Dynapenic obesity (DO) is the coexistence of excess adipose tissue/body weight and low muscle strength. This condition is associated with an increased risk of suffering from various chronic diseases and physical deterioration in older people.
To analyze the association between DO phenotypes and physical performance in middle-aged women living in the community.
This cross-sectional study was conducted on middle-aged and older women (≥50 years) residing in Guayaquil, Ecuador. Dynapenia was diagnosticated by a handgrip strength (HGS) < 16 kg; obesity was determined based on body mass index (BMI) ≥ 30 kg/m. Participants were categorized into four groups based on their dynapenia and obesity status: non-dynapenic/non-obesity (ND/NO), obesity/non-dynapenic (O/ND), dynapenic/non-obesity (D/NO) and dynapenic/obesity (D/O). Physical performance was assessed by the Short Physical Performance Battery (SPPB).
A total of 171 women were assessed. The median (IQR) age of the sample was 72.0 (17.0) years. Obesity and dynapenia were 35% ( = 60) and 57.8% ( = 99) of the participants, respectively. The prevalence of ND/NO was 25.1% ( = 43), O/ND 17% ( = 29), D/NO 39.8% ( = 68) and DO 18.1% ( = 31). The mean SPPB total score was 6.5 ± 3.2. Participants of D/NO and DO groups presented significantly lower mean SPPB scores ( < 0.001) compared to those of NO/ND and O/ND groups.
Women with DO and D/NO exhibited significantly lower SPPB scores, indicating poorer physical performance. These findings emphasize the importance of incorporating a comprehensive assessment of muscle strength and obesity in middle-aged and older women.
肌无力性肥胖（DO）是指体内脂肪组织过多/体重超标与肌肉力量低下并存的情况。这种状况与老年人患各种慢性病及身体机能衰退的风险增加有关。
分析社区中年女性中DO表型与身体机能之间的关联。
本横断面研究针对居住在厄瓜多尔瓜亚基尔的中年及老年女性（≥50岁）开展。通过握力（HGS）<16千克诊断肌无力；根据体重指数（BMI）≥30千克/平方米确定肥胖。参与者根据其肌无力和肥胖状况分为四组：非肌无力/非肥胖（ND/NO）、肥胖/非肌无力（O/ND）、肌无力/非肥胖（D/NO）和肌无力/肥胖（D/O）。通过简易体能状况量表（SPPB）评估身体机能。
共评估了171名女性。样本的年龄中位数（四分位间距）为72.0（17.0）岁。肥胖和肌无力的参与者分别占35%（n = 60）和57.8%（n = 99）。ND/NO的患病率为25.1%（n = 43），O/ND为17%（n = 29），D/NO为39.8%（n = 68），DO为18.1%（n = 31）。SPPB总分均值为6.5±3.2。与NO/ND和O/ND组相比，D/NO组和DO组参与者的SPPB平均分显著更低（P<0.001）。
患有DO和D/NO的女性SPPB得分显著更低，表明身体机能较差。这些发现强调了对中老年女性进行肌肉力量和肥胖综合评估的重要性。
