The purpose of this study was to investigate factors associated with Bone Mineral Density (BMD) in Korean postmenopausal women. The data from 2008-2010 Korean National Health and Nutrition Examination Survey (KNHANES) were used for data analysis. Subjects were 2,701 postmenopausal women aged years. BMDs at whole body, total femur, femoral neck, and lumbar spine were measured by Dual-energy X-ray absorptiometry (DXA). Dietary data from 24-hour dietary recall and a food frequency questionnaire containing 63 food items were used. The proportions of osteopenia at total femur, femoral neck, and lumbar spine were 37.4%, 54.5%, and 45.4%, respectively. The proportions of osteoporosis at total femur, femoral neck, and lumbar spine were 6.2%, 25.6%, and 34.3%, respectively. Age, anthropometric index including height, weight, and Body Mass Index (BMI), parathyroid hormone, and physical activity were related to BMD, but the relationships were site specific. Total femur BMD was explained by age, weight, parathyroid hormone and intakes of carbohydrate and fruits. Femoral neck BMD was related to age, weight, parathyroid hormone and intakes of riboflavin and fruits. Lumbar spine BMD was associated with age, weight, milk and dairy products, calcium intake, and exercise. These results indicated that adequate intakes of milk and dairy products, fruits, carbohydrate, calcium, riboflavin and exercise as well as weight maintenance might play an important role in maintaining optimum bone health in Korean postmenopausal women.
