Background: The prevalent vertebral fracture (VF) is a risk factor for future VF, which can be decreased with drug therapy. However, most VFs are not recognized clinically. VFA by DXA and spine X-ray can be performed to detect these prevalent VFs.Objectives: This study aimed to estimate the costs, effectiveness, and radiation exposure of VF diagnostic strategies.Methods: Markov model over a 10-year period was used to calculate the ...

Objectives: To prevent future osteoporosis, it is important to identify factors that affect bone health in adolescents as well as adults. This study aimed to examine the relationship between lipid profiles and insulin resistance and BMC in Korean adolescent population.Methods: Data from 706 boys and 621 girls who participated in the Korea National Health and Nutrition Examination Survey from 2008 to 2011 were analyzed. Lipid profiles were measured, and h...

Engulfment adaptor phosphotyrosine-binding (PTB) domain containing 1 (GULP1) is an adaptor protein involved in the engulfment of apoptotic cells via phagocytosis. Although GULP1 is widely expressed in various tissues, including the brain, muscle, testis, and bone, the function of GULP1 has not been well studied. Here, we investigated whether GULP1 plays a role in the regulation of bone remodeling and examined its expression in bone cells. Conditional Gulp1 floxed mice...

Background and objectives: The association between excess calcium intake and cardiovascular mortality has been reported, but the association has not yet been explored according to serum vitamin D status. Thus, we investigated the relation of dietary calcium intake and Framingham risk score (FRS) according to serum 25-hydroxyvitamin D (25(OH)D) status.Methods: A total of 7809 subjects (3452 males and 4357 female) aged over 40 years from the data of the Ko...

Background: Asian-specific prediction model for estimating the individual risk of osteoporotic fracture was rare. We aimed to develop a Korean fracture risk prediction model using clinical risk factors and assess external validity of the final model.Methods: A total of 718,306 Korean men and women aged 50–90 were followed for 7 years in national system based cohort study. Fifty percent were randomly assigned to the development dataset and 50% to the...

Background and objectives: Fracture in rheumatoid arthritis (RA) patient is more frequent than general population. One of the important reasons is use of glucocorticoid (GC) for treatment of RA. In this study, we aimed to identify the effect of GC on fracture of different site.Methods: Among RA patients ≧19 years, we established a retrospective cohort using Korean national healthcare claims database from Jan 2010 to Dec 2010, and then followed up unti...

Background: In 2004, we reported a 48.1% prevalence of osteoporosis in an Ibansung cohort. The current prospective intervention study was undertaken in order to estimate the prevalence of osteoporosis from 2004 to 2015 and the increasing treatment rate of osteoporosis following osteoporosis screening tests with ultrasound bone densitometry and education in the same cohort.Methods: From November 1, 2014 to August 31, 2015, 960 adults ≥50 years of ag...

Background and objective: Recent studies have demonstrated that higher serum 25-hydroxyvitamin D (25(OH)D) had a favorable effect on bone health. Osteocalcin, however, according to its serum concentration showed different outcomes for bone and aortic calcification. The aim of this cross-sectional study was to compare the bone mineral density (BMD) and coronary artery calcification score (CACS) according to the serum concentration of 25-hydroxyvitamin D and osteocalcin.<p c...

Introduction: The purposes of this study were to evaluate the trends in the incidence and mortality of hip fracture between 2008 and 2012, and predict the number of hip fractures in Korea up to 2025, using nationwide claims data.Methods: Nationwide claims data managed by the National Health Insurance Service (NHIS) was used to identify patients with hip fracture. All new visits or admissions to medical institutes for hip fracture aged 50 years or more be...

Introduction: Vertebral fracture has been recognized as a major health concern. Our purposes were to evaluate the trends in the incidence and mortality of vertebral fracture between 2008 and 2012 and predict the number of vertebral fracture that will occur in Korea up to 2025, using nationwide data from the National Health Insurance Service (NHIS).Method: A nationwide data set was evaluated to identify all new visits to medical institutes for vertebral f...
