본 연구는 2008~2010년 국민건강영양조사에 참여한 50세 이상 폐경 후 여성 2,701명을 대상으로 전신, 대퇴골 전체, 대퇴골 경부, 요추 골밀도와 관련된 요인들을 규명하고자 수행되었으며 연구결과는 다음과 같다. 1. 대퇴골전체, 대퇴골경부, 요추부위의 골감소증 유병률은 37.4%, 54.5%, 45.4%였고 대퇴골 전체, 대퇴골경부, 요추부위의 골다공증 유병률은 6.2%, 25.6%, 34.3%였다. 2. 나이와 신장, 체중, BMI와 같은 신체계측지수는 전신, 대퇴골 전체, 대퇴골 경부, 요추의 골밀도를 결정하는 주요 관련인자였다. 폐경 후 여성의 전신 골밀도에는 체중이, 대퇴골 전체, 대퇴골 경부, 요추 골밀도에는 나이가 가장 영향력 있는 변수였다.
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 ≥ 50 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.
