2.  Osteoporosis  Asian region is considered to be on the verge of an emerging osteoporosis epidemic  50% of the world’s osteoporotic hip fractures will occur in Asian women by 2050  Osteoporosis have a higher risk of hip fracture which is a major cause of morbidity and mortality ▪ Hip fracture 1 year mortality among the elderly in Korea was 16.6%, 2.85 times higher than the mortality rate for the general population of 5.8% 2

3.  Osteoporosis  Most individuals with osteoporosis remain undiagnosed and untreated in the U.S.  There have been few published data on diagnosis and treatment rate of osteoporosis in Asia  Prevalences  U.S and Canada, 10% of postmenopausal women have osteoporosis 3

4.  In this study  Prevalence of osteoporosis  Management status ▪ Data from the Korea National Health and Nutrition Examination Survey ; KNHANES 4

5.  KNHANES  Cross sectional, stratified multistage sampling design  Every 3~4 years since 1998  Four different measures ▪ A health interview, a health behavior survey, a health examination, a nutrition survey  2 nd year of 4 th KNHANES’ BMD and other data 5

6.  Athropometric parameters, and BMD  Parameters ▪ AccordHeight ▪ Weight ▪ BMI ▪ BMD : lumbar spine, femoral neck, and total hip by DEXA  Diagnosed by using the WHO T-score criteria ▪ Osteoporosis, osteopenia ▪ -2.5≤T-score≤-1, T-score≤-2.5 calculated from the Asian reference data 6

7.  Physician diagnosis rate and treatment rate  Known cases of osteoporosis  Newly diagnosed cases of osteoporosis  Physician diagnosis rate ▪ No. of known cases / total number of cases  Treatment rate ▪ Currently taking medication / Total no. of cases 7

8.  Statistical analysis  Predictive Analytics Software(PASW) complex-samples procedure was used for the statistical analysis 8

11. Lumbar bone density T-scores tended to be lower than femoral neck’s or hip’s Osteoporosis prevalence Femoral neck 22.4% in women, 3.3% in men Total hip 4% of women, 0.5% of men Lumbar spine 27% of women, 6.0% of men 11

13. Physician diagnosis rate was significantly higher in the females aged 66~68 years than other ages 43.6% vs 28.1%, p<0.05 Treatment rate had no significant difference between females 66~68 ages and other ages 16.9% vs 14.1% p>0.05 13
