Recently bone health is an important issue in public health aspect and calcium is the most critical nutrient to influence bone mass and bone mineral density, and consequently bone fracture. Calcium DRIs of Korea are much lower than those of US/Canada which have been revised recently. Since the requirement of calcium in Asians may be different from Caucasian, it would be desirable for Korean DRIs for calcium to be established by Korean data; however, little data of high quality exist. Based on 2008–2010 Korea National Health and Nutrition Examination Survey data, most women aged 65 and more have bone health problems such as osteoporosis and osteopenia. In women and men aged 65 and more, higher calcium intake was significantly associated with higher bone mineral density as well as lower incidence of osteoporosis. Means of the highest quartile calcium intake, which are 750 mg for women and 930mg for men, are much higher than the present Estimated Average Requirements (EAR) of elderly women and men, which are 570 mg and 560 mg, respectively. Therefore, it seems valid to increase calcium EAR for Korean elderly. (This research was supported by a fund(2012‐E35004–00) by Research of Korea Centers for Disease Control and Prevention)
