Sarcopenia is an important factor of functional impairment related to aging. This study conducted investigate the prevalence sarcopenia and sarcopenic obesity in Korean population. Representative men (4,486) women (5,999) aged 20 years or older were analyzed from Fourth National Health Nutritional Examination Surveys. was classified into Class I defined relative skeletal muscle mass loss within 1–2 SD gender-specific mean for healthy young adults II below 2 SD. Relative represented by...

Hip fracture is a major public health problem. Earlier studies projected that the total number of hip will increase dramatically by 2050, and most occur in Asia. To date, only few provided updated projection, none them focused on projection Thus, it essential to provide up date prediction Asia, evaluate direct medical cost We 9 Asian Federation Osteoporosis Societies members using incidence rate population size. show from 1,124,060 2018 2,563,488 2.28-fold increase.

Objective: this study examined the association of physical activity with sarcopenia and sarcopenic obesity among community-dwelling Korean elderly. Methods: subjects consisted 2,264 aged 65 years or older in 2008–09 Korea National Health Nutrition Examination Survey. Sarcopenia was defined as 2 SD below mean appendicular skeletal muscle/weight for healthy young adults. Obesity waist circumference ≥90 cm men ≥85 women. Levels were classified using metabolic equivalent task method. Results:...

For the prevention of osteoporotic fracture, adequate screening and treatment are important. However, there few published data on diagnosis rates osteoporosis in Asia. We used from fourth Korea National Health Nutrition Examination Survey 2008-2009 to estimate nationwide prevalence, physician rate, rate adults aged 50 years older. The bone mineral density (BMD) measurements central skeletal sites (lumbar spine, femoral neck, total hip) were obtained using dual-energy X-ray absorptiometry...

several studies have found nutrients, including antioxidants, to be associated with sarcopenia. However, whether specific foods, such as vegetables and fruits, are sarcopenia has not been studied.to examine the association of frequency fruits consumption in older people.this study used cross-sectional data from Fourth Korea National Health Nutrition Examination Survey 2008-09. Subjects were community-dwelling 823 men 1,089 women aged ≥65 years. Frequency food group was obtained by using...

Recently, it was reported that 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase inhibitors increased bone mineral density (BMD) in mice. We studied the effect of HMG-CoA on BMD type 2 diabetes mellitus by a retrospective review medical records. Sixty-nine diabetic patients were included. The control group (n = 33) did not take inhibitors. treatment 36) administered either lovastatin, pravastatin, or simvastatin. spine, femoral neck, trochanter, and total hip measured dual-energy...

We investigated the cutoff values of surrogate insulin resistance for diagnosing metabolic syndrome in Korean adults. The data from 976 non-diabetic individuals (484 men and 492 women) aged 30-79 yr were analyzed. determined odds ratios prevalence according to quartiles fasting insulin, homeostasis model (HOMA-IR), quantitative sensitivity check index (QUICKI) as independent variables, while adjusting age, sex, body mass index. HOMA-IR, QUICKI estimated by areas under receiver-operating...

It is well established that insulin-like growth factor (IGF)-I critical for the regulation of peak bone mineral density (BMD) and width. However, role systemic vs. local IGF-I not understood. To determine plays in regulating BMD width, we crossed flox/flox mice with procollagen, typeIIalphaI-Cre to generate conditional mutants which chondrocyte-derived was disrupted. Bone parameters were measured by dual X-ray absorptiometry at 2, 4, 8, 12 wk age peripheral quantitative computed tomography...

Abstract Background Serum vitamin D levels have been reported to be associated with individual components of body composition. However, the relationship between serum and combined indices adverse composition is largely unknown. This cross‐sectional study examined association osteosarcopenic obesity in a nationally representative sample middle‐aged older adults. Methods We analysed Korea National Health Nutrition Examination Surveys (IV V) conducted 2008–2010, consisting 5908 (2485 men, 3423...

Osteoporosis is a major health issue. By 2050, greater than 2-fold increase in patients number with hip fractures will occur Asia representing 50% of all worldwide. For the Asia-Pacific (AP) region, more efforts on controlling osteoporosis and subsequent are crucial. Bone mineral density (BMD) by dual energy X-ray absorptiometry (DXA) commonly used to diagnose monitor treatment. However, inconvenience, cost, limited availability DXA delay detection BMD changes after treatment initiation...

BackgroundDenosumab is a potent anti-resorptive agent widely used for osteoporosis. However, its discontinuation results in 'rebound phenomenon' of rapid bone loss, necessitating transition to alternative therapies. Despite this, there limited evidence guide the selection most effective agent, particularly among bisphosphonates. This study aimed evaluate efficacy different therapies following denosumab real-world clinical setting. MethodsThis retrospective included 360 patients (low-dose...
