Older adults with sarcopenic obesity (SO) are at increased risk of adverse health outcomes. It has not been identified which pattern of macronutrient intake is appropriate in relation to SO. We aimed to compare the patterns of macronutrient intake for predicting SO in older adults. Data from a total of 3828 older adults who participated in the 2008-2011 Korea National Health and Nutrition Examination Survey were analyzed. The one-day 24 h dietary recall method was used to assess macronutrient intake. SO was defined by a combination of body mass index (BMI) ≥ 25 kg/m and BMI adjusted-appendicular skeletal muscle mass <0.789 for men and <0.512 for women. Weighted logistic regression analysis revealed the odds ratio (95% confidence interval) for SO of total calorie intake per 100 increments and carbohydrate (CHO) intake (g/kg/day) per 1 increment to be 0.95 (0.91-0.99) and 0.83 (0.74-0.94), respectively, after adjusting for confounding variables in women. The predictive power for SO of CHO intake (g/kg/day) was higher compared with the other patterns of macronutrient intake both in men and women. In conclusion, total calorie intake and CHO intake (g/kg/day) are inversely related to SO in women. CHO intake (g/kg/day) could be the best index for determining SO.
患有肌肉减少性肥胖症（SO）的老年人健康状况恶化的风险增加。尚未确定哪种宏量营养素摄入模式与 SO 相关。我们旨在比较宏量营养素摄入模式以预测老年人的 SO。对参加 2008-2011 年韩国国家健康和营养检查调查的总共 3828 名老年人的数据进行了分析。使用为期一天的 24 小时膳食回忆法来评估宏量营养素的摄入量。SO 是通过 BMI（≥25kg/m2）和 BMI 调整后的四肢骨骼肌质量（男性<0.789，女性<0.512）相结合来定义的。加权逻辑回归分析表明，女性中总热量摄入每增加 100 卡路里和碳水化合物（CHO）摄入（g/kg/天）每增加 1 个单位的 SO 的比值比（95%置信区间）分别为 0.95（0.91-0.99）和 0.83（0.74-0.94），调整了混杂变量后。与男性和女性中的其他宏量营养素摄入模式相比，CHO 摄入（g/kg/天）对 SO 的预测能力更高。总之，女性的总热量摄入和 CHO 摄入（g/kg/天）与 SO 呈负相关。CHO 摄入（g/kg/天）可能是确定 SO 的最佳指标。
