越来越多的证据表明，主观衰老--即个体如何看待自己的衰老过程--对健康和晚年生存的影响。本文的目的是通过荟萃分析来综合现有纵向研究的结果。在《心理信息学》、《科学网络》、《科学科普》和《Pubmed》中进行系统搜索后，有19项纵向研究报告了主观衰老对健康、健康行为和寿命的影响。作者使用随机效应荟萃分析结合了这些研究中报告的结果，假设不同研究的效应大小会有所不同。Meta分析得出主观老龄化的总体显著影响(似然比=1.429；95%可信区间=1.273-1.604；p<；.001)。这些分析显示了异质性，对于随访时间较短的研究、健康与生存的研究、较年轻参与者的研究(研究的平均年龄在57岁至85岁之间，中位数为63岁)以及在国家提供的福利最少的福利系统中的研究，影响更大。然而，无论是主观老龄化的不同操作方式，还是研究质量，效果都没有差异。主观老龄化对健康、健康行为和生存的影响不大。需要进一步的理论概念化和实证研究来确定主观衰老如何有助于健康和生存。
Evidence is accumulating on the effects of subjective aging-that is, how individuals perceive their own aging process-on health and survival in later life. The goal of this article is to synthesize findings of existing longitudinal studies through a meta-analysis. A systematic search in PsycInfo, Web of Science, Scopus, and Pubmed resulted in 19 longitudinal studies reporting effects of subjective aging on health, health behaviors, and longevity. The authors combine the outcomes reported in these studies using a random effects meta-analysis, assuming that there would be differences in effect sizes across studies. The meta-analysis resulted in an overall significant effect of subjective aging (likelihood ratio = 1.429; 95% confidence interval = 1.273-1.604; p < .001). The analyses revealed heterogeneity, with stronger effects for studies with a shorter period of follow-up, for studies of health versus survival, for studies with younger participants (average age of the studies varies between 57 and 85 years with a median of 63 years), and for studies in welfare systems where state provisions of welfare are minimal. However, effects did not vary either across different operationalizations of subjective aging or by study quality. Subjective aging has a small significant effect on health, health behaviors, and survival. Further theoretical conceptualizations and empirical studies are needed to determine how subjective aging contributes to health and survival.
