We analyzed the differences in fat-free mass (FFM) according to serum vitamin D level (VitD) and daily calcium intake (Ca) in 14,444 adults aged over 19 years. We used data from the 4th and 5th Korea National Health and Nutrition Examination Surveys (2008-2011). FFM was measured using dual-energy X-ray absorptiometry. VitD was classified as insufficient or sufficient (cutoff: 20 ng/mL). Ca was classified as unsatisfactory or satisfactory (recommended daily intake: 700 mg). In men, the FFM of group 2 (VitD ≥ 20 ng/mL; Ca < 700 mg), group 3 (VitD < 20 ng/mL; Ca ≥ 700 mg) and group 4 (VitD ≥ 20 ng/mL; Ca ≥ 700 mg) was 0.50 kg (95% confidence interval (CI), 0.084-0.92), 0.78 kg (95% CI, 0.26-1.29) and 1.58 kg (95% CI, 0.95-2.21) higher than that of group 1 (VitD < 20 ng/mL; Ca < 700 mg), respectively. In women, a 1 ng/mL increase in VitD was associated with a 0.023 kg increase in FFM (95% CI, 0.003-0.043) and a 1 g increase in Ca was associated with a 0.62 kg increase in FFM (95% CI, 0.067-1.16). High VitD and Ca were associated with a high FFM.
我们分析了14444名19岁以上成年人中，根据血清维生素D水平（VitD）和每日钙摄入量（Ca）划分的去脂体重（FFM）差异。我们使用了第四和第五次韩国国家健康与营养检查调查（2008 - 2011年）的数据。FFM通过双能X线吸收法测量。VitD分为不足或充足（临界值：20 ng/mL）。Ca分为不达标或达标（每日推荐摄入量：700 mg）。在男性中，第二组（VitD≥20 ng/mL；Ca＜700 mg）、第三组（VitD＜20 ng/mL；Ca≥700 mg）和第四组（VitD≥20 ng/mL；Ca≥700 mg）的FFM分别比第一组（VitD＜20 ng/mL；Ca＜700 mg）高0.50 kg（95%置信区间（CI），0.084 - 0.92）、0.78 kg（95%CI，0.26 - 1.29）和1.58 kg（95%CI，0.95 - 2.21）。在女性中，VitD每增加1 ng/mL与FFM增加0.023 kg（95%CI，0.003 - 0.043）相关，Ca每增加1 g与FFM增加0.62 kg（95%CI，0.067 - 1.16）相关。高VitD和高Ca与高FFM相关。
