To determine if anthropometric variables, body composition, medication and gender are associated with functional performance and to compare these variables between octogenarians with high and low functional performance.
Observational, cross-sectional study. Weight, height, body mass index (BMI), waist circumference (WC), and waist-to-height ratio (WHtR) were evaluated. Handgrip strength (HGS) was assessed. Participants' body composition was assessed by dual-energy X-ray absorptiometry (DXA) and functional performance by Short Physical Performance Battery (SPPB). A binomial logistic regression was performed.
One hundred and twenty-two octogenarians were included and separated into high and low function groups. The high function group showed lower values of WHtR (mean difference [MD] = 0.047, P = 0.025) and body fat (BF%) (MD = 3.54, P = 0.032) and higher values of apendicular skeletal muscle mass (ALM) (MD = 3.03, P = 0.001), HGS (MD = 6.11, P = 0.001) and SPPB score (MD = 4.20, P = 0.001). Women were more likely to be classified as low function (OR = 3.66, P = 0.002) and males showed 5.21 odds ratio (P = 0.021) of having high functional performance compared to females. Also, each decrease in age and medication use displayed 1.30 (P = 0.007) and 1.26 odds ratio increases (P = 0.008) in high functional performance.
Older males display better functional performance than women, and decrements in age and medications increase the high functional performance odds ratio. Octogenarians with high functional performance displayed lower BF measurements and higher values of muscle mass and strength.
确定人体测量变量、身体成分、药物治疗和性别是否与功能表现相关，并比较功能表现高和低的八旬老人之间的这些变量。
观察性横断面研究。评估体重、身高、体重指数（BMI）、腰围（WC）和腰高比（WHtR）。评估握力（HGS）。通过双能X线吸收法（DXA）评估参与者的身体成分，通过简短体能表现量表（SPPB）评估功能表现。进行二项逻辑回归分析。
纳入122名八旬老人，并分为功能高和低两组。功能高的组WHtR值较低（平均差[MD]=0.047，P=0.025）和体脂（BF%）较低（MD=3.54，P=0.032），而四肢骨骼肌质量（ALM）较高（MD=3.03，P=0.001）、HGS较高（MD=6.11，P=0.001）和SPPB评分较高（MD=4.20，P=0.001）。女性更有可能被归类为功能低（比值比[OR]=3.66，P=0.002），与女性相比，男性功能表现高的比值比为5.21（P=0.021）。此外，年龄和药物使用的每减少一项，功能表现高的比值比分别增加1.30（P=0.007）和1.26（P=0.008）。
老年男性的功能表现优于女性，年龄和药物使用的减少会增加功能表现高的比值比。功能表现高的八旬老人体脂测量值较低，肌肉质量和力量值较高。
