성인초기 여성의 골밀도, 생화학적 골표지자 및 골건강 관련 요인 = Bone Mineral Density, Biochemical Bone Turnover Markers and Factors associated with Bone Health in Young Korean Women

다국어 초록 (Multilingual Abstract)

Purpose: This study was done to assess the bone mineral density (BMD), biochemical bone turnover markers (BTMs), and factors associatedwith bone health in young Korean women. Methods: Participants were 1,298 women, ages 18-29, recruited in Korea. Measurementswere BMD by calcaneus quantitative ultrasound, BTMs for Calcium, Phosphorus, Osteocalcin, and C-telopeptide cross-links(CTX), body composition by physical measurements, nutrients by food frequency questionnaire and psychosocial factors associated withbone health by self-report. Results: The mean BMD (Z-score) was -0.94. 8.7% women had lower BMD (Z-score≤ -2) and 14.3% womenhad higher BMD (Z-score≥ 0) than women of same age. BTMs were not significantly different between high-BMD (Z-score≥ 0) andlow-BMD (Z-score<0) women. However, Osteocalcin and CTX were higher in women preferring caffeine intake, sedentary lifestyle andalcoholic drinks. Body composition and Calcium intake were significantly higher in high-BMD. Low-BMD women reported significantlyhigher susceptibility and barriers to exercise in health beliefs, lower bone health self-efficacy and promoting behaviors. Conclusion: Resultsof this study indicate that bone health of young Korean women is not good. Development of diverse strategies to intervene in factorssuch as exercise, nutrients, self-efficacy, health beliefs and behaviors, shown to be important, are needed to improve bone health.
