To evaluate mediation and moderation of bone on the association of sarcopenic obesity (SO) indices using the metabolic load-capacity model with the 10-year cardiovascular disease risk scores (CVDR). In 2905 men and 3622 women (age ≥ 30 years), dual-energy X-ray absorptiometry was used to measure bone indicators [total bone mineral content percentage(TBM%), bone mineral density of femur neck (BMD_FN) and lumbar spines(BMD_LS)], total muscle (TMM) and fat mass (TFM), appendicular skeletal muscle mass (ASM), and truncal fat mass (TrFM). Two SO indices were TMM/TFM and ASM/TrFM. The Framingham model was used to calculate CVDR. Sex-specific mediation and moderation effects of bone indicators in the associations between the SO indices and the CVDR were analyzed. After adjusting for age, education, income, alcohol use, and physical activity, the SO indices inversely associated with the CVDR and TBM% inversely mediated those associations in both sexes. BMD inversely mediated those associations in men, while the mediation effects of BMD in women were non-significant or positive. In those aged ≥ 60, the mediation effects were found in TBM% and BMD_LS , but not in BMD_FN. The moderation analysis shows stronger inverse associations between the SO indices and the CVDR in those with low bone indicators in women and in men (for the relationship between ASM/TrFM and TBM%), while bone indicators did not moderate these associations in those aged ≥ 60. Bone mass mediated the associations between the SO indices and the CVDR in Korean men and women and moderated these associations in women.

骨骼介导和调节肌肉减少性肥胖指数与心血管疾病风险评分之间的关​​联

使用代谢负荷能力模型和 10 年心血管疾病风险评分 (CVDR) 评估骨骼对肌肉减少性肥胖 (SO) 指数关联的调节和调节。在2905名男性和3622名女性(年龄≥30岁)中,采用双能X线骨密度仪测量骨指标[总骨矿物质含量百分比(TBM%)、股骨颈骨密度(BMD_FN)和腰椎( BMD_LS)]、总肌肉 (TMM) 和脂肪量 (TFM)、附肢骨骼肌量 (ASM) 和躯干脂肪量 (TrFM)。两个 SO 指数是 TMM/TFM 和 ASM/TrFM。Framingham 模型用于计算 CVDR。分析了骨骼指标在 SO 指数和 CVDR 之间的关联中的性别特异性中介和调节作用。在调整年龄、教育、收入、饮酒和体育活动后,SO 指数与 CVDR 和 TBM% 呈负相关,在两性中都呈负相关。BMD 在男性中反向调节这些关联,而 BMD 在女性中的调节作用不显着或为正。在 60 岁以上的人群中,TBM% 和 BMD_LS 有中介效应,BMD_FN 无中介效应。调节分析显示,在女性和男性骨指标低的人群中,SO 指数与 CVDR 之间存在更强的负相关(对于 ASM/TrFM 与 TBM% 之间的关系),而骨指标在 ≥ 年龄的人群中并未缓解这些相关性60. 骨量在韩国男性和女性中调节 SO 指数与 CVDR 之间的关联,并在女性中调节这些关联。BMD 在男性中反向调节这些关联,而 BMD 在女性中的调节作用不显着或为正。在 60 岁以上的人群中,TBM% 和 BMD_LS 有中介效应,BMD_FN 无中介效应。调节分析显示,在女性和男性骨指标低的人群中,SO 指数与 CVDR 之间的负相关性更强(对于 ASM/TrFM 与 TBM% 之间的关系),而骨指标在 ≥ 年龄的人群中并未缓和这些相关性60. 骨量在韩国男性和女性中调节 SO 指数与 CVDR 之间的关联,并在女性中调节这些关联。BMD 在男性中反向调节这些关联,而 BMD 在女性中的调节作用不显着或为正。在 60 岁以上的人群中,TBM% 和 BMD_LS 有中介效应,BMD_FN 无中介效应。调节分析显示,在女性和男性骨指标低的人群中,SO 指数与 CVDR 之间的负相关性更强(对于 ASM/TrFM 与 TBM% 之间的关系),而骨指标在 ≥ 年龄的人群中并未缓和这些相关性60. 骨量在韩国男性和女性中调节 SO 指数与 CVDR 之间的关联,并在女性中调节这些关联。
