社会互动帮助群体生活的有机体科普社会环境挑战，是生存和繁殖成功的核心。最近的研究表明，社会行为和关系可以在整个生命周期中发生变化，这种现象被称为“社会老龄化”。鉴于社会融合对健康和福祉的重要性，社会行为中与年龄有关的变化可以调节健康如何随年龄变化，并可能是个人衰老模式中无法解释的变化的重要来源。然而，将社会行为纳入老龄化研究需要更深入地了解社会行为中基于年龄的变化的原因和后果。在这里，我们概述了晚年社会性变化的驱动因素。我们认为，对社会老龄化的解释可以分为三类：（a）由于衰老而发生的社会性变化;（B）由于适应改善衰老的负面影响;和/或（c）由于年龄和人口结构变化的积极影响。量化这些过程对晚年社会性变化的相对贡献将使我们能够更全面地了解这些模式是如何以及为什么出现的，并将为社会老龄化延迟或加速其他衰老模式的潜力提供重要的见解。
Social interactions help group-living organisms cope with socio-environmental challenges and are central to survival and reproductive success. Recent research has shown that social behaviour and relationships can change across the lifespan, a phenomenon referred to as ‘social ageing’. Given the importance of social integration for health and well-being, age-dependent changes in social behaviour can modulate how fitness changes with age and may be an important source of unexplained variation in individual patterns of senescence. However, integrating social behaviour into ageing research requires a deeper understanding of the causes and consequences of age-based changes in social behaviour. Here, we provide an overview of the drivers of late-life changes in sociality. We suggest that explanations for social ageing can be categorized into three groups: changes in sociality that (a) occur as a result of senescence; (b) result from adaptations to ameliorate the negative effects of senescence; and/or (c) result from positive effects of age and demographic changes. Quantifying the relative contribution of these processes to late-life changes in sociality will allow us to move towards a more holistic understanding of how and why these patterns emerge and will provide important insights into the potential for social ageing to delay or accelerate other patterns of senescence.
