We analysed whether care time, burden and range of caregiving tasks were associated with informal caregivers’ subjective views of ageing (measured as attitudes towards own age (ATOA), subjective age (SA), and onset of old age (OOA)), and whether these associations differed as a function of the caregivers’ age and gender. Adjusted cluster-robust fixed effects regression analyses were conducted with gender and age as moderators using data of informal caregivers (≥ 40 years) of the population-based German Ageing Survey (2014, 2017). All three aspect of care intensity were associated with changes in subjective views of ageing and this pattern was a function of the caregiver’s age and gender. Care time was significantly associated with higher SA. Care tasks were significantly associated with more positive ATOA and earlier OOA. Age moderated the association between burden and ATOA, with older adults reporting more positive ATOA. Gender moderated the association between care time and ATOA; women reported less positive ATOA than men with increasing care time, but also felt subjectively younger than men with a broader range of care tasks. Age- and gender-stratified analysis indicated further differences. Our findings suggest to reduce care time, especially among older and female caregivers, to prevent a worsening of views of ageing, while being involved in a broad range of care tasks seems to (only) benefit female caregivers.

我们分析了护理时间、负担和护理任务范围是否与非正式护理人员对衰老的主观看法（以对自己年龄（ATOA）、主观年龄（SA）和老年开始（OOA）的态度来衡量）相关，并这些关联是否因照顾者的年龄和性别而异。使用基于人口的德国老龄化调查（2014 年、2017 年）的非正式护理人员（≥ 40 岁）的数据，以性别和年龄为调节因素，进行调整后的集群稳健固定效应回归分析。护理强度的所有三个方面都与对衰老的主观看法的变化相关，并且这种模式是护理人员年龄和性别的函数。护理时间与较高的 SA 显着相关。护理任务与更积极的 ATOA 和更早的 OOA 显着相关。年龄调节了负担与 ATOA 之间的关联，老年人报告 ATOA 更积极。性别调节了护理时间和 ATOA 之间的关联；随着护理时间的增加，女性的 ATOA 积极性低于男性，但主观上感觉比男性更年轻，护理任务范围更广。年龄和性别分层分析表明存在进一步的差异。我们的研究结果表明，减少护理时间，尤其是老年护理人员和女性护理人员的护理时间，以防止对老龄化的看法恶化，而参与广泛的护理任务似乎（仅）有利于女性护理人员。
