There is increasing evidence that subjective caregiver burden is an important determinant of clinically significant anxiety in family carers. This meta-analysis aims to synthesise this evidence and investigate the relationship between subjective caregiver burden and anxiety symptoms in informal caregivers. We searched PubMed, CINAHL and PsycINFO up to January 2020. Combined estimates were obtained using a random-effects model. After screening of 4,312 articles, 74 studies (with 75 independent samples) were included. There was a large, positive association between subjective caregiver burden and anxiety symptoms (r = 0.51; 95% CI = 0.47, 0.54; I2 = 0.0%). No differences were found in subgroup analyses by type of study design (cross-sectional vs. longitudinal), sampling, control of confounders or care-recipient characteristics. Subjective caregiver burden is an important risk factor for anxiety in informal caregivers. Targeting subjective caregiver burden could be beneficial in preventing clinically significant anxiety for the increasing number of family carers worldwide.
越来越多的证据表明，主观照顾者负担是家庭照顾者出现临床显著焦虑的一个重要决定因素。本荟萃分析旨在综合这些证据，并调查非专业照顾者主观照顾者负担与焦虑症状之间的关系。我们检索了 PubMed、CINAHL 和 PsycINFO，截至 2020 年 1 月。使用随机效应模型获得综合估计值。经过对 4312 篇文章的筛选，纳入了 74 项研究（75 个独立样本）。主观照顾者负担与焦虑症状之间存在较大的正相关（r = 0.51；95%CI = 0.47，0.54；I2 = 0.0%）。研究设计类型（横断面研究与纵向研究）、抽样、混杂因素控制或照顾对象特征的亚组分析中未发现差异。主观照顾者负担是非专业照顾者焦虑的一个重要危险因素。针对主观照顾者负担，可能有利于预防全球范围内越来越多的家庭照顾者出现临床显著的焦虑。
