Outline
To explore the time-varying association between adverse childhood experiences and social isolation in middle-aged and older adults and provide a scientific evidence for the early identification of people at risk of social isolation and the development of appropriate interventions.
Data were used from respondents who participated in the life history survey of the China Health and Retirement Longitudinal Study (CHARLS) and at least one of the surveysconducted between 2011 and 2020. Adverse childhood experienceswere collected through self-reporting and divided into four groups based on the number of adverse childhood experiences, which were categorized into the group that had not experienced adverse childhood experiences, the group that had experienced one type of adverse childhood experience, the group that had experienced two types of adverse childhood experiences, and the group that had experienced three or more types of adverse childhood experiences. A time-varying effect model was used to explore the age-varying association between adverse childhood experiences and social isolation among middle-aged and older adults, using age as the time variable.
A total of 14 397 middle-aged and older adults were included in the study. Compared with those who had not experienced adverse childhood experiences, those who had experienced one adverse childhood experience had a higher risk of social isolation between the ages of 61 and 70(OR=1.22, 95% CI:1.06-1.41); those who had experienced two adverse childhood experiences had a higher risk of social isolation between the ages of 50 and 65(OR=1.33, 95% CI: 1.13-1.57); and those who had experienced three or more adverse childhood experiences had a higher risk of social isolation between the ages of 45 and 58(OR=1.86, 95% CI:1.16-2.99).
There is aage-varyingassociation between adverse childhood experiences and social isolation among middle-aged and elderly people, with the more childhood adversities experienced, the younger the age at which social isolation occurs.
