The last decade has seen the emergence of a new condition, describing the coexistence of obesity and sarcopenia, termed Sarcopenic Obesity (SO). The aim of this study was to assess the potential association between SO and reduced Resting Energy Expenditure (REE).
Body composition and REE were measured using a bioimpedance analyser (Tanita BC-418) and Indirect Calorimeter (Vmax Encore 229), respectively in 89 adults with overweight or obesity of both genders, referred to the Outpatient Clinic of the Department of Nutrition and Dietetics at Beirut Arab University (Lebanon). Participants were then categorized on the basis of having SO or not.
Thirty-nine of the 89 participants met the criteria for SO (43.8%), and these participants displayed a significantly lower REE per unit body weight than those in the group without SO (19.02 ± 2.26 vs. 20.87 ± 2.77; p = 0.001). Linear regression analysis showed that the presence of SO decreases REE by 1.557 kcal/day for each kg of body weight (β = -1.557; CI = -0.261 - (-0.503); p = 0.004), after adjusting for age and gender.
SO appears to be present in a high proportion of treatment-seeking adults with overweight or obesity of both genders, and it seems to be associated with a reduced REE, compared with those without SO. Future studies are needed to clarify whether this may influence clinical outcomes.
在过去十年中出现了一种新情况，即肥胖与肌肉减少症并存，称为肌肉减少性肥胖（SO）。本研究的目的是评估SO与静息能量消耗（REE）降低之间的潜在关联。
分别使用生物电阻抗分析仪（Tanita BC - 418）和间接热量计（Vmax Encore 229）测量了89名超重或肥胖的成年男女的身体成分和REE，这些参与者均转诊至黎巴嫩贝鲁特阿拉伯大学营养与饮食系门诊。然后根据是否患有SO对参与者进行分类。
89名参与者中有39名符合SO标准（43.8%），这些参与者每单位体重的REE显著低于无SO组（19.02±2.26 vs. 20.87±2.77；p = 0.001）。线性回归分析表明，在调整年龄和性别后，每增加1千克体重，SO的存在会使REE降低1.557千卡/天（β = -1.557；CI = -0.261 - (-0.503)；p = 0.004）。
在寻求治疗的超重或肥胖成年男女中，SO的比例似乎很高，与无SO者相比，它似乎与REE降低有关。需要进一步的研究来阐明这是否会影响临床结果。
