To establish the relationships between age, sex, anthropometric measurements and bioelectrical impedance, 446 healthy subjects (242 men and 204 women), aged 17 to 88 years, were enrolled in our study. Anthropometric parameters included body weight, height, body mass index (BMI), skinfold thickness of the triceps (TSF), and arm muscle circumference (AMC). Using the BIA-106, RJL System, the bioelectrical resistance, bioelectrical reactance and phase angle were measured. Correlation analysis revealed a significant correlation between gender, anthropometry and bioelectrical resistance. A significant correlation between age, anthropometry and reactance was also noted. Both male and female subjects in the fourth quartile of the age distribution showed significantly lower reactance and phase angle. The quartile study of the body mass index revealed corresponding changes in weight, BMI, TSF, AMC and resistance in quartiles, but not reactance. In conclusion, in addition to anthropometry, gender has an effect on bioelectrical resistance, and age has an effect on reactance.
为了确定年龄、性别、人体测量指标与生物电阻抗之间的关系，我们招募了446名年龄在17至88岁之间的健康受试者（242名男性和204名女性）参与本研究。人体测量参数包括体重、身高、体重指数（BMI）、肱三头肌皮褶厚度（TSF）和上臂肌肉周长（AMC）。使用RJL系统的BIA - 106测量生物电阻抗、生物电抗和相位角。相关性分析显示性别、人体测量指标与生物电阻抗之间存在显著相关性。年龄、人体测量指标与电抗之间也存在显著相关性。年龄分布第四四分位数中的男性和女性受试者的电抗和相位角均显著较低。体重指数的四分位数研究显示，四分位数中的体重、BMI、TSF、AMC和电阻有相应变化，但电抗没有。总之，除人体测量指标外，性别对生物电阻抗有影响，年龄对电抗有影响。
