As the proportion of the elderly population increases rapidly, interest in musculoskeletal health is also emerging. Here, we investigated how antioxidant vitamin intake and musculoskeletal health are related. Adults aged 50 to 80 years with a body mass index (BMI) of 18.5 to 27.0 kg/m were included. Bone mineral density (BMD), lean mass (LM), appendicular skeletal muscle mass index (ASMI) were measured using dual-energy X-ray absorptiometry (DXA), and the grip strength and knee extension using hand dynamometer. Nutrient intakes were measured using a 24-hour recall questionnaire. A total of 153 adults (44 men and 109 women) participated in this study. A partial correlation analysis showed a significant positive relationship between vitamin E and BMD and between vitamin C and LM/Height. Participants were classified into three groups according to whether their vitamin E and C intake met the recommended intake for Dietary Reference Intakes for Koreans (KDRIs). The prevalence of having low T-score (< -1.0) and low ASMI (< 7.0 for men and < 5.4 for women) was 51.3% and 15.4% in the group with vitamins C and E intakes below KDRIs. After adjusting for sex, smoking status and energy, protein, vitamin D, and calcium intake, the group with vitamins C and E both below the KDRIs displayed a significantly lower BMD at all test sites and LM/Height compared with vitamin C and/or E intake above the KDRIs groups. We conclude that sufficient intake of vitamin E and C is important for maintaining BMD and lean mass in Korean adults over 50 years of age.
随着老年人口比例迅速增加，对肌肉骨骼健康的关注也日益凸显。在此，我们研究了抗氧化维生素摄入量与肌肉骨骼健康之间的关系。纳入了年龄在50至80岁、体重指数（BMI）为18.5至27.0 kg/m的成年人。使用双能X线吸收法（DXA）测量骨矿物质密度（BMD）、瘦体重（LM）、四肢骨骼肌质量指数（ASMI），并使用握力计测量握力和膝关节伸展力。通过24小时回顾性问卷来测量营养素摄入量。共有153名成年人（44名男性和109名女性）参与了本研究。偏相关分析显示维生素E与BMD之间以及维生素C与LM/身高之间存在显著正相关。根据维生素E和C的摄入量是否符合韩国膳食参考摄入量（KDRIs）的推荐摄入量，将参与者分为三组。在维生素C和E摄入量低于KDRIs的组中，T值低（< -1.0）和ASMI低（男性< 7.0，女性< 5.4）的患病率分别为51.3%和15.4%。在调整性别、吸烟状况以及能量、蛋白质、维生素D和钙的摄入量后，与维生素C和/或E摄入量高于KDRIs的组相比，维生素C和E摄入量均低于KDRIs的组在所有测试部位的BMD和LM/身高均显著更低。我们得出结论，充足摄入维生素E和C对于维持50岁以上韩国成年人的BMD和瘦体重很重要。
