ABSTRACT=<sec id="sec1"><title>Background</title><p>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.</p></sec><sec id="sec2"><title>Aim</title><p>To analyze the association between DO phenotypes and physical performance in middle-aged women living in the community.</p></sec><sec id="sec3"><title>Methods</title><p>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) &lt; 16 kg; obesity was determined based on body mass index (BMI) ≥ 30 kg/m<sup>2</sup>. 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).</p></sec><sec id="sec4"><title>Results</title><p>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% (<italic>n</italic> = 60) and 57.8% (<italic>n</italic> = 99) of the participants, respectively. The prevalence of ND/NO was 25.1% (<italic>n</italic> = 43), O/ND 17% (<italic>n</italic> = 29), D/NO 39.8% (<italic>n</italic> = 68) and DO 18.1% (<italic>n</italic> = 31). The mean SPPB total score was 6.5 ± 3.2. Participants of D/NO and DO groups presented significantly lower mean SPPB scores (<italic>p</italic> &lt; 0.001) compared to those of NO/ND and O/ND groups.</p></sec><sec id="sec5"><title>Conclusion</title><p>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.</p></sec>
