Sleep is an integral part of individuals' health and wellbeing. Despite evidence showing that social stressors are important contributors to older adults' sleep problems, how the accumulative stressful life events (SLEs) and ageing attitudes independently and jointly affect sleep quality among older adults in developing countries remains unclear. This study examined the effects of SLEs on subjectively rated sleep quality among older adults in China, and explored the potential mediating and moderating roles of positive and negative ageing attitudes on the above association. Using data from the 2014 China Longitudinal Ageing Social Survey, we had complete data for 7,780 older adults aged 60 and older. We employed logistic regression models and the Karlson–Holm–Breen decomposition method. Our findings indicated that SLEs significantly increased the risk of poor sleep quality, especially for those who had experienced two or more SLEs during the past year. Positive ageing attitudes were associated with lower odds of poor sleep quality, whereas negative ageing attitudes were related to higher odds of poor sleep quality. Moreover, the mediation analyses suggested that SLEs were associated with poor sleep quality via negative ageing attitudes. The moderating effects further documented that higher levels of positive ageing attitudes can significantly attenuate the deleterious impact of SLEs on sleep quality. The findings highlight the significance of SLEs for older adults' sleep quality and shed light on the importance of ageing attitudes to improve older adults' sleep in China as well as other low- and middle-income countries, where the social safety nets are still underdeveloped.
