identified by the extensive Mediterranean Osteoporosis Study (MEDOS). Fortunately, Asians, the rural population and farmers in particular, have the favorable lifestyle identified by the study, including high physical activity and exposure to sunlight. Strikingly, tea drinking, a daily habit in Asia, is also identified as a protective factor against osteoporosis. In addition, bioflavonoids and phytoestrogen-rich soybeans and vegetables are consumed in large quantities by Asians. A soy diet reduces mortality in breast and prostate cancer because it contains weak estrogens. The weakly estrogenic phytoestrogens require further study to demonstrate their pharmacological effect in reducing the rate of osteoporosis. Public health education, however, is needed to encourage the Asian population to maintain their traditionally good lifestyle and to reduce the risk factors for osteoporosis. In turn, these steps may reduce the public health burden by 2050.
