背景/目的：生物电阻抗分析（BIA）是一种相对简单、廉价和无创的身体成分测量技术，因此适用于野外研究和大型调查。研究对象/方法：我们对55项已发表的6-80岁健康人群的bia来源的体脂百分比（BF%）进行了概述。此外，在BIA的背景下，体重指数（BMI）与身体成分之间的关系被证明是一个很好的替代方法，可以密切区分哪种身体成分与心血管疾病（cvd）和全因死亡率的风险更相关。结果和结论：bia估计的BF百分比随人群和年龄变化很大。bia估计的BF%与各种健康结果（如心血管疾病）直接密切相关，这与BMI相反，BMI高和低都与患慢性疾病的风险增加有关。包括BIA在内的研究表明，低BMI可能反映了低肌肉和高BMI脂肪量（FM）。bia衍生的瘦肉和鱼粉与发病率和死亡率直接相关。相反，BMI在流行病学研究中用于测量BF%的作用相当有限。
BACKGROUND/OBJECTIVES: Bioelectrical impedance analysis (BIA) is a relatively simple, inexpensive and non-invasive technique to measure body composition and is therefore suitable in field studies and larger surveys.SUBJECTS/METHODS: We performed an overview of BIA-derived body fat percentages (BF%) from 55 published studies of healthy populations aged 6-80 years. In addition, the relationship between body mass index (BMI) and body composition is documented in the context of BIA as a good alternative to closely differentiate which composition of the body better relates to the risk of cardiovascular diseases (CVDs) and all-cause mortality.RESULTS AND CONCLUSIONS: BIA-estimated percentage of BF varies greatly with population and age. BIA-estimated BF% is directly and closely related to various health outcomes such as CVDs, which is in contrast to BMI where both high and low BMIs are associated with increased risk of developing chronic diseases. Studies, among others using BIA, suggest that low BMI may reflect low muscle and high BMI fat mass (FM). BIA-derived lean and FM is directly associated with morbidity and mortality. To the contrary, BMI is rather of limited use for measuring BF% in epidemiological studies.
