Biological age (BA) can be used to measure the aging process of individuals and make up for the deficiency that chronological age cannot explain the discrepancy of health status among individuals at same chronological age. In recent years, multiple measurements of BA based on clinical or phenotypic, molecular biological, or compound indicators have emerged. In the paper, we summarize some common measurements of BA and compare their validities.利用生物学年龄衡量个体的衰老进程,可以弥补实足年龄难以解释同龄个体间健康水平差异的缺陷。近年来,涌现出多种基于临床或表型、分子生物学指标或复合型指标的生物学年龄测量方法。本文对一些常见的生物学年龄评价指标进行概述,并比较这些评价指标的效度。.
